  2. Soil conditioner - Wikipedia

    en.wikipedia.org/wiki/Soil_conditioner

    Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well. The addition of organic material for instance can greatly improve the water retention abilities of sandy soils and they can be added to adjust the pH of the soil to meet the needs of specific plants or to make highly acidic or ...

  3. Soil quality - Wikipedia

    en.wikipedia.org/wiki/Soil_quality

    Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...

  4. Soil regeneration - Wikipedia

    en.wikipedia.org/wiki/Soil_regeneration

    Soil is composed of organic matter (decomposing plants, animals, and microbes), biomass (living plants, animals, and microbes), water, air, minerals (sand, silt, and clay), and nutrients (nitrogen, carbon, phosphorus). [4] For optimal plant growth, a proper carbon to nitrogen ratio of 20–30:1 must be maintained. [3]

  5. Agricultural lime - Wikipedia

    en.wikipedia.org/wiki/Agricultural_lime

    Lime can improve crop yield and the root system of plants and grass where soils are acidic. It does this by making the soil more basic, allowing the plants to absorb more nutrients. Lime is not a fertilizer but can be used in combination with fertilizers. [3] [4] Soils become acidic in several ways.

  6. Leaching (agriculture) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(agriculture)

    As nitrogen naturally cycles through the air, water and soil it undergoes various chemical and biological transformations. Nitrogen promotes plant growth. Livestock then eat the crops producing manure, which is returned to the soil, adding organic and mineral forms of nitrogen. The cycle is complete when the next crop uses the amended soil. [1]

  7. Soil health - Wikipedia

    en.wikipedia.org/wiki/Soil_health

    Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components (living and non-living) that belong together, as in microbiota, plants and animals.

  8. Phytoremediation - Wikipedia

    en.wikipedia.org/wiki/Phytoremediation

    Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]

  9. Effective microorganism - Wikipedia

    en.wikipedia.org/wiki/Effective_microorganism

    "Hence 'Effective Microorganisms' will not be able to improve yields and soil quality in mid term (3 years) in organic arable farming." [4] [15] In a study (2010), Factura et al. collected human fecal matter in airtight buckets (Bokashi-dry toilet) over several weeks, adding a mix of biochar, lime and soil after each deposit of fecal matter ...
