Variability of samples from 10 sites (above) and variability of subsamples from 2 sites (below). Above: Single values (10 different manure samples per parameter; dots) as well as arithmetic means (open squares) for cattle manure sampled in winter 2010/2011, cattle manure sampled in summer 2011, and pig manure sampled in the period November 2011 to September 2012. Please notice the y-axes for NH4-N and total N are (value * 10E002). Below: Single values (10 replicates per site and parameter; dots) as well as arithmetic means (open squares). Please notice the y-axes for NH4-N and total-N are (value * 10E002)
