Hay Green is a buffered propionic acid preservative for processing high moisture hay, corn, grain, silage, haylage and feed blends. Hay Green is a solution of propionic acid, ammonium propionate, citric acid, ammonium citrate, surfactants,and colorant. The minimum propionic acid content is %. In addition, Hay Green also contains % citric acid. The total concentration of working ingredients is % - a maximum of only % water. The pH is controlled at to with a specific gravity of - (#/gl). The Citric Acid has significant benefits when baling high moisture hay. Citric acid imparts a sweeter fragrance to the hay and the hay stays green in color. The hay retains a couple of percent more moisture on drying. Citric Acid allows baling at a higher moisture level than normally recommended - a benefit when weather does not allow drying as low as would be preferred.
