abc radio : food scarcity, page-14

"browny - phosophate is demand and supply seperate from oil u are right.

Food prices are influenced greatly by the oil price why well farmers use oil in their machines, transport costs are a large part, inflation from oil drives up the cost of moving and farming. So food is about 25% linked to the oil price as a cost of produciton. The prices were mentioned probably because they are another input cost in farming. biofuels stil take fertilizer to product they are just an oil alternative."

I didn't say that SB. IMO phosphate demand in linked to the oil price. Simply put if the oil price stays high=increased demand for crops to be used for biofuels = increased amount of crops being planted =more phosphate needed. Added this to people eating more in china/india and you can see why the price of rock phosphate has gone to $400/t and doesn't look like coming down anytime soon.
