TO THE QUESTION OF FORMATION OF A BUSH OF THE FESCUE MEADOW
Description
Ecological factors have a great impact on transition of a fescue meadow to formation of a bush. The optimum mode develops at high daily temperatures, in the rarefied crops, at security with nitrogen and without salinization

COMPLEX COMPOST AND DETOXICATION OF AGROLANDSCAPE SYSTEMS
Description
Toxicity complex compost arises during compiling of organomineral mixtures of various waste of life, agriculture and mineral industries. One of detoxification factors of complex compost is the ability of heavy metal cations to the formation insoluble compounds, which are fixed by clay materials and different disperse systems, and differ markedly by calcium content, acidity and humus soil-absorbing complex

COMPLEX COMPOST AND CIRCULATION OF NITROGEN AND CARBON AT THE AGROLANDSCAPE SYSTEMS
Description
Complex compost includes all elements of the periodic table and is valuable due to the complexity of its system. Among the elements forming a chemical composition of the complex compost we can identify two most important, which are distinguishing a specific character of the interaction with each other and defining the basic processes to ensure vegetation of living system - nitrogen and carbon. Nitrogen determines the rate of energy and connects with living forms of organic matter; it is included as the part of protein and is a major element in determining the productivity of ecosystems. At the cycle of carbon its organic forms and carbon dioxide take a part, presenting the main factors of the processes of respiration and photosynthesis

BIOLOGICAL VALUE OF PLANT PROTEIN AND VITAMIN SUPPLEMENTS
Description
Results of the use of plant protein feed additives containing pumpkin paste and soybean seeds of different varieties for quail are presented in the article. It was established that the use of such additives on the basis of Valens soybean allowed to receive higher growth parameters than groups treated with Vilan soybean additive

EFFECT OF GERMINATION OF THE CHEMICAL COMPOSITION AND ANTINUTRIENTS CONTENT IN SOYBEAN SEEDS
Description
It was established that water absorption of soybean seeds does not depend on the variety. And in the beginning it has an active character, providing the increase in mass of seeds on 80-140% after 12-14 hours. Subsequently, hydration intensity decreases and mass reaches 110-160% of the original. Electroactivated water increases the level of hydration in comparison with tap water (anolyte – 10-18%, catholyte – 5-9%). Furthermore, in the process of germination of soybean protein content increased by 4-12% and fat – 7-16%. Inhibitor content thus decreases by the same amount, and does not depend on the variety. Thus, consideration of the varietal characteristics of soybean seeds during germination allows how to reduce energy consumption for processing and to reduce the degree of destruction of nutrients
