Abstract:
The Wyss Academy Naibunga Soil Parameters dataset, contributed by the Wyss Academy for Nature at the University of Bern, was donated as part of the World Bank Data4SoilHealth Challenge 2025 for Kenya. Developed through a previous partnership with the Kenya Agricultural and Livestock Research Organization (KALRO), this dataset consists of 48 georeferenced soil sample points from the Naibunga Conservancy. It includes key soil health indicators such as pH, Total Nitrogen, Total Organic Carbon, Phosphorus, Potassium, Calcium, Magnesium, Manganese, Copper, Iron, Zinc, and Sodium. Last year, KALRO conducted an extensive soil characteristics study for the Wyss Academy in the Naibunga area, where semi-circular bunds were dug. More info

Soil parameters overview
| Original Soil Parameter | Unit of measurement | Description | Analytical method |
|---|---|---|---|
| Soil pH | - | The measure of the acidity or alkalinity of the soil, expressed as pH value. | - |
| Total Nitrogen | % | The total nitrogen content in the soil, expressed as a percentage. | - |
| Total Org. Carbon | % | The percentage of organic carbon present in the soil, which is crucial for soil fertility and carbon sequestration. | - |
| Phosphorus (Mehlich) | ppm | The concentration of phosphorus in the soil, measured in parts per million (ppm), using the Mehlich extraction method. | Mehlich |
| Phosphorus (Olsen) | ppm | The concentration of phosphorus in the soil, measured in parts per million (ppm), using the Olsen extraction method. | Olsen |
| Potassium_exchangeable | meq% | The concentration of exchangeable potassium in the soil, expressed in milliequivalents per 100 grams (meq%). | - |
| Calcium_exchangeable | meq% | The concentration of exchangeable calcium in the soil, expressed in milliequivalents per 100 grams (meq%). | - |
| Magnesium_exchangeable | meq% | The concentration of exchangeable magnesium in the soil, expressed in milliequivalents per 100 grams (meq%). | - |
| Manganese_exchangeable | meq% | The concentration of manganese in the soil, expressed in milliequivalents per 100 grams (meq%). | - |
| Copper | ppm | The concentration of copper in the soil, measured in parts per million (ppm). | - |
| Iron | ppm | The concentration of iron in the soil, measured in parts per million (ppm). | - |
| Zinc | ppm | The concentration of zinc in the soil, measured in parts per million (ppm). | - |
| Sodium | meq% | The concentration of exchangeable sodium in the soil, expressed in milliequivalents per 100 grams (meq%). | - |
| Electr. Conductivity | mS/cm | The ability of the soil to conduct electrical current, measured in millisiemens per centimeter (mS/cm), which is used as an indicator of soil salinity. | - |
