Metalform’s Tow and Fert fertiliser applicator.
Technology developed in Dannevirke is becoming disruptive in pasture grazing markets beyond New Zealand.
Tow and Fert, designed and manufactured by Metalform, has the ability to either reduce fertiliser input costs without impacting pasture yields, or maintain fertiliser inputs and improve dry matter and protein production.
Norco Rural, a dairy co-op in NSW, is the latest company to prove the efficiency of nitrogen when applied in a foliar form.
During trials it applied nitrogen at only 42% of the typical rate – 21kg/ha of foliar-applied urea versus 50kg/ha of granular urea.
Measurements were taken over nine grazing cycles; the DM/ha yield during seven of those cycles showed an increase in yield from the lower application of nitrogen.
Profitwise, on a 150ha farm milking 400 cows, a typical application of granular urea at 80kg/ha six times a year would equate to about 72 tonne of urea, costing $43,000. But if it were dissolved and applied as a foliar spray, the cost would be around $18,000, saving $25,000 annually.
From an environmental viewpoint, N escaping into the environment as ammonia, or leaching beyond the plant's root zone or escaping to atmosphere in the form of nitrous oxide, would be cut drastically because the urea would not enter the soil but be directly absorbed by plant leaves.
Metalform developed Tow and Fert, a fertiliser applicator, to quickly dissolve normal granular urea in cold water on the way to the paddock, thereby turning urea into a dissolved foliar spray quickly, conveniently, cheaply and in an environmentally responsible way.
With specific agitation patents and boom recirculation technology, the Tow and Fert dissolves soluble products and can keep insoluble products like fine lime or RPR in suspension; this allows an operator to make one-pass applications of, say, weed spray, humates, gibberellic acid and even small seeds.
DairyNZ has pulled together tactics that will help farmers improve on-farm efficiency and have positive benefits for the environment. These tactics are based on research, data, and lessons from leading farmers.
