Features of heavy metals distribution in soils of agricultural lands in exposure zone of Lipetsk industrial agglomeration

The regularities of distribution of heavy metals in the snow cover and soils of agricultural lands of the impact zone of enterprises of the Lipetsk industrial agglomeration were studied. It is established that the main fallout occurs at a distance of 2-3 km from industrial enterprises. The content of heavy metals in the soil varies significantly depending on the source of pollution, the direction and nature of the underlying surface. Most of the heavy metals are concentrated in soil layers 0-2 and 2-5 cm, the content of which is 1.2-8.5 times higher than in the parent rock.

Returning of farmlands previously withdrawn from agriculture due to Chernobyl NPP accident back to it’s agricultural use in Belarus

Proposes crop rotation schemes developed based on multi-year experiments studying cultivation of agricultural crops on soddy-podzolic soils withdrawn from agricultural use due to their radiation hazard in the first years after the Chernobyl NPP accident. It was established that in order to return previously withdrawn lands back to their agricultural use it should be mandatory to implement a complex of agrochemical and agrotechnical protective measures (e.g. lime treatment, application of phosphorus and potassium fertilizers, selection of crops with low radionuclide uptake characteristics). In view of the high levels of accumulated radionuclides (90Sr in particular), the use of agricultural products from such lands should be restricted (it should be used exclusively for feeding purposes as forage or be further processed for technical purposes).

Keywords: radionuclides 137Cs and 90Sr, soddy-podzolic soils, crop rotation, radiation hazard, Belarus Republic.

Estimation of increased dozes of poultry manure and vermicomposts on agrochernozem fertility and yield of wheat

The problem of utilization of industrial poultry wastes is one of the most urgent environmental problems, as the accumulation of poultry manure causes pollution of the environment and raises the alarm of sanitary and epidemiological surveillance and environmental authorities. The effect of increased doses of bird droppings and vermicompost on agrochemical indicators of agrochernozem and wheat yield was studied in the field stationary experiment (2012-2014) in the conditions of the Krasnoyarsk forest-steppe. A decrease of their quantity is connected with transformational processes in soil and their expenditure for the purpose of forming wheat yield. A maximum quantity of easily hydrolyzable nitrogen in fallow soil accumulates under the influence of vermicompost and is spent in wheat agrocoenosis. All the organic fertilizers under study ensure a positive phosphorus balance, and double and triple doses of fertilizers do the same with regard to nitrogen. The study shows the dependence of wheat yield on total and easily hydrolyzable nitrogen in soil, which allows us to make a high-precision prediction of wheat yield.

Keywords: agrochernozem, agrochemical properties, bird droppings, vermicompost, wheat, yield.

Influence of complex fertilizer Suprodit-M on yield and quality of agricultural crops at the application of sewage sludges

The paper presents the dates of studies on the effect of a new complex fertilizer SUPRODIT-M with a ratio of N:P:K = 1:1.1:1.6, having the properties of a sorbent containing humates of potassium and enriched with Mg, B, Mo, on the productivity of spring barley and oat, grain quality and content of the heavy metals (HM) when using dehydrated sewage sludge (DSS) on soddy-podzolic sandy soil. It is established that the combined use of SUPRODIT-M and DSS increases the grain yield by 1.5 times, and oats – in 3.8 times in comparison with the control. Making DSS in the dose of 10 t/ha for barley allows you to get a grain of barley with the contents of the HM corresponding to sanitary norms 2010. Using of DSS in the cultivation of oats ensures the production of grain only for forage. In a joint soil SUPRODIT-M and DSS the HM content in barley grain reduced 1.1-1.4 times, and in grain of oats – 1.4-2.1 times in comparison with the introduction of some DSS.

