Abstract: 
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 ZnSO4/Na2B4O7. By this, average NO3--N contents of 48.7 ppm were detected in leachates from cattle manure heaps (n = 54).
