Which of the following practices improves crop yield in a clayey soil? Addition of
Answer Details
The practice that improves crop yield in a clayey soil is the addition of lime and humus. Clayey soils are often compact and have low nutrient levels, making it difficult for crops to grow properly. The addition of lime helps to reduce the acidity of the soil, which can be toxic to plants. The addition of humus helps to increase the organic matter content of the soil, which can improve soil structure and nutrient availability. Both lime and humus can help to improve soil fertility, making it easier for crops to grow and produce a higher yield.
