In which type of soil are pesticides more likely to leach through?

Sandy soil, characterized by larger particle sizes and lower organic matter content, allows for quicker drainage and less absorption of water. This means that when pesticides are applied to sandy soil, they are more likely to move downward through the soil profile, especially during rainfall or irrigation events. The larger spaces between sand particles create pathways for liquid to flow, facilitating the leaching process.

In contrast, other soil types such as clay soil may retain water and pesticides due to their smaller particle size and higher surface area, which increases adsorption. Loamy soil, being a balanced mixture of sand, silt, and clay, holds moisture well and can also retain pesticides more effectively than sandy soil. Peaty soil, known for its richness in organic materials, typically has a high capacity for retaining water and nutrients, further reducing the likelihood of leaching.

Therefore, sandy soil, with its unique properties, is indeed the type in which pesticides are more likely to leach through.
