Abstract:
A high N input originating from intensive application of effluent water may well increase dry-matter production but it also increases the pollution hazard. Frequent application of relatively small quantities of effluent water was suggested as an efficient method of improving N uptake by Chloris gayana swards. It was expected that nitrate pollution would be reduced and N fertilizer could be saved. Irrigation according to 100% class A pan evaporation (c.1000 mm) revealed the superiority of twice-a-week application of effluents on fine soil. This schedule resulted in high yields and high N recovery as well as no response to additional N fertilization. Differences between irrigation frequencies diminished as N input increased, and effluent application was reduced to 80% of class A pan evaporation. Total N input higher than 660 and 380 kg/ha did not increase dry-matter production on fine and sand dune soils, respectively, but did increase N losses.-from Authors
