Get soil temperatures up fast for a strong start to pasture growth
BioFish™ N Spring Start is formulated to help lift soil temperatures quickly and encourage strong early-season pasture growth. By supporting active soil biology and targeted nutrient availability, it helps pasture bounce out of winter faster, improving pasture density, colour and feed quality when seasonal demand is at its highest.
Build healthier soil that’s more resilient to both pests and dry conditions
Healthy, biologically active soil is better equipped to support strong root systems, hold moisture and recover from seasonal pressure. BioFish™ N Spring Start works with the soil to improve biological activity and pasture resilience, helping reduce vulnerability to common pasture pests such as grass grub and porina, while also supporting stronger moisture retention through dry conditions.

Local value for local farmers. NZ owned and based.
BioFish™ N Spring Start is locally made and developed for New Zealand farming conditions. As a New Zealand owned and based business, BioActive Soils understands the seasonal pressures farmers face and offers practical, biological fertiliser solutions designed to support local farms.
Available from $897 per tonne, BioFish™ N Spring Start offers strong value for farmers looking to get pasture moving early, support healthier soils and plan ahead for the season.
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.
