Yields of groundnuts in West Africa are low because the soils are often calcium-deficient and small-scale farmers cannot afford to buy the supplements. However a simple remedy is to add wood ash to the soil. Groundnuts grown when there is a shortage of calcium produce very small seeds, and in cases of severe deficiency there may not be a crop. To rectify the shortage of calcium, it has been recommended that farmers add 400 kg per hectare of gypsum. Small-scale farmers cannot afford to buy that amount of fertilizer, so researchers at the Sahelian Centre of the International Crops Research Institute for the Semi-Arid Tropics in Niger have been looking for a cheap alternative. They have found that wood ash is a very effective substitute for gypsum and its use increases yield and quality. Collected and stored throughout the year, wood ash can be applied to the groundnut crop at flowering. Shortage of calcium restricts growers to small-seeded varieties which have a low market value but by increasing calcium levels with wood ash, farmers can choose the large-seeded varieties which have a higher market value.
