eliminating magnesium in dolomite for sale in chile

Dolomite also adds calcium and helps to improve soil structure and increases the availability of some trace elements. Applying calcium in isolation can induce a magnesium deficiency (Ca:Mg ratio). Even though calcium is a very important nutrient in the soil, in isolation it can also reduce the availability of potash and phosphate, as well as manganese, molybdenum, boron, zinc and iron.
