The role of catalytic activity of fungal phosphatases in the improvement of the phosphorus nutrition cannot be reliably predicted without taking into account the factors which influence their behaviour in the soil. The objective of this thesis was to study various factors which could influence the effectiveness of ectomycorrhizal fungal phosphatases in soils. Adsorption and the activity in the adsorbed state of phosphatases produced by Suillus collinitus and Hebeloma cylindrosporum were studied in contact with several fractions of various tropical soils. The persistence of the activity of these enzymes immobilized on the soils was also studied. These phosphatases showed a diversity of affinity for soil colloids, due to their origin and thei...
