NW Iowa | Just looking at different soil test labs to start soil sampling our farm more consistently. Has anyone used a lab that uses the Morgan extract method? Morgan extract claims to be a "weak acid" extract compared to other "strong acid" extract methods. They say the weak acid is more comparable to exudates that roots give off. Just wondering if anyone has experience with this method and what your opinion is on it compared to others.
This would be for nw Iowa high cec soils
TIA | |
