Joint Crop Trial Proposal

SAKALA International × SOIL Haiti — Comparative Growing Media Research Program
Proposed by: Daniel Tillias, SAKALA International & Wesley Bertil, BARSS LLC
Proposed to: SOIL Haiti
Site: SAKALA Compound, Cité Soleil, Port-au-Prince
Duration: 6 months (extendable)
Date: April 2026

1. Executive Summary

SAKALA proposes a joint crop trial with SOIL Haiti comparing the effectiveness of SOIL Konpos Lakay at four concentration ratios across 8 crops, with parallel hydroponic control trials on selected crops. The research will be conducted by SAKALA franchise youth (ages 16+) at the SAKALA compound in Cité Soleil, with remote analytical support from BARSS LLC and academic oversight from UEH FAMV. All data will be shared with SOIL for product validation and marketing. Co-authorship on any resulting publications.

2. Research Design

Track A: Soil-Based Container Trials (SOIL Compost Evaluation)

For each crop, 4 treatments:

3 replicates per treatment = 12 containers per crop.
8 crops × 12 containers = 96 containers total.

Crop Kreyol Name Why Selected Growth Cycle Expected Harvest
Pourpier (Purslane) Koupye / Poupye Edible, nutritious, thrives in poor soil. Crossover with Track B. 30–45 days Month 2
Moringa Benzoliv SAKALA anchor crop. Tree growth measurement. First leaves 60 days Month 3 (leaves)
Peppers (piman zwazo) Piman Franchise product. High value. Crossover with Track B. 90–120 days Month 4–5
Yam Yanm Haitian staple. Tuber, needs soil depth. Long cycle. 6–9 months Month 6+
Aloe Lalwa Medicinal, skincare. Easy tropical grower. Continuous Month 3+
Alfalfa Alfafa Animal feed + microgreen potential. Nitrogen fixer. 30–60 days Month 2
Azolla Azola Aquatic fern. Nitrogen fixer. Animal feed protein (25–30%). Doubles every 3–5 days Month 1 (continuous)
Nèswi Nèswi [Local crop — confirm with Dan. Placeholder pending identification.] TBD TBD

Track B: Hydroponic Control Trials (Selected Crops Only)

For crossover comparison, grow the same crops in hydroponic systems alongside soil containers:

Crop Hydroponic System Nutrient Solution Purpose
Pourpier Kratky (mason jar) Masterblend 4-18-38 Direct comparison: SOIL compost vs hydroponic yield
Peppers Drip system (bucket) Masterblend Direct comparison
Alfalfa Microgreen tray Masterblend Harvest as microgreens (7–14 day cycle)
Azolla DWC float (tray of water) No nutrients needed (fixes own nitrogen) Biomass production rate
Lettuce (bonus crop) Kratky + DWC Masterblend Benchmark crop (most studied hydroponic crop)

5 hydroponic crops × 3 replicates = 15 hydroponic units.

Total experimental units: 96 containers (Track A) + 15 hydroponic units (Track B) = 111 units.

Track C: Nursery Propagation (Concurrent, Separate Data)

Not part of the SOIL proposal directly, but runs on the same site:

3. Measurements & Data Collection

Parameter Frequency Tool Who Collects
Germination date Once (record when seedling emerges) Visual observation Youth (Role #8)
Plant height (cm) Weekly Ruler Youth
Leaf count Weekly Count Youth
Stem diameter Bi-weekly Calipers or ruler Youth
Visual health rating (1–5) Weekly Photo + rating scale chart Youth
Photo documentation Weekly (same angle, same time of day) Smartphone Youth
Soil/water pH Bi-weekly LaMotte kit or pH strips Youth (10-min training)
Hydroponic EC Weekly (Track B only) EC meter (HM Digital COM-80) Youth (10-min training)
Days to first harvest Once per crop Calendar Youth
Harvest weight (grams) At each harvest Kitchen scale (0.1g) Youth
Post-harvest soil pH End of trial LaMotte kit Youth

All data entered via KoboToolbox on smartphone (offline-capable). Form designed by BARSS with dropdown menus, number fields, and photo capture. Data syncs to cloud when internet is available. BARSS monitors data quality remotely.

