Ауыл шаруашылығындағы қоректік заттарды басқару
Management of nutrients in agriculture
Қоректік заттарды басқару – топырақ, өсімдік, ауа райы және гидрологиялық факторларды егіс шараларымен, суарумен, топырақ пен суды сақтау тәжірибелерімен байланыстырып, қоректік заттарды тиімді пайдалануды, өнімділікті, өсімдік сапасын және экономикалық табысты арттыруға, сонымен қатар қоршаған ортаға зиян келтіруі мүмкін қоректік заттардың (тыңайтқыштардың) жерден тысқары тасымалын азайтуға бағытталған ғылым және тәжірибе. Ол нақты бір даланың топырағы, климаты және егіс шаруашылығы жағдайларын қоректік заттардың мөлшеріне, түріне, уақытына және орнына (көбінесе 4R қоректік басқару принципі деп аталады) сәйкес келтіруді қамтиды. Қоректік заттарды басқару кезінде ескерілуі тиіс маңызды факторлар: а) қол жетімді ең жақсы өнімділік және кейбір жағдайларда өсімдік сапасын ескере отырып, қоректік заттарды қолдану; б) белгілі бір жердегі барлық көздер мен шығындарға негізделген бюджетті пайдалана отырып, қоректік заттарды басқару, қолдану және уақытын жоспарлау; және в) топырақтан қоректік заттардың шайылуын, жер бетінен ағып кетуін және булануын (немесе басқа газ алмасуларын) азайту үшін топырақ, су және өсімдіктерді басқару. Қоректік заттардың тасымалдану жолдары мен динамикасының өзгешелігіне байланысты олардың арасында өзара әсерлесулер болуы мүмкін. Мысалы, белгілі бір қоректік заттың жер бетіндегі тасымалын азайтуға бағытталған шаралар басқа қоректік заттардың шайылу жолымен шығындарын арттыруы мүмкін. Бұл күрделі динамика қоректік заттарды басқарумен айналысатын мамандарға пайданы барынша арттыру және биосферамызды сақтауға үлес қосу үшін ең жақсы тепе-теңдікті табуды талап етеді.
Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off site transport of nutrients (fertilizer) that may impact the environment. It involves matching a specific field soil, climate, and crop management conditions to rate, source, timing, and place (commonly known as the 4R nutrient stewardship) of nutrient application. Important factors that need to be considered when managing nutrients include (a) the application of nutrients considering the achievable optimum yields and, in some cases, crop quality; (b) the management, application, and timing of nutrients using a budget based on all sources and sinks active at the site; and (c) the management of soil, water, and crop to minimize the off site transport of nutrients from nutrient leaching out of the root zone, surface runoff, and volatilization (or other gas exchanges). There can be potential interactions because of differences in nutrient pathways and dynamics. For instance, practices that reduce the off site surface transport of a given nutrient may increase the leaching losses of other nutrients. These complex dynamics present nutrient managers the difficult task of achieve the best balance for maximizing profit while contributing to the conservation of our biosphere.

