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.
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 ]

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 ...
Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport ...
Fertilizers are used to provide crops with additional sources of nutrients, such as nitrogen, phosphorus, and potassium, that promote plant growth and increase crop yields. While they are beneficial for plant growth, they can also disrupt natural nutrient and mineral biogeochemical cycles and pose risks to human and ecological health.
