Timing is everything! This includes the best time to apply liquid manure to the field and crops. The cost of nitrogen, phosphorus and potassium to the farmer can be as high as $128.00 an acre plus the cost of UAN 28%.
Applying fertilizer to 1,000 acres will cost in excess of $128,000 / year. Taking into consideration that hog and cattle manure is applied in the fall and spring in order to empty the pits and lagoons, much of its nutrient value is lost.
Cadman has taken a concept brought forward by the Alig brothers of Ohio to design, build and market a new Continuous Manure Applicator (CMA) which is engineered to apply liquid manure via sidedress to row crops such as corn in fields as long as ½ mile.
The Alig brothers brought their patent pending concept and four years of data collected by Ohio State University to Cadman where they used an example of corn sidedressed with liquid manure once the corn was in the ground. The data concluded that the best time to apply manure is when the corn reaches between 2 to 3 feet in height.
The major reduction in fertilizer plus the average of an extra 7 to 10 percent in yield will give the customer a payback on the CMA, injector and swing arm of 18 months on 2,000 acres.
Why hasn’t this been done until now? Simple, it’s not reasonable to try putting a heavy tanker in 2 - 3’corn nor has it the storage capacity to venture down ½ mile longs rows.
“The CMA enables farmers to add manure during the growing season, which has proven to be a major advantage” says Wayne Cadman, President of Cadman Power Equipment. “The CMA does not compact the soil or damage the fields like tankers do. It also allows the nutrient to be injected when it is the most beneficial for the crop.”
The CMA carries up to 2700’ (823m) of hose, is available with a 30, 40 or 60’ injector and swing arm to continuously apply manure at a rate of 5,000 to 8,000 gallons per acre. Until now, farmers have been able to use soft hose drag and hard hose drag with tankers to apply manure but they could never apply after the crop emerged or the crop would be destroyed, hence the CMA. The tractor pulls an injector with swivel arm attached to it. The arm pulls out the 5.1” I.D. hard hose away from the CMA and injects 30, 40 or 60’ wide. When the tractor gets to the opposite end of the field, the tractor turns 180° and comes back down the field injecting another 30, 40 or 60’ strip. When the tractor turns, the swing arm - which is the same length as the injector - swivels on a pivoting wheel at the end of the arm and the hose returns to the CMA in the same row that is was pulled out.
The tractor ground speed on the return trip is synchronized with the rate of speed that the CMA rewinds the hose. The operator controls the 4WD CMA reel and steering remotely from the tractor cab. Before the operator completes his return trip, he remotely moves the CMA forward another 60, 80 or 120’ in order to start another pass.
Cadman is now taking orders for spring delivery.
