Four sites of the St. Bernard loam soil type, subjected to differing intensities of cultivation, were investigated for total, organic, adsorbed and exchangeable phosphorus, and anion exchange capacity, as well as the number of samples required for effective sampling. Results indicated that organic phosphorus content decreased with increasing number of years under cultivation. The effect of the different management systems on total, adsorbed and exchangeable phosphorus, and anion exchange capacity was also discussed.
