Worked Solution & Example Answer:Explain the term crop rotation - Leaving Cert Agricultural Science - Question b - 2013
Step 1
Explain the term crop rotation.
Answer
Crop rotation is the agricultural practice of growing different crops in a specific sequence on the same piece of land over several years. This method disrupts the cycle of pests and diseases, improves soil fertility, and minimizes soil erosion. By alternating crops, farmers can enhance soil health and optimize nutrient use.
Step 2
Name two crops that are commonly used in crop rotation and give a reason why each is used.
Answer
- Legumes: These crops, such as peas and beans, are often used in crop rotation because they add nitrogen back into the soil. Nitrogen is a vital nutrient that benefits subsequent crops.
- Potatoes: Potatoes are commonly rotated to help break the cycles of diseases and pests that affect other crops. Additionally, they have different nutrient requirements, which helps maintain soil health.
