Condition and dynamic of arable soil fertility in Yaroslavl region

The analysis of the basic agrochemical indicators of arable soils in Yaroslavl region since 1990 and their dynamics over the last 10 years is given. Acidification of arable grounds is observed, 50% has the insufficient maintenance of mobile phosphorous, more than 70% of exchange potassium, more than 60% has low humus content (to 2,5%). It is necessary to increase the areas of liming of sour soils, volumes of application of fertilizers.

Keywords: agrochemical inspection, dynamics, acidity, nutritious elements, fertilizers, fertility.


Chrome and nickel in soils in Belgorod region

The paper presents the results of agroecological monitoring, characterizing the total content and concentration of mobile forms of chrome and nickel in arable soils of the Belgorod region. Analyzed the distribution patterns of these elements by layers of the soil profile.

Keywords: monitoring, chromium, nickel, chernozem, toxicity, total content, the content of mobile forms.


Vanadium in sod-podzolic soils in Kaliningrad region

Laws of accumulation of mobile connections of vanadium in humus-accumulative horizons are established. Data on a content of mobile vanadium in sod-podzolic soils are presented. The major factors defining a content of mobile vanadium are the water-air mode and a content of organic substance.

Keywords: vanadium, mobile connection, soil, granulometric composition, humus, acid-base properties, red-ox potential.


Ecological-toxicological appraisal of arable soils conditions in Republic of Kalmykia

Given the results of the weighted average content of gross forms of heavy metals, arsenic and fluorine, ecological and toxicological grouping of soils and ecological-toxicological assessment of condition of soil arable horizon of arable land. Established that average concentration of heavy metals (lead, cadmium, zinc, mercury, chromium, copper, manganese) in all types (subtypes) of soil in arable layer of loamy granulometric composition lower than background level except arsenic, nickel and mobile fluorine, which are exceed background level, but lower than limited permissible concentration. Therefore plant production harvested at these territories is safety.

Keywords: heavy metals, arsenic, active fluorine, loamy and sandy-loam soils, ecological-toxicological appraisal, coefficient of danger, concentration ratio, the total parameter of pollution.


FERTILIZER AND HARVEST

Appraisal of mineral fertilizers and liming influence on chemical composition of agricultural crops and nutrients balance in soils in Krasnoyarsk region

Mineral fertilizers effect selectively the concentration of nutrition elements in cultivating crops on sod-podzolic soils. Application of 435 kg of nitrogen, 360 kg of phosphorus and 360 kg of potassium in 1 hectare of rotation square provides negative balance of nitrogen, lightly negative balance of potassium and positive one of phosphorus. Reservation of cereals' straw on the field (50% of rotation fields) provides lightly negative balance of nitrogen, positive of phosphorus and potassium. Liming leads to some reduction of balance intensity for all elements.

Keywords: sod-podzolic soil, fertilizers, liming, plants chemical composition, nutrient balance.


Barley consumption of nutrition from different layers of sod-podzolic soil

This article is devoted the study of the use by barley nutrition from different horizons of sod-podzolic soil. The purpose of research is in definition of availability to plants macroelements has important meaning as in theoretical and practical aspects.

Keywords: barley, nutrition elements, soil layers.


Efficiency of calciumcontaining fertilizers varieties on rice fields of Kuban region

There are given the foundings on calcium containing fertilizers varieties. There has been revealed the advantage of phosphogypsum application on meadow chernozem soils in rice crop rotations. There are given some recommendations for rice cultivation.

Keywords: calciumcontaining fertilizers, experiments, rice fields, yield.


Influence of soft spring wheat cultivation technologies on grain quality

Results of research of spring wheat cultivation technological operations in Non-chernozem zone of Russia are presented. Elements of variety agrotechnique are elaborated for harvesting of programmed yield.

Keywords: cultivation technology, spring, wheat, varieties, yield.


Research of dozes and types of early-spring top-dressing of winter wheat atcommon chernozem soil

According to the 3 years research results in arid zone on ordinary chernozem soil it was found that studied methods of nitrogen top-dressing didn’t have any significant effect on the yield of winter wheat, and the advantage of the top-dressing method is not significant in compare with the tops way of application in early spring feeding. In compare with control difference resulted in 0,3-0,7 t/ha for Esaul variety and 0,3-0,8 t/ha for Nota variety.

Keywords: early-spring top-dressing, way of application, doze of fertilizer, chernozem, winter wheat.


HISTORY OF RESEARCH

Influence of 100 year permanent plant growth on the agrochemical properties of sod-podzolic soils

In Geoseti Russia operates a number of multiple stationary experiments. Among them are the longest – the experience, founded 100 years ago, Professor. A.G. Doyarenko on the former experimental field of the Moscow Agricultural Institute (now RGAU-MAA them. Timiryazev). Informative and depth of the research, their agronomic value and impact of this experience is unique not only to Russia, but also in world science. 100 years - enough for a significant period of multifactorial field experiment, and summary information on key indicators of fertility change at different levels of intensification of practical interest for agricultural production.

Keywords: long-term experience, humus, mobile phosphorus, exchangeable potassium, acidity, fertility, agrochemical score.


Main results of long-term field experiment (from 1931) founded by D.N. Pryanishnikov at Dolgoprudny agrochemical experimental station

Presentation of main results of long-term field experiment founded by D.N. Pryanishnikov in 1931 at Dolgoprudny agrochemical experimental station in four field crop rotation with clover fallow on typical for Central Non-chernozem heavy loamy sod-podzolic soil. According to data of annual crop rotation productivity during 19 rotations and aftereffect in 20th rotation organic and mineral systems of fertilizers are equivalent. Long-term positive effect of periodical liming on fertility of acid soil is established. Characteristic of fertilizing systems influence on humus content, quality of organic matter, acid-base balance, concentration of available phosphorous and potassium forms during whole period of experiment is given.

Keywords: long-term field experiment, research results, soil fertility.


AGROECOLOGY: PROBLEMS AND SOLUTIONS

Natural and technogenic radionuclides in soils at Plavsk radioactive spot in Tula region

The modern radiating background of the Plavsk radioactive spot in Tula region is formed at the expense of natural (40К, 232Th, 226Ra) and technogenic radionuclides (137Cs). Thus the share 137Cs from the general stocks of radionuclides in soils makes 48-67%, and as a part of vegetative production – only 5-14% that reveals insignificant parameters of transition of an element from soils in plants.

Keywords: radionuclide, contamination of soil, migration in «soil-plant» system.


Questions and tasks of production and storage of liquid manure

The article shows the problems of the use of liquid manure in the farms of the country. The prospective directions of development of technologies and technical means of production and storage of semi-liquid, liquid manure, dung and livestock wastes.

Keywords: manure, dung, livestock wastes, production, storage, perspective technologies, technical means.
