Liming (soil) - Wikipedia
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 .
Soil Acidity and Liming: Basic Information for Farmers and …

Soil Acidity and Liming for Agricultural Soils SoilFacts
2 天之前 · Nearly all North Carolina soils are naturally acidic and need lime, which neutralizes the acidity, for optimum growth of crops, forages, turf, trees, and many ornamentals. Even though most of these soils have been limed in the past, periodic …
Soil pH is an excellent chemical indicator of soil quality. Farmers can improve the soil quality of acid soils by liming to adjust pH to the levels needed by the crop to be grown. Benefits of liming include increased nutrient availability, improved soil structure, and increased rates of infiltration. United States Department of Agriculture.
Soil acidification and the importance of liming agricultural soils …
2016年6月24日 · ‘Liming’ also reduces N 2 O emissions, but this is more than offset by CO 2 emissions from the lime as it neutralizes acidity.
Basic Principles of Liming. John Peters UW Soil Science Department. Soil pH affects many chemical and physical reactions in soil. Availability of most essential elements. Activity of microorganisms.

Liming, Effects on Soil Properties | SpringerLink
2014年1月1日 · Liming increases soil pH and removes toxicities of aluminum and manganese associated with acidity, and amends soil physical, physicochemical, chemical, and biological properties (Brown et al., 1959; McLean, 1971; Edmeades et al., 1981; Costa et al., 2004). Calcium cations coagulate soil organic and mineral colloids and can improve soil ...
Liming - an overview | ScienceDirect Topics
2011年3月1日 · Liming is a common agricultural practice worldwide, used for increasing productivity in acid agricultural soils. Liming reduces Al saturation and toxicity and/or increases pH up to values where the availability of nutrients is higher.
Liming impacts on soils, crops and biodiversity in the UK: A review
2018年1月1日 · Liming impacts on soils are positive such as increased nutrients and biota. •. Liming crops and grassland is beneficial to yield and quality and for grazing stock. •.

Liming effects on soil pH and crop yield depend on lime
2018年8月23日 · This study examined the effects of liming rate, lime application method, and liming material type on various soil chemical properties and crop yield based on data collected from 175 published studies worldwide since 1980. The most important variables that drive changes in soil pH and crop yield were liming rate and crop species, respectively.
