On sites field monitoring of soil strength to study the continuous effects of highly intensive rice production system at rice estate of FELCRA Seberang Perak, showed the trends of the soil strength was greatly depend on the standing water depth in the rice field. The trend of rice yield and soil strength did not show much changes across the different planting seasons from 1996 to 1998. In another study at Bertam, the effects of different tillage systems (which maintains, breaks, and creates hardpan practices) showed the rice yield of the standard tillage followed with puddling practices was higher compared with other tillage treatments. The deep tillage increased the availability of soil P content during the initial stage of crop growth while the Ca availability was most of the soil nutrient, especially the content of Cu, K, Mg and Zn. However, there was no obvious trend to show the changes in total nutrients uptake by the shoots and grains ana lyzed.
