WebApr 28, 2024 · The runoff P results were expressed as concentrations and losses per unit area (kg P ha −1 ), which were calculated from the P concentrations (mg L −1) and the measured runoff (L). 2.7 Statistical analysis Statistical analyses for the runoff trials were performed using the R environment (R Core Team, 2024 ). WebThe natural phosphate levels of the various soil types are low. Additional fertilization is then necessary. However, too much accumulation of phosphate in the soil, for example on agricultural land, leads to phosphate leaching and runoff to the surface water. This is bad for water quality (e.g. algae growth) and biodiversity.
