Mr Caleb Odondi Omollo at his syntropic Agriculture farm in Kosodo Village, Migori County
In the rolling rural landscape of Kosodo Village, Migori County, a quiet but deliberate farming revolution is taking shape—one rooted not in chemicals or heavy machinery, but in soil biology, plant diversity, and an intimate understanding of how nature regenerates itself.
At the center of this transformation is 68-year-old soil permaculture practitioner Caleb Odondi Omollo, whose farm has become a living laboratory for syntropic agroforestry and regenerative agriculture.
In a region increasingly battered by prolonged droughts, erratic rainfall, and declining soil fertility, Omollo’s work offers a compelling alternative for smallholder farmers struggling to keep their land productive.
For more than six years, Omollo has dedicated his time to experimenting with and teaching regenerative farming methods that rebuild soils rather than exhaust them.
His farm now doubles as a training hub, attracting farmers eager to learn how to restore degraded land while securing reliable food production under changing climatic conditions.
“Syntropic agriculture is about understanding how plants support each other,” Omollo explains during a guided walk through his fields. “When we design farms like natural ecosystems, productivity increases and the soil heals itself.”
Farming by Natural Succession
Syntropic agroforestry mimics the way forests regenerate after disturbance.
Instead of monocropping, Omollo introduces crops in carefully planned stages, allowing each plant to prepare the environment for the next.
Cassava is planted first as a pioneer crop. Its fast growth helps break compacted soil layers and provides temporary shade for slower-growing crops such as coffee during their early, vulnerable stages.
Amaranthus follows, quickly covering exposed soil and protecting delicate microorganisms from excessive heat. Sunflowers then take over, adding biomass and deep-rooted soil conditioning, before bananas are introduced to create longer-term shade and a humid microclimate.
Each crop has a function beyond food production—whether it is soil aeration, moisture conservation, carbon storage, or temperature regulation.
“What we are doing here is designing abundance,” Omollo says. “Every plant has a role.”
Soil as a Living System
At the heart of Omollo’s approach is soil regeneration. Central to this is bio-complete compost, a nutrient-rich organic fertilizer that farmers learn to prepare in as little as 14 days through hands-on workshops.
Training sessions begin with material selection—fresh plant matter, animal manure, crop residues, and other locally available inputs.
Farmers are taught to balance nitrogen-rich “green” materials with carbon-rich “brown” materials, manage moisture levels, ensure proper aeration, and monitor temperature changes throughout the composting process.
“We don’t just pile materials together,” Omollo explains. “Farmers learn what is happening at the microbial level—how bacteria, fungi, protozoa, and beneficial nematodes work together to create fertile soil.”
Once ready, the compost is applied directly to crop rows, restoring nutrients and stimulating biological activity.
“In syntropic agroforestry systems, cover crops are planted densely to suppress weeds naturally while improving soil health,” Omollo explains. “The photos above show black nightshade and other indigenous African traditional vegetables which we intentionally grow closely together to maximize ground cover and productivity. After applying bio-complete compost rich in essential soil nutrients, we mulch the empty rows to conserve moisture, enhance soil structure, and create optimal conditions for healthy vegetable growth.”
The result is a vibrant system where soil remains moist even during dry spells, weeds are naturally suppressed, and crops thrive without reliance on synthetic fertilizers or herbicides.
Learning From the Land
Logs strategically placed within crop rows form another critical component of the system. Far from being waste material, they act as underground water reservoirs, absorbing rainwater and releasing it slowly over time. As they decompose, they provide a steady source of carbon, feeding soil microbes and improving long-term fertility.
Meanwhile, leaves and stems from fast-growing plants decompose quickly, adding organic matter and further enhancing soil structure.
“These systems are resilient because they store water, carbon, and nutrients in the soil,” Omollo notes. “That’s what farmers need now more than ever.”
A Scalable Solution for Smallholder Farmers
For many trainees, the appeal of syntropic agriculture lies in its accessibility. The methods rely largely on locally available resources, making them affordable for smallholder farmers facing rising input costs and shrinking profit margins.
Participants who have undergone training report improved yields, healthier crops, and reduced vulnerability to drought. More importantly, they gain practical knowledge they can adapt to their own land.
As climate change continues to reshape Kenya’s agricultural landscape, Omollo believes regenerative systems like syntropic agroforestry offer a viable path forward.
“We cannot fight nature and win,” he says. “But when we work with it, food security becomes possible again.”
In Migori County, rows of thriving vegetables, layered crops, and living soils tell a powerful story—one where regeneration replaces degradation, and farming becomes a tool not just for survival, but for long-term resilience and renewal.