A crop nutrient management plan is a tool that farmers can use to increase the efficiency of all the nutrient sources a crop uses while reducing production and environmental risk, ultimately increasing profit. Increasingly, growers as well as agronomists use digital tools like SST or Agworld to create their nutrient management plan so they can capitalize on information gathered over a number of years. It is generally agreed that there are ten fundamental components of a crop nutrient management plan. Each component is critical to helping analyze each field and improve nutrient efficiency for the crops grown. These components include:
Field map The map, including general reference points (such as streams, residences, wellheads etc. ), number of acres, and soil types is the base for the rest of the plan. Soil test How much of each nutrient (N P K and other critical elements such as pH and organic matter) is in the soil profile? The soil test is a key component needed for developing the nutrient rate recommendation. Crop sequence Did the crop that grew in the field last year (and in many cases two or more years ago) fix nitrogen for use in the following years? Has long term no till increased organic matter? Did the end of season stalk test show a nutrient deficiency? These factors also need to be factored into the plan. Estimated yield Factors that affect yield are numerous and complex. A field's soils, drainage, insect, weed and crop disease pressure, rotation and many other factors differentiate one field from another. This is why using historic yields is important in developing yield estimates for next year. Accurate yield estimates can improve nutrient use efficiency. Sources and forms The sources and forms of available nutrients can vary from farm to farm and even field to field. For instance, manure fertility analysis, storage practices and other factors will need to be included in a nutrient management plan. Manure nutrient tests/analysis are one way to determine the fertility of it. Nitrogen fixed from a previous year's legume crop and residual effects of manure also affects rate recommendations. Many other nutrient sources should also be factored into this plan. Sensitive areas What's out of the ordinary about a field's plan? Is it irrigated? Next to a stream or lake? Especially sandy in one area? Steep slope or low area? Manure applied in one area for generations due to proximity of dairy barn? Extremely productive—or unproductive—in a portion of the field? Are there buffers that protect streams, drainage ditches, wellheads, and other water collection points? How far away are the neighbors? What's the general wind direction? This is the place to note these and other special conditions that need to be considered. Recommended rates Here's the place where science, technology, and art meet. Given everything you've noted, what is the optimum rate of N, P, K, lime and any other nutrients? While science tells us that a crop has changing nutrient requirements during the growing season, a combination of technology and farmer's management skills assure nutrient availability at all stages of growth. No till corn generally requires starter fertilizer to give the seedling a healthy start. Recommended timing When does the soil temperature drop below 50 degrees? Will a N stabilizer be used? What's the tillage practice? Strip till corn and no till often require different timing approaches than seed planted into a field that's been tilled once with a field cultivator. Will a starter fertilizer be used to give the seedling a healthy start? How many acres can be covered with available labor (custom or hired) and equipment? Does manure application in a farm depend on a custom applicator's schedule? What agreements have been worked out with neighbors for manure use on their fields? Is a neighbor hosting a special event? All these factors and more will likely figure into the recommended timing. Recommended methods Surface or injected? While injection is clearly preferred, there may be situations where injection is not feasible (i. e. pasture, grassland). Slope, rainfall patterns, soil type, crop rotation and many other factors determine which method is best for optimizing nutrient efficiency (availability and loss) in farms. The combination that's right in one field may differ in another field even with the same crop. Annual review and update Even the best managers are forced to deviate from their plans. What rate was actually applied? Where? Using which method? Did an unusually mild winter or wet spring reduce soil nitrate? Did a dry summer, disease, or some other unusual factor increase nutrient carryover? These and other factors should be noted as they occur. When such a plan is designed for animal feeding operations (AFO), it may be termed a "manure management plan." In the United States, some regulatory agencies recommend or require that farms implement these plans in order to prevent water pollution. The U. S. Natural Resources Conservation Service (NRCS) has published guidance documents on preparing a comprehensive nutrient management plan (CNMP) for AFOs. The International Plant Nutrition Institute has published a 4R plant nutrition manual for improving the management of plant nutrition. The manual outlines the scientific principles behind each of the four Rs or "rights" (right source of nutrient, right application rate, right time, right place) and discusses the adoption of 4R practices on the farm, approaches to nutrient management planning, and measurement of sustainability performance.

Маусым соңындағы сабақ сынағы қоректік заттардың жетіспеушілігін көрсетті ме? Бұл факторлар да жоспарға енгізілуі керек.
