Case Study
Virú, Peru: From passionfruit monoculture to regenerative polyculture.
TANIT partnered with Cooperativa Agraria El Sembrador to transition a conventional passionfruit monoculture into a verified, biodiverse polyculture system using Integrated Trophic Design.

Polyculture system

Baseline SOM
Baseline pollinators
5 visits / 100 flowers / hr
Initial challenge
A fragile monoculture in sandy soil.
Low soil organic matter
Sandy soil with only 0.2% SOM, low water retention, and minimal soil structure — typical of dune ecosystems where conventional practice has further degraded fertility.
Lack of biodiversity and resilience
Passionfruit monoculture provided no functional biodiversity, no pollinator habitat, and no natural pest regulation — leaving the system vulnerable and input-dependent.
High external input dependency
Soil fertility and pest management relied entirely on synthetic inputs, creating a cycle of cost and ecological risk with no pathway toward stability.
TANIT solution
Integrated Trophic Design: a three-species polyculture.
TANIT developed an AI-informed ITD plan with a TANIT-certified agronomist, designing a companion crop system to restore soil function, attract pollinators, and diversify the ecosystem without replacing the primary crop.
Passionfruit
Primary crop
Maintained as the high-value commercial crop and the focus of yield and traceability evidence.
Sunflowers
Pollinator attractor
Planted in dedicated rows to draw bee and native insect diversity across the field — critical for passionfruit yield.
Pigeon Pea
Soil fertility & system resilience
Intercropped between rows to fix nitrogen, prevent erosion, provide wind protection, and reduce pest and disease pressure through diversification.
AI-informed intercropping plan implemented under guidance of a TANIT-certified agronomist, with the partial inclusion of sweet potato as a ground cover layer within the intercropping system.
Verification process
How the T4 baseline was established.
Soil sampling
Full soil profile collected by TANIT-certified technician following standardized field protocol.
Visual biodiversity surveys
Insect and plant count surveys conducted across the farm to establish functional biodiversity baseline.
Farm practice interviews
Structured interviews documenting current input use, management practices, and farmer knowledge.
Laboratory analysis
Samples analyzed by TANIT's partner laboratory in Lima for quantitative soil chemistry data.
T-Tier classification
Results assessed against Restorative Spectrum baselines to determine initial T4 classification.

Expected passionfruit yield
January – August
Expected harvest period
Pollinator activity increased
Observable increase in bee and native insect activity across the farm as sunflowers drew pollinators to the passionfruit crop.
Synthetic inputs eliminated
Within the first implementation cycle, the farmer eliminated synthetic inputs entirely — switching to bio-inputs including humic/fulvic acids and microalgae.
Ground cover exceeded 50%
Ground cover increased from below 30% to above 50%, improving soil moisture retention, erosion resistance, and weed suppression.
T3 progression projected
Based on successful multi-strata polyculture implementation and verified practice commitment, T3 classification is projected by end of the first full harvest year.
Yield and T3 projections are based on current implementation progress and are not guaranteed outcomes.
Regenerative intelligence
TANIT's Regenerative Intelligence Infrastructure.
Ecosystem Design
AI-assisted ecosystem planning structures climate-resilient transitions, crop diversification, and reduced synthetic input dependency.
Field Verification
Technician-supported field data, soil analysis, biodiversity observations, and farmer interviews validate baseline and transition progress.
Intelligence Layer
TANIT turns verified field outcomes into traceability, reporting, and buyer-ready evidence.
Verified field outcomes continuously improve future ecosystem designs.

Irrigation Usage
Noticeable insect diversity improvements, reduced fungal rot, and complete synthetic input elimination were observed in the Peru pilot plot.
Cooperativa Agraria El Sembrador also reported increased yield because the TANIT-managed crop area suffered much less fungal growth after a period of hot weather and heavy rains.
Social impact
Community-led knowledge sharing.
Inspired by early results, Cooperativa Agraria El Sembrador established a local Círculo de Agricultores — a farming circle — to share ITD intercropping methods with neighboring producers. This cooperative-led initiative creates a scalable model for community-wide regenerative transition and directly improves the Capacity Building pillar score on the Restorative Spectrum.
Next steps
Scaling and deepening the program.
Ongoing quantitative monitoring across all six Restorative Spectrum pillars.
Yield and processed-product data collection post-harvest.
Scale through the associated cooperative: 35 members, 60 ha of passionfruit.
Expand ITD coverage from 6,000 m² to 15,000 m², with full 15 ha goal by 2026/2027.
Introduce sweet potato as a dense cover crop to reduce erosion, evaporation, and weed growth.
Connect harvested produce to processing partners for powder and oil production.
