Accelerator™ PLUS was developed to help reduce the crust that can accumulate in manure storage systems. The product contains enzymes selected for their ability to digest the outer layer of corn kernels and other hard-to-digest feed components, limiting the formation of pit crust on manure storages. By decreasing pit crust, livestock producers can reduce fly and rodent populations, reduce ammonia levels, and improve the worker environment.

According to Agtech Products, Accelerator PLUS is easy to use, inexpensive and technically supported.

Alken-Murray Corp.
Alken Enz-Odor® 5 is a concentrated dry blend of gram-positive Bacillus strains and vegetative, gram-negative strains of naturally-occurring non-pathogenic bacteria and other ingredients designed to liquefy, metabolize, deodorize and balance the nutritive value of swine manure. The product is suited for use in holding tanks, manure pits, drainage systems and lagoons. According to Alken-Murray, Alken Enz-Odor 5 has been specially balanced for the carbon:nitrogen ratio of swine and poultry manure to produce more usable fertilizer that will be better utilized by plants, resulting in reduced runoff. The company reports that Alken Enz-Odor degrades cellulose fibers, xylan, proteins, fats and residual carbohydrates in swine manure; retards odor generation by oxidizing compounds, such as hydrogen sulfide; is effective over a wide temperature and pH range, and is non-toxic and safe to handle and store.

AquaServe Technologies
AquaServe Technologies provide products aimed at reducing odors by increasing the population of beneficial populations of specific strains of bacteria.


The company’s manure treatment product reduces manure volumes by converting the waste into simple compounds. Bacteria strains are custom blended based on the needs of the customer and the company reports it is harmless to the environment, humans and animals. According to AquaServe, benefits of the product include reduced manure volume, reduction of odors, a drier manure, making it easier to handle the sludge and more efficient for composting.

AquaServe also produces a lagoon treatment product that controls pond scum and odor. The product is a blend of selected bacteria chosen for their ability to remove nitrogen from the water and to degrade organic compounds. The program does not include algaecides and consists of single regular treatments during the algae season.

Boss Technology
Agri-Boss™ is a bactericide additive used in the management of stored manure to help eliminate odors, liquefy solids and improve effluent quality.

According to Boss Technology, Agri-Boss works by blocking the anaerobic bacteria responsible for ammonia gas production and by lifting and suspending solids in the aerobic zone at the surface of the tank, stimulating the aerobic bacteria responsible for liquefaction of the waste material.

Agri-Boss increases the fertilizer value of the manure by preventing losses of nitrogen as ammonia gases and reduces fly populations by eliminating the solids needed for larvae development, the company claims.

General Environmental Science


General Environmental Science (GES) began developing and marketing bacterial products for water quality improvement in 1974. The company’s product line has since expanded to include a liquid product line, a gel-based product line, a series of specialty products, and automatic bacterial injection (ABI) delivery systems.

General Environmental Science's Liquid Live Micro Organisms (LLMO) product line includes six specialized bacterial formulations, each designed to degrade certain types of waste. A mixture of bacterial species is included in each product to provide optimum treatment efficiency. LLMO products can be poured directly into the waste to be treated or can be used with an ABI delivery system.

LLMO S-1 bacteria are specially selected to reduce organic solids, such as those found in hog manure pits and dairy and hog lagoons. These bacteria produce enzymes that convert organic solids into carbon dioxide and water. According to GES literature, within four weeks of initial application, the scum layer on the pit will begin to break up and the solids in the pit will be broken down to a level where the material can be easily pumped out. The company also claims pit odor can be decreased through use of the product.

GES’ GelPac of technology involves immobilizing bacteria in a slow release gel. When it’s added to the liquid, the gel slowly dissolves, releasing the GelPac bacteria to the waste stream. GelPacs are generally replaced once per month and must be used with an ABI delivery system.

Global Repair
Humicbloom™ is the newest product from Global Repair. According to the company, this natural concentrate helps to improve nutrient value and locks in ammonia in slurry tanks, liquid manure storage systems, and compost piles, reducing and eliminating odors. .

When Humicbloom is applied to soil, it allows plants to access nutrients already in the soil and intensify applied manure and fertilizer, states Global Repair literature, adding the product has been naturally processed. It can be added to other applications or used on its own.

