To mitigate these environmental impacts, various nitrogen management strategies are employed in agriculture. Soil testing is an essential practice that helps farmers assess the nutrient status of their soils and determine appropriate fertilizer application rates. Nutrient management plans based on soil test results help optimize fertilizer use ...
Foliar application has been shown to avoid the problem of leaching-out in soils and prompts a quick reaction in the plant. Foliar application of phosphorus, zinc and iron brings the greatest benefit in comparison with addition to soil where phosphorus becomes fixed in a form inaccessible to the plant [5] and where zinc and iron are less available.
Generally, the crop requires modest application of nitrogen fertilizer, as it is not a heavy feeder. Typical nitrogen (N) content of senescent material in the fall is 0.5% N. Fertilizer nitrogen applications of about 5 kg N/hectare (ha) applied for each tonne of biomass removed is a general guideline.
Through the increasing use of nitrogen fertilizer, which was used at a rate of about 110 million tons (of N) per year in 2012, [132] [133] adding to the already existing amount of reactive nitrogen, nitrous oxide (N 2 O) has become the third most important greenhouse gas after carbon dioxide and methane.
Nitrogen is the most critical element obtained by plants from the soil, to the exception of moist tropical forests where phosphorus is the limiting soil nutrient, [36] and nitrogen deficiency often limits plant growth. [37] Plants can use nitrogen as either the ammonium cation (NH 4 +) or the anion nitrate (NO 3 −).

"Milorganite" is a portmanteau of the term Milwaukee Organic Nitrogen. It was the winning entry in a 1925 naming contest for a biosolids-based fertilizer held in National Fertilizer Magazine. Its history began with Milwaukee's goal to clean up its rivers and Lake Michigan.
