AGRONOMIC FACULTY OF STAVROPOL STATE AGRARIAN UNIVERSITY 70 YEARS

Agronomic faculty of Stavropol State Agrarian University – source of personel for Russian agriculture

During its 70-years history the Faculty of Agronomy had prepared more than 10 thousand specialists, who took their dignified places in the agricultural complex of our country. The results of scientific research by the Faculty scientists are widely implemented into the production of agricultural crops, their storage and processing. There are all necessary conditions for training of specialists demanded by the labour market.

Keywords: education, science, production, faculty, achievements.


Dynamic of wheat grain quality changes in Stavropol region

The article summarizes long information about changes of production data of grain quality in dynamics in Stavropol Territory since 1965 till 2010. The reasons which influenced the grain quality changes during last decades are shown. Gross wheat grain data given, the largest regions grown wheat in the South of Russia are compared.

Keywords: winter wheat, Stavropol Territory, protein quality, raw gluten quantity, gross crop.


The quality and yield of spring barley grain by the fertilizers application on leached chernozem

Summary: comparative evaluation of spring barley of grout, forage and beermaking usage corrections on leached chernozem by mineral fertilization has been carried out. The results of the research allows to recommend economically effective rates of mineral fertilizers, which ensure high yields of spring barley of necessary quality, depending on the way of usage.

Keywords: varieties of spring barley, the level of mineral fertilization, productivity.


Influence of microfertilizers on yield and quality of winter wheat grain on leached chernozem

The article contains 2 years information about efficiency of microfertilizers, used by producing winter wheat. The highest productivity of winter wheat was ensured by the combined usage of such medicines as «Micromac» and «Microel». Depending on the main elements of nutrition the average increase of the yields composes about 6-20%.

Keywords: microelements, the means of fertilizers application, yield and quality of grain, mineral fertilizers, additional fertilizing, winter wheat.


Effectiveness of presowing processing of tomato seeds

The optimal parameters of presowing processing of tomato seeds are determined in the result of scientific research. The effectiveness resulted in the improvement of sowing qualities of seeds and adaptive qualities of plants as well as in the increasing productivity of crops.

Keywords: tomatoes, physical factors, ozone, viability, productivity, Zirkon.


The effect of applying rocks on sunflower crop

Intensive use of arable lands results in soil exhaustion. Mineral elements of nutrition are used by plants and are estranged with yield or are gradually watched into deeper layers of soil. The drop level of effective soil fertility takes place and it is impossible to solve this problem only by fertilizer application. The latter leads to the energization of weathering process and carrying-over of new portions of nutrition elements together with yield increase. From time to time it is necessary to carry out the «regeneration» of mineral basis by application of dust material of different rich, with point of view chemical composition, mountainous rock. The aim of given work is the choice of effective methods of leached chernozem fertility increase by its remineralization by various mountainous rocks.

Keywords: leached chernozem, parent rock, phosphorous gypsum, apatite, limestone, loess-like loamy soil.


Effect of predecessors for winter wheat agrophysical parameters of fertility in moderately wet zone

The article touched on the influence of predecessors in the agro-physical factors of fertility. In particular the supply of available moisture and the structural-aggregate composition of the soil, as well as on the yield of winter wheat boundary in moderately humid zone.

Keywords: moisture, structural-aggregate composition, coefficient of structure, cloddy structure, agronomically valuable aggregates.


Silage corn yield on the reclaimed soil in dry zone Stavropol region

The article addresses the issues pioneering, «abandoned» lands and their use in agricultural production in arid zone of the Stavropol Territory.

Keywords: reclamation of land, deflation, erosion, desertification, soil compaction, biometrics.


QUESTIONS AGROECOLOGY

Change of soil functional properties in Astrakhan region in modern ecological conditions

In given clause the basic results of researches on toxic influence of oil on zone soil types of Astrakhan region are resulted. The basic changes of physical and chemical parameters of soil are studied.

Keywords: oil pollution, soil types, hydrocarbons, physical and chemical properties of soil.


Agroecological monitoring of the maintenance of mercury in soils of Yaroslavl region

Mercury monitoring in soils, snow, rain water, ground waters of Yaroslavl region is presented and the estimation of its maintenance vegetative production is given.

Keywords: monitoring, mercury, heavy metals, admissible level, maximum permissible concentration, background.


Modern problems of ecological balance preservation at natural pasture lands in North Caspian regions

High level of the anthropogenic pressure on ecosystems results in it all over degradation. It brings to research of plant anthropogenic dynamic of primary importance. Pasture animal farming was found to be main source of negative ecological influences on agriculture and overgrazing was found to be main threat to arid lands. Intensification level of modern pasture animal farming should correspond to as natural as social-economic conditions of concrete area. First of all it is necessary to take into consideration bioproductivity of natural pastures and risks of irreversible degradation transformations.

Keywords: ecological balance, natural pastures, desertification, degradation, desert associations, pasture pressures.


Application of biological wastes of agriculture as organic fertilizers

Biological waste application of agricultural production as organic fertilizer is of great importance for practical workers. It is shown that the compost made of on the mushroom compost technology is the most effective biological fertilizer. The use of straw as fertilizer is unreasonable.

Keywords: crop rotation, straw, chicken manure, compost, humus degeneration, root rottenness.


YOUNG SCIENTISTS INVESTIGATIONS

Use of natural sorbents and it’s mixtures fir immobilization of arsenic in contaminated soil

Results of researches of natural sorbents, their mixes and updatings on an arsenic immobilization in the polluted soils are resulted. A number of decrease of mobile forms of arsenic in soil under the influence of natural sorbents and their updatings is made. Laboratory, vegetative and лизиметрические experiences have shown that the diatomite processed Fe3+, in a mix in the best way connects arsenic with blue clay.

Keywords: sorbent, detoxication, arsenic, diatomite, iron, blue clay, sapropel, calcium carbonate.


Effect of agrochemical properties of soil on return of nitrogen fertilizers yield increase

The influence of complex agrochemical soil properties on the efficiency of nitrogen fertilizers to be made under a spring barley on sod-podzolic and gray forest soils of the Central Non-Chernozem zone. Established that the return of nitrogen fertilizer increase of crop of spring barley increased with increasing the content of mobile forms of phosphorus and potassium, and reduce soil acidity.

Keywords: agro-chemical properties of soil, nitrogen fertilizers, payback.


Modern humiс condition of steppe chernozem soils of Transbaikal region

There is assessed the modern humic condition of chernozems and agrochernozems of the Tugnui hollow of Transbaikal region in the article. There is also shown the change of qualitative structure of humus in the course of agricultural use of soils.

Keywords: humic structure, humic condition, chernozem, agrochernozem.


Agrochemical and microbiological particularities of artificial soil (constructozem) in Moscow and Moscow region towns

Agrochemical and microbiological features of a representative set of urban constructed soils (laminated urban soils) (n =61) have been analyzed in comparison to zonal non-urban soil cover (n = 30). The difference between urban and non-urban soils was significant, despite high spatial variability. This enabled to formulate the main tendencies of soil cover transformation, resulting from land conversion into urban land-use.

Keywords: agrochemical features, microbial biomass, microbial respiration, soil organic carbon, urbanization, urban constructed soils, zonal non-urban soils.
