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.

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.

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.

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.

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 20^th 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.

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.
