What is animal and green manure?
Adding Organic Matter to Soil noncomposted plant and animal material—common examples are leaves and garden waste, or fresh animal manure. green manure—fresh plant material grown purposely to be incorporated into the soil on the site where it was grown.
Is green manure organic or inorganic?
Organic manures are animal manure and green manure. Organic manures improve the structure of the soil. Plants grow better in a soil of good structure, and the chemical fertilizers are used better.
Is green manure an organic mineral source?
In organic production, only organic fertilizers (compost, manure, and green manure) are applied; in such case, nitrogen is less available to plants. Organic fertilizer in the soil is first decomposed by microorganisms and edaphon; next, humus is created, which is composed of the organic–mineral compounds.
What environmental pollution can be caused by excessive use of fertilizer?
Over-fertilization (excessive use of fertilizers) (i.e., the application of fertilizer nitrogen (N) in excess of the tree or vine capacity to use it for optimum productivity) is associated with high levels of residual nitrate in the soil, which potentially contribute to groundwater and atmospheric pollution as a result …

- Increased Air Pollution. An ice berg melting due to increased water surface temperature.
- Soil Acidification.
- Mineral Depletion.
What are the negative effects of fertilizer?
However, excessive use of chemical fertilizers has led to several issues such as serious soil degradation, nitrogen leaching, soil compaction, reduction in soil organic matter, and loss of soil carbon.
