Biochemical and chemical indices of soil transformations on goose farms in years 1996-2011

The paper presents characterisation of the eco-chemical condition and potential threats to soils of goose farms on the basis of recent monitoring of a 15-year measuring cycle. It was demonstrated that the observed soil enzymatic inactivation progressing with years of investigations on the examined farms was significantly associated with a very high content of mineral nitrogen and available forms of phosphorus. A distinct tendency towards increased content of heavy metals in soils derived from these farms as well as in their direct neighbourhood observed with the passage of time poses a serious hazard to the environment.
