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

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

    However, the excessive or inefficient use of nitrogen fertilizers can lead to environmental problems such as nitrogen leaching, runoff, and emissions of nitrogen oxides (NOx). [4] Nitrogen leaching occurs when nitrogen compounds, primarily nitrates , move through the soil profile and enter groundwater, potentially contaminating drinking water ...

  3. Nutrient management - Wikipedia

    en.wikipedia.org/wiki/Nutrient_management

    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 ...

  4. Organic fertilizer - Wikipedia

    en.wikipedia.org/wiki/Organic_fertilizer

    Grain meals can be made of corn gluten, alfalfa, cottonseed, or soybean. Most supply nitrogen and potassium, but soybean meal provides nitrogen and phosphorus. [27] When initially spread they can cause an increase in ammonia within the soil and burn seeds, it is recommended to use these after plants have developed, to ensure crop success.

  5. Controlled atmosphere - Wikipedia

    en.wikipedia.org/wiki/Controlled_atmosphere

    A controlled atmosphere is an agricultural storage method in which the concentrations of oxygen, carbon dioxide and nitrogen, as well as the temperature and humidity of a storage room are regulated. Both dry commodities and fresh fruit and vegetables can be stored in controlled atmospheres.

  6. Biofertilizer - Wikipedia

    en.wikipedia.org/wiki/Biofertilizer

    Extensive use of agrochemicals in agricultural practices has been found to cause environmental disturbances and public health hazards affecting food security and sustainability in agriculture. [22] Biofertilizers offers an alternative solution for such agrochemicals, and show yield increase of up to about 10–40% by increasing protein contents ...

  7. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    Although nitrogen makes up most of the atmosphere, it is in a form that is unavailable to plants. Nitrogen is the most important fertilizer since nitrogen is present in proteins (amide bonds between amino acids), DNA (puric and pyrimidic bases), and other components (e.g., tetrapyrrolic heme in chlorophyll). To be nutritious to plants, nitrogen ...

  8. Nutrient budgeting - Wikipedia

    en.wikipedia.org/wiki/Nutrient_budgeting

    An accurate nutrient budget is an important tool to provide an early indication of potential problems arising from (i) a nutrient surplus (inputs>outputs), leading to an accumulation of nutrients and increased risk of loss or (ii) a deficit (outputs>inputs), depleting nutrient reserves and increasing the risk of deficiencies and reduced crop yields.

  9. Biointensive agriculture - Wikipedia

    en.wikipedia.org/wiki/Biointensive_agriculture

    Biointensive Mini-Farming Journal of Sustainable Agriculture (Vol. 19 (2), 2001, p. 81-83) shows that biointensive methods can enable small-scale farms and farmers to significantly increase food production and income, utilize predominantly local, renewable resources and decrease expense and energy inputs while building fertile topsoil at a rate ...
