Which of the following is a characteristic influencing nutrient retention in soil?

Soil properties are fundamental determinants in nutrient retention because they influence the physical and chemical characteristics of the soil that affect how nutrients behave within the soil matrix. Factors such as soil texture, organic matter content, pH, and cation exchange capacity all contribute to the capacity of the soil to hold onto nutrients.

For instance, soils with high organic matter content or clay-rich soils typically have greater nutrient retention capabilities because they can hold more moisture and nutrients through their complex structure and surface area. Conversely, sandy soils tend to have lower nutrient retention because of their larger particle size and greater drainage capacity, which allows nutrients to leach away more easily.

Understanding these soil properties is key for effective nutrient management in agricultural practices, ensuring that crops receive the necessary nutrients while minimizing the risk of nutrient loss to the environment.
