Paragraph on “Crop Rotation” complete paragraph for Class 9, Class 10, Class 11 and Class 12
Crop Rotation
Different types of plants take in different types of minerals from the soil while growing. This makes it necessary to re-vitalise the soil regularly. In the earlier days farmers divided their fields into three parts, they did not grow any crops in one of the three parts in rotation. The objective of this was to allow one of the patches of land to re-vitalise itself during that year and be ready for planting the next year. Other farmers divided their land into smaller parts and grew a different crop in each patch each year. Since fertilisers are available today, crop rotation is no longer done in countries where intensive farming is carried out but farmers still use these techniques in poorer and developing countries where fertilisers are not available in large quantities.
