Summary The following properties were measured on 22 soil samples from seven sites in the south east of England: total CaCO 3 , active CaCO 3 apparent solubility product, particle size distribution of the CaCO 3 , and pH. Active CaCO 3 was between one quarter and one half of the total for all sites except one. Apparent solubility products varied for each parent material, and increased with depth in each profile and ranged from 0.93 to 4.87 × 10 −9 . Soil pH was directly related to apparent solubility product. Active CaCO 3 was closely related to the surface area. pH measured in 0.01 M CaCl 2 was the best index of yield of cauliflower, tomato, sweet white lupin and bitter blue lupin, with chlorotic symptoms increasing and yield decreasing as pH increased. The apparent solubility product of the soil carbonates and pH measured in water were also closely correlated with yield. Total and active CaCO 3 were only related to yield above limits of 20 and 10 per cent respectively and even then were poor indices of yield.
