  • FEED
    This is the most effective point of addition. Many farms have eliminated most of their odor by feeding between ˝ to 2% of the total ration on a weight basis of BRZ™.   A 14 x 40 or a -40 mesh product should be fed in mash or a -40 mesh should be used to pelletize supplements.

    A thin layer should be applied to the bedding area or to the area that receives the manure each time it is cleaned out.

    The compost or dry stacked manure should be “top dressed” with a thin layer of BRZ™ after it is turned or after the addition of a new layer of manure. Alternatively, a layer of BRZ should be placed in the area of the barn receiving the fresh manure. Composting is an important process that (1) converts organically bound nitrogen that is not plant accessible to ammonium hydroxide, ammonium nitrate, and ammonia that then are plant accessible, (2) kills the pathogens, (3) reduces or eliminates the odor, (4) dries the manure, (5) reduces the flies, and (6) kills weed seeds. Composting should be conducted “in vessel” to prevent groundwater and air pollution. Wash down operations are no longer environmentally acceptable due to groundwater pollution of nitrates, nitrites, and hydrogen sulfide.


According to Lobo (1999, Feed Management, V.50, No.8, p.16-17) in 1998 layers and broilers consumed 44 million tons of feed in the United States.





BRZ™ increases and fixes the nitrogen in the manure and compost so that it is plant accessible but not water-soluble. It stops the gassing of the nitrogen as ammonia. Good chicken compost should sell for $75.00 to $90.00 per ton. Many of the areas that have been repeatedly fertilized with chicken manure now have phosphate problems. This is a result of not enough nitrogen to balance the plant uptake of the phosphorous. The problem can be solved by increasing the nitrogen, by the addition of phytase to the feed, and by feeding BRZ™ to solublize the phosphate in the bird.


The introduction of BRZ™ with the manure or compost to the soil has the benefit of increasing water retention, holding the nitrogen and other nutrients in the growth zone, provides a medium for the future capture of nitrogen, increases the ion exchange capacity of the soil, provides potassium and calcium, and enhances infiltration and aeration of the soil. BRZ™ is a value added soil amendment that should be advertised as such.

    Reduces the ammonia gas and odor in the coop and manure storage and compost areas.

    Reduced ammonia gas and increased moisture absorption helps control flies.

    Fixing the nitrogen and various heavy metals reduces the pollution of the groundwater with nitrates and nitrites.

    Egg wash water can be recycled after filtration through a bed of zeolite granules to remove suspended solids and bacteria (e.g. E. Coli, etc.).

As currently defined for the Environmental Protection Agency (EPA) regulations concerning Concentrated Animal Feeding Operations (CAFO’s), caged layers with wet (wash down) manure handling have a different classification than caged layers with dry manure handling as shown in Table 1.

Table 1. Comparison of EPA and USDA Definition of Number of Animals in 1,000 Animal Units.

(from EPA Cost Methodology Report for Swine and Poultry sectors, 2001)

Layer (wet manure)



Layer (dry manure)









According to EPA, there are an equal number of wet and dry caged layer facilities with > 1,000 Animal Units in the U.S.  Most of the wash down manure caged layer operations are in areas of the south where freezing (<28oF) occurs infrequently.

Assumed Food consumption and Manure Production

  • Caged layers daily consume 2,000-2,600 lbs of feed per day per 100,000 head and daily produce
    2,000-  3,400 lbs of fresh manure (moisture @ 70-80%).

  • Total nitrogen content of fresh manure averages 1.5-2.0 % (@50-70 % moisture), but initial ammonium
     concentrations are only about 0.57-0.77 %; the remainder is organic-bound N.

  • Therefore 1 million hens will produce 10-17 tons of fresh manure (@ 70-80 % moisture) daily.

Wash down Manure Handling and Properties

  • Liquid slurry (in ponds or lagoons), after 6-12 months storage typically contains 62 lbs of total N, 42 lbs of which  is ammonium per 1,000 gallons.  At a value of about $0.35/lb of N, each 1,000 gallons has a nitrogen nutrient value of  $22. If injected into soil as liquid, it has about 80% N availability to plants the first year.

  • Associated anaerobic lagoon sludge typically contains 26 lbs of total N, and 8 lbs of this is ammonium N per 1,000 gallon.  The value of N in this sludge is about $9 per 1,000 gallons.  If injected as liquid, it has about 60 % plant availability in the first year.

  • Anaerobic lagoon liquid typically contains 179 lbs of total N (154 lbs of this is ammonium) per acre-inch (of liquid in the lagoon).  When injected in the soil as liquid it has 90 % plant availability.

  • Many operations will be required to have covers on the lagoons to minimize heat and associated loss of ammonia (gas).

