Numbers of phosphate solubilizing microorganisms and phosphatases activities in the rhizosphere soil of organically and conventionally grown winter wheat
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 2
Abstract
In the years 2014-2016 four commercial winter wheat cultivars, released during 2008-2011, were grown in a field experiment at RZD Osiny according to organic and conventional farming systems. Each year in the first or second decade of May samples of rhizosphere soil were analyzed for numbers of colony forming units (CFU) of phosphate solubilizing microorganisms (PSM) and for acid and alkaline phosphatase activities. The synthesis of three-year results has shown that PSM numbers and activity of acid phosphatase in the rhizosphere soil of the tested cultivars were not significantly influenced by the farming systems used, nor by the cultivars. On the other hand, in all years the activity of alkaline phosphatase was significantly higher in the rhizosphere soil of all winter wheat cultivars grown according to the organic farming system than in soil under these cultivars grown in the conventional system.
