This slightly strange looking machine is a converted Matrot sprayer with a Duport spike-wheel injector, currently used by Yorks contractor Inject Direct.

Using some new technology developed in Germany, the principle of injecting ammonium direct into the plant’s rooting zone is reckoned to slash fertiliser bills by 15%.

By adopting this approach growers can avoid leaf scorch, apply fertiliser in windy conditions and limit losses through volatilisation.

From the contractor’s perspective, there’s the opportunity to swap between the standard spray boom and the injector, doubling the machine’s potential workload.
