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

Popis výsledku v původním jazyce

Quality of work of fertiliser spreader is one of the most important factors that affect the nitrous oxide (N2O) 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 PÖTTINGER 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 ofapplication 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 61.38 kg N ha-1, respectively. Nitrous oxide emissions were measured 7, 14, 21 and 28 days after fertiliser application and incorporation into the soil by a photoacoustic field gas monitor INNOVA 1412 with a multipoint sampler INNOVA 1309. Concentration of N2O ranged from 0.4264 ppm to 1.2970 ppm. Maximum values were measured 21 days after fertilisation for each vari