A crop nutrient management plan is a tool that farmers can use to increase the efficiency of all the nutrient sources a crop uses while reducing production and environmental risk, ultimately increasing profit. Increasingly, growers as well as agronomists use digital tools like SST or Agworld to create their nutrient management plan so they can capitalize on information gathered over a number of years. It is generally agreed that there are ten fundamental components of a crop nutrient management plan. Each component is critical to helping analyze each field and improve nutrient efficiency for the crops grown. These components include:
Field map The map, including general reference points (such as streams, residences, wellheads etc. ), number of acres, and soil types is the base for the rest of the plan. Soil test How much of each nutrient (N P K and other critical elements such as pH and organic matter) is in the soil profile? The soil test is a key component needed for developing the nutrient rate recommendation. Crop sequence Did the crop that grew in the field last year (and in many cases two or more years ago) fix nitrogen for use in the following years? Has long term no till increased organic matter? Did the end of season stalk test show a nutrient deficiency? These factors also need to be factored into the plan. Estimated yield Factors that affect yield are numerous and complex. A field's soils, drainage, insect, weed and crop disease pressure, rotation and many other factors differentiate one field from another. This is why using historic yields is important in developing yield estimates for next year. Accurate yield estimates can improve nutrient use efficiency. Sources and forms The sources and forms of available nutrients can vary from farm to farm and even field to field. For instance, manure fertility analysis, storage practices and other factors will need to be included in a nutrient management plan. Manure nutrient tests/analysis are one way to determine the fertility of it. Nitrogen fixed from a previous year's legume crop and residual effects of manure also affects rate recommendations. Many other nutrient sources should also be factored into this plan. Sensitive areas What's out of the ordinary about a field's plan? Is it irrigated? Next to a stream or lake? Especially sandy in one area? Steep slope or low area? Manure applied in one area for generations due to proximity of dairy barn? Extremely productive—or unproductive—in a portion of the field? Are there buffers that protect streams, drainage ditches, wellheads, and other water collection points? How far away are the neighbors? What's the general wind direction? This is the place to note these and other special conditions that need to be considered. Recommended rates Here's the place where science, technology, and art meet. Given everything you've noted, what is the optimum rate of N, P, K, lime and any other nutrients? While science tells us that a crop has changing nutrient requirements during the growing season, a combination of technology and farmer's management skills assure nutrient availability at all stages of growth. No till corn generally requires starter fertilizer to give the seedling a healthy start. Recommended timing When does the soil temperature drop below 50 degrees? Will a N stabilizer be used? What's the tillage practice? Strip till corn and no till often require different timing approaches than seed planted into a field that's been tilled once with a field cultivator. Will a starter fertilizer be used to give the seedling a healthy start? How many acres can be covered with available labor (custom or hired) and equipment? Does manure application in a farm depend on a custom applicator's schedule? What agreements have been worked out with neighbors for manure use on their fields? Is a neighbor hosting a special event? All these factors and more will likely figure into the recommended timing. Recommended methods Surface or injected? While injection is clearly preferred, there may be situations where injection is not feasible (i. e. pasture, grassland). Slope, rainfall patterns, soil type, crop rotation and many other factors determine which method is best for optimizing nutrient efficiency (availability and loss) in farms. The combination that's right in one field may differ in another field even with the same crop. Annual review and update Even the best managers are forced to deviate from their plans. What rate was actually applied? Where? Using which method? Did an unusually mild winter or wet spring reduce soil nitrate? Did a dry summer, disease, or some other unusual factor increase nutrient carryover? These and other factors should be noted as they occur. When such a plan is designed for animal feeding operations (AFO), it may be termed a "manure management plan." In the United States, some regulatory agencies recommend or require that farms implement these plans in order to prevent water pollution. The U. S. Natural Resources Conservation Service (NRCS) has published guidance documents on preparing a comprehensive nutrient management plan (CNMP) for AFOs. The International Plant Nutrition Institute has published a 4R plant nutrition manual for improving the management of plant nutrition. The manual outlines the scientific principles behind each of the four Rs or "rights" (right source of nutrient, right application rate, right time, right place) and discusses the adoption of 4R practices on the farm, approaches to nutrient management planning, and measurement of sustainability performance.

In the United States, some regulatory agencies recommend or require that farms implement these plans in order to prevent water pollution. The U. S. Natural Resources Conservation Service (NRCS) has published guidance documents on preparing a comprehensive nutrient management plan (CNMP) for AFOs. The International Plant Nutrition Institute has published a 4R plant nutrition manual for improving the management of plant nutrition. The manual outlines the scientific principles behind each of the four Rs or "rights" (right source of nutrient, right application rate, right time, right place) and discusses the adoption of 4R practices on the farm, approaches to nutrient management planning, and measurement of sustainability performance.

