The effect of ammonium carbonate fertilizers on the biological activity of soil

Abstract

The influence of Ammonium Carbonate Compounds (ACC) and their combination with biologically active substances (VIDAKSes) on microorganism development in rhisospheric soil of agricultural plants as well as enzyme and aminoacid accumulation were studied ander the field and vegetative house. The results of this research were compared with ammonium nitrate application. It was found out that the use of ACC and VIDAKSes induces the development of asporogenic organotrophic microorganisms and nitrogen-fixing bacteria in the root system of the plants contributing to a decreased nitrification activity. The new agrochemicals increase the soil enzyme activity as well as the aminoacid content in most cases.
