Most nitrogen release from organic matter occurs during the growing season, providing a steady, continuous supply of nitrogen to the crop. This is because the microorganisms responsible for releasing nitrogen from organic matter require some soil moisture. ... Soil testing helps to determine the value of this nitrogen.

Answer:

The stages of the nitrogen cycle

1. Nitrogen-fixation

Legume plants such as peas, beans and clover contain nitrogen-fixing bacteria. These bacteria live in swellings in the plant roots called nodules. Nitrogen-fixing bacteria convert nitrogen gas from the air into a form that plants can use to make proteins.

Free-living nitrogen-fixing bacteria are also found in the soil. When they die the nitrogen they have fixed into their biomass is converted into ammonium.

2. Feeding

Animals consume plant protein, digest it using specific enzymes and absorb the free amino acids.

3. Production of nitrogenous waste products

Animals cannot store excess protein in their bodies. They break it down and turn it into waste products and excrete them from their bodies.

4. Decomposition

Decomposers (some free-living bacteria and fungi) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition , nitrogen is released into the soil in the form of ammonium.

5. Nitrification

A group of free-living soil bacteria called nitrifying bacteria convert ammonium into nitrates in order to obtain energy.

6. Uptake of nitrates

Non-legume plants absorb nitrates from the soil into their roots and use the nitrates to produce their proteins.

7. Denitrification

This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.
