Abstract
Applications of (i) 22.5 t ha −1 of pig dung and (ii) 3 t ha −1 of dry rice straw were made on paddy soils in a field experiment that included an annual rotation of barley, early rice and late rice. Representative undisturbed soil cores and soil samples were collected from the experimental field plots. Physical properties, including soil moisture characteristics, were determined for the soil samples. The various physical properties did not differ significantly, indicating a lack of response to the added organic matter. The absence of improvement in the physical properties of the soil was probably due to the action of puddling, which is consistently practised prior to transplanting and the establishment of each rice crop.
