What products, and how much of, do I need per 1000 sf to:
Raise my Magnesium level from 290 to 500 ppm
Raise my Copper level from .2 to 1.5 ppm
Raise my Zinc level from 4.0 to 12.0 ppm
Thanks in advance Ed

according to this site http://woodleaffarm.com/enlivening-soil/ I believe you have to devide the amount for one acre by 43.56 to get the amount for 1000sq ft
Add no more than 10#/acre of 23% copper sulfate every six months to the soil, this will raise soil levels .6 ppm.
10 lbs. of zinc sulfate will raise zinc levels 1.8 ppm. in a clay soil, more is needed in a sandy soil. Don’t add more than 40#/acre of zinc sulfate to raise levels 7.6 ppm.

1/4 lb of copper sulfate (25% copper) will raise you to 1.6
1 lb of zinc sulfate (35.5% zinc) will raise you to 11.7
magnesium addition depends on your PH use mag oxide if PH is low, use epsom salts if ph is neutral to high. but it takes alot of epsom salts to raise the mag levels that much and it can leach easily. you can foliar epsom salts through the season to alleviate any deficiency.
