While processing drone-based NDVI images that were not properly stiched and had
missing segments, I realised that if grid overlayed over NDVI raster image did
not have any index entriy, the plugin was crashing. I have implemented a
solution by removing those specific grids (features) from processed layers. This
is very important to be aware of, and because of that I have added a popup
message warning a about each feature not included. There was minor issue in
calculations of the nitrogen (yield) "min" recommendations, and that was fixed
as well. In regard to general options, this version is same as previous and the
same Guide to User available at hompage should be used.
