| Abstract: | Nitrate determination in leachates from farmyard manure by UV absorption A simple, sufficiently sensitive (< 1 ppm NO3?-N) method for nitrate determination in leachates from farmyard manure is described, suitable for routine analysis. The well known determination by UV absorption is preceded by a precipitation of organic matter with ZnSO4BO7. By this, average NO3?-N contents of 48.7 ppm were detected in leachates from cattle manure heaps (n = 54). |
