In order to increase crop yields and encourage farmers to apply inorganic fertilizers, fertilizer micro-dosing technology was developed. Fertilizer micro-dosing or “micro-fertilization” consists of the application of a small quantity of mineral fertilizer together with seeds of the target crop in the planting hole at sowing or 2-4 weeks after sowing. The objective of this paper is to review literature concerning crops responses to fertilizer micro-dosing in West Africa. The review also evaluates the benefits and challenges associated with nutrient management under fertilizer micro-dosing and supportive strategies for further improvement in the efficient use of limited nutrient sources of smallholder farmers were suggested. Recent scientific developments on fertilizer micro-dosing revealed that this technology has given promising results in respect of crop yields improvement, fertilizer use efficiency and economic returns. Other studies have, however, indicated that fertilizer micro-dosing increases the risk of soil nutrient imbalances due to low-input. For this reason, we suggest that fertilizer micro-dosing should be used in concert with organic amendments to optimize productivity of smallholder farmers in West Africa. date: 2017-04 date_type: published publication: African Journal of Agricultural Research volume: 12 number: 14 publisher: Academic Journals pagerange: 1169-1176 id_number: 10.5897/AJAR2016.11559 refereed: TRUE issn: 1991-637X official_url: http://doi.org/10.5897/AJAR2016.11559 related_url_url: https://scholar.google.co.in/scholar?hl=en&q=Fertilizer+micro-dosing+in+West+African+low-input+cereals+cropping%3A+Benefits%2C+challenges+and+improvement+strategies&btnG= related_url_type: pub citation: Blessing, O C and Ibrahim, A and Safo, E Y and Yeboah, E and Abaidoo, R C and Logah, V and Monica, U I (2017) Fertilizer micro-dosing in West African low-input cereals cropping: Benefits, challenges and improvement strategies.
