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 ...
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 Federal Bureau of Statistics provisionally valued major crop yields at Rs.504,868 million in 2005 thus registering 55%+ growth since 2000 [16] while minor crop yields were valued at Rs.184,707 million in 2005 thus registering 41%+ growth since 2000. The exports related to the agriculture sector in 2009–10 are Rs 288.18 billion including ...
A crop is a plant that can be grown and harvested extensively for profit or subsistence. [1] In other words, a crop is a plant or plant product that is grown for a specific purpose such as food, fibre, or fuel. When plants of the same species are cultivated in rows or other systematic arrangements, it is called crop field or crop cultivation.
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
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]
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 ...
