    This is a 2 year study from the university of Colorado on runoff monitoring of compost applied to turf.


    Compost can improve soil properties when incorporated into soil; however, little information is available regarding impacts of compost topdressing. Objectives of this study were to evaluate the effects that topdressing composted dairy manure onto Kentucky bluegrass (Poa pratensis L.) has on: (i) soil physical properties, (ii) soil chemical properties, (iii) soil nitrate (NO3┬ľN) and P concentrations below the rootzone, (iv) total runoff and sediment losses, and (v) N and P concentrations in runoff. Plots were topdressed with compost at 0, 33, 66, and 99 m3 ha21. Saturated hydraulic conductivity, bulk density, water retention, and soil nutrient levels were measured.

    Didn't I just post this? Or perhaps I just downloaded it. Too many studies, not enough time.
