  2. Soil conservation - Wikipedia

    en.wikipedia.org/wiki/Soil_conservation

    The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil ...

  3. Soil management - Wikipedia

    en.wikipedia.org/wiki/Soil_management

    Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...

  4. Soil health - Wikipedia

    en.wikipedia.org/wiki/Soil_health

    Fig. Concept of Soil Health Gap. The importance of soil for global food security, agro-ecosystem, environment, and human life has exponentially shifted the research trends toward soil health. However, the lack of a site/region-specific benchmark has limited the research toward understanding the effect of different agronomic managements on soil ...

  5. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.

  6. 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 ...

  7. Soil regeneration - Wikipedia

    en.wikipedia.org/wiki/Soil_regeneration

    Soil degradation means that soil quality has diminished, which causes ecosystem functions to decline. [1] One third of the globe's land has degraded soil; [1] especially the tropics and subtropics with around 500 million hectares. [1] Soil degradation occurs due to physical, chemical, and biological forces. [5] These forces can be natural and ...

  8. Soil conditioner - Wikipedia

    en.wikipedia.org/wiki/Soil_conditioner

    The soil conditioning technology was presented at a symposium on "Improvement of Soil Structure" held in Philadelphia, Pennsylvania on December 29, 1951. The technology was strongly documented and was published in the June 1952 issue of the journal Soil Science , volume 73, June 1952 that was dedicated to polymeric soil conditioners.

  9. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    After studies of soil improvement commenced, other researchers began to study soil genesis and, as a result, soil types and classifications. In 1860, while in Mississippi, Eugene W. Hilgard (1833–1916) studied the relationship between rock material, climate, vegetation, and the type of soils that were developed.
