Runoff and leachate losses of phosphorus in a sandy spodosol amended with biosolids
(AMER SOC AGRONOMY, 2008)
Florida Spodosols axe sandy, inherently low in Fe- and Al-based minerals, and sorb phosphorus (P) poorly. We evaluated runoff and leachate P losses from a typical Florida Spodosol amended with biosolids and triple ...
