Leaching (agriculture) - Wikipedia

In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.Leaching may also refer to the practice of applying a small amount of excess irrigation where the water has a high salt content to ...

Water quality for agriculture

In Example 1, the leaching fraction and water quality are used to predict drainage water quality. The plant, however, is only exposed to this drainage water salinity at the lowest part of the root zone. The salinity in this lower portion of the root zone tends to be higher than in the upper portion due to its much lower leaching fraction.

Water quality for agriculture

Lapsed time for the rise and fall of the water table is 2–5 days. The upward movement of the water tends to concentrate salts on or near the surface irrespective of whether the salinity originates from the water table or the soil. Salt accumulation must be controlled by adequate rainfall or pre-plant leaching.

Understanding nitrogen in soils - extension.umn.edu

Unlike the previously described biological transformations, loss of nitrate by leaching is a physical event. Leaching is the loss of soluble NO 3--N as it moves with soil water, generally excess water, below the root zone. Nitrate-N that moves below the root zone has the potential to enter groundwater or surface water through tile drainage systems.
