Everybody’s results can be different with the same methods. When I was farming I got into peas because nitrogen was not needed and they were supposed to put nitrogen in the soil. I did exactly as I was told by a friend and also a agronomist. On my farm I never got the big yields to turn a profit with the peas. After growing peas I had soil samples done for four years in a row on the pea ground. The nitrogen never showed up. I was farming to try and make a living so it was back to the standard crops here.
