In the static experiment that has been carried out since 1979, the organic fertilization of rye straw or of manure plus rye straw with 4 levels of nitrogen fertilization were applied. The following rotation - potato, winter rye, winter rye was used. In this work, the estimation of the influence of both of the experiment factors on some podsolic soil properties was made.
