Brian Moorhead joined Lincoln Agritech in 2000 and specialises in optimising agricultural/horticultural land use and minimising negative environmental effects.

He provides technical support and manages large scale operations for numerous projects on the hydrology and nutrient dynamics in the soil – vadose zone – groundwater continuum. Soil coring, sampling, stream flow gauging, streambed sampling, groundwater and stream sampling and GPS applications are just a few of Brian’s many invaluable contributions to field site investigations.

Brian was recently awarded the prestigious NZ Soil Society of Social Science L.C. Blakemore Award. This award is presented only once every two years and recognises outstanding achievement and performance in soil science technical support.

He specialises in:

  • Managing field site investigations
  • Technical support and engineering solutions
  • Health and safety
