TO THE QUESTION OF AGROECOLOGICAL ASSESSMENT OF SOILS ON THE PRESENCE OF HEAVY METALS
06.00.00 Agricultural sciences
DescriptionMain 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.

DescriptionData on influence of macro fertilizers on dynamics of content of more deficit elements of mineral nutrition in leached chernozem on sowings of soy-beans in conditions of perennial stationary experience of the chair of agrochemisrty are casted in the article. Content of ammonium nitrogen in soil depends in great extent on nitric and phosphoric fertilizers. Content of nitric nitrogen is higher than ammonium one. High coefficients of correlation (R=0,822 0,912) speak about authentic effectiveness of applied fertilizers in the rate N60P120K20 ; N60P120 K60. Content of movable phosphates in soil under application of duplex and triplicate rates of phosphor fertilizers separately and in combination with nitric and potassic fertilizers is increased. Potassic fertilizers determine soil enrichment with metabolic potassium among three applied macro fertilizers.

LABORATORY INSTALLATION FOR SEPARATION OF SOLID IMPURITIES FROM POTATOES
06.00.00 Agricultural sciences
DescriptionExperimental-theoretical researches on separation from potatoes solid impurities in the type of hard soil clots and rocks ratable to potatoes are described in the article. Modern potato-harvesters do not always work with good quality, make great losses and damages of tubercles, especially under cultivation of potatoes on stony soils. In connection with it, the working out and the research of new working organs of potato-harvesters, capable to separate stones and other soil clots from tubercles without X-ray radiation, are the urgent tasks.

CLASSIFICATION OF TREES AND HORIZONTAL STRUCTURE OF CENOSES
06.00.00 Agricultural sciences
DescriptionProblems of influence of horizontal structure of pine-tree stands on processes of differentiation and growth of wood individuals were studied in the article. Comparative analysis showed that the maximal influence of horizontal structure of cenosis affected the condition of individuals by classification of Kraft, than their sanitary condition.

CONSTRUCTION OF BIOGROUPS OF LIGHT-CONIFEROUS AND DARK-CONIFEROUS PLANTATIONS OF TAIGA ZONE
06.00.00 Agricultural sciences
DescriptionThe author offers under studying of plantation structure to underline intermediate units between stands and growing trees under the name “ social groups”. In the result of made researches there were received some conclusions. Distributions of distances in biogroups (social groups) in great cases (50% and more) adequately are described by normal and logarithmic function. Use of statistic indexes to describe small fetches was substantiated.
