2. To improve water penetration: When the soil is on the acidic side, adding lime can improve water penetration of the soil. By raising the alkalinity of the soil, water can more easily rehydrate the soil, thereby rehydrating your plants and preventing them from drying out. 3. To make your soil more alkaline: Most vegetables prefer to grow in ...

Lime also supplies soil with two essential plant nutrients: calcium and magnesium. Recent soil test summaries indicate that about 10 percent of Michigan's 7.8 million acres of agricultural land need at least 2.5 tons/acre of lime, for a total of 1.95 million tons of lime needed statewide to neutralize soil acidity.

properties of lime govern its quality: purity (percent calcium carbonate equivalent) and fineness (particle size). These two factors are used to calculate the neu- ... role in lime's effectiveness at neutralizing soil pH. This is because limestone dissolves slowly, so its effective-ness is limited to a small area around each particle.
