About Zylem
Over 30 years of pioneering biological soil health solutions for South African farmers, because sustainability and profitability start in the soil.
A soil-first company, since 1995
Zylem was founded in 1995 by Justin Platt, a plant pathologist with a deep passion for sustainable agriculture. What began as a mission to find biological alternatives to synthetic farming inputs has grown into one of South Africa’s most trusted names in soil health.
Three decades later, the science has caught up with the conviction: healthy soil grows healthier plants, and healthier plants feed healthier people. We bridge the gap between soil science and commercial farming, backing every recommendation with field trials and real results from South African farms.

To improve the biological health of soil through the supply of quality biological products, enabling South African farmers to grow healthier, more profitable crops sustainably.
The values that guide how we farm with you
Soil first
Healthy soil is the foundation of everything. By nurturing the soil ecosystem, everything above ground thrives naturally.
Biology over chemistry
We prioritise biological solutions that work with natural systems, rather than against them. Better for the farm, the farmer and the planet.
Relationships matter
We build lasting relationships with farmers, distributors and partners, providing ongoing support rather than just selling products.
The people behind Zylem
A dedicated group of agronomists, scientists and business professionals united by a passion for sustainable agriculture in Southern Africa.
