Question

how can soil depicted of nutrients be made once again rich in nutrients without using manure or fertilizer​

Answer 1

Answer:

Processes like fallowing and mulching will help in enriching the nutrients that have been depicted in the soil without using any manure or fertilizer. Explanation:

• Fallowing is maintaining the field without any cropping for one season to regain its natural vitality.
• Mulching is the process where the field is covered by organic matter like grass, twigs, leaves, coffee grounds, straw, corn, cobs etc which will get decomposed into organic manure or humus and will increase soil fertility.
• Mulching will increase the worm content of the soil which in turn will aerate the soil. Mulching also will prevent soil and water erosion.
