For those interested, I'd like to start a thread where everyone can post thier Fall soil test results for easy reference at seasons end. I think it would be very interesting to be able to go back next year after harvest and compare all of the test and how well each members plants perform. Having a large group of samples and patch results in one easy to find thread could only help in giving a general idea of where our different types of soil need to be in order to perform well.
Please post your soil test results here .

Recommendations: 65 lbs. N per acre, 40 lbs. P205 per acre, 30 lbs. potash per acre
Garlic, Old Garden, Composted patch, Patch 4&5: Use ammonium sulfate as all or portion of the Nitrogen requirement to reduce PH.
Garlic, Old Garden: For best results apply 20-40# P2O5 as a side placement application.
Composted patch: The phosphorus recommendation was set to zero for environmental concerns. If planted early in the spring, apply 30-60# P205 as a side placement application near the plants will improve availability and stimulate growth.
Patch 4&5: For best results apply 20-40# P2O5 and 20-30# K2O as a side placement application. Substrate from teh amount recommended above then broadcast the rest if any.
Old Garden, Composted patch: Sodium levels are higher than desired, apply gypsum and leaching with water may be beneficial. These are the areas I used the SEA-90 on.
Old Garden, Composted patch: CEC may be over-estimated due to high PH and free lime in the soil.
Composted patch: CEC may be over-estimated due to high potassium levels.