Midwest Bio-Systems
Midwest Bio-Systems markets numerous additives for use in composting systems, including ACS N-Converter (helps break down organic matter and converts ammonia to nitrites and then nitrates), ACS Humifier (helps break down organic matter), and ACS Finisher (stabilizes any remaining volatile compounds).

Midwest Bio-Systems also supplies ActPak Extracted Compost Tea Activator. According to the company, ActPak helps to stimulate the microbes in the compost tea to become active and multiply, which benefits the crop on which the compost tea will be applied.

Penergetic products, such as Penergetic-g slurry treatment and Penergetic-k dry manure/composting treatment, can help to restore valuable organic fertilizers.

Penegetic-g optimizes slurry and liquid manure with the addition of oxygen, minerals, trace elements and herbs. This renders the slurry homogeneous and free flowing. The aerobic conversion process reduces floating and sedimentation layers and leads to a reduction in odor emissions. The incidence of scorching during application is reduced and the rotting effect is optimized.

Penergetic-k for dry manure and compost uses oxygen, saccharose, and fungi to promote the degradation of organic matter and accelerate the rotting process. The use of Penergetic-k reduces the unpleasant odor from compost and manure to a natural level. The actual composting process is accelerated and the end product (humus) is more valuable as a result of aerobic rotting.

Penergetic products are marketed and distributed in North America through Penergetic Canada.

Pit Boss®
Pit Boss® pit and lagoon treatment is a unique, pH controlled product, not an enzyme or a bacteria. It interacts chemically with waste constituents to boost the aerobic manure digestion process, resulting in accelerated solids breakdown and lower gas production. According to Tramfloc Inc., less gas and faster suspension of solids leads to reduced odor and highly liquefied waste, meaning efficient pump-out. Tramfloc recommends Pit Boss for more than just hog manure. The company claims the product can be sprayed on dairy bedding and poultry litter to help control fly larvae and deplete odor. In composting, Tramfloc states Pit Boss can help with odor and progress decomposition.

Pro-Act Biotech


Fertilizer costs, odor, solids, environmental restrictions – these are big concerns for farms when it comes to manure management. Pro-Act Biotech’s manure treatment system has been providing solutions to these problems for close to a decade.

With Pro-Act, the farm is left with better fertilizer, less odor, less solids requiring less agitation, and easily manageable nutrients that are stratified into accessible layers for use on growing crops. 

Increasing nitrogen fertilizer value while complying with nutrient management. Pro-Act’s system converts organic nitrogen to inorganic nitrogen for easy plant uptake while allowing much of the phosphorus to settle to the bottom. The top water in Pro-Act treated lagoons contains less than two pounds of phosphorus per thousand gallons. This allows farms to irrigate at least three times as much, supplying their crops nitrogen needs with manure water without the risk of burning their crops or going beyond phosphorus limitations.

Pro-Act Biotech’s microbes degrade the organic solids in the manure, keeping the lagoon in a healthy state that is more manageable.

Odor from a microbially-active lagoon is reduced dramatically, not only making farm life more pleasant, but keeping the neighbors happy.

Microbially-active flush water has less solids and odor than untreated water, leaving the farm with cleaner and less slippery barn floors, meaning better smelling barns and safer animals.

Roebic Laboratories
Roebic Manure Liquefier (RML) is intended for use in hog, dairy and beef cattle operations, including barns, confinement areas and feedlots. Specific applications include manure pits, slotted floor areas and any piping, drains, traps, pumps or equipment used for handling, moving and storing livestock manure. According to Roebic, RML helps to digest manure solids, reduce ammonia and sulfide odors, and improve manure liquidity while retaining the manure’s nutrient values.

Roebic also produces Roebic Manure Deodorizer (RMD), a concentrated liquid enzyme product used for reducing and controlling odors from animal waste. According to Roebic, RMD helps to eliminate odors in livestock buildings and wastewater lagoons, reduces ammonia and sulfides, and improves manure liquidity. It does not act as a perfume or masking agent.

Other Roebic products include Roetech 106, a concentrated mixture of six Bacillus bacteria used to liquify solids and reduce odors in livestock manure ponds and lagoons; and Roetech 106 PS, a combination of Bacillus bacteria plus Pseudomonas that provides a multiple enzyme producing culture for controlling ammonia and hydrogen sulfide while liquefying solids and reducing odors in livestock manure ponds.
