Production of slow-released nitrogen fertilizer from urine

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...

Fertilizer NPK from human urine and olive oil mill wastewaters

The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...

Nitrous Oxide Emissions from Claypan Soils Due to Nitrogen Fertilizer Source and Tillage/fertilizer Placement Practices

Evaluation 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...
