The Hydro Equalizer Manifold from Hydro Engineering Inc has been designed to provide an even manure application flow rate, while reducing plugged outlets. The company’s goal was to come up with a cost-effective, nearly maintenance-free product.
The Hydro Equalizer Manifold was developed to deliver equal amounts of manure to each injector on a drag hose injection toolbar or manure tank wagon injection toolbar. As the rotating equalizer turns, it feeds each outlet. Plugging is reduced because the manifold is designed to perform with fast, even pulsing flow to each injector, regardless of gallons per minute (gpm) flow to the manifold. The manifold can accommodate from 200 to 2,000 gpm and only utilizes five to seven lbs/sq inch (psi) pressure.
The replaceable Equalizer shearing edge is made of heat-treated, tooled steel. The Hydro Equalizer Manifold can be put on existing manure tanks and toolbars, and ranges in price from $1,800 to $2,000.
Overall, the tool helps increase the value of manure as a fertilizer resource by making it easier to achieve uniform application rates. Uniform manure application is a critical component of a good nutrient management plan and can help producers deal effectively with environmental concerns.
Regardless of whether it originates from cattle or hogs, slurry contains inexpensive but valuable ingredients for improving the fertilizer content of soil. Injecting slurry into soil with the Vibro Injector from Kongskilde ensures that the slurry is immediately fixated within and covered by the soil. The slurry is injected into the ground immediately behind the heavy-duty Kongskilde tines. Due to tine vibration, the soil is loosened into small particles, which improves uptake and binding of the slurry with the soil.
The injection depth of 4” to 6” ensures that the slurry is 100 percent covered by soil. By doing this, the evaporation of ammonia gas is minimized to just one to three percent. This means very minimal loss of nitrogen and no unpleasant smell, says the company.
The working depth is always beneath the planting depth so the slurry elements are immediately available for root development.
A hydraulic powered distribution box on top of the Vibro Injector provides a regulated distribution and constant flow of slurry, independent of the working speed.
A range of working widths is available for use with a tractor or slurry tanker.
AerWay is introducing a state-of-the-art Slurry Splash Hood system that will be available this spring. This new design will join the AerWay family, which already includes the award winning SSD Manure Management System.
The Splash Hood system is a bolt-on design that can be mated to AerWays ranging in size from 10’ up to 20’ in working width. It includes a patented swing pipe assembly that eliminates the need for complex and expensive swivel hitches. This pipe can swing freely through an arc of over 200 degrees while the machine turns.
The distribution head feeds two or four Splash Hoods that can be adjusted in height based on ground cover conditions and flow rates. The Splash Hoods are computer optimized to provide an even and controlled dispersal of the slurry in front of the Shattertines. The unit can accommodate a knife valve shut-off as well as a flow meter.

Houle has designed a tool bar to handle thick, heavy liquid manure. The 38’ tool bar with three deflectors has been developed by Houle in Eastern Canada, where dairy and hog producers have to comply with new air quality regulations and, at the same time, keep the cost of manure management low.
The 38’ tool bar handles hog and dairy manure containing long bedding. It is compatible with the renowned Houle centrifugal pump, which guarantees uniform, fast spreading of heavy liquid manure at a rate up to 1,800 US gpm.
To reduce odors, liquid manure is applied by gravity thanks to three adjustable deflectors fed by 6” and 8” discharge pipes. All tool bar articulations are made of steel, eliminating any risk of hose clogging and breakage. The spreading width is quickly and easily adjusted from the tractor cab by means of hydraulic controls.
The 38’ tool bar with three deflectors is designed for custom spreaders and livestock producers who want to spread any liquid manure fast, in all types of fields.
The Bourgault Liquid Manure Injector or LMI was developed to inject liquid
manure into the soil in a low disturbance manner. The 24” coulter of the LMI is mounted on with a tow-in angle that opens a furrow, enabling high rates on liquid manure to be placed. Pooling of the manure is minimal and odor is also minimal. The low disturbance of the coulter leaves fields smooth and undisturbed, which is desirable for those farmers that utilize minimal tillage practices. The LMI operates in cultivated fields, standing stubble and performs extremely well in hay and pasture land, according to the company. These coulters can be found operating behind pull type tanks, self-propelled tankers, and umbilical cord units.
The Avenger coulter places high volumes of liquid manure and other liquid nutrients deep into the soil with controlled soil disturbance and minimum loss of ground over. The specially designed 25” blade is set at a five-degree angle to cut a deep path through tough grass or crop residue. The trench is widened further by the scraper blade in front of a large 3” drop tube for high volume injection. The Avenger system is spring-cushioned to reduce bounce and ensure consistent placement. Optional sealing discs or wheels are available. The Avenger fits 5” by 7”, 6” by 6” or 7” by 7” toolbars. It features a heavy-duty cast hub and tapered roller bearings for long life.
The benefits of the Avenger are said to include a requirement for less horsepower than conventional shanks, leaving the field ready for no-till, great for side-dressing manure, run-off control, reduced draft compared to shanks and it does not reduce surface crop residue.