A crop nutrient management plan is a tool that farmers can use to increase the efficiency of all the nutrient sources a crop uses while reducing production and environmental risk, ultimately increasing profit. Increasingly, growers as well as agronomists use digital tools like SST or Agworld to create their nutrient management plan so they can capitalize on information gathered over a number of years. It is generally agreed that there are ten fundamental components of a crop nutrient management plan. Each component is critical to helping analyze each field and improve nutrient efficiency for the crops grown. These components include:

A crop nutrient management plan is a tool that farmers can use to increase the efficiency of all the nutrient sources a crop uses while reducing production and environmental risk, ultimately increasing profit. Increasingly, growers as well as agronomists use digital tools like SST or Agworld to create their nutrient management plan so they can capitalize on information gathered over a number of years. It is generally agreed that there are ten fundamental components of a crop nutrient management plan. Each component is critical to helping analyze each field and improve nutrient efficiency for the crops grown. These components include:
Field map The map, including general reference points (such as streams, residences, wellheads etc. ), number of acres, and soil types is the base for the rest of the plan. Soil test How much of each nutrient (N P K and other critical elements such as pH and organic matter) is in the soil profile? The soil test is a key component needed for developing the nutrient rate recommendation. Crop sequence Did the crop that grew in the field last year (and in many cases two or more years ago) fix nitrogen for use in the following years? Has long term no till increased organic matter? Did the end of season stalk test show a nutrient deficiency? These factors also need to be factored into the plan. Estimated yield Factors that affect yield are numerous and complex. A field's soils, drainage, insect, weed and crop disease pressure, rotation and many other factors differentiate one field from another. This is why using historic yields is important in developing yield estimates for next year. Accurate yield estimates can improve nutrient use efficiency. Sources and forms The sources and forms of available nutrients can vary from farm to farm and even field to field. For instance, manure fertility analysis, storage practices and other factors will need to be included in a nutrient management plan. Manure nutrient tests/analysis are one way to determine the fertility of it. Nitrogen fixed from a previous year's legume crop and residual effects of manure also affects rate recommendations. Many other nutrient sources should also be factored into this plan. Sensitive areas What's out of the ordinary about a field's plan? Is it irrigated? Next to a stream or lake? Especially sandy in one area? Steep slope or low area? Manure applied in one area for generations due to proximity of dairy barn? Extremely productive—or unproductive—in a portion of the field? Are there buffers that protect streams, drainage ditches, wellheads, and other water collection points? How far away are the neighbors? What's the general wind direction?

Азотты басқару
Өсімдіктердің 16 қажетті қоректік затының ішінде азотты далалық егіс жүйелерінде басқару әдетте ең қиынға соғады. Бұл себебі, өсімдіктерге қолжетімді азот мөлшері топырақтағы судың жағдайына байланысты жылдам өзгеріп отыруы мүмкін. Азот өсімдік-топырақ жүйесінен төмендегі бір немесе бірнеше процестер арқылы жоғалуы мүмкін: сіңіру; жер бетінен ағызу; топырақ эрозиясы; аммиактың булануы; және денитрификация.
Of the 16 essential plant nutrients, nitrogen is usually the most difficult to manage in field crop systems. This is because the quantity of plant available nitrogen can change rapidly in response to changes in soil water status. Nitrogen can be lost from the plant soil system by one or more of the following processes: leaching; surface runoff; soil erosion; ammonia volatilization; and denitrification.
Азотты тиімділікті арттыратын азотты басқару әдістері
Азотты басқару мақсаты – егіндердің қолданған азотты тиімді пайдалануын барынша арттыру. Азотты тиімді пайдаланудың жақсаруы топырақтан азоттың жоғалтуының азаюымен байланысты. Жоғалтуларды толығымен болдырмау мүмкін болмаса да, егін өндірісінде төмендегі бір немесе бірнеше басқару шараларын қолдану арқылы маңызды жақсартуларға қол жеткізуге болады.
Nitrogen management aims to maximize the efficiency with which crops use applied N. Improvements in nitrogen use efficiency are associated with decreases in N loss from the soil. Although losses cannot be avoided completely, significant improvements can be realized by applying one or more of the following management practices in the cropping system.
N қолданбалардың уақыты
N-ді өсімдіктер пайдалана алатын уақытқа жақын қолданыңыз. N-нің ең қарқынды сіңірілу кезеңіне жақын жақтан қоректендіру үшін N қолданыңыз. Бірнеше рет қолдану, қолданылған N-ді тиімді пайдалануға және N-нің қоршаған ортаға жоғалу қаупін азайтуға мүмкіндік береді.
Apply N close to the time when crops can utilize it. Make side dress N applications close to the time of most rapid N uptake. Split applications, involving more than one application, allow efficient use of applied N and reduce the risk of N loss to the environment.
