The changes in microbial biomass nitrogen, when different rates and forms of N vere applied in a long-term experiment with maize
Original language description
The effect of different rates and forms of organic and nitrogen fertilizers on the amount of soil microbial biomass nitrogen was investigated in the long-term field experiment with continues maize.The contents of microbial biomass N fluctuated between 5.2 mg Nkg-1 to 22.7 mg Nkg-1. The highest contents of microbial biomass N were estimated in the variant treated with manure (17.2 mg Nkg-1 to 22.7 mg Nkg-1). A positive influence on the contents of the microbial biomass N came from application of slurry.The contents of microbial biomass N was estimated to be 29 % higher than in the control. In treatments with mineral N fertilisers (AS, UAN), there was a tendency towards a lower contents of microbial biomass, compared with the control. With UAN, the average contents of microbial biomass N reached 83 % of that in the control and with amonium sulphate it was 61 %. Addition of straw caused an increase in the content of microbial biomass N by 36 % compared with UAN treatment.
