  4. Illinois Soil Nitrogen Test - Wikipedia

    en.wikipedia.org/wiki/Illinois_Soil_Nitrogen_Test

    The ISNT is a new (2007) method for measuring nitrogen available for plant uptake. ISNT estimates the amount of nitrogen present in the soil as amino sugar nitrogen. With respect to corn and soybeans, the optimal range for plant growth appears to be around 225 to 240 mg/Kg. Some form of nitrogen fertilizer is needed if levels are below this ...

    The nitrophosphate process (also known as the Odda process) is a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927. The process involves acidifying phosphate rock with dilute nitric acid to produce a mixture of phosphoric acid and calcium nitrate.

    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.
