Dolomite - Soil Conditioner & pH Raiser

Dolomite is a natural calcium magnesium carbonate and one of the easiest ways to sweeten an acidic soil, gently raising its pH while adding two nutrients plants need: calcium and magnesium. It is finely ground so it breaks down steadily in the soil, and it also helps improve soil structure and the uptake of other nutrients. Features High neutralising value (NV 98%), so it corrects soil acidity efficiently Raises the pH of acidic soils (sweetens sour soil) Adds both calcium and magnesium, correcting magnesium deficiency Helps improve soil structure and nutrient availability Finely ground (95% finer than 0.15mm), so it is fast-acting in the soil A 100% natural mineral, Australian sourced Perfect for Correcting acidic soils in garden beds and pots Magnesium-deficient soils where leaves are yellowing Vegetable beds, flower beds and lawns Adding a little to potting mixes, worm farms and compost to counter acidity How to use (a guide only, always adjust to your own soil) Flower and garden beds: around 75 to 150 g per square metre Heavier clay soils: around 150 to 300 g per square metre It is worth doing a pH test first. Dolomite raises pH, so avoid adding it to soils that are already alkaline, as this can lock up nutrients.
