In the article there were given the results of researches
for 20110–2012 obtained of many years stationary
experience of the chair of general and irrigated land
management of Kuban State Agrarian University on
study of main soil treatment influence and doses of
mineral fertilizers under soy beans on dynamics of
moisture in soil and efficiency of its use by this cultivar.
There was determined that from all studied variants
the ploughing on 20–22 cm led to the higher accumulation
of moisture for autumn-winter period. The
decrease of productive moisture reserves on 6-9 % was
observed on the types with surface treatment and direct
sowing. The increase of soil treatment depth and doses
of mineral fertilizers promoted to the better accessibility
of moisture during vegetation period and correspondently
to their greater expenses. Moreover, there
was revealed the more rational use of water by soy
beans under mouldboard soil treatment and introduction
of mineral fertilizers in the dose of N90P120, it discovers
the high effectiveness of present agricultural
methods. The highest productivity of soy beans in the
experience was achieved by means of ploughing on
20–22 cm and introduction of mineral fertilizers as a
main type of soil treatment
The article presents the results of the study of
harmfulness of pink sonchus in sunflowers plantations
In the article, we present results of the research of the
influence of various processings of soil on accumulation
of productive moisture in autumn and winter periods
Results of researches on studying of various doses of
mineral fertilizers on efficiency of hybrids of sunflower
Vulcan, the Arena, the Brio and the Signal are given
in article. Researches showed that depending on formation
of biological mass of sunflower reserves of
productive moisture decreased that was a major factor
in productivity formation
There were cited the results of researches for 2010-2012 obtained in the stationary experiment of the chair of general and irrigated land management of Kuban State Agrarian University on the study of influence of the system of main soil processing under soya beans on the dynamics of main agrophysical indexes of leached black soil: on density of composition, solidity, general porosity, coefficient of structural properties in the article. There was stated that in the beginning of vegetation on the background of direct sowing of soya beans, the soil layer in 0-30 cm was characterized by values of density and solidity and in the result of it we observed the weak development of the root system. The worsening of air regime led to the decrease of symbiotic nitrogen fixation, it negatively affected on the growth and development of a cultivar. Agrophysical indexes brought nearer to optimal on variants with disposal tip on 20-22 cm and disk-shaped hulling on 8-10 cm. The worsening of investigated agrophysical soil indexes has been happened since the phase of florescence – soya bean formation till the harvesting. But the variant with disposal tip where we observed the high content of agronomically valuable fraction at the coefficient of structural property 2,42 was the closest to optimal ones. The minimization of soil treatment and especially the denial from its implementation significantly made worse the main agrophysical indexes of soil on variants with direct sowing to critical values for soya beans
The article shows the results of years of research, which showed that the intermediate culture - is an important factor in the impact of increasing the fertility of meadow black soils, meadow (rice) soils perform environmental, agronomical and soil protection roles,
as well as they are involved in the biological cycle of nutrients
