Gypsum Poultry Litter Amendment

Poultry Litter Amendment













Promoting Improved Poultry Litter Conditions

Amending poultry litter with gypsum results in better litter conditions.

“Ammonia concentration, litter moisture and pH were significantly lower in the gypsum treatment than the shavings treatment at both 21 and 40 day of age. No differences in broiler performance, livability or paw score were observed” University of Georgia, Athens, GA

Why Add Gypsum to Your Poultry Litter?

  • Reduces moisture in litter
  • Binds ammonia from ammonia to ammonium  preventing release into the air
  • Improves composting by reducing spent litter clumping and allowing air to penetrate
  • Improves fertilizer value by increasing calcium and sulfate levels of spent litter
  • Reduces dissolved phosphorus run-off
  • Maintains litter pH levels near 7

Improve Litter Quality

Comparing a gypsum treated barn to an untreated barn you will readily observe differences in the litter characteristics. Percent moisture and pH of the shavings / gypsum treatment will be significantly lower than that of the untreated comparison. This reduction in moisture is due to the unequaled ability of USA Gypsum material to absorb moisture, compared to the untreated sawdust / shavings mixtures. The amount of litter crusting is also visibly less.

Reduce Phosphorous Runoff

Research shows a single application of FGD gypsum on test sites can reduce concentrations of soluble reactive phosphorus (SRP), the most troublesome form in area waterways, by a significant amount. Gypsum-treated plots showed an average 55% reduction of soluble reactive phosphorus in runoff water compared to untreated plots.
