COMPARATIVE DESCRIPTION EFFECTS OF THE SOIL HORIZON AND CROP TYPE ON THE MICROORGANISMS VARIATION IN AGRICULTURAL SOILS FROM CRISURILOR PLAIN
Journal Title: Natural Resources and Sustainable Development - Year 2015, Vol 5, Issue 1
Abstract
Abundance of the microorganisms in the soil in relation to soil horizon and crop type was evaluated. The soil samples were collected from an experimental plot located in Cauaceu, Bihor County, in the spring and autumn of the years 2014-2015. The quantitative variation of three ecophysiological microbial groups was studied: aerobic mesophilic heterotrophic bacteria, fungi and Actinomycetes. The plate count method was used to estimate the total number of the studied microorganisms. The two-way analysis of variance ANOVA was used to determine the significance of mean differences between the microbiological parameters for the soil horizon and crop type factors. The results showed that the crop type factor is the dominant factor with effects on the variation of the bacteria population while the fungi population is influenced by the both horizon and crop type factors that shows high variation amplitude.
