How does soil get affected by …

Continuous plantation of crops in a field makes the soil poor in certain nutrients such as nitrogen, phosphorus, potassium, etc. Plants require nutrients for their proper growth and functioning. When a farmer continues to grow’ crops one after the other, then all nutrients available in the soil reduce and the crop yield decreases automatically.

There are different methods by which nutrients in the soil can be replenished. Fertilizers and manures contain plant nutrients such as nitrogen, phosphorus, potassium. Fertilizer can be added to the soil. It helps in replenishing exhausted soils with rich sources of organic nutrients. Manure is environment friendly and replenishes the soil with organic nutrients. Compost is decomposed organic material. It reintroduces living organisms and nutrients in the soil. It improves soil structure and provides a healthy environment for plant roots.
