Crop residues are waste materials generated by agriculture. The two types are: Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves and seed pods. Good management of field residues can increase efficiency of irrigation and control of ...
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 ...
(pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...
Crop residue, such as corncob, and other residues from the food processing industry, such as residues from biorefineries, have high potential for use in further processes, such as producing biofuel, bioplastics, and other biomaterials for industrial processes. [11] [12]
In agriculture, windrow composting is the production of compost by piling organic matter or biodegradable waste, such as animal manure and crop residues, in long rows – windrow. As the process is aerobic, it is also known as Open Windrow Composting (OWC) or Open Air Windrow Composting (OAWC). [54]
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.
Increasing the angle of disks causes residues to be buried more deeply. Increasing their concavity makes them more aggressive. Chisel plows can have spikes or sweeps. Spikes are more aggressive. Percentage residue is used to compare tillage systems because the amount of crop residue affects the soil loss due to erosion. [22] [24]
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
