Question

How are nutrients replenished in the soil?

Answer 1

Fertile soil produces higher yields and greater plant quality. Fertile soil is rich in essential components and minerals, has good aeration, holds water well, and has a pleasant texture.

Nutrient Replenishment

Nutrients can be replenished in the following ways:

• Fertilisers and manures contain plant nutrients such as nitrogen, phosphorous and potassium, etc. So, when fertilisers and manures are added to the soil in the fields, then the soil gets enriched with nutrients like nitrogen, phosphorous and potassium, etc.
• Nutrients are replenished by certain different microorganisms that are found in the soil or also by the death of certain bacteria such as the rhizobium.
