Hello

I'm generally assessing my soil test, reviewing nutrient improvement, and now looking to improve anything else I can.

I'm doing some comparisons of soil tests from the spring of 2014 and currently and am looking for any input that folks may want to share for perspective. From my perspective, it seems like there has been some marked improvement in certain aspects of the results. Macro and micronutrient levels seems better as does Organic Matter.

If I'm doing my math correctly, for LowB,the soils percent base saturation is a Ca:Mg:K ratio of 2783:556:220 or 76:15:6, putting my Ca:Mg ratio at 5:1

Similarly, for HighB, the Ca:Mg:K ratio is 4700:1013:383 or 76:16:6, putting my Ca:Mg ratio at 5:1.

From what I understand, for a clay soil, you would want to push Ca:Mg somewhere to the order of 7:1

I feel the steps I should take are:
1) get more Caclium into the mix to try and increase that Ca:Mg ratio and spread those soil particles apart
2) add some composted manure and perhaps another source of nitrogen

Is there reason for concern with some of these overlying high ppm values for macro and micronutrients?

hau, Jp,

The biggest concern I see is the ultra high Phosphorus content, everything else looks pretty good.
Phosphorus is used by plants for flower and fruit production, so perhaps adding some calcium would help the ratios a bit.
The single best thing you could do for your soil now looks to be the addition of mycelium.
If you have not made the addition of biochar, that would also be a good thing to add, it will act as a buffering agent.
 
Eliminate 95% of the weeds in your lawn by mowing 3 inches or higher. Then plant tiny ads:
