Agricultural use may change soil. These changes may be observed by examining certain soil properties. In numerous cases of agricultural use, soil compaction may be observed at the depth of 25-35 cm. After many years of use, this may lead to the creation of a plough sole. On arable grounds, which are generally fertilized by minerals, a decrease in organic matter content and soil acidification are frequently observed. Each human activity leads to changes in the natural environment. In the case of agricultural use, the greatest changes take place in soil. Mechanization in agriculture and the wish to produce ever-greater amounts of crops influence changes in some soil properties. In a short time, changes in soil reaction, organic matter content or creation of a plough sole at the depth of 25-35 cm may observed.

The aim of the study was the documentation of benthofauna from the Pichna Szadkowicka River flowing through the Wojsławice forest complex in the municipality of Szadek. The study was conducted in July 2013 at eight study sites. Among the collected material, many groups of invertebrates were distinguished, Gammaridae were dominant in the benthic community, Chironomidae, (Diptera) and representatives of the Mollusca (Sphaeridae) were subdominants. Invertebrates were most abundant among macrophytes (Glyceria fluitans) on the sandy bottom with a small fraction of fine particles of organic matter; there was no presence of animals in the stream headwaters area.