Veenhuis yellow equipment is not only seen on the European agricultural landscape but also on the US landscape. The company’s silage wagons, slurry spreaders, tanks, transport and weighing systems are a symbol of quality, durability and technical advanced equipment. The Holland- and US-based company has and is working hard to respond to the demand of farmers for more user-friendly equipment, and greater capacity and durability.
The Ecoject from Veenhuis is a professional slurry injector for modern dairy farming. The unit’s dual bearings and correct disc shape produce a rolling cutting movement of the solid disc. The independently moving elements that follow the soil surface level are mounted to a heavy-duty frame. This construction provides the machine with a high degree of reliability. As is the case with the company’s Euroject 250 and 350 models, the spacing between the discs is 190 mm. The slurry injector is fitted with a 60 mm slurry hose and 125 mm supply hose.
Slurry is evenly spread thanks to the custom shaped outflow rubbers on the Ecoject. The machine’s discs are 250 x 20 mm for the Euroject 250 injector and 350 x 20 mm for the Euroject 350 injector, it has two elements for following track and soil, and it features large axle travel and each outflow is fed individually for regular distribution. The machine features a hydraulic shoe shutoff valve and it is hydraulically foldable. The arable injectors are available with a variety of attachments and are mounted to a heavy-duty frame with leaf springs to allow the maximum flexibility to prevent breaking and bending of the cultivators.
GNE Distributing of Visalia, California handles the Veenhuis equipment line in North America.
Balzer Inc is pleased to announce a new addition to its vacuum spreader line. The Balzer Eliminator sports an 8” electric over hydraulic controlled loading boom, so the tank can be loaded without the operator leaving the tractor seat.
Options include slurry impeller discharge, steering rear axle, flotation tires, hydraulic top hatch, and various rear mounted injectors.
The trend has been to off-road manure spreaders and nurse them with semi-trailers, says the company. The majority of Eliminator owners run two to four semi-trailers to one spreader. Fill times run three to four minutes for a 6,500 gallon unit.
Many concerns are raised by large animal feeding operations with concentrated manure, such as amount and quantity of pathogens present, odor, heavy metals, run-off, loss of nitrogen and phosphorus pollutants.
Ag-Chem Equipment Company has developed one solution: the Nutrient Management System. The company uses the latest Global Positioning Systems (GPS) combined with state-of-art GIS software called SoilTeq Geographical Information System (SGIS), developed by SoilTeq, and Falcon II computer controller to match crop nutrient requirements to the nutrient makeup in the manure.
This fully integrated system is a four-step process. In the first step, data such as manure nutrient content, soil grid tests, yield goals, and soil surveys is
This information is critical to establish the base line for the nutrients to be applied to each of the fields.
In step two, through SGIS and local agronomy recommendations, a manure application map can be created. This map will indicate the precise amount of manure to be applied across the field for crop nutrient requirements. Where limitations of manure nutrient content exist, commercial fertilizers can be injected into the slurry or variably applied to make up the difference. In addition, no apply zones or buffer zones can be included in the application map. For other biosolids, which contain metals, a map can be created to the desired level to be applied.
In step three, the manure is then variably applied from 1,000 gallons per acre up to 25,000 gallons per acre and directly incorporated in one pass through the use
of the Falcon computer controller and GPS located on board the Terra-Gator 3104 or 9105 NMS machine.
In step four, the Falcon computer controller also generates an electronic record of what, when, where, and how much manure was applied. This “as applied” report can be used for further agronomic analysis or compliance records.
DM Machinery Inc, an innovative Quebec-based manufacturer specializing in material handling of liquid manure, has developed new standards of injecting liquid manure.
The Sub-Soiler is mounted to a three-point-hitch hydraulic back rack attached
to the rear of the liquid manure spreader. Manure being supplied by the pump flows through an adjustable diverter flow recirculation valve. It is then forwarded to a distribution box mounted to the Sub-Soiler then in turn to the rear of the injection shank attached with a 7” sweep and a forward cutting coulter.
The Sub-Soiler maintains its injection level by means of two gage wheels, in conjunction with an adjustable pressure relief valve. This equipment may also be removed and used for deep tillage. DM Machinery offers four, five and telescopic six-shank Sub-Soiler injectors.
Farmstar announces their new 30‚ No-Till Direct Injection Bar. The bar comes standard with 11 No-Till trip type shanks on 30” centers with 23” diameters. Coulters on the unit eliminate trash build-up. Each shank has product supplied from a timed manifold through 3” diameter drop hoses, insuring consistent product delivery to each shank across t
The bar is a winged type to accomplish ease in portability, along with operator choice, and has a six degree negative fold during field operation. Four adjustable gauge wheels are also included in the heavily constructed bar. Mounting is via a Class III, three-point hitch.
Available options include a double pivot with telescopic stops, hose swivel, Raven monitoring system and GPS mapping for tracking application rates and values. The new bar helps reduce fertilizer costs while insuring even distribution in the plant bed.
