First, on the cashflow issue, it's a transition problem being recognized. It's essentially a first-year problem, because once you've done it, you've simply shifted when you'll bank. You're going to buy those things next year anyway.
It is a serious problem in the first year, but we have managed to move.... We started off with 20% of our fertilizing-buying membership. We have now moved half of it off-season, and it's one of the key strategies we've used to lower their prices.
As for the companies, right now they do drive the prices down in those seasons, because it's the off season. I think that will continue simply because of practical realities. Most of the world is never going to shift to buying off-season, so we'll still probably be able to gain some serious benefits there.
But it's not an ongoing problem. It's a transition problem for which the government could, by moving cash advances or making a loan program for that first year, actually give help to farmers to shift to buying off-season.
