THE EFFECT OF FERTILIZATION WITH SEWAGE SLUDGE FROM A DAIRY PLANT AND WITH RAPE STRAW ON THE POPULATION NUMBERS OF SELECTED MICROORGANISMS AND RESPIRATION ACTIVITY OF BROWN SOIL

摘要

The research was carried out in a pot experiment. The effect of daily sewage sludge and rape straw on the numbers of bacteria and fungi and on the respiration activity was examined. The pot experiment included three treatments: 1 — control soil, 2 -soil + dairy sewage sludge, ,3 - soil + dairy sewage sludge + rape straw. As a result of laboratory investigations, the addition of sewage sludge from a dairy plant to soil was found to stimulate the total number of bacteria, actinomycetes, and fungi andthe number of cellulolytic bacteria, as well as to contribute to the increase in the respiration activity of soil.
