Soil suitability and agriculture in Siaya County

Understanding the local soil chemistry is essential for optimizing crop yields and selecting the right inputs in Siaya County. Situated within the Lake Victoria Basin zone, this region features varied soil profiles that directly influence crop suitability. With a recorded average soil pH of 5.33, farming practices must adapt to balance acidity or alkalinity to ensure optimal plant nutrient availability.

The major soil type here ranges across different sub-counties, requiring tailored fertilizer applications.
