Probably you will think this is a stupid question, but, what is Gysum?...anything close to Gyproc?? I have never heard tell of this stuff. (I admit I am feeling quite dumb about it) (:

Here is a link to information about the type of gypsum I applied to my patch this fall. Very cheap: http://literature.usg.com/pdf/IG220.pdf

Gyproc sounds like a trade name. How old is your house? Plaster walls? If not, then you probably have gypsum wallboard. AKA Sheetrock. The layer that gets painted is paper. The stuff between the 2 paper layers is Gypsum or Calcium Sulfate. Mined from the earth.

Topsfield, Ma.

It's benefit as I understand it, is that it works down through the soil opening up air and waterways. Anyone want to support or refute this ?

I talked to one gentleman out Altoona that actually puts sheetrock extras on top of the garden, breaks it up, and tills it in.. Very cheap source of gypsum, and it is the same exact stuff you buy in the bag for 8 bucks a bag. The paper either mulches in, or blows away after you till it.

So what is the going rate for Gypsum? I can get it for $4.79 for a 40 lb bag. Is this about right?

It does open hard or sodic soils. Thus also causes salts to leach. That's good, especially in areas that recieve little rainfall. Rates to apply are from 50 - 300 lbs per 1000 sq ft. (soil test first) Delivers calcium & sulfur as plant nutrients. Like Limestone as far as the calcium goes. But unlike Lime, it is non-reactive so it doesn't change the soil pH.

The price you'll pay depends on whether its dust or pelletized and how far you live from the source. There are a couple people who frequent this site that live near the plants & can pick up a single bag for less than $3.00. Around here the going rate is about $8.00 wholesale $12.00 retail. It's all about the frieght baby! Big heavy cheap stuff!