N Нысандар, оның ішінде баяу немесе бақыланатын босатылатын тыңайтқыштар мен ингибиторлар
Баяу немесе басқарылатын шығарылымды тыңайтқыштар азоттың өсімдікке сіңуіне қолайлы уақытқа дейін қолжетімділігін кешіктіреді. Топырақтағы нитрат концентрациясын шектеу арқылы азоттың денитрификация және шайылу арқылы жоғалу қаупі азаяды. Нитрификация тежегіштері қолданған азотты аммоний түрінде ұзақ уақыт сақтап, шайылу мен денитрификациядан болатын жоғалтуларды азайтады.
Slow or controlled release fertilizer delays the availability of nitrogen to the plant until a time that is more appropriate for plant uptake the risk of N loss through denitrification and leaching is reduced by limiting nitrate concentrations in the soil. Nitrification inhibitors maintain applied N in the ammonium form for a longer period of time, thereby reducing leaching and denitrification losses.
N аулау
Өсімдіктердің белгілі бір сорттары топырақтан азотты тиімдірек сіңіріп, азотты пайдалану тиімділігін арттыра алады. Азотты тиімді қабылдау үшін өсімдіктерді селекциялау жұмыстары жүргізілуде. Терең тамырлы дақылдармен кезектестіру топырақ профилінің терең қабаттарындағы нитраттарды жинауға көмектеседі. Жапқыш дақылдар егін жинаудан кейін қалған азотты жинап, оны өсімдік биомассасы ретінде қайта пайдаланады. Топырақтың терең қабаттарындағы тамыр дамуына кедерес жасайтын факторларды жою; топырақтың терең қабаттарының тығыздалуы және қышқылдығы көптеген аймақтарда тамырлардың тереңге енуіне тосқауыл қойып, денитрификация мен шайылуға бейім нитраттардың топырақта жиналуына әкеледі. Тиісті өсімдік тығыздығы мен аралық қашықтықты қамтамасыз ету және арамшөптер мен зиянкестерді тиімді басқару сияқты жақсы агрономиялық шаралар өсімдіктерге азотты сіңіруді және өнімділікті арттыру үшін кең тамыр жүйесін дамытуға мүмкіндік береді.
Particular crop varieties are able to more efficiently extract N from the soil and improve N use efficiency. Breeding of crops for efficient N uptake is in progress. Rotation with deep rooted crops helps capture nitrates deeper in the soil profile. Cover crops capture residual nitrogen after crop harvest and recycle it as plant biomass. Elimination of restrictions to subsoil root development; subsoil compaction and subsoil acidity prevent root penetration in many subsoils worldwide, promoting build up of subsoil nitrate concentrations which are susceptible to denitrification and leaching when conditions are suitable. Good agronomic practice, including appropriate plant populations and spacing and good weed and pest management, allows crops to produce large root systems to optimise N capture and crop yield.
Қорғау мақсатындағы жер өңдеу
Қорғаушы тілемдеу топырақтың ылғалдылығын жақсартады, бұл су пайдалану тиімділігін арттырады; су тапшылығы жағдайында, бұл қолданылған тыңайтқыштың бір бірлігіне шаққандағы егін өнімділігін жақсартады.
Conservation tillage optimizes soil moisture conditions that improve water use efficiency; in water stressed conditions, this improves crop yield per unit N applied.
N тыңайтқыштарды қолдану әдісі мен орналастыруы
Жоталы дақылдарда N тыңайтқыштарын жоталарға бау-бау етіп салу N-нің шайылуға бейімделуін азайтады. Инжекторлар сияқты, тығыз топырақ қабаты мен жер беті жотасын жасайтын қатарлық тыңайтқыш себу машиналарын қолдану, су ағынын өзгерту арқылы N шығындарын азайтуға мүмкіндік береді.
In ridged crops, placing N fertilizers in a band in ridges makes N less susceptible to leaching. Row fertilizer applicators, such as injectors, which form a compacted soil layer and surface ridge, can reduce N losses by diverting water flow.
