Southern Illinois | I am trying to take 3 years of yield maps and re-define my soil sampling areas as I don't want to move to grid sampling yet. Is there a way to combine all the similar crop maps for 3 years or do I just have to print them out? Not real sure how layering them all into one map would help or not. Even though I am not sure of grid maps, would 3 acre grid samples give me better info as far as not being lacking in fertility? | |
