Mapping spatial variability of soil nutrient deficiencies in smallholder villages – a prerequisite for improved crop production in Africa

Abstract

Various approaches to derive decision support for site-specific soil fertility management were assessed in a smallholder farming system, a village in western Kenya. The results indicate that at least a small number of soil analyses from the village is important. A collaborative approach among farmers within an area or village can facilitate detailed and cost-effective soil properties mapping, where parts of samples are analyzed in the laboratory, and most samples are scanned by a combination of sensors. Maps from continental geodatabases were less useful.
