What factors influence soil fertility in agriculture?
pH and soil structure
Organic matter content and nutrient availability
Soil texture and drainage
All of the above
Correct answer is D
Soil fertility is influenced by a variety of factors including organic matter content, nutrient availability, pH, soil structure, soil texture, and drainage. Organic matter content and nutrient availability provide the necessary nutrients for plant growth. pH affects the availability of nutrients in the soil. Soil structure affects the soil's ability to hold and supply water, air, and nutrients to plants. Soil texture affects the soil's physical properties and its ability to hold and supply water, air, and nutrients to plants. Drainage affects the soil's ability to supply sufficient water to plants without waterlogging the roots.
