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.

The first step in blanching green beans Broccoli being shocked in cold water to complete the blanching. Blanching is a cooking process in which a food, usually a vegetable or fruit, is scalded in boiling water, removed after a brief timed interval, and finally plunged into iced water or placed under cold running water (known as shocking or refreshing) to halt the cooking process.
Leafy vegetables lose water quickly because they have a thin skin with many pores. Potatoes, on the other hand, have a thick skin with few pores. But whatever the product, to extend shelf or storage life the rate of water loss must be minimal. The most significant factor is the ratio of the surface area of the fruit or vegetable to its volume.
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.
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 ...
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
Shocking broccoli in cold water. Shocking is a cooking process wherein the food substance, usually a vegetable or fruit, is plunged into iced water or placed under cold running water to halt the cooking process. [1] This process usually keeps the colour, taste and texture of a fruit or vegetable. [2]
