Spray and Fertiliser Application

We have a long history of developing systems for the measurement, testing and traceability of sprays and fertilisers which are applied both topically and aerially to agricultural and horticultural land. 

 

35 years of research, beginning at Lincoln University, has generated a wealth of experience, and purpose-built field tools to offer increasingly accurate pictures of the application process. 

 

This research assisted crop and food safety assurance and the continuing development of new machinery and spreading systems.

With the New Zealand Groundspread Fertilisers Association, we developed the SpreadMark code in 1995. 

 

Russell Horrell has now formally retired from Lincoln Ventures Ltd but is continuing to operate the calibration business under the name Ag Cal NZ Ltd.
