Estimation of energy resource of degraded soils of agricultural lands

DOI: 10.24411/0235-2516-2019-10037

Processes of degradation for the zonal soils of the European part of Russia are considered. The basic agrochemical indicators determining the degree of degradation are substantiated. Theoretical approaches to the estimation of the energy status of the soil depending on the degree of degradation are developed, and the method on the soil bioenergy potential estimation being proposed. The latter is calculated using the amount of ATP which is synthesized by the cell in the complete biological oxidation of the organic matter into carbon dioxide and water, based on its elemental composition based on stoichiometry, the laws of biological oxidation and thermodynamic laws. Knowing the content of elemental carbon, hydrogen and oxygen in organic matter, it is possible to calculate the amount of biogenic energy extracted by the cell in the process of complete biological oxidation of the substrate to carbon dioxide. The above approach gives opportunity to calculate the bioenergy value or bioenergy potential of any organic compound, including the labile part of the soil humus without studying the structure and metabolic pathways. The algorithm of rehabilitation of the degraded soils, including: determination of the bioenergy potential of humus; the calculation of the amount of biogenic energy to restore the optimal functioning of the degraded soils is developed. To replenish the lost energy, the calculated doses of organic fertilizer application were substantiated.

Keywords: soil, degradation, agrochemical parameters, humus, fertility, energy resource, bioenergy potential, lost energy.


History and practical aspects of acid soils liming in Russia

DOI: 10.24411/0235-2516-2019-10038

Years of experience and practice of agriculture have shown continuous acidification and depletion of calcium and magnesium agricultural land, with the result that every year our country gets about 20 million tons in terms of grain. The efficiency of mineral fertilizers is sharply reduced, the ecological situation of the environment is deteriorating, the quality of agricultural products is falling. The article reveals the historical stages of liming, new approaches to this technique associated with the use of raw dolomite flour. It is shown that along with natural lime materials, it is important to use lime containing industrial waste as an important and fairly cheap source of chemical meliorants. Many of them, having a high activity of interaction with the soil, significantly exceed natural carbonates, and the impurities of trace elements contained in them often have a positive effect on the growth and development of cultivated crops. However, most of them may contain a variety of heavy metals and other toxic elements that are hazardous to the ecological status of soils and adjacent environments, and should therefore be subject to comprehensive environmental assessment and regulation based on monitoring results. Much attention is paid to the creation of software and hardware systems for the differentiated application of lime meliorants and mineral fertilizers with the help of modern machines.

Keywords: acidity and soil fertility, methods of liming, ameliorants, fineness of grind, wet-grined dolomite powder, lime containing wastes.

Acidity of arable soils and efficiency of liming in the Kemerovo region

DOI: 10.24411/0235-2516-2019-10039

The data of agrochemical studies and field experiments, which allowed to establish the dynamics of soil acidity from 1966 to the present time, are presented. A measure of the acidity (pHKCl) during this period, decreased by 8%, and there was a transformation of arable land by expanding the area of acidic soils and reducing – neutral from 43 to 10%. Acidic soils appeared even in the steppe regions of the Kemerovo region. In need of liming 141000 hectares of acidic soils and supporting – 430 000 hectares of slightly acidic soils of arable land. For the liming of soils heavy loam granulometric composition specified the optimal values of pHKCl of different soil types and flow CaCO3 to shift by 0.1 pH units. The efficiency of mineral fertilizers on the produced soils increases significantly, the payback of fertilizers for spring wheat ranged from 7.8 kg to 36.2 kg of grain/kg of grain. On the prevailing area of arable land revealed low availability of field crops trace elements Mn, Zn, Cu, Co. It is determined that the yield of spring wheat increases with an increase in the content of trace elements from 10-15 to 30-41 C/ha. After the liming of soils in the cultivation of crops in the Kemerovo region requires the mandatory use of mineral and micronutrients.

Measures for yield increase and reduce of radionuclides inflow into feeds at arable sandy soils

DOI: 10.24411/0235-2516-2019-10040

The results of the researches carried out on the experimental field of Novozybkov Agricultural Experimental Station contaminated by radionuclides have been presented. Various doses of potassium fertilizers (K120-210) have been studied against the background of Р60 application to obtain the highest yields of legumes and cereals and their mixed crops and the maximum reduction of radiocesium content in fodder products. It has been established that the highest yields of green mass among the studied crops was shown by a mixture of blue bastard alfalfa with an awnless brome (in the total for two cuttings). Thus, on the optimum variant (Р60К210) yields of green mass of a mixture was higher, than at alfalfa on 7.6 t/ha, a brome on 23.2 t/ha, the increase from fertilizers was 10.1 t/ha. The researches have established that the guaranteed receipt of normative clean fodder on the basis of blue alfalfa, a awnless brome and grass mixture on their basis is provided by the use of phosphate-potassium fertilizer in the dose of Р60К120. The Increase in the dose of potassium fertilizer to 210 kg/ha led to a decrease in the content of 137Сs in feed.

Keywords: radioactively contaminated lands, 137Сs, phosphorus-potassium fertilizers, blue bastard alfalfa, awnless brome, single species crops, mixed crops, yields.

Change of physiological parameters of spring wheat varieties from technology of their cultivation

DOI: 10.24411/0235-2516-2019-10042

The presented research results were conducted in the conditions of the Central Non-Chernozem regions of Russia on soddy-podzolic cultivated soil. The dependence of the productivity of spring wheat varieties on the value of the photosynthetic potential (PhP), which is regulated by technological elements during cultivation, is shown. As a result of the research, a differentiated level of photosynthetic potential was established in million m2 of days for different varieties of spring wheat using basic, intensive and high-intensity technologies. The composing value of the formation of the harvest of spring wheat is the net productivity of photosynthesis (NPPh). The NPPh establishes the optimal course of the photosynthetic activity of crops for the zone, which makes it possible to determine the necessary conditions for the growth of plants in a specific period. To carry out technological measures effectively. It is established that the magnitude of the PhP depends on the degree of wetting of the growth of plants. Under highly hydrated conditions of PhP, the maximum yield was from 0.84 to 1.03 kg of grain per day from one thousand m2 of the photosynthesizing surface. Under dry conditions 1.56-2.05 kg of grain/thous. m2 per day. This indicator reached its maximum under mildly arid conditions, and, depending on the variety, ranged from 2.32 to 2.49 kg of grain thousand square meters per day.

Efficiency of mineral and organic fertilization systems at soddy-podzolic soil in conditions of deficient nutrition balance

DOI: 10.24411/0235-2516-2019-10043

In the field experience, the relation between the agrocoenosis productivity, the agrochemical properties of soddy-podzolic sandy loam soil, the types and doses of fertilizers at for partial and full return of removal is established. It is shown the deficit balance of nitrogen, phosphorus and potassium leads to a significant lower the productivity of crop rotation regardless of the soil nutrients availability. When using fertilizers in doses that compensate for the 50-60% of nutrients removal, the decrease in productivity was 13-21% in the mineral fertilizer system (N20P23K28) and 25-33% in the organic system (manure 8 t/ha per year) compared to the option with a full return of removal (N40P45K47). For three years of research, the decrease in the content of humus and mobile forms of phosphorus and potassium was noted in the soil with an initial elevated level of nutrients when partial compensation of removal. The combined use of the manure at a dose of 8 t/ha and mineral fertilizers at a dose of N20P23K18 contributed to the maintaining of optimal agrochemical soddy-podzolic sandy loam soil indicators.

Keywords: productivity, crop rotation, soddy-podzolic soil, fertilizer system, agrochemical indicators, balance.
