🌿 SF37 — GOSSYM Cotton
Production Science

The only ACSL storefront with fiber quality simulation. GOSSYM integrates the Farquhar–Ball–Berry biochemical photosynthesis model with 2DSOIL soil dynamics to simulate lint yield, boll development, and four USDA-AMS fiber quality indices — the metrics that determine every US cotton bale's market value.

🌿 GOSSYM Lint Yield & Fiber Quality

Simulate cotton lint yield and fiber quality indices using GOSSYM's integrated Farquhar–Ball–Berry biochemical model with 2DSOIL. Outputs the four USDA-AMS quality grades — strength, length, micronaire, and uniformity — that determine market premiums and discounts on every US cotton bale.

Optimal boll fill: 77–86°F. Above 95°F = heat stress on bolls.
Elevated CO₂ increases photosynthesis 46–99% (GOSSYM SPAR data)
Typical US cotton: 60–120 lbs N/acre
Heat stress reduces boll weight and fiber length

☁ Boll Development & CO₂ × Temperature

Evaluate CO₂ and temperature interactive effects on cotton boll development stages — squaring, flowering, boll set, and boll opening. GOSSYM's SPAR chamber validation confirms photosynthesis increases 46.5–99.1% at elevated CO₂, but boll developmental timing is temperature-driven and unaffected by CO₂ level.

+2°F mid-century, +4°F end-century typical projections
US avg: 800–1000 lbs/acre. Irrigated: 1000–1500 lbs/acre.

📅 Planting Date & Fiber Quality Optimization

Identify the optimal planting date to maximize both lint yield and fiber quality using GOSSYM's fiber quality module. USDA-ARS research shows planting date is the most controllable factor affecting fiber quality — earlier planting avoids heat during boll fill, improving fiber length and strength.

Fiber length and strength decline above 86°F during boll fill

🌿 About SF37 — GOSSYM Cotton Production Science

SF37 is the final storefront in the AgrStak ACSL sector — and the only one in agricultural software to feature integrated fiber quality simulation. GOSSYM integrates the Farquhar–Ball–Berry biochemical photosynthesis model with 2DSOIL two-dimensional soil dynamics to simulate lint yield, boll development, and the four USDA-AMS fiber quality indices (strength, length, micronaire, uniformity) that determine every US cotton bale's market value.
