S.E. Minnesota | Where are you guys getting synthetic gypsum from and what are you paying for it?
Our fertilizer supplier only can come up with pelleted mined gypsum at around 200/ton.
I've been researching gypsum on the internet but just haven't come up with suppliers or prices. |

Eastern VA. No such thing as too many Magnums. | Ours comes out of Richmond, VA for about $20-something/ton. Looks like ruddy-yellow lime. Dang if I can remember the name of the outfit. Coastal AgroBusiness out of Millers Tavern, VA sets up the loads for me. http://www.coastalagro.com/contact/locations.html

Central Wisconsin | Out of Kenosha, Wi. Last spring Del to Central Wi About $40/ton. Would think to SE Mn Maybe $75ish?. If you need a number send me a email |

SE ND | Anyone know of coal plants that produce it in Minnesota or the Dakotas? |

Eastern Ohio | I know where there's tons that are going into a landfill in Eastern Ohio.

North Central Ohio, across the Corn belt ! | on every farm in Ohio could be But what would that do to the co-ops business ? something to think about |

Seneca Kansas 66538 | Dave, why is this going into a landfill? Do they sell the product? Got any numbers? thanks |

| Look here http://www.diamondkgypsum.com/agri.html If 95% is available in California for $70/ton, you should be able to get it to Minn for a little more. This is very high quality spreadable mined gypsum, not the solution grade. Diamond K spreadable gypsum is overpriced for California, we do not see much of it here. I would get a Lab analysis on powerplant gypsum before I put it on my farm. |

Iowa | Need to check for heavy metals. Not all flue gas gypsum is the same or good. |
|
| |
|
central Ohio | Good idea.
How many farmers check on the metal content of lime from the quarry where they pick it up? Just curious. |

North Central Ohio, across the Corn belt ! | Rendell Shira - 1/20/2011 09:14 Good idea. How many farmers check on the metal content of lime from the quarry where they pick it up? Just curious. history shows that natural ground rock is not high in heavy metals yes, there has been testing done for ground rock Lime materials from scrubers, Like gypsum is a differnt isue. a complete analysis of the Product and soil Monitoring is critical. heavy metals from sewage sludge is also an issue and that is why monitoring is done to land where sludge is applied. or should be done. |

Dalton, OH | Dave,
Where is that at? I would love to get my hands on some of it! |

NE Kansas | The byproduct produced by coal fired power plants is also known as Fly Ash. It's used a lot in the construction industry as a concrete modifier. It's also used as a soil amendment in roadways as a subgrade stabilizer in heavy clay soils. The EPA has really cracked down on how it's used in construction and how it's disposed of. I'd be surprised if it's allowed to be spread via a standard lime or fertilizer applicator much longer. For street and highway construction, the states are starting to require an enclosed tiller where the ash is pumped directly into the tiller and mixed into the subgrade. This procedure dramatically reduces the amount of dust created compared to dumping it on the subgrade, spreading with a grader and tilling it in. Here's a link that explains where the Fly Ash, or what farmers know as gypsum or synthetic gypsum comes from http://en.wikipedia.org/wiki/Coal_combustion_products. It should be noted that there are different classes of Fly Ash dependent on the properties of the coal being burned. Coal from Montana has different properties and produces different ash than coal from Virginia. Thus it is important to have it tested prior to spreading it on your farm.

central Ohio | True. I assume all quarries can supply you with a complete analysis if requested.
If anyone on this site has ever had a sample of FGD tested for metals, what did it show?
If ag lime is 35-40% Ca & Mg combined, what makes up the other 60-65%? |

| Fly ash isn't flue gas gypsum. Fly ash is the solid results of burning coal, ashes.
Gypsum comes from treating stack gas with lime to gather sulfur fumes. The reaction makes gypsum, but depending on the fuel there can be heavy metals in that like mercury which I think is the most common.

Eastern Ohio | This is the Sammis Power Plant in Stratton,Ohio. I worked on the construction here for 3 years on this project. Talked to the First Energy Reps the last year we started producing gypsum. No one their would release it until it went thru an EPA proess. Right now a company called US Gypsum is doing all their epa paper work and their is a possibility that they might get the product. Right now it is currently being conveyed on a 3 mile conveyor to the so called "Gypsum landfill". The pile you see in the pit is a gypsum runoff pad for when the conveyor breaks. Right now I'm on another coal scrubber project just 20 miles south of this plant. 2 units are allready producing gypsum, but it is being barged down the river to a drywall plant. |

Iowa | Gerald J. is correct on what he said. |
|

|
| if you would be interested in mined gypsum yet it may be cheaper to get out of FT. DODGE, IA. not sur eon the cost, but I'm pretty sure it is way less than that.
