University of Florida Peanut Trial: Advanced-Cal vs Gypsum
Three gallons of Advanced-Cal beat 1,250 pounds of gypsum in the same field: 6,300 lb/ac against 5,676, and 866 lb over the untreated check, for about $39 an acre.

Statistics
The breakdown
What happened, measurement by measurement.
Every chart below is transcribed from the report you can open above. Green means the AgriTec program won the measure outright; grey means it came in statistically even, which on a quality measure is the result you want — the yield came without a give-back.
Grade · total sound mature kernels
Every Advanced-Cal rate graded at or above the untreated check.
Advanced-Cal 3 gal/ac vs gypsum
Beat the gypsum standard by 624 lb/ac on a fraction of the material.
Everything else that was measured
Including the measurements that did not move. A trial that only reports what improved isn't a trial.

What the report says
- Advanced-Cal at 3 gal/ac was the top treatment at 6,300 lb/ac, 866 lb over the untreated check, a 16% gain.
- That 3 gal/ac pass also beat a full 1,250 lb/ac gypsum program by 624 lb/ac: three gallons against well over half a ton of material.
- The 3 gal/ac treatment finished first or second out of five in all four replication blocks, so the average is not resting on one lucky plot.
- Grade held: TSMK ran 73.7% on both the 3 gal/ac and gypsum treatments against 72.3% untreated.
- One pass at early pegging, sprayed in 10 gal/ac of water. All plots received the identical UF herbicide, fungicide and insecticide program.
Trial notes & scope
- One year, one site, small replicated plots, per the report's own fine print. It notes that yield differences of this size can sit within normal field-to-field variability.
- The report carries no p-value, LSD or CV, so the yield figures here are measured plot means rather than separated treatment means.
- Rate response is not a straight line: 4 gal/ac returned +40 lb/ac while 3 and 5 gal/ac both gained. More calcium is not automatically more yield, which is the argument for sizing the rate off a soil test rather than a blanket number.
- The untreated grade figure is a 3-plot average because one check plot's grading sample was not available.
- The ROI figures assume 275-gal tote pricing at $13.09/gal and a $500/ton farmer-stock price. Your delivered cost and contract price will differ.
