The software indicates that load_type_x (load_type_p, in my case) must have a numerical input in the biophysical table, however, the user guide suggests that the options should be inputted as either ‘application-rate’ or ‘measured-runoff’. I was wondering if someone could direct me to the key for the numerical inputs that correspond with the different load_type_x options. Thank you!
Welcome to the forum @ceileigh!
I think you’re talking about two separate biophysical table fields.
These two inputs are numeric values of nutrient loading (the following description is from the User Guide Data Needs section):
These two inputs are not numeric, you assign a string value to them, either “application-rate” or “measured-runoff”:
- load_type_p (option, conditionally required): Whether the nutrient load in column load_p should be treated as nutrient application rate or measured contaminant runoff. ‘application-rate’ | ‘measured-runoff’
- load_type_n (option, conditionally required): Whether the nutrient load in column load_n should be treated as nutrient application rate or measured contaminant runoff. ‘application-rate’ | ‘measured-runoff’
So each land use class will have a “load_type_x” string value for the type of loading with associated “load_x” numeric value for the quantity of loading. If this is confusing, we should update the User Guide to be more clear.
We also recommend looking at the sample data that’s provided with each model, which will help illustrate what the inputs should look like.

A post was split to a new topic: NDR: Which loading type is appropriate?
Thank you for your reply. Please allow me to clarify my question. When I input ‘application-rate’ it indicates that the load_type_p column needs a numeric input. It will only run if I assign a integer to the column. How should I proceed? Thank you.
load_type_p and load_type_n are text string values, which can be either ‘application-rate’ or ‘measured-runoff’.
If you look at the sample data for NDR you’ll find an example biophysical table with these values:
I will try to make this more clear in the User Guide.

Hi Stacie, thank you so much. This is the error message i receive: ValueError: Value(s) in the “load_type_p” column could not be interpreted as numbers. Original error: could not convert string to float: ‘measured-runoff’
This is what my load_type_p columns look like. It seems like I am using the same format as the sample tables. Do you know how I should proceed?
Well that’s very strange, it does look correct from that screenshot. Can you post the actual CSV table so we can look at the content and format?

Stacie, I was running version 3.15.1. I have now downloaded 3.16.1 and the model is running no problem. Apologies for the confusion.
Glad that it’s running now, thanks for letting us know @ceileigh.
