A stationary experiment at Agrochemistry chair of Kuban' state agrarian university has revealed certain changes in humus contents and physical and chemical properties of black leached soil after two stages of field crop rotation as a result of long-term application of mineral fertilizers
In the technology of cultivation of sugar beet the significant role is allocated for system of fertilizer. The research problem included studying of influence of various norms and combinations of mineral fertilizers on productivity and quality of this culture. In 2012-14 the stationary field experiment with sugar beet of a grade of "Nero" on an experienced field of department of agrochemistry in educational economy "Kuban" was put and made. Studying of the nutritious mode of the soil is one of the most important questions of determination of effectiveness of fertilizers. Researches showed that the application of double doses of nitrogenous, phosphoric and potash fertilizers, and also the complete fertilizer in double and threefold dose on the chernozem lixivious, has essential positive impact on the maintenance of like elements of a mineral delivery, providing the favorable food mode during body height and cultural development. Fertilizers promoted more intensive intake of nitrogen, phosphorus and potassium in plants of sugar beet. The maximal maintenance of these elements is observed in a phase of clamping of rows. In experience the good harvest of sugar beet was received. Average productivity made about 450 c he (the increase makes ot13,6% to 77,4%). The maximal productivity of root crops is received at importation of N80P80K80 and N120P120K120 also made 620,3 and 633,3 c/he. Our researches showed that sugar content of root crops by options of experience fluctuated from 14,0 to 18,7%. The best results are received in options with importation of N80P80K80 - in these options sugar content made 18,7%.Thus, optimum conditions for sugar beet are created at importation of the complete mineral fertilizer at the rate of N80P80K80
For the purpose of preservation of soil fertility at
relatively low economic expenses, we have conducted
researches on optimization of doses and combinations
of mineral fertilizers by cultivation of field corn hybrid
called "Krasnodar 382" in a stationary field experiment
of the Department of agrochemistry in the training farm
"Kuban", in the conditions of the leached chernozem of
Central zone of the Krasnodar region. The main impact
on receiving high-quality corn gives the content of plant
nutrients in soil. Our researches showed that the
application of the complete fertilizer in various doses
has had influence on the content of essential plant
nutrients in the soil. The maximal values of the content
of mineral nitrogen, available phosphorus and
exchangeable potassium during all phases of vegetation
have been got in options with double N60P60K40 and
triple N90P90K60 dose of the complete fertilizer.
Sufficient supplying the soil with plant nutrients by
fertilizing has entailed the enhance of corn yield. Great
crop of corn has been reaped during the experiment.
After three years of researches, the productivity has
reached averaged 58,7 cwt/hectare. The greatest
productivity has been received in the option with
application of triple and double dose of the complete
fertilizer and amounted 68,5 and 68,0 cwt/hectare, what
is 47% and 45,9% more, compared to the option
without any application of fertilizers. The main
substance, which defines nutritional value of corn, is
proteins. Application of fertilizers under the conditions
of our experiment has promoted enhancing the protein
content in corn. The application of mineral fertilizers
has promoted increase of the content of crude protein in
corn. Maximal it was in option with application of the
complete mineral fertilizer in the double dose of
N60P60K40 – 9.6%, when reaped protein has amounted 6,5 cwt/hectare. Therefore, it is possible to conclude
that it is most expedient to fertilize field corn with the
dose of N60P60K40 and N90P90K60
