The Illinois Soil Nitrogen Test ("ISNT") is a method for measuring the amount of Nitrogen in soil that is available for use by plants as a nutrient. The test predicts whether the addition of nitrogen fertilizer to agricultural land will result in increased crop yields. [1] [2] Nitrogen is essential for plant development.
When discussing the application of nitrogen in agriculture, it is essential to consider the sources of nitrogen used. Synthetic nitrogen fertilizers, such as ammonium nitrate and urea, are commonly applied to crops to replenish soil nitrogen levels and enhance crop productivity [3] These fertilizers provide readily available nitrogen for plant ...

Blue-green algae belonging to the cyanobacteria genera Nostoc, Anabaena, Tolypothrix, and Aulosira fix atmospheric nitrogen and are used as inoculants for paddy crops grown in both upland and lowland conditions. Anabaena, in association with the water fern Azolla, can contribute nitrogen up to 60 kg/ha/season and can also enrich soils with ...
Approximately 78% of Earth's atmosphere is N gas (N 2), which is an inert compound and biologically unavailable to most organisms.In order to be utilized in most biological processes, N 2 must be converted to reactive nitrogen (Nr), which includes inorganic reduced forms (NH 3 and NH 4 +), inorganic oxidized forms (NO, NO 2, HNO 3, N 2 O, and NO 3 −), and organic compounds (urea, amines, and ...
