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 ]
Cover crops then need to be killed so that the newly planted crops can get enough light, water, nutrients, etc. [37] [38] This can be done by rollers, crimpers, choppers and other ways. [39] [40] The residue is then planted through, and left as a mulch. Cover crops typically must be crimped when they enter the flowering stage. [41]
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.
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance (i.e. no-till farming), maintenance of a permanent soil cover, and diversification of plant species.
This category includes crop species as well as agricultural techniques related to crop farming. ... Crop diversity; Crop insurance; Crop residue; Crop rotation ...
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 ...
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.
