Change of grey forest soil fertility in field crop rotation

DOI: 10.24411/0235-2516-2019-10018

In the grain crop rotation the highest content of organic matter in the soil was recorded in the variants with biological cultivation technology under spring barley (the foregoing crop being manure-fertilized potatoes) – 4.13%, under winter wheat – 2.75%. Applying 40 t/ha of cattle manure under potatoes resulted in the formation of labile organic matter («new» humus) in the soil. In the variants with biological cultivation technologies there was the maximum organic matter supply under all crops in field rotation. The biological cultivation without mineral fertilizing and pesticides applying ensured the arable land productivity of 53.0 с/ha of fodder units. The application of complete NPK rates for the planned yield of the crop rotation led to an increase in the arable land productivity by 1.7 times.

Keywords: fertilizer system, grey forest soil, crop rotation, soil fertility.

Influence of agrochemical parameters of soddy-podzolic soil on agroeconomic efficiency of the phosphorous fertilizers for spring barley cultivation at crop rotation

DOI: 10.24411/0235-2516-2019-10019

In field experiments, a high agroeconomic efficiency of the use of phosphate fertilizers on poorly cultivated sod-podzolic loamy soil (pHKCl 3.9-4.2; Р2О5 35-60 mg/kg) with low content of mobile aluminum (40-48 mg/kg) was established. On cultivated soil (pHKCl 5.1-5.7; Р2О5 95-140 mg/kg) with a low content of mobile aluminum (13-19 mg/kg), the highest rates are achieved with a lower dose of phosphate fertilizers than on poorly cultivated. On poorly cultivated soil with a high content of mobile aluminum (about 130 mg/kg), due to the systematic use of nitrogen and potash fertilizers, the effectiveness of phosphate fertilizers increases with liming.

Keywords: cultivated and poorly cultivated soddy-podzolic soil, phosphorous fertilizers, spring barley, yield, profitability.

Change of fertility at different technologies of soil treatment

DOI: 10.24411/0235-2516-2019-10020

The regularities of change of fertility agrochemical indicators at different technologies of soil treatment are reviewed. It is established that both at plowing and at the minimal treatment, the total nitrogen content increases for 0.03-0.06 mg/kg of soil by the end of vegetation as compared to its beginning. As far as the content of labile phosphorus is concerned, it is noted that in the tillering phase of barley its content in the soil layer 0-20 cm is higher (154.5 mg/kg of soil) at the traditional treatment in comparison with the exact treatment, and the content of labile phosphorus in this option is 136 mg/kg of soil. By the end of vegetation the provision level of this element is 124-180 mg/kg of soil. The content of exchangeable potassium in the layer 0-20 decreases with the accumulation of biomass components by barley plants. Thus, at the beginning of vegetation it is 232.5 mg/kg of soil at plowing, and it is 228.5 mg/kg of soil at the minimal treatment, and by the end of vegetation it is 52.5 and 96 mg/kg of soil, respectively.

Keywords: soil, fertility, dump treatment, minimal treatment.


Studying the effect of long-term application of fertilizers on organic matter of soddy-podzolic soil by method of IR-spectroscopy

DOI: 10.24411/0235-2516-2019-10021

Currently infrared spectroscopy is widely used in physical-chemical studies of soil organic matter. This method allows to obtain, in general terms, the structure of the molecule of humic acids, to follow the changes occurring in them under the influence of various factors, primarily anthropogenic. In this work, a study was conducted to identify changes occurring in humic acids during long-term fallowing of the soil, the application of mineral and organic fertilizers, and also without them in permanent crops of winter rye. It was revealed that the presence of an absorption band caused by the stretching vibrations of methylene groups is characteristic of all humic acids. The application of organic and mineral fertilizers increases the heterogeneity of the components of humic acids and the role of the peripheral part in the composition of the molecule, and prolonged fallowing increases the central part.

Keywords: IR-spectroscopy, humic acids, organic matter, valent and deformation vibrations, spectra, absorption bands, intensity.

Energy-informational effect of herbicide on plants

DOI: 10.24411/0235-2516-2019-10022

Despite the significant reduction in doses of chemicals for the protection and preservation of crops, claims to their use do not subside and remain justified due to the harmful effects on the environment. The method of mediated energy-information signal transfer to plants through the effector medium is presented and certain provisions of the methodology of variational synthesis are confirmed. The possibility of reducing the concentration of herbicide in 10 and 100 times of the recommended dose while maintaining the required level of inhibition of growth and death of model dicotyledonous plants.

Keywords: herbicide, dose, energy-information transfer, research methods, dicotyledonous plants.

