A scientist collects runoff and sediment from a soil box under simulated rainfall in the NSERL hydraulics lab.
 Field rainfall simulation experiment, studying the effect of fertilizer placement on phosphorus leaching.
 Small field monitoring site in northeast Indiana, with runoff flow through a drop-box weir. Water samples are collected and stored inside the small building.
 Steel slag being added to a large phosphorus (P) removal structure. Soluble P in tile water flowing through these structures attaches to the slag.
 Screen shot of results from a WEPP model application to a watershed in Minnesota. Red areas indicate high sediment loss (>5 t/ha/yr), while green areas have lower predicted erosion (0-5 t/ha/yr).


**Mission** The mission of the National Soil Erosion Research Laboratory (NSERL) is to develop the knowledge and technology needed by land users to conserve natural resources for future generations.
