Experience in use of modern relational databases for creation of unified repository of attribute and spatial information results agrochemical survey

The use of modern relational database management systems (DBMS) allows you to organize unified store spatial and attribute information of the results of agrochemical examination. This approach significantly reduces the cost and complexity when mass production of agrochimexport farmland and thematic maps. Description of some technical details on loading spatial data in a relational DBMS and organization of the user interface.

Keywords: software, database, spatial data, a single repository, agrochemical survey.

Influence of peat on biological features of soils contaminated by heavy metals

There is being suggested the estimation of microbial communities in soils, polluted by heavy metals. There is shown a positive influence of peat application to microbial communities of these soils. There is no symbiosis between plants and fungus Glomus intraradices in these soils.

Keywords: soil, heavy metals, soil microorganisms, peat, symbiosis, Glomus intraradices.

Aftereffect of hard coal ash on microbiolog- ical and enzymatic activity of soil

The paper is devoted to explaining the successive effect of ameliorative hard coal ash doses on the number of microorganisms and the activity of soil enzymes. The research was based on a field experiment started in 1984. The evaluation of the successive effect of the ashes on microbiological activity of the soil was performed 21 years after establishing the experiment, on three dates – in July, August and September. Fertilising with ash had a negative impact on microorganisms as, even after 21 years since the application of the ashes, the ratio of the combined number of bacteria and Actinobacteria to fungi was reduced. The successive impact of ameliorative doses of hard coal ashes reduced the activity of dehydrogenases, acid phosphatase and alkaline phosphatase, while it increased the activity of urease.

Keywords: hard coal ash, soil, microbiological activity, enzymes.

Influence of sugar production wastes on sod-podzolic soil fertility at potato cultivation

Results of sugar production waste (defecate) and it compatibility with mineral fertilizers influence on sod-podzolic soil in Moscow region for potato growing are presented. Established that defecate use for cultivated sod-podzolic soil has optimized it physical-chemical properties, has increased pH_KCl from 5,8 till 6,3, has led to decrease of hydrolityc acidity from 2,10 till 1,62 mg-eq/100 g of soil and to increase of soil basement saturation from 92,3 till 95,6%, it also has increased content of exchangeable basements till 33,15 mg-eq/100 g of soil. All these factors provided increase of potato varieties Bryanskiy and Udacha harvest and quality.

Keywords: sod-podzolic soil, defecate, fertility, potato harvest.

Gaseous nitrogen losses and soil breathe dynamics at different layers of leached chernozem

Problem of nitrogen saving in soil during nitrogen fertilizers use is researched, volume and structure of gaseous nitrogen losses from leached chernozem soil and fertilizers is researched. This will find way to decrease nitrogen losses and increase the availability of plant nutrition elements.

Keywords: leached chernozem, soil nitrogen, nitrogen from fertilizer, soil «breath».
