Do you just put it on top of the soil? Do you water it afterwards?** A: Oooh, you really don't want me to answer that, because I am something of a nutcase on the subject. A year ago I moved into a place with terrible heavy clay soil over builder's rubble, with a seam of clay under that, and wanted to dig the beds once, then never again. So I have dug out every scrap of soil, 3 feet down and riddled (sieved) it all to get out the rubble and break it up, mixed the gypsum into each bucket-load of soil and put it all in a dumpy bag. Then broke up the clay seam at the bottom of the trench with a mattock and poured in a good thick drainage layer of the smaller rubble, more gypsum in the form of wetted offcuts of new plasterboard and a load of conifer trimmings (will break down slowly, add some organic material and in theory some acidity, also gets rid of the conifer trimmings). I then then backfilled with the treated soil and at least an equal quantity of well-rotted manure. I am now in my second season and the beds are a dream - light, well-drained, ridiculously fertile, and packed with worms - more than I have ever seen in any soil. I have just added a mulch of more manure and loosely turned it in, but that is it. I have set up supports so that I can lay a plank across and not put any weight on the surface of the beds. So - you may not have wanted to hear all that - but I did read somewhere that gypsum will eventually wash out of a soil, so my approach was the use it to initially condition a clay soil (fertile, but otherwise a total nightmare), then maintain the condition with lots and lots of organic material (effectively stopping the clay from clumping together again) and let the worms do the rest. And I am an old bird - a retired nurse with messed up wrists and shoulders, so not some big strapping chap - but I would do it all again to know that this is it forever, and there isn't anything I can't grow, as it also means that I can control the pH in different beds for different plants and crops. Sorry - as I said, you really didn't want me to answer that! **Q: can you please let me know HOW to put the gypsum?? do i dig the soil & turn it over (this is difficult). or just on top of soil.** A: Gypsum penetrates more easily than lime so deep working was not recommended. I forked the ground down to about 6 inches and broke the bigger clods to 2-3 inches. The gypsum was fine free flowing and easy to apply evenly, at 5oz/sqyd. Compared to lime it went into the finest cracks without caking. **Q: My home was built recently and the garden is about 8" of topsoil over clay, when it rains the lawn is sodden. What's the best method of application?** A: I removed the topsoil, into large bags, sprinkled a good layer of gypsum onto the clay (impossible to dig it in) and then replaced the topsoil, also mixed with gypsum. It worked well...no puddles! **Q: Is this product plain Gypsum or are there more substances added? Do you have some experience with mushroom cultivation with this product?** A: is this 100% pure or does it have anything added to it? (I want it for mushroom cultivation) ## Frequently Bought Together - British Gypsum for Agricultural Amendment, Amend Very Compact Clay Soils, 25 kg Bag - Zinc Products Vitax Clay Breaker 10kg Tub | Breaks Up The Heaviest Clay Making Soil Easier To Work - 6X Natural Fibrous Fertiliser 1 x 15kg bag --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/49283296-british-gypsum-for-agricultural-amendment-amend-very-compact-clay-soils](https://www.desertcart.com.ar/products/49283296-british-gypsum-for-agricultural-amendment-amend-very-compact-clay-soils) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
