[QUOTE="Warnesworth, post: 6482494, member: 3357"] Quite correct. If you want to correct acid pH (i.e neutralise the Hydrogen ions on the soil colloid) you need carbonate. The cheapest form being calcitic or dolomitic lime. But if the lime still resembles road grit when spread it isn't going to react and neutralise anything. But high levels of magnesium, potash or sodium can keep the soil pH high but you have no calcium. Calcium is an essential plant mineral and one which a lot of studies show is essential for the uptake of many other minerals, therefore if you are short of calcium you will be depriving your crop of other essential minerals too.
