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 ]
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 ...
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.
In the United States, it is often used as an intercrop. Thus, proso millet can help to avoid a summer fallow, and continuous crop rotation can be achieved. Its superficial root system and its resistance to atrazine residue make proso millet a good intercrop between two water- and pesticide-demanding crops. The stubbles of the last crop, by ...
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 ...
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.
Rabi crops or the rabi harvest, also known as winter crops, are agricultural crops that are sown in winter and harvested in the spring in India, Pakistan, and Bangladesh. [1] Complementary to the rabi crop is the kharif crop , which is grown after the rabi and zaid crops are harvested one after another respectively.
