    We use calcium carbonate 'in our area referred as Barn Lime' which is a little dusty but the cost is about 2.50/bag laid in to our office in semi quantities only.

    Tree we have calcitic lime here, is this the same? I think it's $10-15/50lbs if you can find it.Aren't your soils calcium rich? In the right market, like up here, it's worth alot. Is it powder or pellet? I'm talking pellet.

    Quick lime is Calcium Oxide (CaO) and should be used with extreme care on soil. Quick lime will react quickly with water and form a calcium hydrate. However, if sufficient water isn't available, quick lime pulls water from plants, bacteria, fungi and other living organisms, which can lead to plant death.

    Quick lime will also react with manures and nitrogen fertilizers, releasing the nitrogen as a gas before it can be absorbed by the roots.

    it has ample water, I will find out more about it in the morning, it was a valuable commodity for citrus, then the citrus left and this guy no longer has a way to get rid of his waste stream. he said it went like this.
    CaCO3 → CaO + CO2
    CaO + H2O → Ca(OH)2
    Ca(OH)2 + CO2 → CaCO3 + H2O

    but that it had some (like less than 1%)
    CaSO4ยท2H2O

    Dido to green marks comment. I know some one who was using a form a quick lime in a hydro seed mix. well come to find out it created a crust on the surface of the soil. It threw the Ca/Mg ratio and the pH out of whack. I'd have to dig it out to give specifics but I posted them on here before. It formed a 1/4 inch crust on soild surface and basically choked out the guys bermuda.
