Reusing agricultural waste is in line with the desired circular economy. In today's economy, primary raw materials are mostly used. [30] Agricultural waste, on the other hand, is a secondary raw material. They are residual (waste) streams from an existing industry that can serve as raw materials for new applications.
These chemicals may also enter runoff from crop residues, irrigation water, wildlife, and atmospheric deposition. [3]: p. 2–9 Farmers can develop and implement nutrient management plans to mitigate impacts on water quality by: mapping and documenting fields, crop types, soil types, water bodies; developing realistic crop yield projections
Agricultural engineering, also known as agricultural and biosystems engineering, is the field of study and application of engineering science and designs principles for agriculture purposes, combining the various disciplines of mechanical, civil, electrical, food science, environmental, software, and chemical engineering to improve the efficiency of farms and agribusiness enterprises [1] as ...
Crop residues are waste materials generated by agriculture. The two types are: Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves and seed pods. Good management of field residues can increase efficiency of irrigation and control of ...
Genetic engineering can produce crops with a higher concentration of vitamins. For example, golden rice contains three genes that allow plants to produce compounds that are converted to vitamin A in the human body. This nutritionally improved rice is designed to combat the world's leading cause of blindness—vitamin A deficiency.
The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...

Each crop has an optimum range of storage temperature and humidity. Also, certain crops cannot be effectively stored together, as unwanted chemical interactions can result. Various methods of high-speed cooling, and sophisticated refrigerated and atmosphere-controlled environments, are employed to prolong freshness, particularly in large-scale ...
