Paul: You bring up a good point. I'm, here in New Orleans at the Commodity Classic and what you mentioned came up in a presentation by Marion Calmer on Thursday. It's being followed up on later this morning by Dr Fred Below, Univ of Il, and that is vertical stratification of soil nutrients, most notably P & K. Calmer has been into no-til and had noticed that his corn wasn't getting the P & K it should have been getting in accordance to what he was applying. This was confirmed with tissue samples. So, he designed a soil test probe that can accurately measure soil samples vertically by the inch. He found he had high levels of P & K in the top few inches of soil but low levels down deeper where the plants need it. The plant roots need to find P & K because P & K don't move around much. So, he broke out his old moldboard plow and plowed a 5 acre test plot, down to about 8 to 9 inches deep. Through subsequent vertical soil testing he found that he had moved the surface P & K down somewhat which did produce a better corn crop that year. Follow-up testing is to be carried out in the near future. I hope to find out a little more about this later this morning.
