RELATIONSHIPS BETWEEN SOIL PHYSICO-CHEMICAL PROPERTIES AND BACTERIA COUNTS IN OAK FOREST SOIL
Journal Title: Natural Resources and Sustainable Development - Year 2013, Vol 3, Issue 1
Abstract
Variation of the number of Actinomycetes and nitrifying bacteria and of some physical and chemical soil properties associated with environmental changes of the oak forest soil were investigated during the spring and autumn of the year 2013. Soil samples were collected from 2 locations Z1 (zone 1) and Z2 (zone 2), under one site, namely Cefa-Ateas forest, Oradea forest district, located at 30 kilometers from Oradea, Bihor County. The variability of selected soil properties, relationship between physico-chemical and microbiological soil properties and the statistical significance of means differences between zones, seasons and interactions were studied using the statistical method: one-way analysis of variance (ANOVA) and principal component analysis (PCA) The results show that ecological factors such as: relative moisture, soil hydrolytic acidity, sum of exchangeable bases, mobile phosphorus, humus, C:N ratio, are important factors that influence the soil microbial populations of Actinomycetes and nitrifying bacteria in the studied forestry ecosystem. Relationship between soil microorganism’s counts, physical and chemical properties of the soil was significant. Also, the results of revealed significant differences between zones of Actinomycetes, mobile phosphorus content, C:N% ratio and sum of exchangeable bases. Relative moisture, humus and ammonia nitrogen variables are responsible of season groups discrimination, but with different abundance.
