This "New theory" was based on the fact that an average farmer owns about 10-15 rai of farm land,
this total amount of land should be divided into 3 parts for the following functions:
Part 1:30% of the total farm area is reserved for water reservoir. The pond should be built at 4 meter deep with capacity to hold 19,000 m3 of rain water. This amount of water would be enough for agricultrual use all year.
part 2: 30%+30% of the total farm area are the agricultural land which is further divided into 2 sections.
The first half is paddy rice and the remaining is field crops or fruit trees depending on the condition of land and market
Part 3 : The remaining 10 % of the total farm area will be used as residential area, roads, dikes, draining canals as well as for family gardening and animal husbandry
The 30:30:30:10 formula suggested by His Majesty became the "New theory" of principle agricultural land management as follows:
1. It is practical to be used at small farm not larger than 15 rai
2. The land management of this type would result in self sufficiency of the farmers. Each family would be able to live comfortably while community co-operation and participation are the main element for success.
3. The main objective is to produce enough rice for the family to consume all year.
