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.
In soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. [1] There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water.
Intensive tillage [note 1] leaves less than 15% crop residue cover or less than 500 pounds per acre (560 kg/ha) of small grain residue. This type of tillage is often referred to as conventional tillage , but as conservational tillage is now more widely used than intensive tillage (in the United States), [ 6 ] [ 7 ] it is often not appropriate ...
(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 ...
Crop genetic diversity is one method that is used to reduce the risks associated with monoculture crops, which can be susceptible to a changing climate. [138] This form of biodiversity causes crops to be more resilient, increasing food security and enhancing the productivity of the field on a long-term scale. [ 138 ]
Domesticated plants Crops drying in a home in Punjab, Pakistan. 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.
