Where to Get Calcium Sulfate?
The recommendation coming with a soil test suggests me to add calcium
sulfate to a part of my lawn. But I cannot find it in Home Depot or local nurseries. Where can I find it? Is it a part of other commonly available products? Thanks in advance for any info. Jay Chan |

Portland cement is also calcium sulphate, but it is probably more expensive to buy it as such. Lawn gypsum is best, pricewise. |

Portland cement is also calcium sulphate, but it is probably more
expensive to buy it as such. Lawn gypsum is best, pricewise. I bought a bag of 40-lb gypsum from a local nursey for only $8. This is $4 cheaper than what I found in an internet mail order site. The downside is that it has been sitting outside and is wet. This means I cannot spread it right away. I probably need to dry it under the sun for a couple days before I can use it. Oh well...

You got ripped off. $8.00 is too much for a dry bag.
How much do you consider as a reasonable price for a 40-lb bag of gypsum? You may be getting it from a farm supply store. I don't know any farm supply store nearby. The closest farm land is multiple-10-miles away. I can only get it from local nurseries. I guess this means I will have to get it where I can find it. Jay Chan |

Look for Gypsum.
Thanks. I will try again and look for gypsum instead. Jay Chan |

Mix gypsum 50/50 with powdered lime for the best results. The
gypsum will loosen the soil and neutralize calcium chloride salts. Jay Chan wrote in message m... Look for Gypsum. Thanks. I will try again and look for gypsum instead. Jay Chan |

gypsum will loosen the soil and neutralize calcium chloride salts. Thanks for the advice. But the soil test recommendation sheet explicitly states that I don't need to apply limestone in this year. I will pass on limestone at least for this year. I will do a simple pH test next year to see if I need it. Jay Chan |

Forgot . .. gypsum will also bind "sodium" chloride salts! You're
quite right about not always needing calcium. Local conditions apply. Jay Chan wrote in message om... Mix gypsum 50/50 with powdered lime for the best results.
