Data from a long-term field experiment comparing digested and undigested cow slurry

Data from a long-term field experiment in Norway, comparing digested and undigested slurry from organically managed dairy cows since 2011. The dataset includes chemical analyses of digested and non-digested slurry, soil characteristics at plot level of pH, extractable nutrients, loss on ignition; crop yields and botanical composition. These data supplement the findings presented and discussed in the research article Anaerobic digestion of animal manure – long-term effects on crop yields and soil characteristics.
