Soils that are most likely to show economic responses to gypsum application have the following features in the topsoil, subsoil or both: high clay content—greater than 30%. particularly greater than 40%, high sodicity level—ESP greater than 5. particularly greater than 10, low salinity level—electrical conductivity of a 1:5 soil: water suspension (EC I:5) less than

If soil tests indicate low levels of sulphur it may be necessary to apply gypsum. Gypsum contains calcium and sulphur. The sulphur assists nodulation in legumes present in the pasture and animals with the digestion of plant material. Where gypsum is applied soil surface conditions generally have a softening of the soil surface increasing moisture
Tests have shown that canola removes approximately 10 kg of sulphur from the soil for each tonne of production. Therefore at least that amount of sulphur must be available to the canola plant to achieve maximum production. Gypsum is a very economical source of both calcium and sulphur. The sulphur in the form of sulphate
Gypsum (calcium sulphate) is a very economical source of both calcium and sulphur. The sulphur in the form of sulphate is readily absorbed by the plant. Application rates will vary according to nutrients already present in the soil and a soil test to check for all nutrient requirements is highly recommended. However, 0.5 to 1
The three important factors in applying gypsum are method, rate and frequency of application. In considering these factors much depends on whether the agriculture is dryland or irrigated, whether the topsoil or subsoil (or both) is to be treated and the nature and extent of the problem. General Application Methods 1. Irrigation, the most immediately
To calculate the fertiliser application rate required for a particular nutrient application rate, use the formula: ReGyp screened gypsum products contain approximately 17% of sulphur (S). Application Rate x % Sulphur = Sulphur application rate (kg/ha) Sulphur Kg/ha = 1000 kg/ha x 17 = 170 kg/ha ReGyp screened gypsum products contain approximately 17% of sulphur
To obtain the total cost of supply and application of gypsum per tonne of pure CaSO4.2H2O, the following information is required: A. the landed cost at the farm gate of gypsum per tonne (gypsum + freight); B. the cost of spreading or mixing in irrigation water per tonne of gypsum; C. the purity, as percentage
In deciding which gypsum to buy, the main points to consider are: the total cost of supply and application of gypsum, expressed on the basis of pure CaSO4.2H20 (Regyp - 90%+ pure), how quickly the gypsum dissolves in water (Regyp - up to four faster), how easily and evenly it spreads (Regyp - up to 30%
There are three main ways in which soils can be tested for likely gypsum response. These are: 1. On-farm tests, these are the quickest but least reliable means of assessing likely gspsum response. The simplest test is to drop about eight small (3-5 mm diameter) air-dry aggregates of soil into a container of rainwater or
