Let the jar rest for about 5 to 10 minutes. If the water is still milky and not clear, then your soil will benefit from an addition of gypsum. Gypsum changes the soil composition through a process called flocculation. The gypsum enables the small and dense clay particles to join together to form bigger particles, more closely resembling loose sand2. Another occasion when gypsum is often introduced in a garden setting is if the soil in your garden lacks calcium. For gypsum, 1 cmol. c weighs 0.86 g. Therefore, to replace all the sodium in 1 kg of a soil containing 10 cmol c/kg of exchangeable sodium would require the addition of 8.6 g of gypsum.
