ACTUAL THEME

Methodology of soils’ quality estimation in thr land price policy of the region

There has been worked out a new land’ estimation procedure taking into account soils’ quality for determination of land’ prices in the region based on Russian environment protection’ law in force. The methodology is based on the conversion of ecological rent, which the society and the owner of land receive from high-quality soils, into the equalizing cost of land plots.

Keywords: economics of natural resources, estimation of land, protection of soils, ecological risks.


SOIL PROPERTIES AND FERTILITY

Some indicators of biological activity in acid brown forest soils of tea plantation of russian subtropics

There has been studied the activity of ferments of urease, catalase and phosphatase and cellulose’ decomposition in soil of tea plantation under the influence of mineral fertilizers. There has been established the seasonal dynamic of biological activity’ indicators of acid brown forest soil. It was found that application of mineral fertilizers decreased significantly the activity of catalase’ and phosphatase’ ferments. Doses of nitrogen fertilizer above 200 kg per hectare had the decreasing effect. When applying N200P60K50 urease’ activity decreased in the soil layer of 0-5 cm and increased at the depth of 5-40 cm.

Keywords: acid brown forest soils, tea plantation, soil ferment activity, application of mineral fertilizers.


Change of phosphate regime of medium loamy sod-podzolic soil during application of the phosphorous fertilizers of high dozes

There are being discussed the results of a rapid cultivation of medium loamy sod-podzolic genetically homogeneous soil with high initial phosphate level (1000 и 2000 Р2О5 kg/hectare) in the article. There have been determined the dependences of available phosphor’ content from the quantity of the applied phosphor fertilizer. There have been calculated annual doses of mineral phosphor necessary for the maintenance of the level of the created backgrounds in the time of their experiments.

Keywords: availability, aftereffect, balance, specific index of phosphate’ consumption.


Agroecological estimation ot heavy metals’ content in leached chrrnozem while a prolonged application of fertilizers

There are given the findings concerning heavy metals’ content in leached chernozem while a prolonged application of fertilizers in the article. It has been established that mineral fertilizers can not be treated as a source of pollution of soil with heavy metals. The accumulation of heavy metals in soil exceeding the MPC will be reached only in several thousand years even when triple doses of fertilizers are applied. It will take 65715 years for cadmium and 887333,3 for lead. There has been established a close correlative connection between cobalt’, manganese’ and lead’ content which has linear as well as nonlinear dependences. Increase of humus’ and acid-soluble forms of iron’ content in soil favours binding of heavy metals in difficult of access for plants organo-mineral complexes.

Keywords: heavy metals, leached chernozem, pollution, ecological safety, transformation, mineral fertilizers, ballast, accumulation, mathematic modeling.


Influence of different factors on concentration of toxic elements in leached chernozem soil

Application of mineral and organic fertilizers don’t pollute arable layer of leached chernozem soil by lead and cadmium compounds, but lead to increase of cadmium mobility in soil and accumulation in cultivation green production.

Keywords: mineral and organic fertilizers, soil factors, lead, cadmium, winter wheat.


AGROCHEMICAL SERVICE

Agrochemical service of Tatarstan republic is on the watch

Presentation of Agrochemical service role in Tatarstan republic from it’s formation in 1964 for preservation and increase of soil fertility.

Keywords: agrochemical parameters of soil, soil fertility, organic and mineral fertilizers, lime and phosphorous application.


Cooperation of an institute and agrochemical service in Khakassia Republic

There is showed the cooperation of two organizations in the field of training of agronomy staff in Khakassia Republic in the article. Taking part in the field study students gain certain professional skills and become co-executors of programs.

Keywords: training of agronomy staff, station of agrochemical service, university, field study, skills, scientific publications.


Assessment effective soil fertility

The assessment of effective soil fertility and productivity of grain crop yields, depending on the content of phosphorus, potassium, humus, soil acidity (pH kCl) and texture is well grounded.

Keywords: assessment, grain yields, soil fertility, nutzients.


Appraisal of soil fertility in Tver region in dependence of lime application

The dynamic of acidity of sod-podzolic soil in dependence of agriculture chemization intensity in Tver region and influence of lime application for support and increase of arable lands fertility are presented in article.

Keywords: sod-podzolic soil, acidity, agriculture chemization, fertility.


Change bonitet soils of the Tambov region depending on agrocoenosis

Article is devoted change bonitet soils of the Tambov region for last 40 years. The problem is considered for arable soils of the basic types and under different agrocoenosis.

Keywords: bonitet soils, agrocoenosis, soil type.


Influence of fertilizers on quality of forage grasses and hay in Murmansk region

Qualitative appraisal of forage grasses and hay based on statistic data processing including method of private lowest squares PLS (algorithm NIPALS) is presented. Size of each individual fertilizers influence on quality of grasses and hay is shown. Totally application of fertilizers lead to reliable increase of harvest and to improvement of qualitative parameters of forage grasses such as dry matter content, wet protein, wet ash, organic phosphorous and wet cellulose.

Keywords: mineral fertilizers, manure, quality of harvest, regression analysis, method of private lowest squares.


CONTINUATION OF DISCUSSION

Estimation procedure of fertilizers efficiency

Discussion after publication in issue 1-2010 article by A.V. Pukhovskiy «About method for appraisal of fertilizers and ameliorants recoupment» is presented. This theme confirms that determination of fertilizers effect incurred by private capital.

Keywords: fertilizers, cover of expenditure, rates of fertilizers application.
