Crop Production Tool - Yield values are very small
I am working with the Crop Production tool and I'd like a little help understanding what seems to me to be a strange output.
I have a study area that is about 700km by 400km. Within this study area there are multiple patches where soy is being grown for which I'm interested in obtaining the yield values. The first file that I've attached (entitled Soy1_Other0.JPG) is how I've set up the raster for the Crop Management Scenario Map. The pixels are about 10km by 10km in size and the pixels with a value of 1 represent the areas that I'm interested in where soy is being grown. Pixels with a value of 0 represent all other land cover types. However, when I run the tool with this as my Crop Management Scenario Map, I get extremely small yield values (ie, approximately 0.000000001 for most cells).
On the other hand, when I run the tool with the entire study area (700km by 400km) set to 1 (in other words, setting the whole area to 1 for my Crop Management Scenario Map) as I show in the second file that I've attached, I get more reasonable yield values.
Is there any reason why I'm getting such small yield values when I limit the pixels that are producing soy within my Crop Management Scenario Map?
