So my soil test results show that I'm severely deficient in Magnesium and so I googled it and many suggest Epsom salt but they don't really tell how to apply and how much is needed for a area of 5000sqft.

Can anybody help ?

The first link tells us that magnesium sulfate(epsom salts) is 9.8% magnesium, so you can do the math with what your desired level is and square footage of your patch. I found, after a Google search, several articles where Ron Wallace cites the use of epsom salts in his patch.

My question to Ron would be: What other nutrients do want magnesium to be in ratio with and what are those ratios(if any)?

Last year, I ordered from the company in the third link above with free shipping on 100 pounds of it.

Brosco acoording to your other post your PH is 5.8, a high magnesium content dolomitic lime would be better than epsom salts for the initial boost you need. But where as you have sandy soil the change will be realitivly quick and require less lime than most other growers. it will also be short lived. from 5.8 you can add 250lbs of dolomitic lime to 5000 sq ft and this will put you just above 7 PH. your magnesium would be around 200 ppm from this addition.
your calcium was severely low. the lime will help a little but not enuff. gypsum should be added also. you coul do a split application on gypsum of 250# in the fall and 250# in the spring.this will put your calcium in the 1000ppm range.
But the big issue is that you have no idea of where your micronutrients are. i would recommend sending out for a complete test. A&l Labs west, agrienergy, western labs, Umass, Logan labs are am few to mention. If cost is the issue Umass and Logan labs are around 20$ for full test. the others are a little more.

Thanks Bry you are reading my mind 100% as that was my attack plan. I just want to be careful of how much lime I put in cause my ph was about 6.6 last spring so I don't want to over do it cause I know that it will naturally rise in the spring any ways. With my sandy soil Im thinking that some good compost is needed and I have 3 or for big piles in the back with maple leafs and grass clippings thats around 3 years old.

My biggest issue is that I know I need organic matter to hold onto my nutrients better but I also know that once I start to add it my levels of all nutrients will start to go up automatically so I don't want to start adding too much pure amenities.

I'm going to add this yet this fall:
200lbs lime
50lbs epsom salt
200lbs gypsum
3 or 4 compost piles
(I already added potash)

Thanks for the sites "down and out" ill check them over


"O and So Cal, I don't use that whole space for my patch cause I also grow tomatoes,Beans,Cabbage,Peppers,corn,broccoli,brusselsprouts,potatoes,lettuces,cucumbers,squash,blueberries,black berries,strawberries,grapes,apples,peach,plumb and pears.....i'm sure im leaving others out but thats all I can think of" :)

Brosco, Bryan offered very good advice but he is a humble guy and did not mention to use his soil amendment calculator. It can be found under the resources tab on the GPC site (http://greatpumpkincommonwealth.com/index.php/resources). It is a phenomenal tool when your trying to calculate the impacts of amendments on your soil.

Thanks Steve.

I have heard there has been some issues with downloading the calculator. It will not open. If this is the case and you wish to use it Brosco, email me at bryan_langley
@amat.com. I'll send you a copy
