As a few of you may know, I retired from the urban forestry side of things a couple of times and at age 70 decided to do what I originally studied in college in the 60's. I work for a forest management company that has several walnut plantations here in Illinois. It is interesting trying to recall what you learned that long ago and then filed away.
This thread is a spin off from Jim and Dave's highly popular Sustainable Ag discussion. It deals with two fields, side by side, same soil type and fertilization regimen (100#N - 25#P aerial applied this past spring). The differences are that one was planted in 2009, the other in 2011 (hint: reverse the fields based on your first inclination), and one was in standard corn soybean crop rotation prior to planting while the other was a pasture with Osage Orange and multiflora rose cover that was bulldozed prior to planting.
I had a Haney Soil Health evaluation done with samples taken from the grass area you can see in the two side by side photos. I did this to be sure that chemical applications in the tree rows and such would have less effect (I think). In the results, Cooper is the best looking site. I will also include a document on interpreting these tests.
What do you think????
