Crushed limestone is used to neutralize acidity in soils. Dolomitic lime is a slow release source of both calcium and magnesium, which improves microbial activity. Lime also helps plants use phosphorous more efficiently, which encourages root growth.
The calcium in lime aids in plant cell wall formation and structure and helps regulate nutrient uptake through the roots and movement throughout the plant. Magnesium is another essential mineral that helps in the formation of amino acids, vitamins, sugars, oils, and fats. It also encourages early growth and winter hardiness.
