Abstract:
This paper presents the
results of an experiment conducted on two
temporary meadows, situated in the
Southern area of the Moldavian Plain, set up
by sowing a mixture made up of Onobrychis
viciifolia Scop. (sainfoin) and Bromus
inermis Leiss. (smooth bromegrass) at
different rates. We have analysed the soil
microbiological activity of the two
temporary meadows, as influenced by the
fertilization with an unconventional product
(Vinasse Rompak - 3% N, 0.5% P, 7% K
and pH 7-8) and with different rates of
organic and chemical fertilizers. The
objective of this investigation was to isolate
and quantify the microbial population found
in soil (Gram-positive bacteria, Gramnegative
bacteria, micromycetes and
nitrogen-fixing bacteria), thus establishing
their percent, main fungus genera, which
activate in soil and their activity level for
each variant. The results have shown the
influence of the fertilization on the total
number of microorganisms, on the
relationships between the main groups
(bacteria and fungi) and on the various
micromycete species, determined in each
variant of our experiment.
