Tailor-made biological fertiliser solutions
Our customised approach ensures that each blend of BioFish™ N /NPKS meets the unique needs of your soil, pasture and crops, enhancing overall farm productivity. By targeting the specific deficiencies and requirements of your farm, we help optimise plant health, improve yield quality, and support sustainable farming practices.
We can add additional key nutrients (NPKS etc) to our biological baseline fertilisers, creating a specific mix to maximise the performance outcomes for your farm (see input list below). Independent soil and herbage testing is undertaken to identify the nutrients required for the final product recipe solution.
Results

Just 8 weeks after a single spread of BioFish™ N in Mid Canterbury, this farmer saw a noticeable transformation. Pasture density increased, the colour deepened to a rich green, and growth rates picked up significantly — all without relying on synthetic nitrogen. The improvement in plant health was clear, boosting feed availability and supporting better grazing rotations. It’s a strong example of how BioFish™ N can deliver fast, visible results in real on-farm conditions.
From winter through to spring, one application of BioFish™ N delivered a noticeable lift in this North Canterbury paddock. Pasture became denser, the green intensified and growth rates improved without synthetic nitrogen inputs. As the slider shows, stronger plant vitality translated into more feed on hand and more reliable grazing. This is real proof of how BioFish™ N activates soil biology and lifts pasture performance quickly.
It’s notable how lifting the biomass and performance of the soil microbes can lift soil fertility, and this is one reason I suggest BioActive Soils products.

BioFish N is a purpose-built biological fertiliser that delivers real results for dairy operations. It helps transform pasture quality quickly — often in as little as 8 weeks — by enriching soil biology and boosting nutrient uptake. The result is dense, nutritious feed that supports healthier cows, stronger milk solid production, and more profitable farming.
With a longer growth window than synthetic alternatives, BioFish N requires fewer applications, saving you time and input costs. It’s also nitrate-safe, helping you meet environmental expectations without compromising productivity.
If you’re looking to improve milk quality, animal health, and long-term sustainability, BioFish N is made for your farm. Book a free on-farm consultation to get started.
