My corn sunflowers and grain sorghum will need topdressing with urea once it dries out enough to get over it. How many units of urea should I put out CNC?

If you're just wanting to provide biomass, then why pay to plant anything?

How often do you fertilize and how much do you put out? Have you done your soil test recently?

I�ve been adding 50 lbs/ac of 33-0-0 about every 3 months. I added a bag at fall planting last year�..one around Christmas��.one during March when the rye started actively growing�..and now I�ll likely add one more around mid June when my summer crop gets up a little better. My soil is really sandy with a low CEC so its better to throw out smaller amounts more often anyways.

On the other nutrients I just go by the soil test. Yes I just got my soil tested a couple weeks ago. Not really a whole lot of change from last fall. My Ca was still rising slightly from last fall's test. It was up another 50 lbs/ac. Lime added 15 months ago. The K had fallen off from 210 lbs to 155 lbs but the test still didn�t call for adding any. The P was slightly low so I went ahead and mixed in 50 lbs of 0-46-0 with the seed I threw out. The crazy thing was that even though my Ca was still rising�.my pH had actually dropped slightly. Still in the mid 5�s. The test was calling for adding another ton of lime. I�ll may mow at some point this summer and double crop the biomass. If I do I may throw out a little palletized lime mixed with 50 lbs of 0-0-60��positively + charged ions. My test will most likely call for K later this fall anyways.

Dang your ph is low. Why not just go ahead and put a ton of lime to the acre.

Dang, your ph is pretty low.

If you dig down in my soil to around 8-12 inches the pH is 5.0....That soil runs down to a depth of 50 inches before it hits a clay layer. Even then its a sandy type clay. It's the pH in my upper horizon of OM that I'm really effecting. That black layer that you see in my soil profile pics.

Why did you dig down 8-10" to send off for a soil test?

I think this sunn hemp is gonna be the real deal. I like what I see so far. I put down 250 lbs of 17-17-17 per acre and 15lbs of seed.

To compare the pH and nutrient levels in my upper horizon where I�ve built up the OM versus the �subsoil� with no OM���

CNC, I don't think anybody is saying your way "Won't" work. I just think they are saying don't cram it down thier throat, that this is the best way. Yoh have took some simple ??? And made them complicated. You are try to argue with someone, who makes his sole living doing this. He's not saying your way is wrong. Your just trying to say your way is better. Imo. That's hiw I'm reading this. And yiur taking some comments like a puss, and blowing them out of proportion. Just the way It seems to me.
