Assessing effects of the waterholding bioproduct Lipomycin M on the amount of effective water in the soil

Abstract

Biological solution using strain Lipomyces starkeyi 7.1, which can produce viscous membranes to improve dry soil is considered to be sustainable for slope land improvement. The results of research on Lipomycin M ability to keep effective water in the soil of Me Linh District, Vinh Phuc Province show that in the soil samples cultivated traditional medicinal trees, the total amounts of effective water in the soil fertilized Lipomycin M (taken out under pressure pF 2.5-4.2) are always higher than that in control soil plot (without Lipomycin M): the amounts of effective water in CT2 account for 24.8%, CT3 - 25.1% in comparison with DC (control plot) - 17.1%. Combination of Lipomycin M with NPK and microbial fertilizers makes the amount of effective water in the soil higher than that in the case of using only Lipomycin M. Similarly, the amounts of effective water in the soil samples cultivated tea and manured the bioproduct Lipomycin M are higher than those for the soil sample DC and proportional to the times of manuring the bioproduct: TN3 - 29%, TN1 - 24.8%, and DC - 22.2%.
