| Conclusions |
Multicote Agri is much more efficient and effective than current liquid fertilizer applied, resulted in 6 mT / ha, with a considerable reduction of 20% of the N fertilizer applied
A 40% reduction yielded 3 mT / ha. Both Multicote Agri treatments (80%, 60% of the grower’s practice) are more economically profitable |
