The article comprises the results of two research-and-production experiments with meat poultry and pigs grown on local forages including biologically active preparations. The purpose of the research was to study the effect of enzyme preparations Cellolux-F and protosubtilin G3x and probiotic feed additive “Sporotermin” on the intensity of growth, development and metabolic processes, and conversion of rations nutrients into production. The results of the research showed that to improve the physiological and biochemical status and intensity of metabolic processes in the body, and also improving the conversion of feed nutrients into products in composition of chickens and pigs’ mixed feed one should feed the mixture of enzyme preparations Cellolux-F and protosubtilin G3x with probiotic feed additive “Sporotermin”
The condition of agrolandscape systems of Kuban has limited number of natural factors, among which an important place is occupied by temperature, moisture, nutrients and places with weediness of sown areas. Basic soils are occupied by cultivation of agricultural crops with a significant presence of segetal communities in the tilled crops, as well as field protective strips. In soils of agricultural landscapes there are actively developing bacteria, actinomycetes and microscopic fungi, the representatives of mesofauna, qualitative composition of which is very varied. When characterizing the soils we can mark a broad aspect of their contamination with heavy metals and oil, as well we pay attention to peculiarities of agriculture
The main criteria in assessing the adaptive capacity of Actinidia deliciosa (kiwi), cultivated in Russian subtropics were yield of the introduced cultivars, as well as ecological (stability and periodicity of fruiting) and biological indicators (resistance and periodicity of fruiting). The studied nature of the way Actinidia cultivars react to the constantly changing weather conditions during the period from 1998 to 2011 will help to optimize the placement of the crop in subtropical zone, and use natural resources for its unique climatic properties of Russian territory in a sustainable way
Creation of joint sowings is very complicated modern environmental problem and the solution is impossible without a comprehensive study of the relationship between individuals of different species that are emerging at the level of a plant community. Studying biotic relationships between taxa used in these crops is very important; joint crops include combinations (sowing crops in rows) and mixed crops (crop seeds mixed and sown together); great attention in the mixed and combined sowings has been paid to selection and combination of cultures
The article contains the review of the basic standards providing ecologically safe recycling of a manure at modern pig-breeding complexes with a Capacity of 12 000 and 50 000 heads of a finishers a year. The capacity of storehouses for liquid fraction is defined
As a result of stepped hybridization and multiple replicated screening, the new rice variety Lider was received. The peculiarities of the new variety is a quick growth of plants at a sprouting – tillering stage. It gives the possibility to obtain sprouts from water lower than 20-25 cm which kills for Echinochloa. Lider is grown in Russia without application of pesticides.
The proposed agro technology for the cultivation of
soft winter wheat contributes to the reproduction of
fertility of leached Chernozem of the Western
Ciscaucasia. As a result of application of fertilizers in
the arable layer of soil hydrolytic acidity decreased by
21.8%, humus content increased by 10.3%, mobile
phosphorus - by 54.8%, mineral nitrogen by 10.3%
and potassium - by 9.6% compared to the control.
Studied agricultural technology allowed to increase the
yield of winter wheat to 81.8 kg/ha and protein to 15.3
per cent, of gluten, to 27.8%. We have noticed
exceeded concentration of mobile phosphorus in the
upper soil horizon (1.5 MРС) in the cultivation of
wheat after alfalfa, which contributed to reduced grain
yield. Under conditions of prolonged application of
fertilizers and pesticides reduced the content of mobile
forms of trace elements - copper and zinc. The content
of mobile forms of Mn, Cu, Zn, Cr, Ni, Co, Pb and Cd
below the limit values of environmental and
Toxicological regulations clayey and loamy soils for
agricultural purposes. The trend of accumulation of
cadmium in the green mass of plants (~ 1.2 MPC) and
winter wheat grain up to 1.5 MPC for baby food
Ecological and silvicultural characteristics of Black (European) Alder plantations, situated in river valleys of Sochi national park are given. Regeneration nature and soil conditions of growth are adduced
From 2011 to 2015 in the laboratory conditions there
were studied the physical properties of absorbents in the
controlled environment. There was defined that in the
variant of the "soil+water" the usual colloidal mass is
formed and in variants "soil+absorbents+water" - a
mixture of soil and gel. There was determined that the
least diurnal evaporation was fixed at the use of the
mixture: soil+ preparation “Ecogel-1”. In the control
variant of the experiment the full water evaporation was
marked on 31st day after beginning of the experiment, in
the variant with the use of the absorbent Aqua Life the
whole water evaporated on 48th day, and at the use of
preparations Ecogel-1 and Ecogel-2 the duration of
evaporation of the same amount of water supply at
temperature 22-24оС and air moisture in 55-60%
continued 57-65 days. In the result of five-year
laboratory researches there was determined the
possibility of development of water-saving technology
for fruit plantations. When we used absorbents
(granules, powders) in planting process and watering
resulting the gel-like mass completely collapses the root
system of fruit plants and the operation of the system
"soil-roots-leaves" will not depend on the physical
condition of soil and environment due to water
consumption for transpiration
The results of variety-stock combination of Russian plum and cherry plum with clone stocks are cited. We will select the more productive and early fruiting va-riety- stock combinations: Globus Kuban 86. These variety – stock combinations in the age of trees – 4 years allow us to get a crop productivity of 10- 28 tg
