Микрофлора в рекултивирана обработваема площ от района на „Марица – Изток“.

The microflora has been examined in a reclaimed arable land from area of Maritza – East. Agrochemical and physical analyzes have been made at eight different points of the site and the amount of basic groups of soil microorganisms – ammonifying and cellulolytic microorganisms, mineral nitrogen- utilizing bacteria, actinomycetes and microscopic fungi has been determined. It has been found that in the reclaimed arable area of Maritza – East, microbiological processes of varying intensity take place, depending on the point of sampling, agrochemical and physical parameters of the soil. Ammonifying microorganisms and mineral nitrogen-utilizing bacteria are in greatest quantity at sampling points with low mineral nitrogen content. Actinomycetes and microscopic fungi have better development at points with a lighter mechanical composition. Plant residues in the soil affect cellulose-decomposing microorganisms.Ammonifying microorganisms and mineral nitrogen-utilizing bacteria are in greatest quantity at sampling points with low mineral nitrogen content.
