In lysimetric experiment with soybean, the effect of complex inoculants based on Bradyrhizobium japonicum and Azospirillum brasilense on the vertical migration of biogenic elements have been studied. When growing without application of mineral fertilizers, bacterization helped to reduce losses of nitrogen, phosphorus, potassium, calcium, magnesium compounds, as well as moisture and water-soluble humus. Also reduction in loss of biogenic elements compounds under the action of inoculants on the background of N30 was found, but bacterization not affect the loss of moisture and humus. It was shown that complex inoculants affect biometric parameters of soybean plants and enhances the productivity of this culture.

The paper presents the research results of pre-sowing seeds bacterization with nitrogen fixing bacteria Bradyrhizobium japonicum and Azospirillum brasilense influence on the loss of moisture, water soluble humus and nutrients. It was shown that seeds bacterization reduces the leaching intensity of nitrates, phosphorus, potassium, calcium and magnesium. Moreover, the least losses of nutrients were observed in a variants with joint application of both studied nitrogen fixing microorganisms. It was noted that seeds bacterization with B. japonicum and A. brasilense had promoted increase of chlorophyll content in the leaves of soybean plants. The highest yield was observed in the variant with the joint use of rhizobia and azospirillum.

ABSTRACT This study aimed to verify the effect of co-inoculation, association between Azospirillum brasilense and Bradyrhizobium japonicum bacteria, on soybean plants subjected to water deficit at two sowing dates. Two field experiments were conducted at the Universidade Federal de Tocantins, campus of Palmas, Brazil, in 2016. The experimental design was randomized blocks in a split-split-plot arrangement with four repetitions, where the plots consisted of two irrigation depths (100 and 25% of crop evapotranspiration - ETc), the subplots was composed of two methods of inoculant application (inoculation with Bradyrhizobium japonicum and co-inoculation with Azospirillum brasilense + Bradyrhizobium japonicum) and the sub-subplots comprised two soybean cultivars (TMG 132 and ANTA 82). The cultivars responded differently to the sowing dates. Co-inoculation did not influence grain yield under full irrigation conditions (100% ETc), in neither cultivar evaluated. However, under the water deficit condition (25% ETc), the grain yield of the cultivar TMG 132 increased 77.20%, indicating that there are different responses of interaction between Azospirillum brasilense, plant genotype and sowing dates.

The article presents the results of decomposition of substandard phosphorites at a non-full rate of nitric acid (10-50% of stoichiometry on CaO), followed by its processing by bird droppings in various ratios. The optimal parameters for obtaining organic mineral fertilizers are determined, the technological scheme is given and the material balance is calculated, the possibility of obtaining nitrogen-phosphorus-humus fertilizers based on substandard phosphorites and bird droppings is shown, by composition (wt.%): P2O5 total - 6.53; Р2О5 acceptable - 4.04; СаО total - 17.12; N - 4.21; organic matter - 28.38; humic acids - 9,12, fulvic acids - 5,25, water-soluble organic substances - 4,2; pН – 5,93.

The aim of the study was to establish changes in the physico-chemical and agrochemical characteristics of gray forest large-clay loamy soil, depending on the contamination of ecotopes by heavy metals. Methods. Field, laboratory, mathematical and statistical. Results. The results of the study of the soil of areas with an over-dimensioned content of heavy metals and the transformation of agrochemical characteristics of gray forest soil in the cultivation of corn for grain. It was established that under conditions of systematic application of mineral fertilizers in agrocenoses, an increase in the lead concentration to 100 mg/kg, cadmium to 2,0, zinc to 50 mg/kg in gray forest soil did not result in a decrease in the amount available forms of nitrogen, phosphorus, potassium by plants, compared with the natural background. Concentration of lead in the amount of 1000 mg/kg, cadmium – 20, zinc – 500 mg/kg marked an increase in exchange and hydrolytic acidity and loss of humus.
