The residue can be ploughed directly into the ground, or burned first. In contrast, no-till, strip-till or reduced-till agriculture practices are carried out to maximize crop residue cover. Simple line-transect measurements can be used to estimate residue coverage. [1] Process residues are materials left after the crop is processed into a ...
Burning of rice residues in southeast Punjab, India, prior to wheat season. Agricultural waste consists mainly of cellulose, hemicellulose and lignin. [7] Agricultural waste is poorly digestible and in unprocessed form not widely suitable as animal feed. [8] Sometimes, agricultural waste is burnt, either as biomass in power plants or simply on ...
Field residues may be maintained as soil cover, burned, or ploughed into the soil as green manure; process residues are often used as animal fodder or soil amendments. crop rotation The practice of cultivating a series of different crops in the same space over the course of multiple growing seasons , often in a specific sequence that repeats in ...
Crop residue, materials left after agricultural processes; Pesticide residue, refers to the pesticides that may remain on or in food after they are applied to food crops; Petroleum residue, the heavier fractions of crude oil that fail to vaporize in an oil refinery
Waste valorization, beneficial reuse, beneficial use, value recovery or waste reclamation [1] is the process of waste products or residues from an economic process being valorized (given economic value), by reuse or recycling in order to create economically useful materials.
Crop residues: stover, copra, straw, chaff, sugar beet waste; Fish meal; Freshly cut grass and other forage plants; Grass or lawn clipping waste [4] Green maize; Green sorghum; Horse gram; Leaves from certain species of trees [5] Meat and bone meal (now illegal in cattle and sheep feeds in many areas due to risk of BSE) Molasses; Native green grass
Corn stover, due to the relative close proximity of the corn grain produced for ethanol production, "is by far the most abundant crop residue readily available today." [8] The free accessibility to corn stover makes it a prime candidate for biomass ethanol production.
Pesticide residue refers to the pesticides that may remain on or in food, after they are applied to food crops. [1] The maximum allowable levels of these residues in foods are stipulated by regulatory bodies in many countries. Regulations such as pre-harvest intervals also prevent harvest of crop or livestock products if recently treated in ...
