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 ...
Also called the residue yield or straw/grain ratio, the equation takes the mass of residue divided by the mass of crop produced, and the result is dimensionless. [1] The RPR can be used to project costs and benefits of bio-energy projects, and is crucial in determining financial sustainability. The RPR is particularly important for estimating ...
The four most commonly grown agricultural crops worldwide are sugarcane, maize, cereals and rice. [3] The total weight of all these crops is more than 16,500 billion kilograms per year. [ 4 ] Since 80% of this consists of agricultural waste, many tens of thousands of billions of kilograms of agricultural waste remain worldwide. [ 5 ]
Planting cover crops that keep the soil anchored and covered in off-seasons so that the soil is not eroded by wind and rain. Crop rotations [18] for row crops alternate high-residue crops with lower-residue crops to increase the amount of plant material left on the surface of the soil during the year to protect the soil from erosion.
The term “pesticide residue” includes residues from unknown or unavoidable sources (e.g. environmental) as well as known uses of the chemical. The definition of a residue for compliance with maximum residue limits (MRLs) is that combination of the pesticide and its metabolites, derivatives and related compounds to which the MRL applies. [4]

The maximum residue limit (also maximum residue level, MRL) is the maximum amount of pesticide residue that is expected to remain on food products when a pesticide is used according to label directions, that will not be a concern to human health.
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; Residue (chemistry), materials remaining after a physical separation process, or by-products of a chemical reaction
