Understanding P Build-Up at the Surface and Depletion Below
Why do some crops struggle to access phosphorus even when soil-test levels appear adequate? Technical Agronomist Taylor Strehl shares how phosphorus stratification develops in modern reduced-tillage and no-till systems, creating uneven nutrient distribution throughout the soil profile. Learn why phosphorus placement, fixation, and accessibility impact crop nutrition, how standard soil tests can miss subsurface depletion, and how RhizoSorb® technology helps improve phosphorus availability by expanding the zone of plant-accessible phosphorus.
