  2. Leaching (agriculture) - Wikipedia

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

    In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure , crop planting, type and application rates of fertilizers , and other factors are taken into account to avoid excessive nutrient loss.

  3. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

    en.wikipedia.org/wiki/Nutrient_management

    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 ...

  5. Agricultural pollution - Wikipedia

    en.wikipedia.org/wiki/Agricultural_pollution

    Leaching is affected by the soil, the pesticide, and rainfall and irrigation. Leaching is most likely to happen if using a water-soluble pesticide, when the soil tends to be sandy in texture; if excessive watering occurs just after pesticide application; if the adsorption ability of the pesticide to the soil is low.

  6. Nutrient depletion - Wikipedia

    en.wikipedia.org/wiki/Nutrient_depletion

    On the level of a complete ecological niche or ecosystem, nutrient depletion can also come about via the loss of the nutrient substrate (soil loss, wetland loss, etc.). Nutrients are usually the first link in the food chain, thus a loss of nutrients in a habitat will affect nutrient cycling and eventually the entire food chain. [2] [3] Nutrient ...

  8. Potassium cycle - Wikipedia

    en.wikipedia.org/wiki/Potassium_cycle

    The most abundant ion in plant cells is the potassium ion. [2] Plants take up potassium for plant growth and function. A portion of potassium uptake in plants can be attributed to weathering of primary minerals, but plants can also ‘pump’ potassium from deeper soil layers to increase levels of surface K. [2] Potassium stored in plant matter can be returned to the soil during decomposition ...
