Are we mining the soil ? (OK-Net Arable Video)

Summary in the original language of the document

Seven organic farms took the opportunity to look at one or more of their fields. They gained insights into their rotations and NDICEA seems to be a useful tool for assessing nitrogen supply/losses throughout a rotation.
The results on the farms indicate that there is a danger of losing nitrogen even in organic rotations. In the video, the researcher summarises the results and one of farmers taking part shares his thoughts. The common conclusions are that spring ley cultivation and strategic use of organic fertilisers are possible strategies for improving nutrient balances in organic farming. 'Flying livestock' and innovative strategies to keep the soil covered (e.g. living mulches, undersowing) may also help.
