摘要

A pot experiment was conducted during 1999-2001 in Poland to determine the influence of different soil amendments on the yield and nutrient status of maize, rape, sunflower and oat, and some soil properties (pH, hydrolytic acidity and organic carbon content). Treatments comprised of mineral treatments with farmyard manure, pig slurry and liquid organomineral fertilizer, and an unfertilized control. Mineral fertilizer and liquid organomineral fertilizer application better affected crop yield in comparison with organic treatments in the first year of the experiment, whereas in the subsequent two years a consecutive effect of organic fertilizers was observed. According to the hypotheses, the biggest nitrogen concentrations were found in crops receiving mineral treatment and organomineral fertilizer. Phosphorus content depended on crop species and the applied fertilizer. Potassium and magnesium contents immediately after treatment were highest in the treatment with farmyard manure and slurry. In the subsequent years, no visible tendency in both element contents was noticed. Among the cultivated crops, rape revealed the biggest amounts of cadmium in the aboveground parts. Lead concentrations in the aboveground parts of the cultivated crop did not reveal any diversification among the objects. Copper accumulated mainly in the crop root systems, except rape, whereas zinc concentration depended on the plant species and applied fertilizer. The treatment caused a decrease in soil pH and an increase in hydrolytic acidity value. Mineral and organomineral fertilizer application caused a pronounced decline in organic carbon content in the soil, whereas farmyard manure increased it. Similar dependencies were found for the total nitrogen concentrations. The applied treatments increased the contents of mobile forms of cadmium, lead and zinc but had no significant effect on the changes of mobile copper form contents.
