The SANBIO ferti-activators can control biotic and abiotic stress and have positive impact to vegetative and resistive processes.
The aim of this study is to evaluate the effects of simultaneous use of SANBIO ferti-activators EPSOMIT and PLANTA on productivity and quality of citrus variety ´Maltese´.
This project is being carried out within the collaboration between the SOTAM, Groupe SOROUBAT, Tunisia and SANBOS GmbH, Germany.
