Fig. 2. Relationship between volume-weighted molybdate-reactive phosphorus (MRP) in leachate during May through July 2000 and water-extractable soil P from November 2000, uncorrected for the extractant volume to soil extracted ratio, at several depths for the prairie (P) and N-fertilized (f) or unfertilized (nf) and no-tillage (NT) or chisel-plowed (CP) corn agroecosystems. Standard error bars are provided for replicate leachate MRP and water-extractable soil P concentrations.
