Impact of the quality of work of fertiliser spreader on nitrous oxide emissions released from soil to the atmosphere.

Quality of work of fertiliser spreader is one of the most important factors that affect the nitrous oxide (N 2O) flux from soil to the atmosphere. Calk ammonium nitrate (CAN) with 27% nitrogen content was spread by a fertiliser spreader VICON RS-L connected with a tractor ZETOR 16145 and incorporated into the soil by a power harrow POTTINGER LION 301 six hours after its spreading. Application rate of fertiliser was set for 200 kg ha -1 . There were selected five monitoring points based on the deviations of application rate for values 172.14, 188.01, 200.68, 213.08 and 227.34 kg ha -1 , which means 46.48, 50.76, 54.18, 57.53 and
