Effects of irrigation water quality on the recovery of 15N-fertilizer by Sorghum in field study
Abstract15N-labeled fertilizer was applied to Sorghum at different rates (0, 100 kg N.ha-1) to 1m² microplots and with two kind of water (wel water “WW” and treated waste water “TWW”) to Sorghum grown in field during 1997 and 1999.Increases in DM production, N uptake and 15NRF were observed with TWW.About 17% and 36% of the 15N-fertilizer were recovered in the crop with TWW in 1997 and 1999, respectively. Residual effect was higher in TWW(3% vs 5%). Water irrigation quality had no effect on the 15N-labeled fertilizer remaining in the 0-60 cm layer at final harvest. For both water qualities, the major fraction of the residual 15N-fertilizer (about 60%) was recorded in the surface layer. Losses of 15N-labaled fertilizer was unaffected by water irrigation quality being approximately 35% of the applied 15N-fertilizer. TWW irrigation can efficiently substitute WW for irrigation of Sorghum and,simultaneously save nitrogen fertilizer.
