INTERACTIONS BETWEEN PHOSPHATASE-ACTIVITY AND SOIL CHARACTERISTICS FROM SOME LOCATIONS IN THE CZECH-REPUBLIC

Soil phosphatases play a major role in the mineralization processes of organic phosphorus substrates. Their activity can be influenced by nu merous factors and soil properties play a key role among them. This re search adds to the growing knowledge on soil phosphatases and their in teractions with the specific soil characteristics of nine sites in the Czech Republic with common soil types. The results show correlations and linear equations between phosphatase activity and some soil charac teristics. Positive correlations were found between enzymatic activity and organic carbon, and with nitrogen, and between acid phosphatase a ctivity and total phosphorus. Negative correlations were with the qual ity of humus (humic : fulvic acids ratio) and available phosphorus, an d between acid phosphatase activity and clay content and pH.
