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.

Mechanical Cleaning

Approx. 1.5 billion m3 of sapropel are accumulated in silty Lithuanian lakes. Sapropel is a valuable organic and limy matter, which can be used for fertilisation and soil improvement. Silted lakes usually require mechanical cleaning, i.e. removal of lake sapropel. Such cleaning was carried out in one of the lakes of Lithuanian – Lake Ilgutis: using a dredge, sapropel was extracted, dried in sediment bowls to 80–85% of humidity, carried to a field and insert into the soil. Summarised results of the long-term experiment showed that calcareous sapropel can reduce soil acidity and increase the amount of exchangeable bases (Ca+Mg). Under the influence of sapropel, the contents of organic carbon and total nitrogen increased as well. The results of investigations demonstrated that by the end of the second (after 12 years), third (after 18 years) and fourth (after 24 years) rotation, the effect of sapropel on soil chemical properties was positive. Compared with limestone, calcareous sapropel improved physical characteristics of the soil to a greater extent. Santrauka Uždumblėjusiuose Lietuvos ežeruose susikaupę apie 1,5 mlrd. m3 sapropelio. Sapropelis, vertinga biogeninė organinė ar kalkinė medžiaga, gali būti plačiai naudojamas dirvoms tręšti ir gerinti. Ežerai, kasant sapropelį iš jų, būtų išvalomi ir pagilinami. Tai padėtų atkurti jų būklę, funkcinę paskirtį. Žemsiurbe MZ-8 buvo kasamas sapropelis iš Ilgučio ežero ir sėsdintuvuose džiovinamas, tada išvežamas į laukus, ir tręšiama dirva. Nustatyta, kad dirvožemio agrocheminės savybės kas rotacija prastėjo, tačiau nepasiekė rodiklių, buvusių prieš bandymų rengimą. Teigiamas sapropelio veikimas pastebėta po antrosios (12 metų), trečiosios (18 metų) ir ketvirtosios (24 metų) sėjomainų rotacijų. Sapropelis laukams tręšti turėjo teigiamos įtakos dirvožemio fizikinėms savybėms. Kalkinis sapropepelis veikė geriau nei klintmilčiai.

Effect On Yield

In recent years, sustainable agriculture has revitalized interest in crop rotations and their effects on crop performance and agroecosystem biodiversity, including weeds. This article used winter rye as an example and focused on the crop rotation (CR) impact on species, taxonomic and functional diversity of weed communities and analysed the contribution of crop rotation to protecting yield and regulating weed abundance. Long-term continuous rye cropping (CC) provided a background for comparison. Two variants of plant protection were also adopted: herbicide application (H+) and no plant protection (H−). The data from the 10th, 30th and 50th years of the experiment were included in the analysis. Diversified crop rotation with no chemical protection resulted in a satisfactory rye yield and reduced weed abundance—especially problem species—without a decrease in weed species diversity or functional diversity. When rye was grown under crop rotation, the herbicide application had no effect on yield protection, but it was harmful to weed biodiversity. The rye yield correlated negatively with weed biomass, but did not show a link with weed biodiversity. Continuation of long-term experiments as a research basis for contemporary and future scientific challenges is necessary.

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.

Abstract The research was carried out continuously since 1923 in a permanent fertilisation experiment at the Experimental Station of SGGW in Skierniewice. The objective of the research was to determine the effect of long-term fertilisation (Ca, CaNPK, NPK) and crop rotation systems (rye monoculture without fertilisation with manure and five-field rotation with legume crop and manure fertilisation) on selected physical and chemical soil properties. Long-term fertilisation caused various degrees of change in many physio-chemical properties in three soil horizons (Ap, Eet, Bt): pH in KCl, cation exchange capacity, total exchangeable bases, base saturation, content of carbon, nitrogen and mineral forms of nitrogen (NO3, NH4) as well as the carbon-nitrogen ratio. The combined manure and mineral fertilisation increased the sorption capacity, total exchangeable bases, base cation saturation and total content of C and N in comparison to organic or mineral fertilisation. As a result of lime application, an increase in these parameters was determined with the exception of total contents of carbon and nitrogen, showing no differences or a decrease. A positive effect was confirmed in five-field crop rotation, which improves physicochemical soil properties in comparison to cereal monoculture. The C:N ratio narrows down with growing depth because more nitrogen than carbon migrates down the soil profile.
