Vegetative barriers significantly improved the soil
fertility over the control plots (Table 3), which is the
reflection of soil, nutrients and water conservation
effects of the vegetative barriers. The highest organic
C build-up (0.49%) was recorded from the sambuta
treated plots which was significantly higher than the
vetiver, lemongrass and control plots. Available K
status was also the highest under sambuta treated
plots (378.13 kg ha-1
) which was 26.9, 39.7 and
62.9% higher than the vetiver, lemongrass and
control plots, respectively
