It involves implementing safety procedures, using protective equipment, regularly maintaining machinery, and adhering to safety regulations to reduce risks associated with agricultural operations.

16. Explain different types of soil and their suitability for various crops.

    • Answer: Soil types vary based on texture (sand, silt, clay), structure, and organic matter content. Sandy soils drain quickly, suitable for crops needing good drainage. Clay soils retain water but can be poorly drained. Loam soils are a balanced mix, ideal for many crops. Crop selection should consider soil type to maximize yields.

17. How can you contribute to sustainable agriculture?
