Visible color and turf-condition changes were reported within 11–14 days.

After 14 days of KPCB use, the soccer-field turf was reported as greener and healthier than before. Dead and bare grass areas had begun filling in with healthy, vigorous, vibrant green grass. At a nearby park, the grass was reported to have changed from a dull color to vibrant green after 11 days.

The supplied case study reports visible changes in turf color and condition rather than instrument-based turf measurements. The soccer field was described as greener and healthier after 14 days, with dead and bare spots beginning to fill in. This does not establish that all turf had completely regrown within 14 days. The nearby park observation was reported after 11 days and is a separate site. No NDVI, chlorophyll, turf-density, biomass, root-depth, percentage ground-cover, irrigation, fertilizer, pesticide, or quantified control measurements were supplied. The $500 figure represents historical spending on inputs every three to four months; the source does not provide KPCB treatment cost or subsequent input spending, so no dollar savings or return on investment is calculated.

Why this matters for turf managers: This Trujillo case documents visible turf-condition changes over a short observation period. The soccer field was reported as greener and healthier after 14 days, with bare areas beginning to fill in, while grass at a nearby park was reported as vibrant green after 11 days.
