Challenges of formulation and quality of biofertilizers for successful inoculation

The interest in biofertilizers is increasing and so is the potential for their use in sustainable agriculture. However, many of the products that are currently available worldwide are often of very poor quality, resulting in the loss of confidence from farmers. The formulation of an inoculant is a crucial multistep process that should result in one or several strains of microorganisms included in a suitable carrier, providing a safe environment to protect them from the often harsh conditions during storage and ensuring survival and establishment after introduction into soils. One of the key issues in formulation development and production is the quality control of the products, at each stage of the process. This review presents the different components and the major steps involved in the formulation of good quality biofertilizers, including the techniques used to assess the quality of the products following production. The quality of currently available inoculants is also reviewed, emphasizing the need for better quality control systems worldwide. (Résumé d'auteur

Use and cultural significance of Raphia palms

The genus Raphia (Palmae / Arecaceae) contains 22 species and represents a major multiuse resource across tropical Africa and Madagascar. Raphia species provide goods that range from food to construction material and medicine. Its species play a vital cultural role in African societies. Despite its importance, the taxonomy, ecology, and ethnobotany of this genus remain poorly understood. Here, we review the multiplicity of uses, products and cultural importance of Raphia species across its distribution. We provide a near exhaustive list of all products derived from Raphia species, classified by species and major use categories. We record nearly 100 different uses, traded and commercialized at local, regional, and national levels. Most species have several uses. Raphia wine is the most important product, followed by grubs and fiber extraction. Our review improves our understanding of the uses and cultural importance of Raphia species. If Raphia resources are managed responsibly, they will contribute to alleviate poverty, fight against hunger and conserve tropical biodiversity, especially in Africa
