1. Biological Evaluation of NoroTec™ Products NoroTec AB has made extensive biological evaluation of the NoroTec™ Products in own and external research laboratories and in field trials in different countries in agricultural crops. The presentation covers some examples of this evaluation. Specific results with our other products can be obtained on request.

2. Manganese field trials in barley: NoroTec AB and the National Agriculture Advisory Service in Sweden initiated a field trial serie 2004 with manganese treatment in barley and the trial serie ended in 2006. Three trials were carried out each year In four trials out of nine severe mangenese deficiency occured. In each trial with severe manganese deficiency NoroTec™ Manganese shows the highest yield and gives significant higher yield than Mantrac Optiflo. Manganese 235 doesn’t give significant higher yield in comparison to Mantrac Optiflo.

3. Conclusion: NoroTec™ Manganese, formulated according to the NoroTec patents, using organic acids as complex binding / chelating agents has a superior effect compared to, manganese nitrate, manganese carbonate, manganese 80 gram/l formulated with EDTA as a chelate and manganese sulphate under very severe manganese deficiency.
