Suggest the three method of replenishing nutrient in the soil
Answers
Answer:
Nutrients are replenished by certain different microorganism that are found in the soil or also by the death of certain plants such as the rhizobium bacteria. The decaying plants tend to slowly break down into the basic soil nutrients over a period of time.

Answer:
Methods of "replenishing nutrients" in the soil are:
a. Composting: Addition of organic naturally decayed matter in the "form of compost" or aged manure are either tilled or sprayed. The organic matter helps plants to absorb the soil nutrients.
b. Cover crops: Mulch or cover crops are grown in between "growing seasons". These are called as green manure or green mulch that helps prevent "soil erosion" and nutrient leaching, increases the soil organic and living content, and controls pests. Mustard and legumes like alfalfa and peas are mostly used as "cover crops". The rhizobium that symbiotically grows with leguminous plants helps the plants to fix non-absorbable nitrogen from the soil.
c. Crop rotation: can be done in a planned order according to the crop seasons to prevent soil depletion and increase soil health. This method also helps to increase yield and decrease crop loss due to diseases.
