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
