Producing 1 kg (2.2 lb) of beef requires an average of 25 kg (55 lb) of crop. [19] The production of all this food also results in more and more agricultural waste. In large quantities, agricultural waste can have a negative impact on the environment and habitat, for example through greenhouse gas emissions , the creation of unpleasant odours ...
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 ...
An example of an ecosystem service is pollination, here by a honey bee on avocado crop. Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood ...
Each crop has an optimum range of storage temperature and humidity. Also, certain crops cannot be effectively stored together, as unwanted chemical interactions can result. Various methods of high-speed cooling, and sophisticated refrigerated and atmosphere-controlled environments, are employed to prolong freshness, particularly in large-scale ...
Many crops are of interest for their ability to provide high yields of biomass. Some can be harvested multiple times each year. These include poplar trees and Miscanthus giganteus. The premier energy crop is sugarcane, which is a source of the readily fermentable sucrose and the lignocellulosic by-product bagasse.
There was an increase in global production of primary crops by 56% between 2000 and 2022 to 9.6 billion tonnes, which represents a 0.7% compared to 2021. [2] This represents 3.5 billion tonnes more than in 2000. [2] Cereals represented the main group of crops produced in 2022, followed by sugar crops (23%), vegetables (12%) and oil crops (12%).
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]
