Feeding cows a mixture of high-temperature wood biochar and molasses has had the potential to reduce costs for the farmer, to improve soil properties, and to improve pasture health. Dung beetles moved the dung and biochar through the soil horizon to increase stable C and to enhance soil fertility. The C lattice of biochar appeared to undergo minimal changes as it passed through the gut of the animal. The biochardung composite had a high N concentration and there was an increase in C–O and C–OOH functional groups. Once in the soil the biochar started to age through interaction with soil organic and mineral matter. Available P and N concentrations of the soil around the biochar increased due to a series of complex reactions. These changes could occur over a range of depths as biochar was taken through the soil profile quickly by dung beetles.
