Description
Summary:In the long term fertilization experiment of Debrecen University, CASE (Debrecen Látókép) the effect of fertilization lasting more than 25 years was examined on the soil microbiological properties. With the increasing doses of the fertilizers applied decreased the pH significantly and increased the hidden acidity, while changed the ratio and occurrence in the soil bacteria and microscopic fungi and also decreased the quantity of microbial groups. These changes show the answer reactions of living organisms; it corresponds to the „resistance stage” of stress effect, and while in case of nitrifying bacteria reaches the „exhaustion stage”.