Influence of soil-climatic conditions on efficiency of biopreparations and nitrogen fertilizers for barley cultivation

It was discovered that there’s a connection between the agrochemical properties of sod-podzolic soil, weather conditions of the growing season and the efficiency of biopreparations on spring barley. The study is based on the results of 43 field experiments. The mathematical model of the low-order of the forecast increase of the spring barley’s grain yield during the process of the microbial preparations’ inoculation based on associative rhizosphere diazotrophs has been developed. The use of this model will allow to identify the application efficiency of biologics, depending on the availability of soil humus, the reaction of the soil solution and meteorological conditions during the vegetation period. It has been established that the greatest spring barley’s grain yield increase from the biopreparations’ inoculation on the background of PK-fertilizer can be obtained when the humus content is equal 2.5-2.7%, the neutral soil environment (pHKCl 6.1-6.7) and hydrothermal coefficient of Selyaninov (SCC) in May-June period 1.3-1.8.

Hypothesis of humic substances physiological activity demonstration in aspect of humification process

A hypothesis is presented explaining the manifestation of the physiological activity of the various humic substances formed during the transformation of organic matter into humus. The structural and physiological similarity of different fragments of humic substances with natural phytohormones, which have as their basis a single aromatic matrix, originating from the most resistant to decomposition of lignified plant remains, is analyzed. It is shown that the transformation of organic matter into humus can be conditionally divided into three stages. At the first stage, during the oxidation-hydrolytic transformation, lignin structures are aromatized, carboxylated and demethoxylated, acquiring the properties of analogues of humic acids. The resulting lignohumic acids (LGA) are structurally and physiologically similar to natural gibberellins. At the second stage, when nitrogen is included, indole type compounds are formed in the structure of LGA – they are close to natural auxins. The final stage is characterized by saturation of the aromatic matrix with nitrogen, while nitrogen is not only included in the periphery, but is also built into the heterocycle, forming structures close to natural cytokinins.

Keywords: organic matter, transformation, physiological activity, humic substances.

Efficiency of various ways of mineral fertilizers seal into soil in conditions of Central chernozem region

Three years' researches showed that when forming efficiency of sugar beet batteries differently influenced this indicator: the greatest importance was shown by nitrogen, then phosphorus and potassium, and in case of superficial seal of mineral fertilizers since fall phosphorus and potassium didn't provide reliable increases of crops. The maximum exit of sugar from unit of area was provided by pair combinations with nitrogen (6.28 t/ha), and also threefold fertilizer (6.44-6.64 t/ha). As for types a basis of processing of the soil, on option without fertilizers more big harvest (33.2 t/ha) crop is received on plowing, though distinctions on productivity don't go beyond the 95% level of probability. Distinctions in productivity on full fertilizer are reliable on the significance value accepted in biological researches, the greatest efficiency (42.3 t/ha) was provided by introduction of mineral fertilizers under a plow. On average in three years the best economic results were provided by a method of calculation of doses of fertilizers on a crop increase.

Content of main nutrients in ordinary chernozem and productivity of field crops in crop rotations at Middle Transvolga area

The importance of long-term use of mineral fertilizers, plant residues, soil treatment systems in the accumulation of basic nutrients in ordinary chernozems of the Middle Transvolga, and the high efficiency of the application of mineral fertilizers in the transition to savings systems for their use has been established. The introduction of siderates and perennial grasses into crop rotation, as well as the use of straw as fertilizers, increases the content of nitrate nitrogen by 32-35%, the mobile phosphate by 7.0-7.6% and stabilizes the potassium regime in comparison with the cereal crop rotation. This makes it possible to increase the payback of fertilizers, which must be taken into account when developing systems for the reproduction of soil fertility. With the long-term application of modern technological systems for tillage and sowing, the supply of soils with nitrogen is stabilized, the content of mobile phosphates in it increases by 14.1-17.8%, the exchangeable potassium content by 14.9-22.7%. The highest productivity of crop rotation (1.82 tons of feed units/ha) was established with differentiated tillage, which is 2.8- 5.2% higher than other options.
