Slurry spreading with precision

Vervaet’s hydro-trike slurry spreader was developed in collaboration with contractors nearly twenty years ago. As its name suggests, it’s a three- or five-wheeled, self-propelled machine, which offers up to 20,000 litres in capacity. And, even the five-wheeled option is built with soil health in mind.

“So each wheel has its own track to minimize soil compaction — obviously, the more wheels in the same track, the more you compact the soil,” says Robin Vervaet, in an interview with RealAgriculture’s Shaun Haney. “Plus, of course the tri- configuration makes the machine extremely maneuverable.”

When in the field, one set of duals on the five-wheeled machine move out, allowing each to have its own track. Vervaet says this puts it above its pull-type counterparts when it comes to minimizing soil compaction.

In addition, the unit now offers a precision application aspect.

“John Deere designed a NIR sensor…which can actually measure all the contents of the slurry — phosphates, nitrates and so on,” says Vervaet. “So actually, we can make the pump adjust itself when the amount of nitrate changes in the slurry, so that the amount that you put on the field is always exactly the same.”

Stay tuned for an upcoming TechTour focused solely on John Deere’s NIR real-time manure nutrient sensing technology.
