The Impact of Soluble Fertilizer Inputs on Agroecosystems   The notion that fertilizers must be water soluble for passive uptake by plant roots is inconsistent with the processes of nature. There is actually very little, if any, dissolved plant nutrients …

pH:CEC Ratio

A new approach to predicting agronomic potential Soil pH adjustments and plant nutrient ratios based on cation exchange capacity have been used successfully for many decades to support more sustainable approaches to crop production. Recently, the mathematical relationship of soil …
