Please see this years soil analysis. I think I've lost a little ground from last year, but would appreciate the feedback. Started getting many compliments on the lawn last year Thanks for all your help!

Re: Spectrum's 2020 Soil test
Spectrum. I continue to be amazed by that OM number on Cape Cod. Just awesome! The TEC is a little bit sandy, but I'm not messing with success on Cape Cod.
It's an easy year for you. Potassium is short, so find Sulfate of Potash (0-0-50, "SOP"). Not easy. 2 lbs/K monthly, Apr - Sep.
Bay State is fine as a fertilizer - stick with it.
Phosphorus is good.
Iron is good, and available at your pH.
In the micro's, Boron and Manganese could use a tap - up for it in 2020?

Re: Spectrum's 2020 Soil test
Thanks so much for your reply Andy.
Given how consistently high the organic matter has been for the past three years, I'm delighted to see that it has to be real. I even sifted the soil samples through a flour sifter to make sure all grass roots and tiny twigs were removed. I'm attributing it to purchasing good top soil.
I'm surprised to see potassium is now low. 3 years ago it was twice the upper normal limit and have therefore been avoiding anything containing potassium. I will research into sourcing SOP for my area. Could I get away with a 10-10-10 fertilizer or do you think it may add to much phosphorous?
I was adding boron last year via "20 mule team" borax, but clearly was not doing enough. I will keep going with it. I have a fertigation system and may even try using it to apply the 20 mule team borax.
How do I add manganese?

No. You have plenty of Phosphorus, and no more goes down. Even from 10-10-10Could I get away with a 10-10-10 fertilizer or do you think it may add to much phosphorous?
Please don't consider adding more per app, or more apps. Boron is required at very low PPM, and toxic just slightly above the required range. It's not one to play with.I was adding boron last year via "20 mule team" borax, but clearly was not doing enough
Get Manganese Sulfate from EBAY or Amazon. The rate and application method are identical to the Boron.How do I add manganese?
