Abstract:
Variability of soil carbon in 5 floodplain soils at landscape scales were studied. Transect technique was used in soil sampling at 0, 25, 50, 75 and 100 m sampling points. Results showed that some measured soil properties varied among floodplain soils although all locations belong to the rainforest agro-ecology. The Oa horizons accounted for the highest variability in thickness (CV = 26%) in some locations. There was significant variation in total soil carbon in 60% of the floodplain soils. It is concluded that intensive soil sampling from landscape delineations will provide more accurate and reliable representation of soil carbon for scaling at regional levels.
