Answer:
What is soil nutrient leaching?
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Leaching may also refer to the practice of applying a small amount of excess irrigation where the water has a high salt content to avoid salts from building up in the soil (salinity control).
Explanation:
Furthermore, how does soil leaching occur? Leaching occurs when the air spaces in soil become filled with water and gravity begins to move water downward. The percolating water carries any soluble salts that are present in the soil and is not specific for nitrate.
Similarly, you may ask, what is meant by leaching process?
Leaching is a process of extracting a substance from a solid material that is dissolved in a liquid. This process is commonly referred to as extraction, particularly in the chemical industry. Three basic steps are involved in the leaching process: contact, separation, and extraction.
What are the effects of leaching?
Leaching removes vital nutrients and micronutrients, such as water-soluble boron, from the soil, causing potential deficiencies in crops. For example, when crops suffer from boron deficiency, they exhibit visual symptoms including: Misshapen, thick, brittle, small leaves. Short stems and a "shrunken" appearance.
