Building resilience from the ground up — literally and ecologically.
Agroforestry Design / Diseño Agroforestal
Agave rows are planted in contour-based layouts at approximately 2-meter spacing, with 4-meter corridors between rows. These corridors are not empty — they are planted with native trees, shrubs, and heirloom corn, creating a multi-layered system that mimics natural ecosystem structure.
Native species integrated into the system include:
- Tepehuaje (Lysiloma acapulcense) — nitrogen-fixing, canopy structure, soil stability
- Tepame (Vachellia pennatula) — nitrogen-fixing, pollinator support, erosion control
- Palo cuate (Eysenhardtia polystachya) — medicinal, nitrogen-fixing, habitat
- Ozote (Ipomoea arborescens) — rapid post-fire regeneration, ecosystem anchor
- Tepemezquite (Lysiloma divaricatum) — shade structure, organic matter, biodiversity
Many of these species have emerged naturally on the land, confirming the site's native seed bank and regenerative potential.
Soil Regeneration / Regeneración del Suelo
The below-ground ecosystem is as important as what grows above it. Sereno de Cerro treats soil biology as a core lever of resilience.
Fermentation-based microbial inoculant — A mix of mountain soil, molasses, raw milk, and corn flour is applied near agave root zones to stimulate microbial activity and enrich the rhizosphere. This is an active field experiment, not theory.
Biochar — Used for carbon sequestration, soil structure improvement, and post-fire recovery. Integrates the fire event into the restoration strategy.
Compost and organic matter — Corn stalks are cut and placed along agave rows as mulch, returning organic material to the soil and reducing erosion.
The goal is a living soil food web: mycorrhizal fungi, beneficial bacteria, and microbial diversity that supports healthier agave, better water retention, and long-term carbon storage.
Biodiversity & Pollinators / Biodiversidad y Polinizadores
Biodiversity at Sereno de Cerro is functional infrastructure, not decoration.
Landscape-wide pollinator habitat — Of our 5 hectares, roughly 2 hectares remain fully wild — intact tropical dry forest teeming with native grasses, trees, and shrubs that flower seasonally. This is not a designed corridor; it is a habitat block. The remaining production zones have native trees and shrubs growing among the agave rows — tepames, tepehuajes, huizaches, copales, pitayos, nopales — all of which flower and feed pollinators. The result is continuous pollinator habitat across the entire ranch, not a narrow strip.
Why this matters for agave — Agave reproduces sexually through flowers pollinated primarily by lesser long-nosed bats at night and bees and birds during the day. The industry almost exclusively cuts the flower stalk (quiote) to keep sugar in the piña, eliminating sexual reproduction and creating genetic monoculture. When any agave on our ranch flowers — across all 3,000+ plants — the pollinators are already present because the landscape supports them year-round.
Research collaboration — A biologist-led research team is incorporating the farm into a pollinator study, monitoring which species are active and how they move across the property. This is integrated into the project’s grant strategy and long-term identity.
Natural pest control — Beneficial insects are being studied for their role in preventing harmful pests like picudos in agave plantations. Ecological complexity reduces vulnerability to the outbreaks that devastate monocultures.
Data & Measurement / Datos y Medición
Sereno de Cerro is committed to evidence over narrative. Claims will be backed by real measurements, not greenwashed language.
Current and planned data collection includes:
- Soil health metrics — organic matter, moisture retention, microbial biodiversity (BeCrop or alternative methods)
- Biodiversity indices — species counts, pollinator activity, insect diversity
- Erosion and land regeneration indicators
- Carbon proxy metrics — tracking sequestration potential through soil and biomass
- Cost/benefit analysis — profitability implications for producers considering regenerative transitions
This is ongoing work. The measurements will tell the story as the system matures — not before.
Corn & Companion Systems / Maíz y Sistemas Complementarios
Heirloom criollo corn is not a side crop — it is part of the ecological design and value chain.
Corn is sown between agave rows, contributing organic matter, providing ground cover during the rainy season, and eventually yielding grain for sale or processing. The kernels include a distinctive pearl purple and cream variety, reflecting the region's native agricultural heritage.
Corn stalks are cut post-harvest and placed along agave rows as mulch — closing the nutrient loop and protecting soil from erosion during the dry season.
