Abstract

Examples of raised-field or island-bed cultivation systems are widely distributed in the Pacific and American tropics. Two types exist. The first is where the fields are well above the water table and are planted with upland crops which benefit from the transfer of sediments and water from the ditches to the cropping area. The flooded-ditch environment is suitable for algal N-fixation and this is vital where soil organic matter and nitrogen levels are low. The second type is the wetland fields used particularly for taro where the soils are too acid to allow algal N-fixation and nitrogen is not limiting. Here the contribution to productivity is through mobilization of available P in the waterlogged anaerobic soils lying below the water table. -R.P.C.Morgan
