PDF specification sheet 88.8KB
Hygroscopic in nature so must be stored under cover and away from moisture to retain free-flowing characteristic. The product is likely to have lumps, which will break up relatively easily with a front-end loader. Must be broadcast to a width of 8m
Physical Properties - Western Grade
PDF specification sheet 88.8KB
Free flowing semi-granulated, no lumps - flows like ordinary fertiliser, can be stored in silos, augered & put through an air seeder. If spread, spreads to a width of 14-16m.
Stowage factor
1 tonne per cubic metre.
Associated benefits of SOA
- Stability of SOA gives advantages to the farmer.
- Reduction in volatilisation when compared to urea.
Note: Wet calcareous soils are an exception. - Increased in time before incorporation.
- Greater efficiency of nitrogen (N) uptake reflected in improved gross margins
- 24% Sulphur
