Pasture must be in a 'growing state' for ProGibb to give the most beneficial response. Typically this is on the shoulders of the season. Warmer regions may be able to use ProGibb successfully in winter whereas in colder regions the spring / early summer and later summer / autumn will be ideal.
Grazing the pasture before ProGibb is applied is critical. For dairy pastures ProGibb must be applied anytime during the first 0-5 days after the cows leave the paddock. For sheep pastures with lower residuals ideally apply ProGibb within 3-5 days of grazing.
Growing additional dry matter means the pasture requires additional nutrients and moisture to support that extra growth. ProGibb is not a substitute for nitrogen and should not be applied to nitrogen deficient pasture. In fact, applying both nitrogen and ProGibb to pasture results in dry matter increases that are both independent and additive.
