Liming is used to correct soil's

Liming is a process of adding a substance called lime to soil in order to correct its acidity level. Soil acidity can be a problem for plant growth because it can prevent plants from accessing important nutrients. Lime, which is made from ground limestone, can neutralize the acidity of soil by reacting with the acid present in the soil. Liming can also increase the soil's cation exchange capacity, which is a measure of how well the soil can hold onto positively charged nutrients like calcium, magnesium, and potassium. This is important because these nutrients are essential for plant growth. Liming does not directly affect soil porosity, which refers to the amount of space between soil particles. However, it can indirectly improve soil structure by promoting the growth of beneficial microorganisms that help to create pores and improve soil health.
