Lime is very helpful in maintaining the water content in the soil

|
|
Lime decreases the acidity of soil
|
|
|
Lime decreases the basicity of soil
|
|
|
High concentration of lime is necessary for the plant growth
|
Detailed explanation-1: -Decaying plant matter raises the acidic levels. Lime helps to reduce the acid content, changing pH levels for optimum plant growth. There are certain times when a farmer/gardener might not do this, but it usually only occurs when a plant needs a higher or lower pH balance.
Detailed explanation-2: -Soil acidity can be corrected easily by liming the soil, or adding basic materials to neutralize the acid present. The most commonly used liming material is agricultural limestone, the most economical and relatively easy to manage source. The limestone is not very water-soluble, making it easy to handle.
Detailed explanation-3: -Adding lime (Figure 1) increases soil pH (reduces acidity), adds calcium (Ca) and/or magnesium (Mg), and reduces the solubility of Al and Mn in the soil.
