The Secrets of Soil pH Balance

Soil pH is one of the most overlooked factors in crop productivity. When soil becomes too acidic, key nutrients like phosphorus and calcium become locked and unavailable to plant roots — even if they are present in the soil.

In this guide we walk through how to test your field soil, read the results, and apply organic amendments like lime or compost to bring pH back into the optimal 6.0–7.0 range for most crops.
