Liquid fert for trees

We will be adding a liquid fert to our services this year and I was wondering what %'s you guys are using and where do you get your fert from. I am familiar with how fert programs work because that was big business where I used to work. However I was never totally sold on they way they ran their program, not to mention that we cant buy the same product from the same supplier because of the small quantity that we will be ordering.

Ideally we want something with very low nitrogen and zero phosphorus. But if someone has a specific product that they really believe in, we would consider changing our "wish list"
 
I don't think that there is a simple answer to your question. Probably why no one has responded! We use a combo of myco and kelp for soil treatments although i'm not convinced that a balanced fert for trees whose soil we can't add organic matter to isn't the best way to go.

Soils are just too complicated to have a broad stroke approach to treating them even though the average tree owner can't afford testing and tailored treatments that yield best results.

I'm curious as to what your past employer did.
 
Yeah I know there is no simple, cookie cutter answer but I was hoping just to see what others are doing. I think I know what I want, which is pretty low N, almost zero P and more K, plus some biotics. Off the top of my head I was thinking something like 3-0-20 or something like that. The place we used to work just bought something off the shelf and applied it at whatever amount they felt like. There was no methodology what so ever. I had to sell ferts for them and I never did real well because I didnt believe in it. If I am going to start doing ferts again, I want to have a product and methodology that I really believe in.
