liming and its uses in agriculture



Liming

Liming refers to the process whereby calcium or magnesium containing compounds are added to the soil to reduce soil acidity.

Some common liming materials are:

(i) Limestone – CaCO3
(ii) Quicklime – CaO
(iii) Slaked lime – Ca (OH)2
(iv) Basic slag – Ca(OHSiO3)2
(v) Dolomite or calcite – Caco3MgCO3
(vi) Calcium bicarbonate – Ca(HCO3)2
(vii) Gypsum – CaSO3 2H30
(viii) Woodash – Ca(PO4)2Si)4
Generally, most crops perform well between pH range of 6 – 8.


Uses of Lime in Agriculture

Application of lime helps to maintain soil fertility in the following ways
(i) It helps to reduce or neutralize soil acidity.
(ii) Lime application helps to increase the activities of the soil living organisms
(iii) Liming makes nutrients like calcium and phosphorus more readily available for tissue development.
(iv) Liming also improves the soil structure.
(v) It also increases the availability of phosphates and molybdenumions.
(vi) Lime increases the rate of water percolation in clay soil
(vii) It reduces the toxicity of dissolved copper and manganese in the soil
(viii) It serves as additional sources of calcium for bone development in fish
(ix) It reduces turbidity in fish ponds through flocculation property.
