The effect of agrotechnical elements (crop rotation, fertilisation, irrigation) on maize yield and various chemical characteristics of the soil (pHH2O, pHKCl, hydrolytic acidity (y1)) were examined in a long-term experiment (established in 1983) on calcareous Chernozem in the Hajdúság region of Hungary. The yield obtained in 2019 showed the favourable water supply of the crop year and outstanding nutrient utilisation of maize. In the control (non-fertilised) treatments, maize yield was 8 t/ha in monoculture, 11 t/ha in biculture and 12 t/ha in triculture, while the highest yield obtained with the optimum fertiliser treatment increased to 13, 13.5 and 14 t/ha, respectively. In the long-term experiment established 35 years ago, the pH values of the soil greatly decreased in comparison to the initial value. The following ranges were observed in monoculture: 5.57–6.49 (pHH2O), 4.69–5.34 (pHKCl), in biculture: 5.22–6.62 (pHH2O) and 4.36–5.68 (pHKCl), and in triculture: 5.46–6.29 (pHH2O), and 4.56–5.24 (pHKCl). Hydrolytic acidity values (mono y1 = 7.75–14.75, bi y1 = 11.50–23.00, tri y1 = 10.13–18.38) showed strong soil acidity. In the long-term experiment, a moderate (0.512xx, LSD0.01=xx) correlation between fertilisation and yield and a moderate (0.397xx) correlation between crop rotation and yield could be established on Chernozem. A moderately negative (pHH2O = –0.594xx, pHKCl = –0.543xx) correlation was found between the yield and pH values, while a moderately positive (y1 = 0.409xx) correlation was found between the hydrolytic acidity and yield.

We examined the change of the time of water balance of soil in long-term experiment, on chernozem soil, in different croprotation systems (mono-, bi- and triculture). We found the smallest difference between the water deficit of not irrigated and irrigated plots in triculture. We concluded that irrigation impressed favourably on water balance of soil in both of crop-rotation systems. Water deficit has decreased significantly after irrigationin 25. May in mono- and triculture. Irrigation moderated only values of water deficit. Irrigation in 30. June not influenced water balance of soil in both of crop-rotation because of a big drought. Water deficit of soil lessed till harvestperiod because of rainy season at the end of August and in September.

The possibilities to use sapropel for fertilisation have been investigated at the Voke Branch of the Lithuanian Institute of Agriculture since 1984. The experiments were carried out on sandy loam Haplic Luvisols in the crop rotation (maize, barley, clover, winter rye, potatoes, oats) with the application of 50, 100, 150, 200 t/ha rates of dry calcareous sapropel and 30 t/ha of dry manure on the background of mineral fertilisers. Sapropel was applied only to the first crop (maize) in the rotation (in 1984). Manure was applied to the first crop in each crop rotation (in 1984, 1990 and 1996). Summarised results of a long-term experiment showed that by the end of the second (after 12 years) and third (after 18 years) rotation the effect of sapropel on soil chemical properties was positive. Calcareous sapropel reduced soil acidity, increased the amount of exchangeable bases (Ca + Mg). Under the influence of sapropel the contents of organic carbon and total nitrogen increased as well. The amount of mobile phosphorus increased, and mobile potassium decreased. Sapropel improved the composition of humus (C<sub>HA</sub>:C<sub>FA</sub> = 0.74&ndash;0.77; in control = 0.71). The results of investigations have shown that after 18 years of application the higher rates (150, 200 t/ha) of dry sapropel increased the productivity of crops. The highest rate of sapropel (200 t/ha) was almost of the same effectiveness as manure applied in every rotation.
