|Hello, I am wondering if any of you have amended your dirt before landscaping a new construction lot? I'm talking about adding phosphorus, maybe chelated iron, microhizal fungi, ammonium sulphate, etc. I had a soil test done and I'm high in nitrogen and potassium but very low on phosphorus and my pH is 7.7. Our lot right now is just plain fill dirt brought in by the builder for grading. We are going to be finishing our landscaping this summer. I'm planning on doing about 50% kentucky bluegrass (lawn), and the rest a small fruit orchard, raspberries, vegetable garden, various trees and perennials. I'm definity adding several tons of compost, so I know that will help but I'm more wondering about the other stuff. I've heard contradicting answers and wondering if any of you have an opinion or experience of this?|

|If it were me, I would amend, but go easy on the ammonium sulfate. Then add the compost, wait a bit and then retest. I think it would be best to be conservative, retest and then amend more rather than add too much of something and have to try to correct it.

|If the soil test was done by the university, they will normally include info as to what you can add and how, for the nutrients which are deficient.
