Calcium to Magnesium Ratio
There has been a lot of interest in ideal soil
Remedial action includes boosting calcium levels through the addition of gypsum or lime. If the pH of the soil is neutral or alkaline, don't use lime as this will increase the pH further. As such, gypsum is probably the best material to use for boosting calcium levels gently. If soil is very calcium deficient, a specialised calcium fertiliser may be used. If magnesium levels are high and the pH is low, dolomite may seem to be a useful amendment but avoid the temptation because it can actually upset the calcium to magnesium ratio further.
