I just ran the NDR model and believe I have some low results: 0.5kg/ha/yr export N and 1.0 kg/ha/yr export P. I was wondering if there is a general range that I can use to place some context around these results? My LULC comprises an area with forest, agriculture, developed land, shrub land, wetlands, and more- it’s quite diverse.
Furthermore, I have two additional questions.
For annual precipitation, is there a unit requirement? Mine is from a U.S. database and is in inches I believe. I am just wondering if this would impact the results.
Lastly, I used values from the nutrient database excel sheet provided via the link in the user guide, do these values need to have the loads corrected for? For agriculture I used actual nutrient application (fertilizer) rates for my region but for all other LULC categories I used an average of values from the excel sheet for my koppen climate, and am not sure if I need to apply the correction or not. Any feedback is appreciated! Thank you.
