INFLUENCE OF COMPLEX COMPOST ON PHYSICAL PROPERTIES OF SOIL
DescriptionComplicated compost is used for recultivation of soils and represents a new direction in practical husbandry and ecology defining the artificial creation of complex mixtures of different wastes of industrial and agricul-tural production, as well as household residues and natural materials for the enrichment of organic and mineral dispersed and colloidal systems with purpose to improving their physical, chemical, biological and ecological functions

SPECIES DIVERSITY OF LONG GOURD LAGENARIA SICERARIA (MOLINA) STANDL
DescriptionThe issues of international spread of fruits of long gourd lagenaria and the introduction of it in culture are considered in the article. We have shown how to use it as a vegetable crop and considered varietal diversity of this species. The biological characteristics of lagenaria cultivation as vegetable plants, including peculiarities of the reproductive system have been marked. We have also considered the issues of cultivation and distribution of long gourd lagenaria (zycca) for food

OVERREGULATION OF OVERFLOWS OF PLAIN KRASNODAR TERRITORY
DescriptionSurface sewer depends on vegetable cover. Deleting the vegetable cover (due to cutting, overindulgent fall out live-stock, fires), wrong plowing up of surfaces (along declivity) and processing of ground without observance agronomic rules bring reinforcement of erosions, local soil washout, origin gully erosions and to increase the turbidities of the rivers

QUESTIONS OF PROTECTION OF SOIL IN THE AGROLANDSCAPES
DescriptionBalance of heavy metals in the topsoil describes their content at admission and take-out for a specific period of time. Sources of heavy metals in the soil are their admission with atmospheric precipitation, sowing material, dust, organic and mineral fertilizers, as well as other components. Take-out of elements from the soil is taken into account with a crop (grain yield of green mass, roots, etc.), as well as with the removal of water and wind erosion

Description
Application of a factorial method for determining the needs in metabolic protein and essential amino acids, helps to deepen knowledge on physiology of protein and amino acid supply and allow to improve the standards for dairy cows during the transition period; in insufficient of metabolic protein and essential amino acids increased coefficients of their transformation into net protein and absorptive amino acids as a result of mobilization of body of cows; with an optimal protein nutrition their transformation in net milk protein, lysine and methionine accordingly amounted to 0.67, 0,83 and 0,82. The most significant changes in the concentration of methionine, proline, glutamate, glutamine, glycine were observed in cows before calving and immediately after birth, stabilization of their level starts with a 24 lactation day, that is connected with the peculiarities of the feeding behavior of the cows and the gradual intensification of the processes of metabolism and milk production. To control the status of protein metabolism we have offered benchmarks compositions of free amino acids in cows’ blood plasma phases: 21-0 days before calving, 0-21 and 22-120 days after calving

HELIANTHEMUM DAGHESTANICUM RUPR. PECULIARITIES OF ITS DISTRIBUTION AND PHYTOCENOTIC PLACEMENT
DescriptionIn the given work there is information about peculiarities of distribution and phytocenotic placement of the endemic of Dagestan flora Helianthemum daghestanicum Rupr. Twenty five locations of the species are detected and four of them are new ones. Altitude levels of its spreading are defined more accurately – 350 – 1750 m. It is notified that basic types of vegetation, where Sunrose Dagestanian can be met, are communities of mountainous xerophytes and mountain steppes with domination of Botriochloa ischaemum and Salvia canescens
