Citrus hystrix, called the kaffir lime, Thai lime [4] or makrut lime, [5] (US: / ˈ m æ k r ə t /, UK: / m ə k ˈ r uː t /) [6] is a citrus fruit native to tropical Southeast Asia. [7] [8] Its fruit and leaves are used in Southeast Asian cuisine, and its essential oil is used in perfumery. [9] Its rind and crushed leaves emit an intense ...
Compare yellow chlorotic leaves with the green non chlorotic leaves at left of this image. Iron (Fe) deficiency is a plant disorder also known as "lime-induced chlorosis". It can be confused with manganese deficiency. If soil iron concentration is high, in spite of this it can become unavailable for absorption if soil pH is higher than 6.5. [1]
Then, using the initial soil pH and the aluminium content, the amount of lime needed to raise the pH to a desired level can be calculated. [68] Amendments other than agricultural lime that can be used to increase the pH of soil include wood ash, industrial calcium oxide , magnesium oxide, basic slag (calcium silicate), and oyster shells.
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.
Tree bumblebee on the small-leaved lime. Tilia cordata, the small-leaved lime or small-leaved linden, is a species of tree in the family Malvaceae, native to much of Europe.. Other common names include little-leaf or littleleaf linden, [2] or traditionally in South East England, pry or pry tree.
Specific nutrient deficiencies (often aggravated by high soil pH) may be corrected by supplemental feedings of iron, in the form of a chelate or sulphate, magnesium or nitrogen compounds in various combinations. If the soil is too acidic, applying lime can raise the pH to the proper range, making more nutrients available to the plant.
The leaves are intermediate between the parents, 6–15 centimetres (2–6 inches) long and 6–12 cm (2–5 in) broad, thinly hairy below with tufts of denser hairs in the leaf vein axils. The flowers are produced in clusters of four to ten in early summer with a leafy yellow-green subtending bract; they are fragrant, and pollinated by bees .
Calcined gypsum is an alternative material in industrial plasters and mortars. Cement, cement kiln dust, fly ash, and lime kiln dust are potential substitutes for some construction uses of lime. Magnesium hydroxide is a substitute for lime in pH control, and magnesium oxide is a substitute for dolomitic lime as a flux in steelmaking. [28]
