Leaching is the process by which water moves soluble nutrients, salts, or chemicals downward through the soil, potentially reaching groundwater. While leaching can remove excess salts from the root zone, it can also result in the loss of valuable nutrients, such as nitrogen, which can negatively impact plant growth. Managing leaching through proper irrigation, fertilization, and soil management is essential for maintaining soil health and preventing nutrient depletion or contamination of water sources.
