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 ...
This replaces the proportion of cellulose fibres from trees, meaning that these trees do not need to be cut down for paper production, but can be left to absorb CO₂ and convert it into oxygen. Made from agricultural waste, this paper and board meets high quality standards and is available as printing paper, among other things. [ 32 ]
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.
Primary tillage such as ploughing tends to produce a rough surface finish, whereas secondary tillage tends to produce a smoother surface finish, such as that required to make a good seedbed for many crops. Harrowing and rototilling often combine primary and secondary tillage into one operation. "Tillage" can also mean the land that is tilled.
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 ...
A ridging plough is used for crops such as potatoes or scallions grown buried in ridges of soil, using a technique called ridging or hilling. A ridging plough has two back-to-back mould boards cutting a deep furrow on each pass with high ridges either side. The same plough may be used to split the ridges to harvest the crop.
Sorghum grown as forage crop.. Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. [1] Historically, the term forage has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage.
(Only major crops) Mango Orchard in Multan, Pakistan Indus River Delta. Agriculture is considered the backbone of Pakistan's economy, which relies heavily on its major crops. [1] Pakistan's principal natural resources are arable land and water. Agriculture accounts for about 18.9% [2] of Pakistan's GDP and employs about 42.3% of the labour ...
