Very interesting…Did some searching, and math, and 55# of lignosulfonate powder is $191. That should make approx 500 gallons of ready to spray mix. At an application rate of 0.3 gal/sy=1000 square yards or 9,000 sq ft, or a single lane, about 12 ft x 750 ft; or two lane, 18 ft x 500 ft. It recommends reapplying every 3-9 months.
Now, you Do need to wet the surface before applying, so
Wondering how to mix it. I may try this next year. Maybe get one of those large steel encased totes and design dome kind of spray system. I doubt this would work using my field weed sprayer?
