| After a completed rotation of seven years, soils of the Manure as a Chance (MAC) trial were analysed for the effect of organic amendments on soil physical, chemical and biological properties. Yields suggest significant differences due to different organic amendments after seven years. In treatments receiving farm yard manure and bio waste compost yields increased over time. Soil properties indicate changes in soil carbon, nitrogen mineralization en plant feeding nematodes due to different organic amendments. No significant changes in microbial and fungal biomass were found. |

| Understanding organic management practices is a key in developing sustainable organic farming systems. We report the results of four different organic fertilization strategies in a field trial on yields, soil quality and economic performance. We found highest yields and economic performance in two direct plant feeding strategies. One of these strategies, a newly developed strategy based on biowaste compost (GFT) and an additional fertilizer performed well in terms of yields but looks also very promising in terms of soil quality and biodiversity. The economic perspective of this strategy renders it promising in regions with little animal manures. |

| After 8 years, the MAC field trial in Lelystad, the Netherlands, shows the effects of different fertiliser strategies, ranging from animal manure to plant compost to mineral fertiliser. The impact on yield, soil quality, soil health, environment and climate change is discussed. The trial is unique in monitoring th eeffect of so many types of fertilisers over so many years. |
