Long-Term Impacts of Poultry Litter on Soil pH and Phosphorus in No-Till
Common N–based rates for poultry litter (PL) application in the mid-Atlantic region were tested over nine years to track changes in soil profile pH and P concentration.
A common in-house best management practice of modifying PL-P solubility by lowering PL pH did little to prevent P build-up over time and did not reduce plant available P that would limit growth.
