Here are my fall soil test results from Umass Amherst. Any feedback would be appreciated.

Soil PH 6.9
Lime Index 2 6.46
Phosphorus 173 (lb/A)
Potassium 870 (lb/A)
Magnesium 883 (lb/A)
Calcium 9468 (lb/A)


CMC 16.7(A) (me/100g)

K 6.6 (% saturation)
MG 21.7 (% saturation)
Ca 71.7 (% saturation)

Acidity 0.0
Organic Matter 12.2%

Sulfur 104 (ppm)
Soluble Salts 1.03 (mmhos/cm)
Nitrate-N 31 (ppm)
Ammonium-N 5 (ppm)

The root area is 500 Sqft, and the plants are allowed to grow out over the grass in the yard.

Your ph is good. K,phos,mg and Ca are all very high so try not to increase those.You want to increase Copper,Iron and Mn. The goal would be Mn half the level of Iron.So iron at 20 ppm and Mn at 10ppm. You want copper at half of zinc. So say zinc ot 6ppm and copper at 3 ppm. I suspect youve added a lot of organic to be at 12%-and thats prob. how your ca got so high so I wouldnt add manure,leaves or other compost for at least a season

Thanks cojoe, last year I added a lot of compost which brought the OM up. I've been playing with the Langley soil estimator to try to get the ratios in check.

Your ca/mg ratio is good especially if you have sand or loam
