USE OF NEUTRALIZED PHOSPHOGYPSUM AS MULTICOMPONENT FERTILIZER FOR RICE CROPS. MESSAGE II

abstract 1131509065 issue 113 pp. 876 – 902 30.11.2015 ru 732
The article shows a possibility of using neutralized phosphogypsum as multicomponent fertilizer for rice crops. In the system of rice fertilization replace of 150kg/ha of ammophos during main application with 40 kg/ha of carbamide and 4 tons/ha of phosphogypsum applied in spring provides the same content of available forms of nitrogen, phosphorus and potassium in soil and plants as with application of N120P80K60. Application of phosphogypsum in spring before sowing is less effective than application in autumn before plowing. When applicating phosphogypsum in spring 2013 with a rate of 4 t / ha the obtained yield was 0.57 t / ha or 8.98% higher than in the control, and in 2014 it was not different from that obtained with the application of solid mineral fertilizers with a rate of N120P80K60. With autumn application of phosphogypsum increase in yield in 2014 was 0.98 t / ha or 12.6%. Yield growth is the result of increasing the survival of plants, grain content in panicle and grain weight per plant. Use of neutralized phosphogypsum is economically feasible. Relative benefits of using phosphogypsum instead of phosphorus fertilizer (ammonium phosphate) on rice crops in the Federal State Unitary Enterprise SRSF "Krasnoarmeyskiy" named after A.I.Maystrenko, Krasnoarmeyskiy district of Krasnodar region at the optimal rate amounted to 13139.7 rubles per 1 ha

USE OF NEUTRALIZED PHOSPHOGYPSUM AS A MULTICOMPONENT FERTILIZER FOR RICE CROPS. MESSAGE 1

abstract 1131509020 issue 113 pp. 244 – 262 30.11.2015 ru 828
Over the past 15 years due to removal with crops of rice crop rotation, as well as with field waste and seepage water content of mobile forms of boron in soils of rice irrigation systems in the Krasnodar region decreased by 10 %, cobalt by 14 %, manganese by 10 %, copper by 7 %, molybdenum by 15 % zinc by 6 %. Impoverishment of soil with calcium and sulfur is observable. Need of using micronutrients for this crop is also determined by lowering mobility of most microelements in flooded soils. Partly this problem can be solved by use of neutralized phosphogypsum – waste product of wet-process phosphoric acid. With its application in dose of 1 t/ha, field receives 265 kg of Ca, 215 kg of S (general) 20 kg of P2O5 and 9.8 kg of SiO2, so it compensates for the loss of calcium from the rice soil, as well as solves the problem of sulfur, silicon and partly phosphorus fertilizers. Data showing possibility of use of neutralized phosphogypsum as multicomponent fertilizer for rice crops are given. Phosphogypsum reduces sparseness of rice plants in ontogeny, thus forming a dense agrocenosis: plant density is 24-25 pcs./m2 that is higher than on application of N120P80K60. Plants with such agricultural background by their height and leaf area did not differ from control ones (N120P80K60), and their dry weight was higher by 2-6 %. With fertilizer system N120P80K60 application of 4 t/ha of phosphogypsum during main fertilizer treatment provides the same level of phosphorus content in the soil and plants, as application of 100 kg/ha of ammophos. Rice yield increases by 0,57 t/ha or 8,98 %. Yield growth is the result of increasing survival capacity of plants, seed setting of panicle and weight of grain per plant

