DopplerWerner 122007713This study aimed at understanding current status of soil fertility management and the identification of socio-economic characteristics influencing the decision of households on fertilizer use intensity in maize-based production systems in the northern guinea savanna of Nigeria. A total of one hundred and sixty households involved in maize-based production system (2003/2004) were interviewed using structured questionnaire. Data collected were analyzed using descriptive statistics and binary logit model. Analysis revealed that households combine techniques like application of organic and mineral fertilizer and crop planting pattern in maintaining the fertility of their soils. The ratio of N: P2O5: K2O per hectare from both organic and inorganic sources were 49.5:98.3:56.7 kg in Katsina State and 58.7: 109.4: 53.6 kg in Kaduna State. The estimated logit models revealed that fertilizer use intensity is significantly influenced by previous year`s income, land ownership, engagement in off farm activities and years of experience in maize farming.]]>Adedeji, A.O. and P.
