Providing plants with phosphorus – one of actual problems of agriculture of Ukraine.
In soils of its stocks will suffice on many tens years, but it is in the earth in a form inaccessible to much plants. And factor of assimilation even the best phosphoric fertilizer – superphosphate very low – 15-20 %.
One of perspective solutions of this problem – application of microbic preparations (fosforobakterina) which are capable to transform almost insoluble compounds of phosphorus to forms which are easily acquired by plants. Action of such preparations is equivalent to influence 30-40kg active ingredient of phosphoric fertilizers.
At institute of agricultural microbiology UAAN (Chernigov) are created and already brought in the List of the pesticides resolved for use in Ukraine such preparations, as albobakterin and polimiksobakterin.
Field researches on the vyshchelochenny chernozem showed that when using on a sugar beet albobakterina and polimiksobakterina, productivity of root crops increased with 47 to 53 t/hectares, and a sugar exit – with 7,8 to 9,2 t/hectares. Introduction of superphosphate decreases to 1,5µ/hectare or to 30 kg ñ.ó./hectare.
For corn the new highly effective microbic preparation agrobakterin is recommended. Researches showed that application of a preparation raises a crop of green material on 4-7Ô/hectare, grains on 5Ô/hectare, and the maintenance of a protein in grain makes 3 %.
Application albobakterina and polimiksobakterina positively influences and growth and sunflower development. The crop of seeds thus increases by 14-24 %, and a maslichnost for 1,5-2,1 %.
Use agrobakterina promotes increase in productivity of grain of a soya with 15 to 18 c/hectares, and introduction agrobakterina in komplekses the rizotorfiny gives a crop gain with 15 to 20 c/hectares. The maintenance of cindery elements, a protein to 2,87 %, fat to 2 % thus increases. Good results were received on crops of a lupine yellow and flax-dolguntsa.
Inokulyatsiya of grain of winter grain crops the polimiksobakteriny promoted increase in productivity at 8-21 %, thus the maintenance of a protein increased to 3 %.
All these preparations not only provide plants with available compounds of phosphorus from soil reserves, but also produce growth factors and group B vitamins.
Preparations resistant to pesticides, viability of bacteria on seeds lasts for several months.
Economic effect of application of microbiological preparations reaches 960 UAH/hectares.
