That might be an interesting project/ experiment. I thought about that in response to Sand85's thread above. Sampling in mid-season, when crops are actively growing, when soil moisture is getting depleted, might show decreased nutrient availability. But does that mean you need nutrients? or does it mean that you need more soil moisture to increase nutrient availability? ??? In the end, monthly soil sampling just might drive you crazy. It might be an interesting experiment though. | 
How often to soil test?
