The paper presents the results of chemical analysis of the soil samples collected in the spring of 1997 from the arable layer during a field experiment carried out since 1980. In terms of manure doses of up to 40 t per ha, no significant growth of the content of the investigated forms of elements was observed in the arable horizon. The two highest doses of manure (60 and 80 t per ha and also two highest doses of nitrogen (80 and 120 kg of per ha) caused an increase in the amount of zinc and copper in the soil
