Kemira Klasp™ Litter Amendment Kemira Klasp™
(Fe2 (SO

3•9H
2O) Litter Amendment is a dry, granulated form
of ferric sulfate that contains approximately 20% iron as Fe+3. It is nontoxic,
nonhazardous and classified as a GRAS (Generally Regarded as Safe) substance
to be used by the poultry industry in pursuit of best management practices. Klasp
Litter Amendment effectively reduces ammonia, sequesters phosphorous and
nitrogen and efficiently lowers litter pH while providing a drier house environment.
Ammonia Control
Poultry producers traditionally use ventilation and acid-based
litter amendments to lower pH, bind litter nitrogen, sequester
phosphorus, and dry the litter cake. With respect to ventilation,
energy costs increase as ambient temperature decreases. While
acid-based litter amendments can be effective for the short-
term control of ammonia (NH3), this effect is typically short-lived
in the broiler house environment. The use of litter amendments
should provide the poultry producer a net benefit, by providing
lower mortality, in-house ammonia control and energy savings,
while meeting all environmental goals of the producer.
The use of Kemira Klasp Litter Amendment creates an improved
bird environment and enhanced overall general animal health.
Application Recommendations
A rate of 75-100 pounds of Klasp Litter Amendment per 1,000 ft2
of floor space is the typical recommendation for the treatment
of broiler litter. Lower rates (50-75 pounds per 1,000 ft2) may be
used during summer flocks. Higher application rates (100-150
pounds per 1,000 ft2) may be required under extreme conditions.
Rate selection for each operation will depend on current
management practices and needs, based on factors such as litter
reuse, short layout periods, ventilation control and existing litter
moisture levels. Klasp Litter Amendment can be safely applied
with birds in the house to address management issues that occur
post-placement. An authorized Klasp distributor can provide
rate recommendations that meet individual needs and goals .
University trials and field testing indicate that
poultry litter treated with Klasp™ Litter Amendment
results in:
Lower house ammonia levels •
Lower litter pH levels •
Drier houses with extended product •
activity and performance
Increased nitrogen content •
and improved litter value
Enhanced application flexibility •
and time management
Reduction in ventilation requirements •
and auxiliary heat consumption
