Date Posted Pumpkin Farm Going Green Midwest Laboratories soil test 9.0 organic matter 84 ppm low phosphorus 101 ppm strong bray phosphorus 1851 potassium 577 magnesium 2800 calcium 175 sodium 7.0 ph 24.3 cation exchange capacity percentage base saturation (computed) 19.5 k 19.8 mg 57.6 ca 0.0 h 3.1 na 161 ppm nitrate-n 290 pounds/A 176 ppm sulfur 37.4 ppm zinc 12 ppm manganese 45 ppm iron 7.6 copper 1.9 ppm boron excess lime low soluble salts 1.9 mmhos/cm
blame it on the wife but she put to much Epsom salts on the garden not understanding what amount I said
water soluble report 189 ppm P 1078 ppm K 232 ppm CA 77 ppm MG 181 ppm NA 199 ppm S
I BELIEVE I NEED more calcium and am not sure when or how much Nitrogen I should add. This is where I grew my 1st place pumpkin last year and I will out of necessity be planting there again in 2014. I am in the process of preparing a new garden area for 2015 which is 25 x 100

Your K should be closer to 9% of your base saturation. Cu closer to 2ppm and zink around 5 to 10 ppm.

At transplant time I believe it is recommended to have about 30-35 ppm nitrogen.

I'm a little surprised someone hasn't chimed in on this yet.

just to keep it neat and tidy, here is what I posted on the other thread. Epsom Salts is not (in my opinion) the cause of your high sodium. Its not a Salt, but Magnesium Sulphate (a sulfur)
First, Assuming you got a good sample...and not a hot spot... (you may consider retesting, making sure that you haven't added stuff for at least a month (2 or 3 is better in my opinion) and get a good even sample from soil line to at least 6 inches deep -- for at a minimum of 10 sample sights per 1000 sq feet. Use only CLEAN sampling implements/containers, and NO METAL except stainless steel, Plastic is usually preferred.
It could be due to a large amount of manure you added (assumption due to the Pottasium and OM levels compared to everything else) OR If you didn't add a large amount of manure, did you use chemical fertilizers last year? They are loaded with salt.
That said... While 3.1% NA is not ideal, but it is not a death wish either (but you should do what you can to keep it from continuing to rise -- ie. find the source and reduce/remove its addition). You can also add Gypsum and compensate for the sodium. You are correct at 57.6% Base Saturation CA needs to be raised -- Gypsum will help with that too.
While I am no expert, you should raise the MG (using Epsom Salts) as well to try and compensate for the High Pottasium. (Your base saturation of MG should be close to double that of the Pottasium) Since yours is so large of a difference, I don't think you will be able to get it there all at one time. Others may have better ideas of what is possible.

It was suggested that I apply 240 pounds of Gypsum and 5 pounds of manganese sulfate 32%, 3 pounds Borax, 25 pounds Alfalfa Meal, 10 pounds Blood Meal and 25 pounds of kelp meal to this 1000 square feet sample!
Do I apply it now or in April when I will start my Cantaloupe and watermelon. My Pumpkins will be started on June 10th.
