To thank Inagro's field trial owners, a barbecue and tour of the site were organized on 25/8. Our field trial fertilizer was also shown during this tour: the participants were clearly interested in this machine. We gave small groups of interested people an explanation of the operation and technical characteristics of this high-tech machine. We also explained the ReNu2Farm project and the design of our field trials. The field trial fertilizer was specifically developed to deal with the complexity of the field tests.