Суаруды дұрыс басқару газды тиімді пайдалануды арттырады
Топырақтың ылғалдылығын бағалау және өсімдіктердің күнделікті қажеттіліктеріне сүйенетін жоспарлы суару, су және азотты пайдалану тиімділігін арттырады. Спринклерлік суару жүйелері, саңылаулы немесе тоғандық суару жүйелерімен салыстырғанда, суды біркелкірек және аз көлемде қолданады. Саңылаулы суару тиімділігін суару уақытын, ағын мөлшерін, саңылау ұзындығын реттеу, қатарларды кезекпен суару немесе импульстік клапандарды қолдану арқылы жақсартуға болады. Кезекпен суару және тыңайтқыш қолдану, судың қоректік заттармен тікелей жанасуын азайтады. Суару жүйелері арқылы азотты тыңайтқыш қолдану (фертигация), өсімдіктердің ең көп қажеттілік сезінетін кезде азотпен қамтамасыз етуді жеңілдетеді. Саңылаулы суару кезінде полиакриламид (PAM) қолдану, шөгінділердің және азоттың жоғалуын азайтады.
Scheduled irrigation based on soil moisture estimates and daily crop needs will improve both water use and N use efficiency. Sprinkler irrigation systems apply water more uniformly and in lower amounts than furrow or basin irrigation systems. Furrow irrigation efficiency can be improved by adjusting set time, stream size, furrow length, watering every other row, or the use of surge valves. Alternate row irrigation and fertilization minimizes water contact with nutrients. Application of N fertilizer through irrigation systems (fertigation) facilitates N supply when crop demand is greatest. Polyacrylamide (PAM) treatment during furrow irrigation reduces sediment and N losses.

Кейбір топырақ асты суару жүйелері топырақтан шайылып кеткен нитратты қайта пайдаланып, дренаждық суға түсетін нитраттың мөлшерін азайтады. Шамадан тыс дренаж судың жылдам өтуіне және азоттың шайылуына алып келуі мүмкін, бірақ шектеулі немесе жеткіліксіз дренаж анаэробтық ортаны және денитрификацияны күшейтеді.
Some subirrigation systems recycle nitrate leached from the soil profile and reduce nitrate lost in drainage water. Excessive drainage can lead to rapid through flow of water and N leaching, but restricted or insufficient drainage favors anaerobic conditions and denitrification.
Симуляциялық модельдерді қолдану
Өсімдіктерге қолжетімді азоттың (N) күйіндегі қысқа мерзімді өзгерістер көп жағдайда егіннің азотқа қажеттілігін маусымдық түрде дұрыс болжауды қиындатады. Дегенмен, топырақ, ауа райы, егін және шаруашылық басқару деректерін пайдаланатын модельдер (мысалы, NLEAP және Adapt N) күнделікті өзгерістермен жаңартылып, қолданған азоттың тағдырын болжауды жақсарта алады. Бұл фермерлерге азотты тиімді пайдалануды арттырып, азоттың жоғалуын және қоршаған ортаға тигізетін зиянын азайта отырып, пайдалылығын арттыруға мүмкіндік беретін икемді басқару шешімдерін қабылдауға көмектеседі.
Short term changes in the plant available N status make accurate seasonal predictions of crop N requirement difficult in most situations. However, models (such as NLEAP and Adapt N) that use soil, weather, crop, and field management data can be updated with day to day changes and thereby improve predictions of the fate of applied N. They allows farmers to make adaptive management decisions that can improve N use efficiency and minimize N losses and environmental impact while maximizing profitability.
Сақтау буферлері
Буферлер аммиак және органикалық азотты қамтитын шөгінділерді тоқтатады. Жер асты ағынындағы нитрат, буферлік өсімдіктермен байланысты топырақтағы көміртек энергия көздерімен күшейтілген денитрификация арқылы азаяды. Буферлік өсімдіктер азотты және басқа да қоректік заттарды сіңіріп алып, суға жоғалуын қысқартады.
Buffers trap sediment containing ammonia and organic N.
Nitrate in subsurface flow is reduced through denitrification enhanced by carbon energy sources contained in the soil associated with buffer vegetation. Buffer vegetation takes up nitrogen, other nutrients, and reduces loss to water.

Құрылыспен салынған ылғалды жерлер
Ландшафт бойынша стратегиялық түрде орналасқан жасалма сулы-сазды жерлер дренаждық суларды тазалап, беттік суларға шөгінділер мен нитраттардың мөлшерін азайтады.
Constructed wetlands located strategically on the landscape to process drainage effluent reduces sediment and nitrate loads to surface water.
