Abstract:
We examined abundance and diversity of rhizobia, arbuscular
mycorrhiza fungi, nematodes, collembolan, termites,
earthworms, ants and beetles in forest, grassland, mixed
cropping, fallow, sugar and tea plantation; encompassing Mabira
forest and adjacent agro-systems. Belowground biodiversity
(BGBD) sub-indicator was computed to predict the general
soil quality (GISQ). Legume and earthworm inoculation for
conservation and agricultural enhancement was also tested.
Biota abundance and genera diversity diminished with land used
change. The GISQ correlated (p<0.0001) with BGBD hence a
feasible indicator. Inoculation either with rhizobia or earthworms
gave profitable soybean and maize grain yields, respectively.
Building capacity for further studies is recommended.
Nous avons examiné l’abondance et la diversité des rhizobiums,
des champignons mycorhizes arbusculaires, des nématodes, des
collemboles, des termites, des vers de terre, des fourmis et des
coléoptères en forêt, en prairies, en cultures mixtes, en jachère,
dans les plantations du sucre et du thé, en englobant la forêt de
Mabira et des agro-systèmes de proximité. Les sous-indicateurs
de la biodiversité souterraine (BGBD) ont été calculés pour
prédire la qualité générale du sol (GISQ). L’inoculation de
légumineuses et de vers de terre pour la conservation et la mise
en valeur agricole a également été testée. L’abondance et la
diversité des genres Biota ont diminué avec le changement des
terres utilisées. GISQ La corrélation (p <0,0001) avec BGBD,
pour cette raison a donné un indicateur possible. L’inoculation,
soit avec des rhizobiums ou avec des vers de terre a donné
rendements rentables de graines de soja et de maïs
respectivement. Le renforcement des capacités pour d’autres
études est recommandé.

Notes:
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme soil science and water management".
