- Promotes strong healthy plant growth.- Enhances fertiliser response.- Improves soil structure and humus formation.- Aids in plant strength.- Adds essential calcium and magnesium.- Corrects acidity.Calcium is a very important element in all plants. It helps to strengthen plant cell walls. Dolomite helps to increase soil pH increasing the availability of soil nutrients. However, do not use on acid loving plants such as camellias, azaleas and rhododendrons.Calcium deficiency: can often be noticed in the younger leaves (higher leaves on the plant or at the tip of the branch). General symptom include stunting of plant growth, paling of young leaves, even blackening of leaf tips and margins. Petals tend to appear water-soaked, due to loss of cell structure. These symptoms may occur due to insufficient lime or dolomite in the soil, or excessive applications of potassium or ammonium based fertilisers.Magnesium deficiency: can often be noticed in older leaves (lower leaves on the plant). General symptoms include a bronze-yellow discolouration along the leaf margins towards the tip. These symptoms may occur due to insufficient magnesium in the soil (adding lime rather than dolomite) or excessive applications of potassium or sodium.
