one of these days I will learn to understand what I'm looking at but until then i'm asking for help. my numbers back from western lab.

pH 7.1
pH CaCl 6.5
soluble salt .35
lime 0.0
%om 9.9
nitrate 36
ammonium 6
phosphorus 227
potassium 820
sulfur 22
calcium 3814
magnesium 490
sodium 39
zinc 5
copper 1.8
manganese 5
iron 71
boron 1....I know this needs to be brought up
cec 16
pbs 212
tbs% 100
cal % of cec 120
magnesium % of cec 26
potassium % of cec 13
sodium % of cec 1

anything special I need to be doing

Add some sulfur to help bring down your pH.

Be careful with boron, make sure you don´t add too much (bringing it up to 1.5 or 2 ppm should be fine).

I agree with Christopher, add some sulfur (but don´t add too much, don´t worry too much about your soil pH, 7.1 isn´t too bad and it could easily become a bit lower as the soil warms up and some of the ammonium and organic matter will be converted into acids).

Also, I would add some epsom salts (perhaps in 2nd half of May, before the plants start to cover most of the patch). Your Ca/Mg/K CEC ratio (normalized to 100%) is 75% Ca, 16% Mg, 8% K and looks pretty good right now, but in my experience Mg is the element which is getting washed out of the soil pretty fast.

Your soil test looks very similar to mine.I'm assuming western lab/Idaho?. I'd do whatever there recommendation on the bottom of report is to tweak cu,mn,iron sulfur,boron ratios.Prob a little manganese and sulfur/sulfate as the plants seem to be heavy feeders of those two. youre dirt is close to ideal so don't f**k up a good thing:)

Thats a good looking report. Add a little B,Mn and Mg.. You could water-in all of it later.....Stay away from K, Ca,&P. and plant that patch. Good Luck

Try using Advanced Nutrient products to help slowly increase the trace nutrients when feeding your plants instead of trying to fine tune your soil.
