  • What Are the Effects of Leaching? Sciencing

    EffectsIssuesBenefitsAs water moves down through the soil, it carries away some of the nutrients that plants use, such as nitrates and sulfur. This process is called leaching. Under normal circumstances, minor levels of leaching occur with typical rainfall, and the breakdown of organic materials on the surface resupplies the soil. In the case of excessive rainfall or irrigation, the effects of soil leaching can be more dramatic. Like a swimming pool, soil maintains a pH level. In essence, lower pH means higher acidity.
