The physical-chemical properties of the dark gray forest and chernozem soils oа Nizhniy Novgorod region

The physicochemical properties of the dark gray forest and chernozem soils of Nizhniy Novgorod region were examined on the basis of data of agroecological monitoring, the analysis of their dynamics was carried out. It was established that on the background of favorable characteristics, caused by the genetic special features of soils, the tendencies of worsening in the physical chemistry indices were observed.

Keywords: physical-chemical properties, dark gray forest soils, chernozem, acidity, absorption capacity, base saturation degree, dynamics.

Research of grey forest fallow soil in Krasnoyarsk region

Did not note reduction in the fertility of gray soils, on a number of soil-agrochemical indices and biological activity, with the overgrowing the young forest of different breeds of trees of deposits.

Keywords: fallow land, afforestation of fallow land, gray forest soils, spatial variation of properties, microbial structure, coefficients of microbiological mineralization, enzyme activity.

Phosphorous conditions of grey forest soil in crop rotation with lupine

There has been studied the effect of green manure of lupine and its root-crop residues on stocks and transformation of phosphorus compounds, as well as the productivity of crop rotations on grey forest soil in the stationary field experiment.

Keywords: availability of phosphorous, transformation, grey forest soils, crop rotation, lupine, root system.

Fractional content of mobile lead and zinc compounds in sod-podzolic soil

For more detail characteristic of heavy metals toxicity and availability to plants it’s necessary to fractionate heavy metals. This analysis allows to estimate amount of water-soluble forms, form related to calcium carbonate, manganese oxide and organic matter. As result of our research established that mobile form of lead in soil are related to organic-mineral complex and mobile compounds of zinc are evenly distributed by fractions.

Keywords: fractional content, toxicity of chemical elements, pollution, extraction agent, soil.

Influence of landscape on formation of forage crops and potato chemical content

Formation of soil chemical content at different nature-territorial complexes and also forage crops and potato at different landscape conditions of moraine hill are investigated. Correlations of chemical content of plants and soil, which can be used for elaboration of adaptive fertilizing system, are shown.

Keywords: landscape conditions, chemical content of plants and soils.


Efficiency of fractional application of fertilizers for winter barley cultivation

The greatest productivity of different grades of winter barley on ordinary chernozem is achieved at quadruple application of mineral fertilizers. Nitric dressing strengthened effect from the fertilizers brought in the previous terms.

Keywords: nitrogen, phosphorous and potassium fertilizers, fractional application, hibernation, productive stalks.

Research of new barley sorts nutrition conditions

There was revealed the reaction of new sorts of barley on the intensity of the fertilizer, soil and weather conditions on sod-podzolic medium-loamy ground in conditions of lysimetric permanent establishment. There have been established the migration’ losses of biofill ground elements and their consumption by plants.

Keywords: mineral fertilizers, new sorts, barley, fertility, migration, biofill elements.

The features of olive flax formation efficiency at different level

There was offered the researches’ analysis of influence of terms of crops and level of a mineral food on efficiency of flax of an olive grade Sanlin. It was found out that the variant N90Р60К60 with the norm of seeding – 8 million piece/ha (21,5 с/ha) has appeared the most productive, and application of fertilizers in any investigated doses promoted flax’s crop to increase to the control.

Keywords: olive flax, fertilizers, norm of seeding, yield, oil seeds.

Appraisal of fertilizing systems, nutrients and humus balances at crop rotations of adaptive-landscape agriculture

Presentation of nutrients and humus balances during 10 year application of fertilizers at grey forest soil in Vladimir region. Low doze of the mineral fertilizers and use of manure at grain-grass crop rotation provide 22,3-25,0 c/ha productivity, negative or zero balance of phosphorous, positive balance of potassium and deficit-free balance of humus. Middle and high doze of the mineral fertilizers at the same crop rotations don’t provide planning yield level and result accumulation of phosphorous and potassium in soil.

Keywords: fertilizers, balance, nutrients, soil, crop rotation, fertilizing system, appraisal.

Research of nitrates accumulation in green mass of perennial grasses

Twice application of the nitrogen fertilizers N30 at flood lands eliminates possibility of nitrates accumulation in green mass of perennial grasses higher MPC.

Keywords: nitrates, green mass, perennial grasses, flood lands, nitrogen fertilizers, vegetation conditions.


Study of the sod-podzolic soil’ characteristics and plants’ chemical composition in a long-term field experiment

There has been carried out estimation and generalization of the unique experiments’ results of Dolgoprudnaya agrochemical experimental station, which had been installed by D.N. Pryanishnikov in 1928-1932 and are in the present moment under the threat of closure.

Keywords: sod-podzolic soil characteristics, fertilizers, productivity, harvest, long-term field experiment.

Drop irrigation and nutrition of carrot

Drop irrigation in combination with application of correct dozes of the mineral fertilizers at light chestnut soil of Low Volga river regions allows to harvest 70 t/ha of high quality carrot.

Keywords: drop irrigation, fertilizer, carrot, yield, quality of root crops.


Quantitative regularities of imidacloprid sorption by soils

The sorption of imidacloprid by four soil types of the Russian Federation was studied. The sorption was approximated by the line isotherms. There was a direct correlation between sorption and soil organic matter content. The soil pH did not influence to sorption of imidacloprid. The desorption profile of imidacloprid proclaims about chemical sorption mechanism of pesticide sorption by soil.

Keywords: sorption, insecticide, soil, imidacloprid.

Derivative-graphical method of humus condition of sod-podzolic sandy-loam soil researches

There was carried out the researches of the influence of mineral, organic and organic-mineral fertilizing systems on thermal indicators of sod-podzolic soil through the studies of quantitative and qualitative indicators of the organic matter. There was revealed the efficiency of organic and organic-mineral fertilizing systems according to their influence on the total amount of the soil’ organic matter. The quantity of the labile organic matter increased due to the prolonged use of the higher doses of mineral fertilizers, still its bond strength with the soil’ mineral part was falling.

Keywords: soil, organic matter, methods of research, fertilizing system.
