Ravensdown is to cap its superphosphate price at $367 a tonne until May next year. Ravensdown sales and marketing manager Gary Bowick says unprecedented changes across the globe that are impacting supply and pricing is the main reason. With the northern hemisphere’s spring demand yet to kick in, international supply is complicated by the high price of natural gas and countries restricting fertiliser exports, so demand for fertiliser even at elevated prices is expected to remain. Ravensdown along with Ballance Agri-nutrients also announced new prices for its other fertiliser. Ballance general manager of sales Jason Minkhorst says pricing and supply of fertiliser are being impacted by very high demand constrained supply caused by very high energy prices and the fact that China is limiting exports.
