| We only ran it one time on our ground. Helena charges like $12 an acre to run it and soil samples. After that charge $6 an acre to soil test. We soil sample different parts of our ground every 3 yrs. We only soil sample fields going onto alfalfa by zones from the veris. Mainly to check PH. We use manure and as of now do not need to variable rate it. Most P&K are not that far off. We will zone sample fields that are continuous corn every 6 yrs. We just composite sample fields that are not going to alfalfa. Unless they are big fields we will pull different sections. It cost to much to do zone sampling every year. They are now using as skid that can be pulled by a side by side.And they have taken yield maps and over laid them on soil maps to compare
