"Healthy Soil, Thriving Crops: Natural Solutions for Fertility & Pest Control"
June 12th, 2025 – Level 1
June 13th, 2025 – Level 2
Educator: Axel Torrejon (Rayen Soluciones)
Terranima invites you to a hands-on workshop designed for farmers, agri-professionals and garden lovers who want to improve their soil health, cut costs on fertilizers and chemicals, and boost resilience to drought and heat—without sacrificing yield or spending endless hours on complex preparations.
Led by an expert in Regenerative Agriculture, this workshop will uncover how soil microbiology works, how to boost plant nutrition naturally, and how to control pests and diseases without expensive chemicals.
Participants will learn practical, low-cost techniques like:
✅ Producing biofertilizers and humic acids
✅ Multiplying beneficial microorganisms directly on your farm
✅ Improving soil structure to retain water and prevent erosion
✅ Preparing Potassium polysulfide and other key bio-preparations
This two-day workshop is packed with valuable insights so we recommend to attend both days, but if you can’t attend both days, you’re welcome to join for just one.
Dates:
June 12th, 2025 - Level 1
June 13th, 2025 - Level 2
(We strongly recommend to attend both days)
9 am until 7 pm each day / Check-in opens at 8.30 am
Lunch and drinks included for both days

The workshop will take place at Terranima in Badolato, CZ (Italy).
Coming from Badolato Marina, take the exit toward Serra San Bruno, Madonna della Sanità, and the cemetery, which is quite close to Badolato Borgo (you’ll see it on the left). At the first left-hand curve (about 100 meters from the junction), there is a dirt road that leads to Terranima (orange line).
We don’t have enough parking space for all vehicles at Terranima, so we kindly ask you to leave your car along the roadside after the curve (the blue area on the map) and walk 5 minutes to reach the Terranima site.
Thank you.
The admission is free but there are limited seats. Registration is required.
Axel runs a consultancy agency in Spain focused on organic agriculture. He provides support to farmers and companies and he offers training and educational activities for a long time. He works for Rayen Soluciones with clients across Spain, Chile, and Argelia.
He’s an agronomist, with experience with different crops. He has experience in the production of organic fertilizers, organic pesticides, organic fungicides, soil restoration, humic acids, soil analysis interpretation, among others. He has also
experience in monitoring, in particular with chromatography. He will lead the workshop with the help of a translator. He likes to explain some theory but he always includes hands-on.
