Phosphorus Release Dynamics From Cover Crop Residues: A Comparison Between Single Species and Mixtures

Soil Use and Management, Volume 41, Issue 2, April‐June 2025.
ABSTRACT Cover crops (CCs) can help reduce soil erosion and promote nutrient cycling, and certain species are efficient phosphorus (P) miners. Upon incorporation into the soil, CCs biomass undergoes microbial mineralisation, releasing bioavailable P, potentially benefiting subsequent crops. However, the effects of the incorporation of single CC species
