Nonsense.
Thais can and do plant up to three crops a year, we do.
First crop covers fertalizer, seed, fuel, etc.
Second and third harvests will hopefully be profitable.
Poor water management and lack of maintenance of water storage/delivery is the culprit.
Thais will continue to plant there rice,sugarcane,etc., whether it fails or not because they'll recieve a subsidy of 500-1000 baht a Rai for failed crops.
