Soil can be enriched with essential nutrients for improving plant yield by supplying them in the form of manure and fertilizers.

Deficiency of essential nutrients can adversely affect various physiological processes in plants, including reproduction, growth, and their ability to resist diseases.

Green manure helps improve soil structure, increases organic matter content, enhances soil fertility, and reduces the need for synthetic fertilizers, promoting sustainable farming practices.

Ploughing the green plants into the soil allows them to decompose, releasing nutrients such as nitrogen and phosphorus, which are essential for crop growth.

These plants serve as green manure, enriching the soil with nutrients such as nitrogen and phosphorus.
