Dynamics of soil acidity during application of limy materials

There was carried out a comparative studying of ameliorants of carbonate of calcium conversion and a dolomitic flour on soil acidity. CCC when applied changed the size of рН hydrolytic acidity quicker. However, soil acidulation with CCC as a meliorant went faster as compared to a dolomitic flour.

Keywords: lime application, soil acidity, calcium carbonate conversion, dolomitic flour.

Change of agrochemical indicators of sod-podzolic soils during application of fertilizers

In field stationary experiment on the cespitose and podsolic soil in the conditions of northern part of the Non-Сhernozem zone application of the minimum doses and settlement systems of fertilizer is studied. The increase in a grain yield of a winter rye respectively 2,34 and 3,78 t/hectare, barley – 2,06 and 3,55 t/hectare, potatoes – 21,4 and 28,0 of t/hectare, green material of a vetch and oats mixture – 22,3 and 28,9 t/hectare is established. At use of systems of the fertilizers calculated on zero balance of phosphorus and negative potassium, the increase in the maintenance of their mobile forms in an arable layer of earth, insignificant - mobile phosphorus and on 1 class – exchange potassium is observed.

Keywords: soil, fertilizers, mobile phosphorus, exchange potassium, harvest.

Agrochemical state of soil fertility of lands being output from agricultural rotation inOrel region

Article represents the results of agrochemical investigation of fallow lands in the south-east natural economic area of the Orel region. It is stated that at fields output from crop rotation evident fertility deterioration can be detected. This is determined with mineralization slowing down of plant residues, nutrients migration to the deeper soil layers and erosion processes development. The soil degradation degree depends greatly on fallow land age, its fertility factors and erosion manifestation.

Keywords: lands of agricultural designation, soil, fertility, agrochemical parameters.

Agroecological soil assessment in Tuva republic

There was carried out an agroecological soil assessment in the Tuva republic in 1970-2010 years. There were established agrochemical characteristics' and bioproductivity' change trend conditioned by changes of soil formation factors and anthropogenic impact. It is shown that soil degradation is formed through degression, fertilizers dozes reduction and development of wind erosion. There was revealed the role of humus content in soil, holdings bioproductivity and the yield of cultures in soil depository capability to CO₂.

Keywords: soil fertility, monitoring, maroon soils, soil depository capability to CO₂.

Application of bentonite for winter wheat cultivation at dark chestnut soil

Bentonite application on darkchestnut soil under winter wheat has promoted to the increasing of nitrate nitrogen, mobile forms of phosphorus and potassium content, base exchange capacity and biological soil activity. An optimal dose of bentonite 7,5 t/ha is established, providing an increasing of wheat yielding on 15,1% and significant rising of protein content in grain and vegetable gel content in it.

Keywords: bentonite, dark chestnut soil, agrochemical properties, biological soil activity.

Biostimulator impact on potato yield formation and quality

There are shown the foundings on Simbiont-2 biostimulator effect on potato bulbs yield and quality cultivated in the Moscow region on sod-podzolic medium loamy soil. The preparation under analysis increased the output of finished bulbs, improved protein and starch accumulation and reduced the contents of nitrates.

Keywords: potato, growth biostimulating factor, yield, bulbs quality.

Study of plant growth regulators and microfertilizers for table root crops

Operating of chemical salts and metals complexons is studied on table root crops in the soil-climatic terms of the Nonblack zone of Russian Federation. It is shown that metals complexons stimulates a height and development of plants, promotes the productivity of vegetable cultures, improves quality of products. Cross-correlation dependence over is brought between microelements in plants and by the biochemical indexes of products.

Keywords: table root crops, yield, quality, correlation.
