Abstract
Fertilization, as agro-technical step, is irreplaceable in the process of
achieving high yields. However, in the aim of sustainable agriculture and rural
settlements, it is necessary to establish which systems of fertilization in the
function of protecting biodiversity could be implemented in maize production. That
is why an experiment was established with different systems and ways of
fertilization and during this test hybrid ZP 704 was grown. There was implemented
dressing with mineral nitrogen with two doses (125 and 270 kg N/ha), to ploughed
maize (in amount of 8 000 kg/ha) as an organic matter and mix of mineral nitrogen
(both of dose) and ploughed maize.
Also, in the part of the test in which inoculation seeds before sewing was
implements, as liquid inoculums there are composite of effective race next class:
Azotobacter chroococcum, Azospirillum lipoferum, Klebsiella planticola,
Beijerinckia Derx. They diagnosed that search parameters (amount of organic
substance, the level transformation of organic substance in the organic substance of
the soil, index of total nitrogen and yield seed of maize, were increase quite in the
different combination ploughed maize and mineral nitrogen).
In process of inoculation of seeds, searched elements of the essential mineral
elements of soil (total amount of micro-organisms, bacterium scale from period
cycle nitrogenous) in minimum and middle dose application mineral nitrogenous
had maximum values.
It is concluded that for protection of biodiversity and economical organic
food production, application mineral dressing could be correct with plough organic
substance or with implement diazotrof-a, and in that occasion the amount of
mineral nitrogen could be reduce for 40 kg/ha.
