Scattered trees in general and scattered waddeessa (Cordia africana Lam.) trees in particular are very common across the agricultural landscapes in Oromia, Ethiopia. A study on this scattered waddeessa trees commonly growing on farmers’ agricultural fields was conducted at Bako in western Oromia, Ethiopia with the objective of assessing their role in modifying the soil properties in the agricultural landscape. Soil samples from surface layers (0–10 cm) were taken at three concentric transects (0.5, 2 and 4 m) around the tree and compared with soil samples from the adjacent open areas (15 m distance from the tree), and then analysed following the standard procedures. Results showed that scattered waddeessa trees significantly modified the overall properties of the soil in the agricultural landscape of Bako area. But soil texture was not affected, indicating that it is more related to parent material than the tree influence. Hence, the soil patches observed under these waddeessa trees can be important local nutrient reserves that may influence the rural agricultural landscape. They also play an important role in generating local household income from the sale of products and conserving biodiversity by providing habitats and resources that are otherwise absent or scarce in agricultural landscape.

“…Similarly, Z. spina-christi was reported to have no negative impact on agricultural crops (Teketay and Eshete 2004). It is rather known to improve soil quality by increasing available phosphorus and total nitrogen and increase yields of associative crops (Verinumbe 1993).…”

The study was undertaken in three districts of Amhara region to assess the extent and purpose of integration of wild indigenous woody perennial fruit bearing species in the agricultural landscapes, appraise their species composition and diversity and identify factors holding back farm integration. Data were gathered through interviews administered to 90 randomly chosen household heads, and fruit trees census in each and every plot of the informants. Species diversity was found to be low and vary by farm, land use type and site. Altogether 17 species were recorded in the agricultural settings. Species retention in the different land use types appears to be governed by species relative importance and compatibility with annual crops, where farm edges recorded a higher ethno-ecological importance score. Nevertheless, as it stands now fruit bearing species are retained primarily for non-fruit utilities. Free availability, land shortage, slope and altitude as well as disgrace feelings are among the major factors holding back farm integration and diversity of indigenous species for fruit production. Should they are additionally exploited for their fruits proper, there is a critical need to raise recognition and awareness at the rural grassroots level and instill knowledge about the food values, and assist in appropriate tree management techniques and inter-cropping regimes as well as accessing markets.

“…En outre, plus la distance de prélèvement du sol a augmenté, plus la quantité de fanes d'arachide nécessaires pour produire une unité de gousse Pour le mil, la hauteur, la longueur totale, la biomasse de la partie aérienne et la biomasse totale ont également été plus élevées sur le sol prélevé à R/2 des troncs. Verinumbe (1993) avait observé, à l'aide d'un essai biologique, que la biomasse aérienne ainsi que la croissance en hauteur de Sorghum vulgare étaient plus importantes sur le substrat collecté sous le couvert que hors du couvert de A. albida et Ziziphus spina christi. Selon l'auteur, les deux espèces avaient amélioré la fertilité du sol sur une distance équivalente à deux fois le rayon du houppier des arbres.…”

Dans les systèmes agroforestiers, les cultures sous le couvert des arbres (SC) bénéficient de plus de nutriments, après décomposition et minéralisation des litières, que celles hors de leur couvert (HC). La fertilité des sols et la productivité du mil et de l'arachide ont été évaluées sur des sols prélevés à différentes distances de Cordyla pinnata, une légumineuse arborée qui forme un parc agroforestier au Sénégal. Les analyses de sols ont montré des valeurs plus élevées pour N total, Ca échangeable et CEC sous le couvert de l'espèce. Pour le mil, la hauteur, les biomasses aérienne et racinaire ont également été plus élevées sur les sols SC. Par conséquent, la biomasse totale du mil a fortement augmenté (+ 90%) sur les sols SC. Pour l'arachide, la longueur totale, les biomasses (tiges, feuilles, gousses, racines) ont été supérieures sur les sols SC. Comme pour le mil, la biomasse totale de l'arachide a augmenté (+ 94%) sur les sols SC par rapport au découvert. La plupart des variables des cultures ont été plus élevées sur les sols SC, probablement à cause de leur meilleur statut nutritif. L'introduction des arbres dans les systèmes de production au Sahel pourrait ainsi constituer une bonne stratégie pour améliorer la fertilité des sols et contribuer au développement d'une agriculture durable.
