INFLUENCE OF HILLY TERRAIN SLOPE ON THE VOLUME OF ROAD EARTHWORK
Description
The analytic dependence for slope correction calculation is obtained. This correction is introduced in the formula for calculating the area of earth roadbed cross-section. It allows detailing the volume of road earthwork at the design stage. The correction size depends on the slope steepness as well as cross-sectional parameters of the earth roadbed. The calculations show that the correction size is essential if ratio of slope is 25 or less

Description
The article describes the experimental investigation of the density of the gas condensates and their frac-tions in the field of high temperatures and pressures. On the basis of the experimental and theoretical da-ta has developed a new equation of state. The ob-tained generalized equation of state can be used to calculate the density of other natural hydrocarbons

ORGANIZATION OF RATIONAL USE OF BULLS IN THE MEAT CATTLE BREEDING
06.00.00 Agricultural sciences
Description
We developed an effective technology of reproduction in meat cattle breeding, which allows rational use of the bulls-producers, to obtain a high output calves (85-95%), to organize the accuracy of the account of the origin of young animals, to improve the level of selection-breeding work on the improvement of productive and breeding qualities of animals and create in a shorter time highly productive herds of meat cattle

Description
In the article, the maintenance of heavy metals in fertilizers is resulted. The quantity of the years providing ecologically safe entering of mineral fertilizers before excess of maximum-permissible concentration of heavy metals in soil is calculated. The balance of heavy metals as micro – and ultra microelements in leached black soil is resulted

Description
The article reviews the results of studying the adaptive potential of hybrids of corn maturity of different groups in the Central Caucasus. It discusses the variation of adaptive traits of maize hybrids (ecological plasticity and stability of the manifestations of agronomic traits), as well as stabilizing the yield of corn on an annual basis in the processing of seed preparation "TMTD-plus", which contains in its composition Krezatsin growth regulator

SEDIMENTS WATER SUPPLY AREAS OF FRUIT OF KRASNODAR REGION
06.00.00 Agricultural sciences
Description
We present a brief description and analysis of the weather conditions of 2005-2011 in North, Piedmont, and the Kuban Krasnodar fruit zones. In the course of many years of research, the optimal conditions for precipitation of water supply as one of the most im-portant factors in increasing the productivity of agro-phytocenoses in the region
