I was reading your note regarding soil pH and peanut. The target pH is 5.8. The recommendation to raise the whole field average to 6.2 to attempt to have a minimum of 5.8 is certainly feasible, given your statement that problems with higher pH are not as severe as lower pH. There is another option and that is to use variable rate lime application. This will require either grid or targeted soil sampling to detect the areas of concern, but variable rate lime could achieve the desired result without elevating pH values above the target level. I know there are some suppliers across the peanut belt that have variable rate lime capability. Not sure how many, but that is an option to consider.
Yes, that would be a possibility. I know some growers are using variable rate applications. Lots of benefits for that approach.
