They are light sandy soils with good drainage and aeration, low cationexchange capacity, low organic carbon and total nitrogen concentrations. The cationexchange capacity was calculated by summing the basic cations and the exchangeable acidity. The cationexchange capacity is very low at less than 15 meq (100 g)-1 of clay. The post-1996 wheat crop samples were also analysed for exchangeable bases (ammonium acetate extraction) and cationexchange capacity (potassium chloride). Irradiation of acids in clays amount of the acid was calculated in order to remain below the cationexchange capacity of the clay. In the present study, soils are already in an advanced stage of weathering with a low cationexchange capacity and base saturation. One noticeable difference in soil quality indicators between the two farms sites was the base saturation ratio of the cationexchange capacity. Furthermore, the counterions are constrained to remain in the unfrozen films by the need to satisfy the cationexchange sites on the soil particle surfaces. The addition of manure imp roves soil waterholding capacity, cationexchange capacity, and soil structure. By contrast, calcium accounted for 65.9-71.2% of the cationexchange capacity at the organic farm site. This is used as a soil conditioner which increases the soil's capacity to hold water and nutrients by increasing capillary forces and cationexchange capacity.
