After, almost 15 years in the fertilizer sector and in sales, I thought there was nothing more for me to learn.
Luckily for me, I was wrong. I was impressed by Guy’s ability to share his knowledge to the novice attendee but at the same time, to challenge the experienced one.
The “Fertilization & Irrigation” course is a must-do for anyone in the fertilizing industry. Highly recommended!

I’m glad to inform you that I have finished the course. The depth of explanation with the Cropaia fertilization and irrigation unmatched. I’m so glad I took this course with you.
