EVERY year farmers use large quantities of superphosphate with cereal crops to overcome the inherent phosphate deficiency of West Australian soils.
The increase in the average rate used by farmers reflects the increasing amount of new land being cropped.
Good seasons and favourable economic conditions may also have influenced super rates.
