Sodium bisulfate may provide an effective management practice for the reduction of alcohols and ammonia emissions from dairy housing conditions. Application of sodium bisulfate (Parlor Pal) has been demonstrated to be effective in the mitigation of both ammonia and alcohols (methanol and ethanol) emissions from fresh dairy slurry. Ammonia emissions decrease with increasing levels of SBS treatment. Methanol and ethanol emissions also decrease with an increase in the amount of SBS applied.
Product should be applied to dairy drylots with a fertilizer spreader twice per week at a rate of 50 - 75 lb/1000 ft2 for control of ammonia, methanol, and ethanol emissions. However, SBS should not be spread evenly but rather topical around highly frequented cow areas (feed bunk, water troughs). Studies conducted at the University of California at Davis (UCD) showed reduction of ammonia of 61% from fresh manure. Application to enclosed drylots at UCD showed reductions of methanol and ethanol of 15-30%.
Bulk cost of product delivered to the farm is $660.00/ ton. Application at 50 – 75 lb / 1000 ft2 2X / week equates to costs of between $33.00 – $49.50 / 1000 ft2 / week. Treatment of heavy use areas, approximately 30% of the total pen area, reduces total pen cost by 70%. Cost / cow assuming 4 cows / 1000 ft2 of pen area would be $2.48 - $3.71 / week treating only the heavy use areas.
