Summary

In an EU CRAFT project (COOP-CT-2004-508458) running from March 2004 to March 2006, an international consortium of producers of environmentally benign crop inputs, RTD performers and end users, evaluated the production and use of products manu-factured from different raw materials such as seaweeds, pine needles, trees and herbaceous species or physically hydrolysed bovine fur and hair residues. At the field level, the products were applied as solid pellets or liquids, as fertilisers or sprays, respectively. This paper presents as an example results from field trials of organically grown potatoes and tomatoes at the University of Kassel. Assessments were per-formed on yield, plant health and quality aspects. In most of the experiments solid products (pellets) with nitrogen contents between 7 to 12% resulted in comparable growth effects as obtained with hornmeal fertilisers. However, one of the liquid prod-ucts applied as a spray in potatoes increased yield significantly. A combination of the same liquid and a solid product based on plant raw materials reduced plant and fruit late blight in a field trial with open-field tomatoes. It is concluded that especially the combination of well adapted liquid and solid products can have promising effects on crop performance.
