  2. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Soil acidification is the buildup of hydrogen ... Agriculture managements approaches such as monoculture and chemical fertilization often leads to soil problems such ...

  3. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    Global variation in soil pH. Red = acidic soil. Yellow = neutral soil. Blue = alkaline soil. Black = no data. Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics.

  4. 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 ...

  5. Edaphology - Wikipedia

    en.wikipedia.org/wiki/Edaphology

    Agricultural soil science is the application of soil chemistry, physics, and biology dealing with the production of crops. In terms of soil chemistry, it places particular emphasis on plant nutrients of importance to farming and horticulture, especially with regard to soil fertility and fertilizer components.

  6. Liming (soil) - Wikipedia

    en.wikipedia.org/wiki/Liming_(soil)

    Prepared agricultural lime staged near a field in the UK. Liming is the application of calcium- (Ca) and magnesium (Mg)-rich materials in various forms, including marl, chalk, limestone, burnt lime or hydrated lime to soil. [1] In acid soils, these materials react as a base and neutralize soil acidity.

  7. Agricultural lime - Wikipedia

    en.wikipedia.org/wiki/Agricultural_lime

    Some effects of agricultural lime on soil are: it increases the pH of acidic soil, reducing soil acidity and increasing alkalinity [1] it provides a source of calcium for plants; it improves water penetration for acidic soils; it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils. [2]

  8. Freshwater acidification - Wikipedia

    en.wikipedia.org/wiki/Freshwater_acidification

    Agricultural runoff is a major source of nitrogen and phosphorus, which contribute to freshwater acidification. Implementing best management practices (BMPs) in agriculture, such as reducing the use of chemical fertilizers, improving manure management, and adopting precision agriculture techniques, can significantly reduce nutrient runoff into ...

  9. Soil test - Wikipedia

    en.wikipedia.org/wiki/Soil_test

    In agriculture, a soil test commonly refers to the analysis of a soil sample to determine nutrient content, composition, and other characteristics such as the acidity or pH level. A soil test can determine fertility, or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility ...
