Thank you, Thank you, Thank you! Very helpful, indeed. Now we just have to figure out a way (probably not the 'lab' way...)to measure it in the field, on the fly, so to speak. Hmmm.[wink]
When a farmer sends in a soil sample, how does the lab determine the nitrogen content? Is it possible to measure it on-site? I know next to nothing in this area, so use small words.:)
