Abstract:
A method of determining a difference in the value of a first spatially-variable field characteristic, said method comprising the steps of:a) preparing a field, wherein said field comprises a first and a second crop test area; b) obtaining spatially-referenced field characteristic data for a designated region of said field, wherein said region comprises said first and said second crop test areas; c) designating said spatially-referenced field characteristic data to said first or said second crop test area; d) defining cells in said first and said second crop test areas, wherein said defining comprises designating length units within said first and said second crop test areas; and e) comparing said field characteristic data for a first cell from said first crop test area to an adjacent first cell from said second crop test area to identify a difference in the value of said field characteristic data.
