expert group meeting held in Ouagadougou, Burkina Faso, from 26 to 30 July 1999
The age-old need to make soils more productive and yet, at the same time, more sustainable was the core of debate at an expert group meeting held in Ouagadougou, Burkina Faso, from 26 to 30 July 1999. The problems and prospects of using fertilisers, and of the chemical degradation of soil caused by traditional cultivation, were at the heart of the discussions. Moving beyond the obvious effects of injudicious fertiliser use on the environment, the group examined how to make progress in the search for organic nitrogenous fertilisers, such as waste products, and how to study the efficacy of some organo-minerals as fertilisers, taking into account the environmental effects of the heavy metals in them. Among the recommendations were the need for more training and incentives in fertiliser management, applications of local resources as fertilisers, and studies on new bio-fertiliser materials such as Azolla and water hyacinth. Almost thirty scientists from South Africa, Mauritius, Ghana, Burkina Faso, Senegal, and Nigeria and international institutions attended the meeting, which was funded by the Organisation of African Unity and FAO, and organised in collaboration with the African Soil Science Society.
