Change tillage practices
A controlled, replicated experiment in 1998-2001 on a clay soil in Sweden (Djodjic et al. 2002) found that higher average phosphorus levels were found in soil under the no-tillage treatment (1.86 kg/ha) compared to conventional tillage (1.59 kg/ha) and conventional tillage plus incorporation of phosphorus fertilizer (1.25 kg/ha). There was no major effect of tillage compared with no-tillage treatments on phosphorus filtration through the soil. Large columns of soil (monoliths) were collected and exposed to three treatments: conventional tillage (five replicates), no-tillage (five replicates), and phosphorus fertilizer incorporation (three replicates). All liquid draining from the monoliths was collected, and the concentrations of soil phosphorus and dissolved phosphorus were measured.
