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.
In pedology, leaching is the removal of soluble materials from one zone in soil to another via water movement in the profile. [1] It is a mechanism of soil formation distinct from the soil forming process of eluviation , which is the loss of mineral and organic colloids .
In agriculture, a catch crop is a fast-growing crop that is grown between successive plantings of a main crop. [1] It is a specific type of cover crop that is grown between two main crops. [ 2 ] This crop is utilized as a way to reduce nitrogen leaching but it also promotes environmental benefits such as fortifying soil structure, retention of ...
When the plants use the water, the salts are left behind in the soil and eventually begin to accumulate. This water in excess of plant needs is called the leaching fraction. Salination from irrigation water is also greatly increased by poor drainage and use of saline water for irrigating agricultural crops.
Leaching is the loss or extraction of certain materials from a carrier into a liquid (usually, but not always a solvent), and may refer to: Leaching (agriculture) , the loss of water-soluble plant nutrients from the soil; or applying a small amount of excess irrigation to avoid soil salinity
A major grower said this week it was abandoning its citrus growing operations, reflecting the headwinds Florida's signature crops are facing following a series of hurricanes and tree diseases.
Leaching is most likely to happen if using a water-soluble pesticide, when the soil tends to be sandy in texture; if excessive watering occurs just after pesticide application; if the adsorption ability of the pesticide to the soil is low. Leaching may not only originate from treated fields, but also from pesticide mixing areas, pesticide ...
Some Democrats are dismissing the forthcoming DOGE push to cut wasteful government spending. Others in the party aren't totally writing off what Elon Musk and Vivek Ramaswamy are selling.
