Your yield per rai is up the climate in the end too much water not enough water, you take your chances it is not a big money maker after fertilizers, planting costs, maintenace costs, harvesting costs ,which is a big one,transport to the rice mill,and don't take your truck and ruin it, and depending on whats left, the relatives or wife takes the rest. Lucky to get your money back never seen a farang get a fair return on his ''gift'' to plant rice in the Isaan. In my 19 years of coming to Surin..... But if you have a big heart and a bigger wallet GO FOR IT....just don't complain when the harvest is in......Think1 DeadHorse2
