The nitrogen utilization by spring barley and the balance of vitrogen fertilizer

Popis výsledku v původním jazyce

Micro-plot trails on two soil were performed to study the utilization of nitrogen by the spring barley variety jubilant and the balance of nitrogen after application of 15N in the form ammonium sulfate with 25 %enrichment. For rates (0,30,60 and 90 kg Nper ha) were applied. An uptake by spring barley aboveground biomass of nitrogen at the time of harvest was dependent statitistically significantly on a soil pH level. The balance of fertilizer nitrogen in soil - plant system indicates that 39 - 44 % ofthe rate applied in neutral soil was used by spring barley within 2 years, 27 - 37 % remainded in soil and 23 - 31% of nitrogen fertilizer was not found. In strongly acid soil, the utilization of nitrogen was low: 24* - 28 % was used by plants, 13 - 15 %was left in soil and 59 - 61 % was not found.
