Standards improvement for determination of winter wheat requirement in the mineral fertilizers
Method of nutrients doze determination for agricultural crops according to recoupment standards of the mineral fertilizers elaborated by ARSRI for agrochemistry by harvest of grain crops rise is presented in article. As opposed to basic methods this one allows to establish scientifically based yield to each field in dependence ofagrochemical properties and determine nutrients doze and it recoupment by harvest rise, forecast economic efficiency of mineral fertilizers.
Keywords: fertilizer dozes, fertilizer profitability standards, planning yield, economic efficiency.
SOIL PROPERTIES AND PRODUCTIVITY
Agroresource potential dynamics in economies of Leningrad region
The dynamic of agroresource potential (ARP)on example of 3 leading economies inLeningrad region based on analysis of yield (1968-2012) is shown. Yield decrease periods and decrease of ARP concurred to USSR breakdown are determined, subsequent period of ARP growth during 2000 provided by increase ofagriculture production is noticed.
Keywords: agroresource potential, yield, dynamics.
The effect of different rates of mineral fertilizers on the DNA concentration and the total biological activity of chernozem soil
The changes in biological activity and soil-biological processes of chernozems under the impact of fertilizers were studied. It was shown that the quantitative analysis of total DNA may be a marker of the ecological state of the soil, used in agriculture.
Keywords: biological activity, agrochernozem, total DNA, soil-biological processes, mineral fertilizers.
Physicalchemical cluster of agrogrey soil fertility
The physic-chemical sector of agrogrey soil fertility is devised which is an information basis for soil stability towards an acidification, heavy metal accumulation, nutrient depletion.
Keywords: soil, physical-chemical properties, fertility.
Level control of ground water to its effect on soil food regime
The article examines the impact of drainageon the dynamics of the main elements ofthe soil, and also notes the need for regulation of ground water level during the vegetation period. Are the various technological schemes to automate the management of reclaimed water regime arrays to influence dietary regimes peat soils.
Keywords: rate of drainage, vegetation period, feeding regime, batteries, groundwater levels, yield.
The gradient of the physical fields and soil properties as a factor of fertility
It has been shown that the gradient of the physical fields in the soil-plant system is an essential characteristic of the system and an important factor of the soil formation and soil fertility.
Keywords: soil, concentration gradient, substance migration.
BIOPREPARATIONS, HUMATE FERTILIZERS AND QUALITY OF HARVEST
The action of biologics on the photosynthesis activity of barley
Results of biopreparation based on protective-stimulating complexes and mixtures of Zircon influence on photosynthetic activity, quality of seed material, growth, development and yield of barley plants inthe Central areas of Non-Chernozem zone are presented. High correlative response of yield and plant leaf surface is determined.
Keywords: biopreparations, activity of photosynthesis, plant growth regulator, spring barley.
Plant growth regulators and humate preparations activity for non-root topdressing of Jerusalem artichoke
Studied the action of plant growth and humic fertilizers on plants of Jerusalem artichoke in the soil-climatic conditions of the non-Chernozem zone of the Russian Federation. It is shown that the growth regulators and humic fertilizers stimulates the growth and development of plants, increases productivity, improves quality of production, increase the content of biologically active substances in products.
Keywords: plant growth regulators, humate fertilizers, Jerusalem artichoke, yield, production quality, biologically active compounds content.
Elemental composition of oats beans grown in the Middle Cisurals
Studied the elemental composition of the oat grain Konkur. Found that the elemental composition of the grain depends on weather conditions vegetation period. Regarding the highest content of chemical elements observed in a more favorable meteorological conditions vegetativeyear. The heavy metal content does not exceed the maximum permissible concentration, and the resulting products are recommended for the production of dietary products.
Keywords: оat, elemental composition, meteorological conditions.
The effect of the foliar application of the mineral fertilizers on photosynthesis potential of the winter wheat in the forest-steppe of Ukraine
The influence of different compositions of fertilizers application on photosynthesis potential of winter wheat was determined. The optimal combination of bases application and foliar application was provedexperimentally. It guaranteed to get maximal yield of grain. It was 7,51 t per ha.
Keywords: winter wheat, fertilizers, foliar application, the area of leaves, clear productivity of photosynthesis, yield.
YOUNG SCIENTISTS RESEARCHES
Effective use of fertilizers on the basis of sewage sludge and zeolites on depleted peatlands
The article presents materials of researches on studying influence of fertilizers based on sewage sludge and zeolite on agrochemical properties of worked out peat deposits, growth, development and productivity of plants of spring rape.
Keywords: depleted peatlands, springrape, sewage sludge, zeolite.
Estimation of non-root top-dressing of barley and potato by humate preparations on various basement
In a field experiment on sod-podzolic sandy soil influence of not root processing by humate preparations on various backgrounds a food on efficiency of a potato and barley in the conditions of the Pskov area isstudied. High efficiency of humate preparations on various backgrounds a food is revealed. The greatest increase of a crop of a potato is received from gumimax, and barley from humate Na on organic mineral a food background.
Keywords: humate preparations, a potato, barley, not root processing, organic mineral fertilizer system, humate Na, gumimax.
Management of table potatoproductivity in original seed breeding
Results of drop irrigation systemtests for research of complex water-soluble fertilizers influence on potato yield growing in vitro in the greenhouse are presented.
Keywords: potato, fractions of tubers, soil nutrients, drop irrigation, harvest.
Estimation of poultry manure and barley straw application with sod-podzolic sandy soil
Entering of a high dose ofthe bird's dung into a combination to barley straw has led to maintenance decrease in an arable layer of earth of mineral nitrogen, to decrease in acidity of soil,increase in the maintenance of mobile forms of phosphorus and potassium, to increase in productivity and weights of 1000 grains triticale.
Keywords: soil, poultry manure, mineral nitrogen, agrochemical parameters, yield, spring triticale.
Agroecological assessment of soil-grounds at technogenic landscapes in the Nenets autonomous region
The results of the agroecological research of technogenic landscapes of the Nenets Autonomous Region in order to develop measures for biological remediation of disturbed lands. Qualitative assessment based on the analysis of soil content of heavy metals, arsenic, petroleum products, as well as agrochemical and soil parameters is presented.
Keywords: soil-grounds, assessment, drilling sites, tundra, disturbed land, lithostrates.
