The Nigerian Soil Survey and Soil Fertility Management Project which was carried out from January to April 2022 in Four Pilot States: Edo, Gombe, Jigawa and Oyo was centered on developing and implementing a Nigerian systematic approach for Soil Survey & Soil Fertility Management in improving soil productivity on croplands across Nigeria.

The progress report of NSS&SFMP was presented to the Director/ALCCMS (Chairman), Director/SS&LE and staff of the department of Agricultural Land and Climate Change Management Services (ALCCMS) by the Coordinating Consultants at a meeting in the Honourable Minister’s Conference Room, FMARD, Abuja.

It was mentioned that the ever-increasing human population in Nigeria demands corresponding increase in food production, with sustainable soil management and low fertility being critical challenges.  In addressing soil management problems, significant changes are needed through focused research on sustainable intensification, and multi-stakeholder partnership. The SS&SFMP has brought key stakeholders to take practical actions that will move the agricultural sector forward by leveraging on digital innovative systems, for enhanced productivity.

The SS&SFMP was carried out using the Africa Soil Information Services (AFSIS) sampling protocols while soil data collection was done using the open data kit (ODK) KOBOCOLLECT Application.


Soil samples were collected in Surface, Subsurface and Profile sample across the four pilot states as follows;

GOMBE 79 196 253 98 351
JIGAWA 132 517 517 298 815
EDO 123 0 355 307 662
OYO 211 0 906 319 1225

The soil samples collected was analyzed in the four national soil testing laboratories of the Federal Ministry of Agricultural and rural Development, located in Abuja. Kaduna, Imo and Oyo using the Mid-Infrared spectra (Nigeria Bruker OPUS Files Conversion). The analysed data was sent to specialists for interpretation and fertilizer recommendations for the states.
