Sažetak
During 2020 the influence of the cultivation of corn (Zea mays L.), soybean (Glycine max. L., ) and oats (Avena sativa L.) in crop rotation on the content of mobile aluminum, soil reaction and electrical conductivity (EC) was investigated at the experimental farm of the Križevci College of Agriculture. The research was conducted on molic "gleysol" on a plot of one hectare. During the vegetation, average soil samples were taken on three occasions at different phenological stages along the root system of plants. The following soil characteristics were determined from soil samples in the laboratory: mobile aluminum content, pH value in water and 1 MKCl, and electrical conductivity of the soil (EC). Statistically justified lower values of soil reaction measured in water and 1 MKCl up to 30 cm depth were found in black fallow compared to other investigated variants. The following order was determined for the measured values of soil reaction measured in 1 MKCl by variants up to 30 cm of soil depth: black fallow < oats < maize < soybean. It follows from the above that the cultivated crops did not condition the acidification of the soil. The order of mobile aluminum content according to the variants up to 30 cm of soil depth is as follows: black fallow > oats > corn > soybean. The highest value of soil electrical conductivity up to 30 cm of soil depth was in soybean cultivation. The following order of measured values of electrical conductivity according to variants up to 30 cm of soil depth was determined: oats < maize < black fallow < soybean. Possible higher water infiltration in the variants where the crops were grown certainly affected the concentration of the aqueous solution and the measured values of the investigated soil characteristics, so due to wetter conditions, higher soil pH values were measured in the variants with crops.
