How even is your spread?

The vast majority of fertiliser spreaders deliver highly varied spread patterns. Accu-Spread evaluates spread patterns from broadcast spreaders to help achieve an even result.
A new machine is no guarantee that an acceptable spread pattern will be achieved. Most spreaders do not provide acceptable uniformity of spread at the typical bout […]

Tissue testing tells….

Plant tissue testing helps ensure fertiliser responses are not compromised by factors we can control.
How effective was the fertiliser applied?
Tissue testing tells a lot about the effectiveness of different fertiliser treatments. The effectiveness of one product compared to another, or one strategy versus another is ultimately determined by […]