4. Why 16-Year-Olds Can Do This

Task What It Actually Requires Trainable in...
Mix soil ratios Follow a recipe (3 scoops sand, 1 scoop compost) 5 minutes
Fill containers Shovel + hands Already know how
Plant seeds Put seed in hole at correct depth 5 minutes
Water on schedule Calendar + watering can Already know how
Measure height Read a ruler Already know how
Count leaves Count Already know how
Record on KoboToolbox Tap phone screen, type number 30-minute training
Take standardized photo Phone camera, same angle marker on ground 10 minutes
Weigh harvest Put on scale, read number 5 minutes
Mix hydroponic nutrients Measure grams on scale, pour into water, stir 20-minute training
Test pH Dip meter in water, read number 10 minutes
Spot problems "Does this look different from the others?" + photo Ongoing mentorship
What youth CANNOT and DO NOT need to do:

The youth are trained data collectors running a pre-designed protocol. The scientific rigor comes from the design and analysis, not the collection. This is standard practice in agricultural field research worldwide — trained community members collect data, researchers analyze it.

5. Supervision & Quality Assurance

Level Who Role Frequency
On-site daily SAKALA Youth (Role #8: Nursery/Research) Daily measurements, watering, photos Every day
On-site supervision SAKALA Franchise Manager (Role #10) Ensures protocol followed, resolves issues Daily check-in
On-site scientific Dr. Mac Archer (BARSS, Haiti-based) Verify methodology, troubleshoot, quality audit Bi-weekly site visits
Remote analytical Wesley Bertil (BARSS, Delaware) Monitor KoboToolbox data, flag anomalies, run statistics Real-time via dashboard
Academic oversight UEH FAMV (Prof. Neudy Jean-Baptiste, Vice-Dean Research) Scientific review, student intern placement, co-authorship Monthly review
Partner liaison SOIL Haiti Compost supply, technical input on compost application, shared results Monthly check-in

8. What SOIL Gets

SOIL provides approximately 500 kg of Konpos Lakay (valued at $0–75). In return, SOIL receives:

  1. Publishable data showing Konpos Lakay's effect on 8 crop varieties at 4 concentration ratios — data SOIL can use in marketing materials, grant applications, and partner presentations.
  2. Side-by-side comparison with hydroponic growing (Track B) — demonstrating where soil-based compost growing matches or exceeds high-tech methods, proving the value proposition for low-tech farming contexts.
  3. Connection to SAKALA's 344-franchise network — every franchise that deploys will use compost. At 344 franchises each using 500+ kg/year = 172,000+ kg/year of compost demand. This trial is the data that justifies that supply contract.
  4. Co-authorship on any resulting publications — shared credit in academic journals (target: JARTS, Tropical Agriculture UWI, PLOS ONE).
  5. IDB alignment — both SAKALA and SOIL are IDB partners (HA-L1106). Joint research strengthens both organizations' positions in the IDB ecosystem.
  6. Youth training pipeline — SAKALA franchise youth trained in composting through this trial become the workforce that scales SOIL's compost application across Haiti.

9. What SAKALA Gets

SAKALA invests approximately $521–653 in materials and provides the site, labor, and coordination. In return:

  1. Optimized crop/medium combinations for all 344 future franchises — the trial directly informs what goes in every raised bed.
  2. Hydroponic system validation — Track B data proves which crops are worth growing hydroponically in Haiti conditions, informing the Type 12 Hydroponics Training Center design.
  3. Youth trained in agricultural data collection — the 10 franchise youth who run this trial graduate with real research experience, forming the foundation of the SAKALA certification program.
  4. Academic credibility — co-authored publication with SOIL and UEH validates SAKALA's research capacity for future grant applications.
  5. SOIL partnership formalized — moves from informal relationship to documented research collaboration with shared data and mutual benefit.

This is a $521–728 research program that produces publishable data, validates a commercial compost product, trains 10 franchise youth in agricultural science, and optimizes the growing model for 344 future franchises. The cost is less than a single franchise. The value compounds across every franchise that ever deploys.
