Plant-based fertilizers, such as liquid plant extracts, contribute to the cultivation of vegetables, particularly in organic production. The objective of this study was to determine if aqueous nettle extract could be successfully used as a fertilizer, applied on the soil and foliarly, in green bean production under field conditions. The hypothesis was that it could successfully replace mineral fertilizers and be integrated into sustainable and organic agriculture. The experiment was conducted at two climatically and pedologically different locations (Zadar and Poreč) throughout two growing seasons (spring and autumn). Two types of aqueous nettle extracts were used: a short-term extract (SE) was prepared by the extraction of wild stinging nettle (183 g 10 L−1 of water) in water for 24 h, while a long-term extract (LE) was prepared at the same ratio with water extraction for 14 days. Both extracts were diluted with water at a ratio of 1:3 (extract:water) before use. The SE was applied foliarly, and LE, by pouring it onto the soil. The abovementioned treatments were compared with mineral fertilization with urea (U) and control (no fertilization (C)). Foliar fertilization with SE proved to be almost as efficient as fertilization with LE, poured onto soil, showing a positive effect on green bean vegetative parameters. Furthermore, aqueous nettle extracts showed a positive effect on the iron accumulation in the leaves.

The amount of available water to certain crops can play a direct influence on the expected effect of the application of fertilizers, whether mineral or organic origin. Thus, this work was performed in order to evaluate the effects of the application of different irrigation depths and organic and mineral fertilizers in the development and production of sunflower plants in Ceará state, Brazil. The experiment was carried out in full sun in pots containing Alfisol, in a completely randomized experimental design with a 5 x 3 factorial, five irrigation depths (L1 = 50%, L2 = 75%, L3 = 100%, L4 and L5 = 125% = 150% of the Class-A Tank evaporation ECA) and three fertilizations (F1 = organic, using aerobic fermentation of Bovine biofertilizer, F2 = mineral fertilizers, NPK-based and F3 = control without an addition of fertilizers with five replications. At 65 days after sowing (DAS), the following characteristics were analyzed: number of leaves, stem diameter, and plant height. In the maximum development of achenes (about 90 DAS), the plants were harvested to determine the head diameter, dry mass of 1000 seeds, dry mass of sunflower head, seed dry mass and crop yield. The different depths applied causing a significant effect in all the sunflower crop yield parameters being as low as the effect of the applied lower depth. The application of biofertilizers in plants provided increments similar to those provided by the application of mineral fertilizers in stem diameter, dry mass of the sunflower head, the head diameter and seed dry mass under different irrigation depths. Since most applied irrigation depth (150% of the ECA), combined with the mineral fertilizer and bovine biofertilizer provided higher results in sunflower production.

Purpose. To study the regularities of influence of fertilization system on alfalfa seed crops under the use of mineral, lime and various types of water-soluble fertilizers on a chelate basis in conditions of increased soil acidity in order to form maximum seed productivity. To establish the features of formation of the sowing properties of seeds, in particular, the germination energy, germination capacity, the number of hard seeds and the mass of 1000 seeds, their variability, and on this basis to develop ways to improve them. Methods. Measuring, visual, quantitative, laboratory, mathematical and statistical. Results. As a result of scientific research, the possibilities of increasing the seed productivity of alfalfa in conditions of excessive acidity of gray forest soils of the Forest-Steppe of Ukraine were discovered. It has been established that the introduction of lime, mineral and water-soluble fertilizers on a chelate basis in different phases of growth and development of alfalfa reduces the negative impact of the lack of basic nutrients for seed plants, especially calcium, and promotes increase in seed productivity by 124-236%, the weight of 1000 seeds – by 10-17%, germination – by 1-5%. Conclusions. Optimal conditions have been established for the formation of the Sinyukha variety alfalfa seeds yield on gray forest soils with increased soil acidity (pH 4.8-5.2) by liming alfalfa with a fastacting calcium fertilizer (Ca(OH)2 – slaked lime) – 0.5 norm up to hydrolytic acidity in combination with the use of mineral fertilizers (N30P90K90). The most effective is the use of “Raykat Start” growth and development regulator at the beginning of regrowth and “Raykat Grow” at the beginning of flowering alfalfa in a dose of 125 ml per 100 l/ha of water in combination with the introduction of water-soluble fertilizer Plantafol (1 kg/ha), boric ( 1 kg/ha) and molybdenum fertilizers (0.3 kg/ha) against the background of the main fertilization with mineral and lime fertilizers, which provided, on average, over the years of research, the formation of the highest seed yield – 235-264 kg/ha, 1000 seeds weight – 1.86 g, seed germination – 95%.

The article presents the studies carried out in 2017 and 2018 in the central zone of the Krasnodar Territory on the basis of the Agrotechnological Department of the FSBSI «National Center for Grain named after P.P. Lukyanenko». The purpose of the research was to study the dose and frequency of application of mineral fertilizers with a complex of NanoSilicon microelements, stimulating growth and development of corn and, ultimately, its yield and quality of the obtained products. Two year studies revealed the effectiveness of the positive effect of the studied drug on grain corn in all studied options. It was noted that at low or high doses of its application, a number of indicators that determine the structure of the crop and, ultimately, yield, decreased. It was found that foliar treatments increased the growing season of corn for a day. The introduction of the preparation promoted the formation of taller plants, the height of which varied from 201,3 to 212,4 cm, while in the control it was 184 cm (milk ripeness phase). In the same phase the plants had a large biological weight, which in the control was 1010,1 g/plant, and when the preparation was applied, it was 90,2–275,5 g/plant higher. Ultimately, mineral fertilization with the NanoSilicon microelement in all studied dosages had a positive effect on the corn yield, the maximum value, which was obtained when it was applied at doses of 40/75/75 (seed treatment with NanoSilicon with a rate of 40 g/ha + application by seedlings at a dose of 75 g/ha + in the phase of 7–8 leaves 75 g/ha) and 40/100/100 (seed treatment – 40 g/ha + seedlings – 100 g/ha + in the phase of 7–8 leaves – 100 g/ha), which amounted to 59,9 and 59,8 c/ha, respectively.

