Matt Rout

Waikato dairy farmer

Since using AgriSea we've noticed a dramatic drop in somatic cell counts, getting as low as 93,000 whereas before we were always up over 300,000.

Nathan Gardner

Northland dairy farmer

Since converting, our facial eczema spore count levels dropped from 350,000 down to 15,000, even when counts in the district were up to 500,000.

Nick & Jo Collins

Piopio farmers

Agrisea Foliar Nutrition promotes flowering and the development of fruit. There is more fruit sized-up, the pack out is better, there are less fungal issues, the leaves are larger and greener. Overall we have a healthier orchard.

Scott Byles

Western Bay of Plenty avocado grower

Every season we have exceeded our weight gain targets, but this has always come at a cost. When we called Gavin [AgriSea] in, and when he gave us his recommendations, it all seemed to make sense... the performance of the property has been outstanding.

Finding the sweet spot: how Chris Parry grew production with fewer cows

Chris Parry reduced cow numbers from 285 to 228 and still increased production from 71,000 to over 100,000 kg of milksolids. Instead of pushing for more inputs, the shift came from focusing on what was happening beneath the surface, in the soil.
