Part 1: 30 per cent of 10-rai piece of land (about 3 rai or 0.48 ha) is used for a reservoir. This should be dug to a depth of four metres for a capacity of 19,000 cubic metres of water collected from rainfall, which will be enough to irrigate the crops throughout the year. On his many visits to his people in the rural areas, the King has always stressed the importance of water to agriculture, especially to the rice crop which thrives on water. Since building large reservoirs is becoming more and more difficult due to the expanding population and the decrease in the amount of land available. The King advocates the building of household reservoirs. These, apart from providing water for the crops, can also be used to raise fish and aquatic plants, thus adding to the household income.
Part 2: 30 per cent of the land (about 3 rai or 0.48 ha) is devoted to rice cultivation which will produce enough rice for the household needs.
Part 3: Another 30 per cent of the land ( 3 rai or 0.48 ha) may be used for growing more rice or horticultural crops, depending on the local conditions and the market demand.
Part 4: The remaining 10 per cent of land (1 rai or 0.16 ha) is used for building a house, paths and ditches and also for growing household vegetables and raising livestock.
