  2. Agricultural wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Agricultural_wastewater...

    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

  3. Agricultural waste - Wikipedia

    en.wikipedia.org/wiki/Agricultural_waste

    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.

  4. Postharvest - Wikipedia

    en.wikipedia.org/wiki/Postharvest

    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 ...

  5. Crop residue - Wikipedia

    en.wikipedia.org/wiki/Crop_residue

    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 ...

  6. Agricultural biotechnology - Wikipedia

    en.wikipedia.org/wiki/Agricultural_biotechnology

    Farmers have manipulated plants and animals through selective breeding for decades of thousands of years in order to create desired traits. In the 20th century, a surge in technology resulted in an increase in agricultural biotechnology through the selection of traits like the increased yield, pest resistance, drought resistance, and herbicide resistance.

  7. Second-generation biofuels - Wikipedia

    en.wikipedia.org/wiki/Second-generation_biofuels

    Second-generation biofuels are made from different feedstocks and therefore may require different technology to extract useful energy from them. Second generation feedstocks include lignocellulosic biomass or woody crops, agricultural residues or waste, as well as dedicated non-food energy crops grown on marginal land unsuitable for food ...

  8. Waste treatment technologies - Wikipedia

    en.wikipedia.org/wiki/Waste_treatment_technologies

    Microbial remediation of xenobiotics has shown to be effective and the low-cost technology, but it still has several limitations. Consequently, the genetic engineering approaches are used to create the new strain of microbes (Genetically engineered microorganisms, GEMS) which have better catabolic potential than the wild type species for ...

  9. Stubble burning - Wikipedia

    en.wikipedia.org/wiki/Stubble_burning

    Agriculture residues can have other uses, such as in particle board [8] and biofuel, [9] though these uses can still cause problems like erosion and nutrient loss. Spraying an enzyme, which decomposes the stubble into useful fertiliser, improves the soil, avoids air pollution and prevents carbon dioxide emissions.
