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.
Biological substances can experience leaching themselves, [2] as well as be used for leaching as part of the solvent substance to recover heavy metals. [6] Many plants experience leaching of phenolics, carbohydrates, and amino acids, and can experience as much as 30% mass loss from leaching, [5] just from sources of water such as rain, dew, mist, and fog.

Blanch green beans by placing in boiling water for 1 minute, drain and place in an ice water bath. In a sauté pan, add the oil over medium high and cook the shallots for 30 to 45 seconds. Add the ...
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
Parboiling (or leaching) is the partial or semi boiling of food as the first step in cooking. The word is from the Old French parbouillir, 'to boil thoroughly' but by mistaken association with "part", it has acquired its current meaning. [1] [2] The word is often used when referring to parboiled rice.
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.
Catch crops help protect soil against water erosion through its residue which increases soil roughness. The residue serves as a soil surface protection from splash effects as well contributes to lowering the surface runoff. Certain catch crop species are also able to create biopores by decaying roots which create flow paths in the soil causing ...
Certain chemicals are leaching from food packaging into food and have been detected in human bodies — and a new study sheds light on just how much. Whether all of these chemicals pose ...
