摘要：
We assessed impact of 5 years continuous application of traditional tillage practices (no-till (NT), shallow tillage (ST) and ridging tillage (RT)) applied by smallholder farmers in central Tanzania. Soil samples were collected at two different soil depths to verify farmer' perceptions. At 0-15cm, ANOVA showed no significant difference (p0.05) for tested parameters except total N which was significantly different and rich in NT. Whereas no significant difference were observed for chemical properties analysed at 15-30cm, percentage clay, silt and sand content were significantly different (p0.05) over tillage practices with NT having more silt and clay.
