OBJECTIVE FORESTRY

Detailed explanation-1: -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.

Detailed explanation-2: -Drainage of soil water can lead to the loss of nutrients when those nutrients are dissolved in the soil solution and move beyond the root zone. This movement of nutrients from the root zone to the soil below is called leaching.

Detailed explanation-3: -Currently, leaching primarily describes the process of water carrying soluble substances or small particles through soil or rock. Although this process seems trivial, leaching is one of the key processes of the Critical Zone, controlling the rate and direction in which compounds move.

Detailed explanation-4: -Within the chemical industry, the process of leaching is commonly referred to as extraction.

Detailed explanation-5: -Introduction. Leaching is the process of pesticide movement with water flowing down in the soil profile. Drainage, in turn, covers the case when this water flows into a subsurface drainage network connected to surface water, while leaching covers the case when it flows into groundwater.
