Abstract:

Taking part to the World Bank Data4SoilHealth Challenge 2025 for Kenya, Yara East Africa, a subsidiary of Yara International, has shared a polygonal dataset that provides insights on several soil parameters form 2023 in Kenya.
Yara International is a leading global fertilizers and crop nutrition company. With a focus on promoting balanced and efficient fertilization practices, it helps farmers optimize their crop yields while minimizing the environmental impact. Through various initiatives and partnerships, the company seeks to equip farmers with the knowledge and skills necessary to make informed decisions about fertilizer application, crop management, and sustainable farming practices. By empowering farmers with these tools, Yara East Africa aims to contribute to the development of a strong and resilient agricultural sector in Kenya.

The data is organized using the H3 spatial indexing library, providing uniform hexagonal polygons with a spatial resolution of 0.015 km2 (1.5 hectares). This structure ensures efficient spatial analysis and integration with geospatial tools, making the dataset highly suitable for large-scale agricultural and environmental studies.
