I suppose this started more as curiosity than a real "need". On our farm, with the newer "Variable Rate Technology", the soil is sampled in 2.5 acre grids every 2 years. We've found that we are able to significantly increase production by knowing exactly what the soil needs.
Anyway, I've always been curious about the fertility of our yard and garden. So, we decided to take soil samples and get them tested by the local soil and water conservation office.
We took several cores from our yard, and combined them into one sample.
Then, we took several more cores in our garden for the second sample.
Here are the results
First the yard...
Then the garden...
A couple of things are interesting about these results:
1. Large difference in pH between the two samples. The garden has only been in production for 2 years. Why would there be such a difference?
2. There is always lots of discussion about how lawn phosphorous levels are often too high. This yard has been here for 30 years. I'm surprised that it is a bit low in phosphorous.
As usual, we made a family affair of this project.
Here are some videos of the entire project.
First, gathering the samples:
Next, apply the lime. Had to use some creativity to get this done.
Finally, remove the depth stops on the King Kutter tiller and till it as deep as possible.
So, get some popcorn and enjoy...
