Liquid Gypsum

(1 customer reviews)


Instant-action soil flocculant


Develop a crumb texture in your soil by flocculating the clay. A convenient alternative to ploughing or back-breaking digging!


Waterlogged Soils

When clay soil is compacted it forms a ‘cap’. Clay caps prevent rainwater from quickly dispersing during periods of heavy rain and is one of the main causes of waterlogging.  Apply Liquid Gypsum to flocculate compacted clay soil and improve drainage. Liquid Gypsum is a great option in situations where deep ploughing is not an option; such as gardens or no-till farmland.


To treat soil susceptible to waterlogging apply diluted Liquid Gypsum as per the instructions below.


EUTREMA’s LIQUID GYPSUM IS THE ORIGINAL. Invented by our founder Dr Russell Sharp in 2016. We formulate it in-house to our high standards.


When Liquid Gypsum is applied to the soil, the clay particles in the soil are attracted to its large positively charged calcium ions. This process creates the soil ‘flocs’, and a well-flocculated soil is preferred because it will be composed of large soil aggregates that allow water and air to penetrate, and thus improve drainage and aeration.


Degraded soils that respond well to Liquid Gypsum addition include; compacted soils, salt-damaged soils, and clay-dominated soils. However, as all agricultural soils contain at least some clay, they should all respond positively to the addition of Liquid Gypsum.


Unlike other gypsum products, Liquid Gypsum is a solution, so it acts instantly to flocculate the soils. This makes it 2000 times more instantly effective than granular/suspension products. You also do not need to worry about blocked filters and nozzles, which can occur with suspended gypsum.


Application protocol

Watering can: 250mL / 5L watering can. Use sprinkler to get an even coverage of the soil surface. One 20 litre polycan is advised to treat a 500m2 garden (lawn or beds).


For best results on waterlogged gardens, use in combination with Eutrema Clay Drainer.


Pre-planting: apply at 5-20L / ha in plenty of water. Rate can be increased depending upon the state of the soil and the level of bound phosphorus. Adjust water volume to tailor how far into the top soil you want the flocculation to occur.


In crop application: Apply 5L in 200L of water using a sprayer. Follow applications with a spray of fresh water to knock excess product off the leaves. Do not apply in very hot weather or during mid-day sun in the summer.

    Helped improve the drainage on the lawn. Our soil is very heavy clay and so drainage is poor in winter after torrential rain.
    Grass seemed to be a luscious green in the weeks after application too (compared to the small bit we left untreated)!
