Grower response to these economics vary widely as do their individual fiscal circumstances. Growers with low debt in land and equipment are more likely to plant even with a poor price outlook because their cost structure is more favorable. Those who rent land or have a mortgage, or have high fixed costs due to equipment will have a very difficult time making a profit this year. However, they still need to farm to service their debt. So, economics of the crop do not exclusively dictate planting decisions.
Water supply is probably more important.
