>>It says the soil is "very rocky loam", and I think the low CEC on
the analysis means it's NOT clay, <<
very rocky loam is right in the middle --not clay or not sand- it is the
best soil type The very rocky is just an incontinence in a vineyard.
Your soil analysis suggests a 3.5P to 1 K ratio. nitrogen around 1 but
nitrogen is easy to add in the form of ammonium nitrate( 33% N )as it is
water soluble and will incorporate easily with rainfall. It does not have to
be added before planting as with new plants it can be added a couple
tablespoons per plant after planting several times the first year==about 12
inches away from the plant stem.
Do not add any fertilizer in the planting hole. The incorporated fertilizer
will suffice. Do not add any fertilizer after Aug 1 so the new vines will
harden off before freeze up.
Some may suggest adding compost at planting but I would not add it in the
You may not find a fertilizer at your farm supply in the actual ratio you
want but they should carry super phosphate ~42% which you can add by itself
to bring up the P to the desired level . Hopefully you and find a 1=4=1
You may notice that I seem to key on the phosphorus. Phorohorous does not
move readily in the soil so I want to get it incorporated deep into the soil
BEFORE planting, Nitrogen moves very readily and potassium is somewhat
slower but it does move
My suggestion is to incorporate the lime and P as deep as you can in the
vine row and whatever K you can add also
If you have a local farmer that can subsoil at least 12'deep or more in the
vine row it will loosen the soil and incorporate the P and lime. You will
only one chance to prepare the seed bed.
DO NOT WAIT until spring to contact a farmer as they will be very busy.You
can subsoil anytime he can get to it unless the ground is so frozen he
can't get the implement in the ground > 3". Actual frozen ground allows more
soil shattering which is what you want