The research aims to establish the eff ectiveness of granular chalk use produced by «Slavuta-Calcium» Ltd. under growing Poliska–90 winter wheat variety, changing the physicochemical properties of grey forest soil and the wheat productivity. It also aims to establish optimal dosis of «Slavuta-Calcium» granular chalk as the meliorant and mineral fertilizer for grey forest soil in the system of winter wheat fertilization. In the temporary fi eld studies, various doses of nutrients N60–90–120P30–45–60K60–90–120 combined with «Slavuta–Calcium» granular chalk in a dose of Ca230–460–690 kg/ha of the active substance were studied against the background of secondary plowing of rotation products – soybean biomass that averaged 2.34 t/ha. Granular chalk is a modern complex highly eff ective meliorant with the content of Ca – 37.7 and Mg – 0.2 %, the mass fraction of carbonates (CaCO3 + MgCO3) makes at least 95 %. It is characterized by a high level of solubility when interacting with moisture in soil. It has a form of white granules, the mass fraction of 4.0–6.0 mm in size granules makes not less than 90 % and the one of 1.0 mm in size makes less than 5 %. Reactivity – 97 %. The granular chalk is advisable to apply on acidic soils, as a highly concentrated calcium-magnesium fertilizer, with the former as the dominant fertilizer, to optimize the physicochemical properties of the soil, as well as the plant nutrition system, in particular, increasing the availability of an element for assimilation by plants and as long-term ameliorants. The eff ectiveness of the use of mineral fertilizers, in particular acidic nitrogen on highly and medium acidic soils, after chemical reclamation is increased by 30–50 %, and slightly acidic by 15–20 %. The increase in productivity of crops from the combined eff ects of nutrients and chalk granulated is usually higher than when separately applied. The eff ectiveness of the integrated action of these elements is manifested in the growth of plant productivity and the quality of the resulting products, as well as the optimization of physical chemical properties and soil buff ering in the long term. In order to optimize the physicochemical properties of the arable layer of gray forest soil and the productive nutrition of agricultural crops, winter wheat, in particular, biogenic elements should be used in doses N60-90-120P30-45- 60K60-90-120 with granulated chalk «Slavuta-Calcium» in doses of Ca230-460-690 kg/ha of active substance. Granulated chalk obtained as a result of industrial grinding of solid sedimentary carbonate rocks of natural origin, subsequently under the infl uence of the granulation process of the starting material contains Ca and Mg carbonates of at least 95 %, dense granules which facilitates convenient mechanized application, as well as chalk suitable for accurate metered application on the quest map. Key words: granular chalk, gray forest soil, chemical reclamation, crop productivity.

In this paper we provide new data about the soil enzyme activity as a biological process, which is an indicator for impacts of factorial combinations of lime and fertilizers applications. Five plots divided into fifteen subplots were sampled for determination of the enzymatic indicators of soil quality, based on the actual and potential dehydrogenase and catalase activities. The research revealed that limed soil samples, in comparison with unlimed ones, resulted in significantly higher soil enzymatic activities (p[0.05) in the upper (0-20 cm), while in the deeper (20-40 cm) layer, only catalase activity was significantly higher (at least at p[0.02). Mineral fertilization, in comparison with its farmyard manuring, led to an insignificant increase in each of the three enzymatic activities determined, excepting catalase activity which was significantly higher (0.05]p]0.02) in the 0-20 cm layer. Based on the absolute values of the enzymatic activities, the enzymatic indicators of soil quality (EISQ) were calculated. The mineral NPK-fertilization and low dose of lime in the 0-20 cm layer, and mineral NP-fertilization and low dose of lime in the 20-40 cm layer proved to be the best variants of fertilization. The enzymatic indicators of soil quality in these variants reached the highest values: EISQ=0.821 and EISQ=0.889, respectively, indicating the presence of high enzymatic activities. It should be emphasized that a balanced application of lime, mineral fertilizers and farmyard manure leads to the formation of favorable conditions for the development of microorganisms, growth of plants and for an intense and lasting enzymatic activity.

Digestate from biogas production can be recycled to the soil as conditioner/fertilizer improving the environmental sustainability of the energy supply chain. In a three-year maize-triticale rotation, we investigated the short-term effects of digestate on soil physical, chemical, and microbiological properties and evaluated its effectiveness in complementing the mineral fertilizers. Digestate soil treatments consisted of combined applications of the whole digestate and its mechanically separated solid fraction. Digestate increased soil total organic C, total N and K contents. Soil bulk density was not affected by treatments, while aggregate stability showed a transient improvement due to digestate treatments. A decrement of the transmission pores proportion and an increment of fissures was observed in digestate treated soils. Soil microbial community was only transiently affected by digestate treatments and no soil contamination from Clostridiaceae-related bacteria were observed. Digestate can significantly impair seed germination when applied at low dilution ratios. Crop yield under digestate treatment was similar to ordinary mineral-based fertilization. Overall, our experiment proved that the agronomic recycling of digestate from biogas production maintained a fair crop yield and soil quality. Digestate was confirmed as a valid resource for sustainable management of soil fertility under energy-crop farming, by combining a good attitude as a fertilizer with the ability to compensate for soil organic C loss.
