Central Missouri | All I know is that I have looked at several thousands of acres of soil samples from multiple states. The fields that have a balanced Base Saturation normally outperform those that don't (at least 80% of the time). In the 20% of the time that someone has an out of balance field that yields well, there is an outlying factor that helps the farmer (excellent management, row placement fertilizer, tillage, etc). If your views are on the side that only wacky people cite the Base Saturation philosophy remember this: when you send soil samples into an independent or university lab and they recommend to add lime, they are trying adjust pH, which also adjust the base saturation in a positive manor. Ideal Base Saturation is : K 2-4%, Mg 10-14%, Ca 65-80%, H <10, Sodium <1. In sand or low CEC increase the Mg and reduce Ca. In Clay, reduce Mg and increase Ca. If you look at enough diverse samples it shows through 80% of the time, at least. | |
