B. Sarapatka et M. Krskova, INTERACTIONS BETWEEN PHOSPHATASE-ACTIVITY AND SOIL CHARACTERISTICS FROM SOME LOCATIONS IN THE CZECH-REPUBLIC, Rostlinna vyroba, 43(9), 1997, pp. 415-419
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.
