Nitrogen is added to the soil and lost from it when it undergoes a number of transformations. A small portion of nitrogen gas is directly assimilated by symbiotic and non- symbiotic nitrogen fixing bacteria and also by blue-green algae, to synthesize their cell protoplasm. Proteins present in organic matter as well as in the bodies of soil microorganisms are decomposed [...]
This article throws light upon the six main factors that affect nitrogen loss through de-nitrification. The factors are: 1. Organic Matter 2. Moisture Content 3. Aeration 4. Soil Reaction 5. Amount of Nitrate Present 6. Temperature. Factor # 1. Organic Matter: Because denitrifying bacteria require organic matter as a source of carbon (and nitrogen) for their activity, the nature and [...]
