  2. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Soil acidification is the buildup of hydrogen cations, which reduces the soil pH. Chemically, this happens when a proton donor gets added to the soil. The donor can be an acid, such as nitric acid, sulfuric acid, or carbonic acid. It can also be a compound such as aluminium sulfate, which reacts in the soil to

  3. Alkali soil - Wikipedia

    en.wikipedia.org/wiki/Alkali_soil

    Spent acid (HCl, H 2 SO 4, etc.) can also be used to reduce the excess Na 2 CO 3 in the soil/water. Where urea is made available cheaply to farmers, it is also used to reduce the soil alkalinity / salinity primarily. [11] The ammonium (NH + 4) cation produced by urea hydrolysis which is a strongly sorbing cation exchanges with the weakly ...

    The briquettes (either urea- or NPK-based) are then placed in a plant's root zone, as opposed to the traditional application method of broadcasting. Trials have shown that FDP and UDP (when only urea is used) can increase crop production up to 36 percent, reduce fertilizer use by up to 38 percent, and reduce nitrogen losses by up to 40 percent ...

  5. Nutrient management - Wikipedia

    Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. 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 ...

  6. Soil conservation - Wikipedia

    en.wikipedia.org/wiki/Soil_conservation

    The use of pesticides can contaminate the soil, and nearby vegetation and water sources for a long time. They affect soil structure and (biotic and abiotic) composition. [9] [10] Differentiated taxation schemes are among the options investigated in the academic literature to reducing their use. [11

  7. Nitrogen and Non-Protein Nitrogen's effects on Agriculture

    en.wikipedia.org/wiki/Nitrogen_and_Non-Protein...

    Even though nitrogen is a necessary element for life, too much of it in water can have negative effects on aquatic ecosystems and endanger human health. Agricultural runoff, where fertilizers containing nitrogen compounds can seep into rivers, lakes, and groundwater, is one of the main sources of nitrogen in water.

  9. Ammonia volatilization from urea - Wikipedia

    en.wikipedia.org/wiki/Ammonia_volatilization...

    The soil's pH also has a strong effect on the amount of volatilization. Specifically, highly alkaline soils (pH~8.2 or higher) have proven to increase urea hydrolysis. One study has shown complete hydrolysis of urea within two days of application on such soils. In acidic soils (pH 5.2) the urea took twice as long to hydrolyze. [7]
