Potential Role of Live Fences for Nematode Management on Watersheds in the Senegalese Sudano- Sahelian Area. The influence on the nematode communities of three type of live fences (Zizyphus mauritiana, Bauhinia rufescens and Acacia nilotica) was studied in Sinthiou Kohel, in the sudano-sahelian area of Senegal. Numbers of plant parasitic nematode were greater in the vicinity of the live hedge than in the adjacent fields. The effect was apparent to a depth of 40 cm and 2 to 8 m up and downhill. Fewer plant parasitic nematode were recovered from A. nilotica than from the two other plant species. The increase in size of the community was associated with an increase in species diversity, mainly in the Z. mauritiana rhizosphere. Live hedge supported nematode species that were not present in the adjacent fields. Free living nematodes were more abundant under the live fences, whatever the sampling depth. Live fences influenced these nematodes over almost 5 m downhill against only 2 to 3 m uphill. The importance of the live fences, established in this area to prevent erosion, is discussed in relation to their potential for the management of soil parasites and soil fertility factors, that can be transported in runoff water. |
