This was our first year of in furrow with 10-34-0, we put down 5 gal with Schafferts and their Y splitter, we also put down 5 gal of 32% behind the closing wheels with a dribble tube. Both worked well in corn but we found that in our clay were going to have to run something out when doing beans or it will plug the nozzles on the Schafferts, whether that is straight water or some kind of bean starter remains to be seen. I used 12v pumps and Ag Spray controllers to drive them, I carry 300 gal of each in saddle tanks on the tractor. As far as the starter slowing me down planting, its not a big deal IMO, I can fill both tanks in under 10 minutes using a 2" banjo pump for each product. When I have the tender in corn, I can load fertilizer, then turn around and load 12 boxes of corn in under 20 minutes without hurrying.  

Our other planter uses a 2x2 system, we have the Sunco Nutrimates, they worked well and did exactly what they are supposed to do. My only complaint was that I thought they used too much downpressure and made the row unit ride a little rougher. If we had some mellower soils I might have put a set on the new planter, I dont hate them, just didnt like them enough to buy another set of them. Plus I wanted floating row cleaners, which they make but didnt want to lay out that kind of cash for the Nutrifloaters.  I think next season this planter will be converted to the in furrow/dribble tube setup as well. We were putting down all of our P needs with this system in a 10-34-0 and 32% mix, usually at 15gal/acre

We ran both this year and cant tell a difference between them, though neither are techically side by side with the same hybrid, plus we had as close to a perfect season as well ever have as far as weather. I dont think a guy couldve gone wrong this year. I will say that I think the in furrow stuff gets going a little quicker than the 2x2, just because the fertilizer is right there when it needs it instead of having to grow to reach it.  

Going forward we will have to spread some 11-52-0 to keep our P levels up, but unless the price gets way out of wack, we should still be cheaper this way than using liquid P.
