The effect of biofertilizers on soil microbial activity and basic morphological characteristics of camellia sp and cupressus sp.

Abstract

This paper examines the effect of Enteroplantin and Slavol on soil microbial activity (count of microorganisms, numbers of azotobacter, oligonitrophiles, soil fungi and actinomycetes) and growth (length of underground and aboveground plant parts) of Camellia sp. and Cupressus macrocarpa gold crest, grown in vegetative pots. Microbial counts were determined by an indirect method of growth on specific selective media. Enteroplantin and Slavol induced an increase in the number of all examined groups of microorganisms, except soil fungi. Enteroplantin was found to be particularly effective in this respect, having a more stimulating effect on the growth of roots and aboveground parts of both plants, in the course of the entire study period (2006-2008). The observed growth of the aboveground parts and roots of both plants, the established values of soil microbial parameters, and potential economic and environmental effects suggest that Enteroplantin and Slavol can be recommended for use in cultivating Camellia sp. and Cupressus macrocarpa gold crest.
