Growing Potatoes with Slow-release Nitrogen Fertilizer
Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

متن کاملIncorporating Controlled - Release Fertilizer Technology into Outplanting
The application of controlled-release fertilizers (CRF) at the time of planting offers a means to improve the establishment of forest tree seedlings. As compared to conventional fertilizers, the gradual pattern of nutrient release from CRF may better coincide with plant needs, minimize leaching, and improve fertilizer use efficiency. Many different CRF types are available and products differ in...
متن کاملImpact of controlled release urea on maize yield and nitrogen use efficiency under different water conditions
Controlled release urea (CRU) has been widely adopted to increase nitrogen (N) use efficiency and maize production, but the impacts can range widely depending on water availability in the soil. In an experiment using Zhengdan 958 (a popular summer maize hybrid), three levels of water treatments (adequate water condition [W3], which maintained soil moisture at about 75% ± 5% of the soil's field ...
متن کاملEvaluation of water pollution from rice cultivation using Nitrogen fertilizer in North of Iran
The increase of nitrite and nitrate concentrations in surface and groundwater is a greatconcern in our lives nowadays. Nitrate and nitrite in drinking water normally originate fromagricultural operation and chemical fertilizers. Therefore, the present study aims toinvestigate the effect of nitrogen fertilizers used in rice cultivation and levels of nitrate andnitrite in farm wastewater and wate...
