Humus dynamics were basically influenced by environmental site conditions, but at a given site differences between farming systems could be ascerted. Mixed farming systems with farmyard manure application as a rule had a more favourable impact on humus dynamics than stockless systems. Whether an advantageous performance of humus dynamics in organic farming as compared to conventional farming will occur or not, is dependent on the respective farm types of both systems that are related to each other. 2008 published public 8531 1 12536 1 rtf de public