TITANIUM IN THE WESTERN CAUCASUS LEACHED CHERNOZEM

abstract 1121508126 issue 112 pp. 1740 – 1749 30.10.2015 ru 1026
The article presents results of studying total content of titanium in both not fertilized and systematically fertilized black leached soil. Science-based system of fertilizer crop rotation allows solving problems of sufficient balance of nutrients in the system of "soilplant-fertilizer", increasing the quantity and improving the quality of the crop. At the same time, their application is active influence on the natural environment. In the soil, there is an input of a large set of chemical elements come along with fertilizers. In addition, due to their physiological pH or alkalinity, fertilizers are capable to affect the physical and chemical properties of the soil. The use of mineral fertilizers in scientifically based doses on the fields of crop rotation for 33 years virtually has no impact on the content of titanium in leached Chernozem. In the arable layer its number increased only by 2.1 %, and in subsurface - it is the same as in the crop without fertilizer. Enrichment of topsoil with titanium is due to desilication of rocks during weathering. Due to the low solubility of titanium minerals, they remain in the place longer, and therefore, the content of the element in the soil increases. As you know, fertilizers applied to the fields of crop rotation, increase the intensity of the biological cycle of substances and thereby enhance the process of destruction of the parent rocks

THE CONTENTS AND FORMS OF LEAD COMPOUNDS IN LEACHED CHERNOZEM OF THE WESTERN CISCAUCASIA IN TERMS OF AGRICULTURAL SOIL GENESIS

abstract 1301706059 issue 130 pp. 833 – 845 30.06.2017 ru 482
The contents of lead in soils are primarily determined by regional factors: the composition of parent rocks, relief, climate, vegetation. In recent years, these factors have increased the anthropogenic source of element. In order to assess its impact, requires knowledge of the natural, i.e., background lead levels, the so-called reference points, which can later be used to monitor changes occurring in the soil. Under background refers to the content of the element in soils at a great distance from the areas of receipt of contamination. Background content of lead in each type of soil depends mainly on composition of parent rocks. The correlation coefficient between the content of lead in parent rocks and soils, with the background contents is equal to 0,86±0,17 at p=0,95. For each soil type there are low variations in lead content due to the composition of parent rocks. Lead concentrations in the soils increased at the expense of its receipt from the atmosphere, irrigation water, drainage during mining, as a result of agricultural use, lead containing chemicals. Comparing the obtained results with existing currently permissible concentrations (APC, MPC) it is necessary to note that the lead content in leached chernozem soil after three rotations of the rotation may not cause any pathological changes or anomalies in the course of biological processes and lead to accumulation in the agricultural plants, and therefore may interfere with biological optimum

THE CONTENT AND THE FORMS OF MAGNESIUM COMPOUND IN LEACHED BLACK SOIL (CHERNOZEM) OF WESTERN CISCAUCASIA IN THE AGROGENESIS

abstract 1121508124 issue 112 pp. 1717 – 1727 30.10.2015 ru 661
The article presents the results of the study on the magnesium mode of leached chernozem of Western Ciscaucasia at three rotation of grain-grass-tilled crop rotation. Magnesium in the soil is represented mainly by non-exchangeable form, the number of which is estimated at 90,18 and 91,29 % of gross reserves. Exchange forms of magnesium are 8,68 and 7,71 % respectively in arable and the subsurface layer. The share of water-soluble and organic forms account for less than 1 % - of 0.62 and 0.68 and 0.46 and 0.38% respectively. For three rotation 11-full rotation of gross stocks of magnesium in the soil in which crops were grown without fertilizers has decreased by 0.02 % (200 mg/kg), with fertilizers of 0.03 and 0.02 % (300 and 200 mg/kg). Intense magnesium has been leached from the topsoil. There was a change of the soil content of the forms of magnesium. In the rotation without fertilizer, the share of non-exchangeable magnesium in the General Fund item increased from baseline by 0.27 % in arable and 0.11% of the subsurface layer of soil that the absolute content decreased. The amount of water-soluble, exchangeable and organic magnesium of the soil decreased. Reducing the amount of water-soluble (0.05 and 0.06 %) and metabolic (0.18 and 0.02 %) of magnesium was due to its consumption of the plants. The proportion of magnesium organic part of the soil is reduced as a result of steadily declining yields, and, therefore, the amount of organic residues. In crop rotation, use of mineral fertilizers we have observed different behavior of magnesium compounds in the soil. The number of non-exchangeable magnesium decreased from baseline by 0.13 % in arable and 0,58 % of the subsurface layer of soil. The content of the exchange of magnesium increased respectively 0.43 and 0.41 %, water soluble - 0.13 and 0.10 %, and the organic part of the soil - 0.02 and 0.02 %

