All farmers have certain fixed costs. Additionally there are then costs for actual cultivation.
Farming Costs Per Rai
These costs per rai of farmed land = approximately 21,000 thb
* Note 1 rai is 1600 sq m but only 1200 sq m is actually available for farming.
This means that 1 sq m must produce 17.5 thb per month. We consider that you should aim at 100 thb /sq m in order to have a lucrative farm.
Most organic farmers are happy to make 83 thb per sq m per month.
