BioAg Ammonium Sulphate

BioAg Sulphate of Ammonia (SOA) provides a cost-effective source of both nitrogen and sulphur and is ideal for use in biological cropping systems. It contains a minimum nitrogen content of 21%, presented as ammonium (NH4), and a sulphur content of 24%, presented as sulphate (SO4). BioAg SOA has the consistency of raw sugar and is applied using a belt spreader. SOA is less susceptible to volatisation than urea, allowing increased time before incorporation.

BioAg SOA is ideal for use as part of an integrated BioAg Fertility Program to rejuvenate natural soil fertility. Your nearest BioAg Fertility Specialist can develop a custom-made fertility program for each paddock or crop using advanced analytical services. Each program typically includes a range of BioAg solid and liquid nutrients, often in association with conventional inputs.
