True or False? Potassium is easily leached through sandy soil.

Potassium is indeed considered to be easily leached through sandy soil, making the statement true. Sandy soils have larger particles and larger pore spaces compared to other soil types, such as clay or loam, which allows water to drain rapidly. As water moves through sandy soil, it can carry away nutrients, including potassium, which is a key nutrient for plant growth. This is particularly true during heavy rainfall or irrigation when water flows through the soil, washing away soluble potassium ions before they can be absorbed by plant roots.

In contrast, soils with finer textures, such as clay, tend to retain nutrients better due to their higher cation exchange capacity and smaller pore sizes, which slows down the movement of water and nutrients. Thus, while potassium can be leached from various soil types, sandy soil is particularly prone to this due to its inherent characteristics.
