Abstract:

A rapidly diminishing number and degradation of water ponds cause many negative effects in the structure of agricultural ecosystems, by limiting surface retention and increasing migration of chemical compounds from the basin. The goal of this research was tofind the influence of anthropopression on the chemical composition of water in field ponds. Analysis of some chemical and physical parameters was carried out on water samples collected once a month from 5 field ponds located in the District of Pyrzyce, Commune of Żabowo, between March and October 2004. The five water ponds differed with respect to thespatial development of their surroundings and their degradation. The concentration of N-NH4, N-NO2 i N-NO3 oraz PO43– were measured according to the Polish Standards.The level of oxygen, temperature and water pH were measured immediately after collectingeach sample of water. The analyzed field ponds were different in respect of the degreeof degradation processes. What was characteristic of the five ponds was a large variationin concentrations of biogenic compounds in water, depending on the formof anthropopression and vegetation in and around the ponds. The high level of PO43– and N-NH4 in water and the succession of water plants prove that ponds 2, 3 and 4 are highly eutrophicated. Due to the extremely high concentration of PO43– in the water, fieldpond 2, located near a former state farm, can be classified as hypertrophic. This pond alsohad the biggest oxygen deficit.
