Soil Fertility and Crop Yield Variability under Major Soil and Water Conservation Technologies in the Usambara Mountains, Tanzania

Abstract: Indigenous soil and water conservation (SWC) technologies such as miraba (rectangular grass strip bounds that do not necessarily follow contours) and micro ridges have been used widely in the Usambara Mountains, Tanzania. However, their strengths and limitations to crop productivity have not been investigated. This study aimed to determine soil fertility and crop yield variability under

“…Exchangeable potassium is significantly at (p < 0.01) and negatively (r = -0.431) correlated with bulk density. The results of this study is consistent with the finding of Mwango et al (2015) who reported that, a significant correlation between phosphorus and soil pH was observed.…”

“…However, negatively correlated with bulk density (r = -0.201) and (r = -0.304) sand and the correlation is not significant in both case at (p < 0.01 and 0.05. The result is in line with that of Mwango et al (2015) who reported that total nitrogen was significantly correlated with OC and phosphorus (p<.001).…”
