A method for soil data interpolation includes collecting first and second agricultural field point data values corresponding to a variable grid and generating interpolated point data values by analyzing the first and second agricultural field point data values. A computing system includes a processor and a memory storing instructions that, when executed by the processor, cause the computing system to collect first and second agricultural field point data values corresponding to a variable grid and generate interpolated point data values by analyzing the first and second agricultural field point data values. A non-transitory computer readable medium includes program instructions that when executed, cause a computer to collect first and second agricultural field point data values corresponding to a variable grid and generate interpolated point data values by analyzing the first and second agricultural field point data values.
