Optimization of agricultural system planning
The resolution of a complex agriculture optimization is studied. The software system is offered that allows entering the information about a field and a particular technical task, and processing optimal system design in accordance with the entered information.
Keywords: farm plots, soil types, cultivation technologies, agricultural crops, components, marks for the components, signals for the marks, rules.
Biogeocoenosis ecological rate setting problems
The methods allowing soil to show stability to any influences, including their pollution by various toxicants are considered.
Keywords: soil, biocoenosis, pollution, rate setting methods, fertilizer system, heavy metals, plants.
PROPERTIES AND PRODUCTIVITY OF SOIL
Studying of hydrophilic properties of sod-podzolic soil during long-time application of fertilizers
Influence of various systems of fertilizer on soil hydrophilic properties is considered. It is established that the greatest positive effect is achieved by using of organic-mineral fertilizer systems.
Keywords: soil hydrophilic properties, fertilizers, swelling capacity and speed, organic matter.
Dynamic of agrochemical parameters of burozem soil during water erosion
The accelerated development of water erosion, provoked weather conditions, results in decrease of parameters of fertility for a short time intervals, that is reflected in productivity of agricultural crops. The speed of change of properties soils in conditions hilly agricultural landscape depends on an element of a relief.
Keywords: intensity of erosion, geomorphologic conditions, agrochemical parameters, microelements, nitrates, winter rye.
Ecological condition of gray forest soil agrocoenosis
In the conditions of prolonged stationary test influence of various doses of mineral and organic fertilizers on biological indicators of Vladimir opolye grey forest soil which reliably reflect intensity and direction changes of microbiological and biochemical processes against the agrobackground of various intensification is investigated. It is established that untouched soil biotope have biological activity indicators above than the grey forest soils subject to agrogene load. High-intensity mineral background is a variant in which there were the greatest negative deviations from natural analogues.
Keywords: soil, microbial coenosis, ecosystem, agrobackground, indicators, processes, appraisal.
Influence of growing dozes of sewage sludge on some parameters of soil during fertilizing of cereals
The results of researches have shown, that the application of sewage sludge in dozes 30-90 t/ha under cereals has increased productivity of winter wheat and oats on 4-32 of%. Their large efficiency is marked in afteraction (oats). Physicochemical properties of soil and the contents of mobile potassium at single application sewage sludge has not changed, the contents of phosphorus grew with increase of a doze, the security by mineral nitrogen raised only per year of application. Increase MPC levels of the contents heavy metals in soil and grain was revealed not. Use sewage sludge has increased nitrifying activity of soil, allocation СО2 and the processes of cellulose destruction.
Keywords: sewage sludge, productivity, fertilizer, soil, heavy metals, cereals.
Microelements and heavy metals content dynamic in soil in Chuvash republic
There are cited the results of the investigations of the microelements’ and heavy metals’ dynamics in the soil of the repernyi strips, situated in diverse climatic conditions of the Chuvash Republic.
Keywords: soil, repernyi strips, microelements, heavy metals, fertility, climatic zones.
NEW PREPARATIONS AND MICROFERTILIZERS
Efficiency of microfertilizers application in the Nizhniy Novgorod region
In this article the short analysis of soils of the Nizhniy Novgorod region security by microelements is given and results of the various preparations containing microelements tests are presented.
Keywords: microelements, soil, microfertilizers tests, efficacy
Influence of Micromack preparation on organic matter and microbiological parameters of soil
А positive influence of the new combined preparation Micromack, used for pre-sowing seed treatment in combination with mineral fertilizers, on organic matter content, numbers of basic groups of soil microorganisms and the yield of spring wheat was established.
Keywords: soil, Micromack, Baikal, mineral fertilizers, organic matter, microorganisms, spring wheat.
Application of bacterial fertilizers in dry farming conditions in pre-Caspian area
Results of long-term tests of bacterial fertilizers are resulted. It is established that the yield of spring wheat essentially varied in dependence both on a grade, and on processing.
Keywords: ecological conditions, soil, yield, bacterial fertilizers, crop.
Chemical melioration of soil with application of composite agrochemical based on carbon structure
Possibility of composit agrochemical use as a ameliorant is considered. Results of the model and field experiments indicating its efficiency by land with low fertility of soils reclamation are resulted.
Keywords: fertilizer, ameliorant, microelements, soil, experiment, tomato, carrot, productivity.
INVESTIGATIONS OF SCIENTIFIC-RESEARCH INSTITUTE FOR AGRICULTURE OF NON-CHERNOZEM ZONE
Natural and arable land conditions for grain production
Biological productivity of plants, which consists of natural and economic fertility and soil properties created by human activity, is studied.
Keywords: soil, appraisal, humus, pH, phosphorous, potassium, water and temperature regime.
Influence of cultivation technology of grain crops from All-Russian scientific-research institute for agriculture of non-chernozem regions breeding on quality of harvest
The three-year researches spent on 6 cultures, 18 grades which have been grown up on 3 technologies, have shown that the nitrogen, phosphorus and potassium content in an initial phase of plants development considerably above, than in a stage of full ripeness. The nitrogen, phosphorus and potassium content in plants to a considerable degree depends on quantity of brought doses of fertilizers and biological features of a grade.
Keywords: technology, new varieties, soil, fertility, yield, grain crops.
Spring wheat crop formation by modern technologies
A number of processing methods is studied and elements of high-quality agrotechnology are developed for perspective grades of spring wheat.
Keywords: technology, variety, soil cultivation system, fertilizing system, plant protection, harvest.
