our contact was a really good guy, and I think quite knowledgeable.

However, their "stuff" just had no power.........and we spent some large dollars with them, according to their district man and the salesman.........so we did not skimp.  (Note that we are restricted in the fertilizer we can use, and theirs ".....was the complete program for our needs".

I've read his book twice, and attended the seminars religiously---------and have gotten more from the discussions on this site.

When we went to litter and then another outfit for trace minerals............our yields went up 40%........at much, much less cost per bu.

I think the old saw "there's no silver bullet" is quite applicable.  ("Back to basics" is another.)

However..........the people were really good guys..............I just couldn't afford the yield hit. 

FWIW.
