An analysis of conventional on-farm development projects pointed out the lack of a systematic procedure applicable to implementation of the works. A new procedure has been developed by clarifying the requirements of each stage of the work from the field investigation to the construction and supervision stage. This procedure was characterized by: (1) adopting a grid survey map, (2) specifying the disposal of the soils, (3) estimating the earthmoving volume with the ponderable balancing method, (4) establishing criteria for quality control and (5) determining the scope of work of the supervisor.
For examining adaptability, the procedure was applied to an on-farm devel opment project in Tanzania, which had the purpose of constructing 3, 800 paddy fields with a dimension of 100×30m.
On the basis of this application it was concluded that:
(1) a grid survey map was sufficient for designing on-farm works;
(2) rational disposal of the soil had a good effect on the growth of paddy;
(3) efficient design and the ponderable balancing method could exactly cal culate the earth works;
(4) established criteria for quality control were justified by the smooth exe cution of the works and the easy farm operation; and
(5) the supervisor with conferred power could control the progress and the cost of the words.
