Effects of intensified agricultural practices on upland rice productivity in northern Thailand
Results are presented of study conducted during 2000 in Chiang Mai Province, Thailand to examine the effects of intensified agricultural practices on soil fertility, weed infestation and upland rice yield. Agricultural intensification appears to offer an alternative to slash-and-burn systems in the hilly region of Thailand. While terracing and increased cropping intensity may reduce soil fertility, a higher rice yield can be achieved through agronomic practices, by combining tillage with appropriate fertilizer management and crop rotation.
