How I got +22% more wheat in Tunisia

Béjà, Tunisia (June 15, 2017) – The production of wheat seed in Tunisia suffers from major problems in terms of yield, quality and production costs. The aim of this study is to evaluate the effects of ferti-activator Sanbio EPSOMIT on productivity and production costs on wheat variety ´Mâali´.

This project is being carried out as part of the cooperation between Farm Khalil Ben Attia – Tunisia, SGDAI General Society for Agricultural and Industrial Development – Tunisia and SANBOS GmbH – Germany.

4. Conclusion

“I am very convinced of the performance and economic profitability of the fertilizer Sanbio EPSOMIT from SANBOS GmbH. With only 1 kg per hectare, production was increased by up to 22% despite the lack of water up to 35% and the great temperature drop in winter and the very high temperature in summer during the 2016-2017. Despite that we have not used fungicidal pesticides, after the use of the fertilizer Sanbio EPSOMIT we have not noticed problems of fungal diseases like septerose, rust and stress problems. The use of Sanbio EPSOMIT fertilizer has reduced production costs and improved productivity. I recommend the use of the fertilizer Sanbio EPSOMIT in the wheat cultivation.” Ahmed Ben Aissa, 2017
