Mineralization Activity in Soils for the Development of the Precision Farming Systems

Abstract

Respiration and ammonification tests were used for the determination of microbiological activity in soils which was complexly investigated within a project aiming in the development of precise farming. The tested sites were chosen according to their nutrient content and yield potential (low - medium - high). Long-term respiration tests showed that there were no significant differences between spring and autumn mineralization activity in vitro and among localities. The amendment of lucerne meal in this test resulted in significantly higher mineralization activity. The increase in potential mineralization activity indicates a good biological activity of the tested soils. Basal and potential (with ammonium and glucose amendment) respiration in short term respiration test was significantly lower in soils from poor sites. The tendency to growing ammonification activity from poor sites to the best ones was determined.