  • Addition of zeolite to the fresh manure in small amounts would provide the best chance for capture of ammonium because fresh material has the highest ammonium N concentration.  After washing down, the ammonium concentrations in the liquid is very diluted.

Proposed Environmental Protection Agency (EPA) regulations concerning Concentrated Animal Feeding Operations (CAFO’s) will force several changes in all large animal/poultry farms in the United States within the next few years. Several states have already passed statutes concerning regulation of CAFO’s.  The present abbreviated report was prepared to formulate methodologies or approaches to achieve compliance with the proposed regulations in the most cost-effective manner without significant interruption of current operations for caged layers used in egg production.  A major part of the proposal relates to integrated use of natural clinoptilolite (a mineral of the zeolite group) for improving poultry health, reducing ammonia emissions from manure, retaining nitrogen in poultry manure, and thereby producing a poultry manure product that is valuable as fertilizer and soil conditioner.  The CAFO regulations include handling and treatment of water used in egg-washing.

  • Reduce ammonia gas (NH3) generation in caged layer residence and manure storage facility by capturing ammonium (NH4) by ion exchange into zeolite.  This is accomplished by adding a small amount (e.g. 1 wt. %) of zeolite to the layer feed, and adding a small amount (to be determined) of zeolite to fresh manure.  Capture of ammonium by zeolite addition to feed occurs in the gut and some ammonium present in the feces is exchanged into zeolite added to the fresh fecal material.  The exchange of ammonium into the zeolite protects it from nitrogen (N) loss by alteration to ammonia gas or other gaseous nitrogen forms. 

  • Reduction of ammonia generation from fecal material will reduce noxious odors and thereby minimize attention of flies and reduce atmospheric generation of  particulate matter (PM10)10-micron-sized particulate nitrogen-bearing salts that interfere with respiration of  humans, poultry, and animals.  Ammonia emissions from litter have been found to be a source of ammonia pollution in acid rain in Europe.
  • Isolate and age manure in anaerobic conditions using silo bag containers to enhance heat generation in order to destroy potentially toxic pathogens, minimize N loss to atmosphere, eliminate rainfall transport of nutrients and pollutants to the watershed, and remove odor exposure to the local environment.  This isolation might be used to precede composting, either on-site or off-site, depending upon whether or not it is desirable to emit strong odors on-site.
  • If composting is desired, aerobic (oxygen-using) conditions are necessary to support and enhance microbial activity; this requires blowers or fans, or turning the compost with a front-end loader or a commercially available compost turner.  Temperatures in the compost must be maintained at levels above approximately 130oF (but lower than 150-160oF) in order to kill any pathogens.  This composting will expose the manure to the atmosphere and allow odors and ammonia gas to be emitted locally.
  • Ion exchange of ammonium from the fecal material displaces potassium and calcium from the zeolite and these plant-essential elements will be available as nutrients in the manure.
  • Introduction of zeolite-plus-manure to the soil will have the beneficial effects of enhancing water retention, increasing ion-exchange capacity of the soil, providing a medium for future capture of ammonium nitrogen, and increasing aeration properties of the soil due to the high internal surface area of the zeolite.
  • Egg-washing water can be recycled after filtration in a zeolite bed to remove suspended solids and to trap bacteria (e.g. ecoli, etc.) in the zeolite pores.

  • Phytase added to the food would improve phosphorous utilization, and thereby minimize phosphorous pollution in the fertilizer application.



  • Caged layers daily consume 2,000-2,600 pounds of food per day per 100,000 head and daily produce 2,000-3,400 pounds of fresh manure (moisture @ 70-80 %).

  • Total nitrogen content of fresh manure is 1.5-2.0 % (moisture @ 50-70 %), but ammonium concentrations are only about 0.57-0.77 %.  [The remainder of nitrogen is in organic nitrogen compounds where nitrogen in unavailable for plant nutrition until the nitrogen is converted to either ammonia, ammonium, nitrate, or nitrite.]
  • Therefore 3.5 million hens will produce 35-59.5 tons of fresh manure (moisture@ 70-80 %) daily.


For caged layers the average concentrations of  N, P2O5, and K2O in fresh manure @ 60% moisture are:

N   = 1.8 %
P2O5 = 2.0%
K2O = 1.0%

At 50 % loss of N prior to field application and values per pound @ N = $0.35, P2O5 = $0.23, and K2O = $0.15, the value of the poultry manure contribution nutrients @ 30% moisture after dry stacking is:

N =   $ 12.60
P2O5  = $18.40
K2O  =   $6.00


Total =$37.00 per ton + 25%

*This value of the plant nutrients does not include the value of the K in the clinoptilolite.
