What is crop rotation? Write it's Importance Class 8
Answers
Explanation:
Crop rotation: Different crops require different nutrients. Therefore, farmers plant different crops each season. This is called crop rotation. It prevents depletion of nutrients in the soil.
Why Is Crop Rotation Important?
Crop rotation helps to maintain soil structure and nutrient levels and to prevent soilborne pests from getting a foothold in the garden.
When a single crop is planted in the same place every year, the soil structure slowly deteriorates as the same nutrients are used time and time again. After a few years, the soil becomes unhealthy, drained of those specific nutrients. Simultaneously, insect pests that feed on the single crop—and that spend their larval stage in the soil—become more prolific as their food source remains. These pests become harder to manage every year as their population increases.
Answer:
Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons.
1) The soil fertility is maintained for a prolonged period.
2) The growth of weeds and pests is prevented.
3) A lot of chemical fertilizers are not required.
4) The physical and chemical nature of the soil remains unaltered.