THE CONTENT AND FORM OF THE NICKEL COMPOUNDS IN THE WESTERN CAUCASUS LEACHED CHERNOZEM IN TERMS OF AGROGENESIS

abstract 1121508125 issue 112 pp. 1728 – 1739 30.10.2015 ru 691
The article presents results of studying the total content and the forms of Nickel in the Western Caucasus leached Chernozem at three rotations of 11-fild grain-grass-arable crop rotation. The Nickel content in the soil is close to its Clark (40 mg/kg) and significantly lower than UEC (80 mg/kg). Scientifically based system for fertilizing crop rotation does not lead to the accumulation of Nickel in the soil, but creates the conditions for increasing its mobility. In the future, we may experience the need of the inclusion of Nickel into the system of fertilization of crops grown on leached Chernozem. The Nickel content in the leached Chernozem before development of crop rotation was generally close to Clark soils of the world (40 mg/kg) and significantly lower than UEC (80 mg/kg), which favors the production of high quality produce. After three rotations of the crop rotation without using fertilizers, the total content of Nickel and acid-insoluble form in the soil decreased slightly, but the number of the element extracted with both buffer and acid extractor, increased insignificantly. The decrease of the total content of Nickel and its reserve (acid-insoluble) fund in the soil we explain with the annual exclusion of the element with harvests crops from the fields, and the trend of increasing mobile and acid-soluble - mineralization of humus followed by acidification of the soil. Systematic mineral fertilization on field crop rotation was slightly up for the Nickel fund of the soil, but did not ensure the recovery of the initial level. At the same time, at fertilize crop rotation we observed a clear trend of increasing the number of rolling and acid-soluble Nickel. If we consider that the value of the MPC for moving Nickel is equal to 6 mg/kg, these changes may not have any negative environmental impacts, but rather will encourage the use of this ultra-microelement by plants

SELENIUM IN BLACK LEACHED SOIL

abstract 1381804041 issue 138 pp. 160 – 170 30.04.2018 ru 422
The content of selenium in the soils of various genetic types varies widely. Its amount is lower in soils formed on volcanic rocks. On average, it is 0.2-0.6 mg/kg. In the soils formed on sedimentary rocks, the content of selenium is often in the range of 4.5-5.0 mg/kg and depending on the conditions of formation it varies widely, sometimes reaching 100 mg/kg. Predominantly they are alkaline soils, selenium concentrations in the soil solution is 10-6 moles. The content of selenium in most soil types of the Russian Federation and CIS countries varies in the range of 0.01-1.0 mg/kg. Floodplain, chestnut soils, black soils and gray soils are more enriched (0.3 to 1.0 mg/kg), whereas sod-podzolic and sandy soils are relatively depleted (0,05-0,2 mg/kg). Systematic application of mineral fertilizers on the fields of crop rotation leads to a decrease in total content in the leached black soil. Fertilizers contribute to increased mobility of this element and more intensive involvement of it in the biological cycle

