Application rates and water usage have long been problems many contractors and growers have had up until now. Current application methods for silage inoculants have proven to be very inacurate and often very costly.

Grevillia Ag has the answer to all of these problems with the “Air-Tech Wireless Controlled ULV Applicator” for applying silage and hay inoculants. By utilising Air Atomization technology, inoculant and compressed air are introduced at a nozzle resulting in an ultra fine mist.

When mounted in an enclosed section of the chopper or baler this ultra fine mist provides excellent distribution of active bacteria at very low rates, therefor requiring less water and a more cost effective method of applying inoculants.
