The contents of Noumuchou can be divided into six sections: 1) conservation of agricultural land, 2) methods of cultivation, 3) cooperative community cultivation, 4) laying aside produce for times of emergency, 5) growing useful plants and 6) the duties of agriculture-related officials. From these sections it is possible to extract regional characteristics particular to Okinawa. Several points are detailed below. The first concerns technical methods of conserving soil fertility. There are two terms found in the original Japanese (souroubun) text that relate to this: 'mizokamae [literally 'ditch arrangement/position']' and 'ifukaeshi.' Deep ditches ('mizo') are dug at the edges of fields to accumulate rain water that can then flow back into the agricultural land to keep it fertile. This process is called 'ifukaeshi.' Because this work is extremely important in keeping soil fertility high, conserving agricultural land and increasing productivity, Noumuchou provides strict guidance to agriculture-related officials on this matter. The second relates to hill forest and agricultural area land-use classification. Because of the importance of forests in terms of obtaining cattle feed and firewood any decrease in the extent of forest should it be cut down in order to expand the area of arable land is a worrying situation. With this in mind, boundaries between cultivated land and forest should be clearly demarcated by digging ditches or by planting trees. So as to avoid any disputes with regard to the boundaries of agricultural land trees should be planted, stones placed or ditches dug. The third point concerns the planting of adan (Pandanus odoratissimus) as an agricultural land shelter belt measure. Adan is commonly planted near to agricultural land in coastal areas to prevent damage to agricultural land from sea water. The planting of adan along river banks to prevent soil collapse is also encouraged. A fourth point concerns the use of water from paddy fields. Unlike mainl