MICROELEMENTS IN SUNFLOWER CROPS

abstract 1071503039 issue 107 pp. 563 – 577 31.03.2015 ru 1021
The obtained experimental data show that the incorporation of trace elements into the system of the sunflower crop has a positive impact on the mineral nutrition of plants, the number and quality of the crop. Foliar feeding of sunflower crops with micronutrients improves nutrition of plants with nitrogen, phosphorus and potassium, thus creating the preconditions for the formation of highly agrocenosis. The seed yield of sunflower increased by variants with application of micronutrients 1.2-3.5 t/ha or 4.4-12.9 percent. The greatest impact of treatment with boron and copper, exceeding the background option 3.1-3.5 t/ha or 11.5-12.9% respectively. The crop is least influenced by manganese and molybdenum. The examined elements positively influenced the structure of the sunflower crop. The greatest influence on the diameter of the basket, the number of seeds, weight of seeds in the basket, the weight of 1000 seeds was provided by the zinc and copper. Trace elements contributed to the improvement of quality indicators of sunflower. For husk content, the greatest positive effect was cobalt, zinc, manganese and copper, increasing the background option 10.1, 10.4, 10.5 and 10, and 6%, respectively, on the oil content of sunflower seeds had cobalt, copper and zinc. The oil content on these options amounted 55,0, with 55.1 and 55.2%, respectively, increasing this figure by 1.5 to 1.7 %. The acid number at variants with boron, manganese and zinc was the same with the background option and amounted to 1.8. The greatest influence on iodine number provided molybdenum, zinc and copper, which accounted for 170,5, 171,2 and 171,4, exceeding the background option 10.2 and 11.1

CONTENTS AND FORMS OF CHROMIUM COMPOUNDS IN THE WEST FOOT CAUCASUS LEACHED CHERNOZEM IN CONDITIONS OF AGRICULTURAL SOIL GENESIS

abstract 1401806028 issue 140 pp. 123 – 133 29.06.2018 ru 348
Chromium in soils is represented by the following forms of connections: 1) stationary; 2) strongly bound in the composition of primary and partially secondary clay minerals, with one and a half aluminum and iron hydroxides; 3) exchange bound on the surface of one-and-a-half oxides and clay minerals; 4) associated with organic matter of soils; 5) water-soluble compounds. The gross chromium content (70.1-78.3 mg/kg) in leached chernozem is well below clark soils of the world (100 mg/kg). The share of mobile, acid-soluble and acid-insoluble forms of the element compounds is 0.01, respectively; 7.09 and 92.9 % of its gross content. After three rotations of 11-full grain-grass-tillage crop rotation without mineral fertilizers, the chromium content in leached chernozem has not undergone significant changes, even to some extent there is a tendency of its reduction. This indicates the absence of serious natural sources of chromium in the soil. Scientifically-based system of fertilizers for agricultural crops does not lead to anthropogenic pollution of leached chernozem with chromium. The removal of this element with crop yields is compensated by its receipt in the form of ballast with mineral fertilizers

CONTENT AND STATE OF IRON IN WEST LEACHED CHERNOZEMIC SOILS OF WESTERN CISCAUCASIA UNDER CONDITIONS OF AGROGENESIS

abstract 1071503066 issue 107 pp. 967 – 983 31.03.2015 ru 1252
The results of study of groups and forms of iron compounds in leached chernozemic soils of Western Ciscaucasia for three crop rotations according to scheme grain-grass-hoeing are presented. With long-term use of leached black soil in terms of Agrigento there is a substantial change in the contents of the various groups and iron compounds. On the non-fertilized variant of rotation, the total content of this element in the 0-20 cm 21-40 cm soil layer by 69.4 and 66.5% of silicate and by 30.6% and 33.5% free group of compounds of iron. The applied system of fertilizer crop rotation helps reduce the silicate and increase of free group its compounds. In leached black soil a group of desilicated iron in the 0-20 cm layer 24.8 % presents crystallizability and to 75.2% amorphous compounds, 21-40 cm layer, respectively, 26.2 and 73,8 %. Under the influence of fertilizers we have noticed increasing of amorphous and reducing the number of cristallizing forms of the compounds of this element the soil. The number of different groups and forms of iron compounds in leached black soil with systematic use of fertilizers in crop rotation is determined not by the size of introducing this element as impurities, and processes such as the alienation of iron with additional derived products, increase its mobility in the soil due to a shift in the reaction of the soil solution, changes in fractional-group composition of humus. Diagnostic criteria state of iron in the soil are leached quantitative ratio of the content of the various groups and forms of the compounds of this element
