06.00.00 Agricultural sciences
Description
Main normative demands, accepted by Gosstandard to assess soil contamination with heavy metals are casted in the article. Degree of mobility of studied heavy metals for leached chernozem of Krasnodar region was computed by the author. The author recommends to use information technologies under soil-ecological assessment and makes an example of calculation of dependence of manganese mobile forms content on humus and iron dynamics change in software environment statistica 6.0.

THE MATHEMATICAL MODEL OF ECOLOGICAL SITUATION ON THE RICE IRRIGATION SYSTEM
06.00.00 Agricultural sciences
Description
Solving of problems of the influence of irrigation on ecological situation and creation of optimum land-reclamation conditions are impassible without using of the mathematical modeling methods. The work provides the idea of solving of the land-reclamations problems with the using of systematic-cognitive analysis.

Description
As for beneficial fauna, the most number of parasitic hymenoptera is noticed in organic orchards. The least quantity of parasitic hymenoptera can be met in conventional orchards. The characteristic feature of arthropods in conventional orchards in 2008 was the frequent occurrence and rather big number of acariphages (ladybirds of Stethorus family). The occurrence of the considerable quantity of predatory bug Campilomma and the bugs of Orius family was registered. All the enumerated species attack phytophagous mites. With the assumption of phytophagous mites population increase in organic orchards, the increase in Stetorus specimen was registered. Acariphages in ecological orchards occurred rarely. So we can suggest that predacious insect species – Stetorus, Campilomma, Orius –can serve as a certain indicator showing one or another population density of phytophagous mites in apple-tree orchards.

ECOLOGICAL CONDITION OF IRIKLINSKY WATER STORAGE BASIN. ASSESSMENT OF FISH CATCH FOR THE LAST DECADE
Description
Brief physical-geographical, hydrological, hydrochemical and hydrobiological characteristics of Iriklinsky water storage basin, the largest water storage basin on the river Ural, is given in the article. Assessment of ecological condition of the basin, ichtyofauna and fish catch in for the last decade is casted. Recommendations on rational use of Iriklinsky water storage basin were given.

ECOLOGICAL AND BIOLOGICAL FEATURES OF GROWING OF OWN-ROOT PLANTING MATERIAL OF FEIJOA
Description
The results of breeding of lignified cuttings of varieties and forms of Feijoa in the humid subtropical of Russia are presented. Lignified cuttings cut from the top and bottom were covered with uterine of root-own plant varieties of "Superba", "8-10""0-01"and "D-1" and placed on the beds with different substrates: tea soil; peat + sand, perlite. It is established, that the lignified cuttings from the bottom of the overgrown Feijoa variety “Superba” were better rooted in the "tea soil," from the top of the shoots - on the substrate peat + sand. Lignified cuttings of all forms and types of plants studied rooted worse in perlite
