GvX formula (Micah Woods, PACE Turf):
GvX = (ClipVol₁₄d / (20 × GP₁₄d)) × 100
GvX = (ClipVol₁₄d / (20 × GP₁₄d)) × 100
Growth Potential (Gelernter & Stowell):
GP = exp(-0.5 × ((T − 20) / 5.5)²) — cool-season C3 turf
GP = exp(-0.5 × ((T − 20) / 5.5)²) — cool-season C3 turf
100 = growing exactly as expected · >120 = over-growing (excess N or water) · <80 = under-growing (stress / under-fed).
GP = exp(-0.5 * ((T - 20) / 5.5)^2). GvX = (ClipVol_14d / (20 × GP_14d)) × 100. 100 = on the line, >120 over-growing, <80 under-growing.
