Major types of Existing Soil Information
• Soil profile Physico-chemical database
• Soil classification maps (global, regional, country levels)
• Soil fertility data (Wet chemistry and Spectral)

Recent Efforts and Actors • Individual country initiatives such as SA, Ethiopia,
Nigeria, Tanzania, Ghana, etc.
• International efforts to produce Africa soil maps and data (FAO, ISRIC, etc.).
• Africa–focused initiative in soil resource mapping by AfSIS (not suited for fertilizer recommendation).
• Stakeholder-assisted efforts such as what is being attempted by OCP in several African countries.
• Efforts being made by private soil testing companies (CNLS, Soil Cares, etc).

Africa Soil Profiles Database(http://africasoils.net ; http://www.isric.org)
@18,532 unique Soil profile records (93% are geo-referenced) for 40 countries.
Standardized and cleaned.
Soil analytical data are available for 15,564 profiles (of which 91% are geo-referenced).
Some individual countries also own fragmented soil profile information for targeted locations.

CONCLUSION• Africa does not have a consolidated and up-to-date
regional soil information database; this is also a problem at country level.
• If countries have such information, it is fragmented and not holistic, thus making it difficult to feed into African soil database or even use as legacy data.
• While frequent efforts are there to generate soil information by stakeholders, they are not coordinated to enhance meaningful output (such as guiding the fertilizer advisory package at national level) and cost effectiveness.
• Lack of apex institutions at both regional and country levels greatly contributes to the problem.
![Page 31: African Soil Information System](https://reader036.vdocument.in/reader036/viewer/2022070518/58e4e4af1a28ab87378b4b6d/html5/thumbnails/31.jpg)
• The policy body lacks up-to-date knowledge or information about soil being a non-renewable resource that is facing danger of extinction (E,g. Ethiopia wouldn’t have thought about launching EthioSIS without the establishment of the Ethiopian Agricultural transformation Agency, ATA).
• Africa cannot afford to ignore its soils since 95% of the food we eat
grows on soils and we need to leave healthy soil for the future
generation.
• Professionals have the responsibility to continuously knock on the door of the policy body to get heard.
‘’The Soil should no more be a hidden and unattended resource’’
