Description
The article presents the results of the studies of the processing effect of the growth regulator called Stimolante 66f (Stimolant) on cuttings of Moldova grape variety as well as on the regenerative properties, yield and quality of seedlings. We have tested three concentrations of the preparation - 0.001; 0.01 and 0.1% as compared with heteroauxin treatment (standard), and no treatment (control). The experiments have been conducted in the laboratory and in the field. In the lab experiment cuttings were rooted in the vessels with water, and in the field they were planted in open ground. Processing cuttings with heteroauxin led to a delay in blooming of the buds of 0.4 days, and with Stimolante - to acceleration of the process to 0.3-0.8 days. Processing cuttings with heteroauxin and with Stimolante at 0.01 and 0.1% had an inhibitory effect on the growth of shoots, which survived until the end of the experience. Using Stimolante at 0.01 and 0.1% resulted in a stimulation of rooting cuttings and increased the output by 3 or more roots. Heteroauxin stimulated rooting only in the initial period. More roots formed on cuttings processed by heteroauxin and Stimolante at the minimum concentration of the drug, i.e. 0.001%. In the open ground, the best results for the yield and the quality of the seedlings were obtained with concentration of 0.1% of Stimolante. Heteroauxin showed worse results than Stimolante in optimum concentrations like in the rooting of cuttings on the water as in the open ground

BIOHUMATE EFFECTS ON SOIL BIOTA
DescriptionThe article represents the results of the experiment on biohumate «Vermistar» (which was obtained by vermiculturing) and its effects on mycological soil composition. Humic preparations are interesting in the way of detoxication of soil. When humic compounds are active, herbicides and pesticide decompose faster and concentrations of heavy metals are lowered. Adding humic fertilizers affect the physical properties of water-Soil: increases capillary and light soil field capacity (an average of 20-30%) and heavy water permeability, improves the structure and its water stability, reduced soil density. It was noted, that low doses of humic fertilizer contributes to water-stable aggregates, and high - change the ratio of the structural units in favor of agronomically valuable fractions. This, in turn, is accompanied by changes in the humus state, and biological characteristics of the soil. Moreover, increased microbial activity was observed in the first year of application of fertilizers and as an aftereffect. The maximum total number of microorganisms established in the initial phases of plant development. The increase in the number of microorganisms is enhanced and the enzymatic activity of the soil which in turn increases the mobility of soil nutrients

Description
The results of a long-term research of the influence of various biologically active agents (a humic preparation Lignogumat and microbiological Baikal EM fertilizer) on a structural state and the enzymatic activity of ordinary carbonated black soil are presented. It has been established that biologically active substances contribute to increased enzymatic activity, humus and improve the soil structure

Description
Large agricultural load on the steppe landscapes leads to the transformation of ecosystems and effect on all their components. Transformation of lands into laylands leads to a gradual restoration of anthropogenically disturbed steppe ecosystems. Studies that focus on the research of comprehensive processes in the territory of laylands are extremely relevant today. Herpetobiont fauna is one of the important characteristics of ecology and biology of soils. Herpetobiont Coleoptera can serve as indicators in the study of processes occurring in postagrogenic soils.The article presents the results of the study of changes in mesofauna, composition and structure of complexes of the gerpetobiont Coleoptera of ordinary black soils in natural succession series of different-age laylands. We also evaluated the degree of faunistic similarity of plots of laylands and allocated dominant species. Carabidae and Tenebrionidae are the basis of complex Coleoptera in the investigated laylands. The article shows that such indicators as the number of individuals, species, families of beetles and their dynamic density are depended on the age of the layland. In addition, the indices of biodiversity (Margalef and Shannon) and dominance (Simpson) are also connected with the age of plots of laylands
