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 micronut ...

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 applic ...

There are given the results of long-term research of different forms of soil nitrogen content and their relationships with the content of total nitrogen in leaves and yield. It was detected a strong positive correlation among them hydrolyzable nitrogen content in the soil and total nitrogen content in the leaves and yield. It is proposed the use of this index for diagnostic of soil nitrogen supply

The problem of environmental safety of agricultural products and agro-technical measures is very urgent now. Various agrochemicals are widely used in agricultural production: plant protection preparations, fertilizers, stimulants and plant growth regulators, etc. One possible solution of this problem may be a partial replacement of mineral fertilizers by bacterial ones. The aim of our research ...

This article presents the experimental material obtained from long-term stationary experiment of GNU "Severokubanskaya agricultural experimental station" in P.P. Lukyanenko Krasnodar Agricultural Research Institute. Stationary experience was founded in 1978. It had two ten-course crop rotations and combined graingrass tilled. The ordinary black soil, low-humic, heavy loamy in mechanical compos ...

The article deals with the effectiveness of mineral and organic fertilizers in long-term application (for more than thirty years) according to the influence on the fertility of ordinary black soil of the Western Ciscaucasia and productivity of sugar beet. The investigations were carried out in the long-term stationary experiment laid on the experimental stationary section "Severokubanskaya agr ...

The article presents three-year data on the influence of different fertilization systems and predecessors (corn for silage and peas) of winter wheat in the rotation on the dynamics of content in the 0-20 cm layer of black leached soil of mineral nitrogen, of available phosphorus, of potassium, and yield of winter wheat. The materials presented in this article indicate that, regardless of its p ...

The basic amount of oilseeds in the Russian Federation, including the Stavropol region is produced by sunflowers. Using the best ways and methods of soil cultivation and improving the technology of sunflower cultivation in relation to specific growing conditions - the main way to increase the yield and gross yield of seeds of this valuable crop

The article discusses the various technologies of cultivation of winter barley at two ways of main tillage (recommended and zero-level) with different backgrounds of soil fertility, fertilization rates, protection from weeds, pests and diseases. Consistent improvement of soil fertility and other fertilizers resulted in an increase in crop productivity. Nutrition is the basis of life of a livin ...