Experience of database creating for model of automated system of agroecological assessment of soils and lands, adapted to urban conditions

DOI: 10.24411/0235-2516-2019-10023

Describes the main aspects of the agroecological evaluation of soils in the conditions of urban ecosystems on the example of pilot plots of Environmental experiment of Russian Timiryazev State Agrarian University (RSAU – MTAA). It was determined: the dynamics of agrochemical characteristics for 2017-2018, as well as their variation within one area, the influence of weather factors and different food systems on grain yield. As a result of the study, it was possible to reduce the range of values of a number of parameters of intra-field variation in agrochemical characteristics, for example, in the southern field in 2017, the minimum acidity values locally reached 7, and the maximum to 8.35, then in 2018 the minimum value is 7.4, and the maximum 8. A similar phenomenon was noted in relation to other parameters, but despite the decrease in the content of mobile phosphorus, locally recorded low anthropogenic eutrophication of site, which can be explained by the intense impact of a nearby urban ecosystem on the resistance of agrocoenosis. Monitoring of abiotic factors (temperature and soil moisture) throughout the vegetation period revealed 14 days with a high stress load on the growth and development of barley plants in May and 15 days in June, which adversely affected the growing season of crops, high yields (2,60 t/ha) in the southern field identified in barley cultivar Vladimir (in the variant with application of ammonium nitrate and biopreparation Agrinos). The lowest yields were obtained on Central field in the variant with application of ammonium nitrate in conjunction with Bisolbifit and Extrasol (1.94 t/ha), what may depend on the internal variation of both agrochemical characteristics and the complex influence from the urban ecosystem.

Keywords: agroecological assessment, grain crops, soils.

Yield of barley grain and its dependence on level of mineral nutrition and hydrothermal conditions during vegetation period

DOI: 10.24411/0235-2516-2019-10024

The dependences of barley grain yield on increasing level of mineral nutrition and hydrothermal conditions in different interphase periods of vegetation are presented and discussed. These dependences have a complex nonlinear view and are most accurately described by second-order equations with clearly defined extremum points or areas of optimum. To the maximum degree (at largest of the coefficient of determination – R2) the yield of barley grain is related to hydrothermal conditions during the period of shooting – earing and the entire vegetation period (sowing – full ripeness). The hydrothermal coefficient (HTK by G.T. Selyaninov) during the vegetative period (sowing – earing) does not always correctly reflect the dependence of the yield on the hydrothermal conditions prevailing during the given growing season.

Keywords: barley, yield, mineral fertilizers, hydrothermal coefficient, interphase periods of vegetation, multiple regression analysis.

DOI: 10.24411/0235-2516-2019-10025

The results of studies of the effect of foliar fertilizing of winter rapeseed with solutions of potassium iodide with a concentration of 0.01 to 0.1% in the bud budding phase. It has been established that in a specified range of concentrations, plants absorb iodine by a barrier-free mechanism. The stimulating effect of microfertilizer on the accumulation of nitrogen by the plants in the phases from the onset of budding to the onset of flowering has been revealed. It has been established that the use of potassium iodide in the concentrations studied does not adversely affect the oil content of the seeds. In the conditions of the Kaliningrad region, the expediency of foliar treatment of plants of winter rape with 0.01% KI solution along with treatment with an insecticidal drug has been proved.

Keywords: potassium iodide, winter rapeseed, foliar treatment, yield.

Influence of oil pollution on agrochemical and toxicological indicators of soddy-podzolic soils

DOI: 10.24411/0235-2516-2019-10033

The results of the influence of a wide range of oil pollution doses (from 1 to 60 g/kg abs. dry soil) on toxicological and agrochemical indicators of soddy-podzolic soils are presented. It has been shown that the most common in practice, the GOST method of determining the content of petroleum products using IR-spectrophotometry allows determining in polluted soil from 63 to 94% of these compounds. As the Standard for permissible residual oil content and its transformation products for soddy-podzolic loamy soils in conditions of the Udmurt Republic, it was proposed to recommend the content of oil products – 4.3 g/kg (based on toxicological analysis on two test objects: Paramecium caudatum Her and Daphnia magna Straus). The negative impact of oil pollution on the amount of exchange bases in the soil and the content of mineral nutrients in it has been established. The parameters of changes of these agrochemical indicators were directly dependent on the level of pollution, which allows them to be used as indirect indicators to assess the degree of contamination of soddy-podzolic soils with oil products.

Keywords: oil pollution, soddy-podzolic soils, permissible residual content of oil and oil products in the soil, agrochemical indicators, soil toxicity.
