1/4 lb of what over what area? Are you using that 13-0-44 product, or something else? I guess I'm a bit particular when talking about product rates. Is it 0.25# N/A? 1/4 lb/A of 13-0-44 is only 0.03# N/A, which isn't much at all. I guess I like the straight apples-to-apples comparisons, instead of talking about different amounts of different products.

Is the Mn needed? Do you have deficient soil tests or tissue tests? I also hear a lot of guys talk about micros, but I'm not convinced they need them. If you don't have a micronutrient deficiency, why apply them? If you have availability problems b/c of salts or pH, why not correct the problem -- it would be cheaper.
