Organization or Author:

OCP Kenya Limited

Abstract:

Taking part in the World Bank Data4SoilHealth Challenge 2025 for Kenya, OCP Kenya has contributed donating soil data points collected using Mid-Infrared (MIR) spectroscopy technology. The data, coming from two distinct labs, is divided in two clusters.
5,107 data points has been ingested into SoilHive for the Cluster 1, coming from the OCP School Lab.
OCP is a global leader in the phosphate and fertilizer industry, committed to supporting sustainable agriculture through science-driven innovations. Operating in Kenya through OCP Kenya, the company partners with farmers, institutions, and local stakeholders to improve soil health and agricultural productivity.
