I am using ArcGIS Pro 2.4.0.

I am making a fertilizer application map that changes the rates, based on the location of the field. The overall goal of the operation is to create a grid of squares, each with a grid containing a result of the Kriging interpolation.

I have a point file with nitrogen nutrient levels, the result of a soil-sampling operation:

The attribute table (with a row with for each point) that comes with it looks like this:

I want to know the specific level of nitrogen (NO3) in the field, so I used Kriging to interpolate it:

Now I have to convert from a floating-point raster to an interval raster. To do this, I first converted the floating-point raster (produced by Kriging) to an integer raster using the "Int" tool. Then, I used the "Raster to Polygon" tool to create my grid map. The grid produced is below:

I'm trying to get each of the grids to represent one of the Kriged nitrogen levels, but when I do a joins-and-relates action, I get a table with a bunch of unknown values.

I need the grids to reflect the values of the Kriging map that was generated earlier. How can I do that? Am I missing a joins-and-relates somewhere?
