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
The NSW Waste Avoidance and Resource Recovery Report (WARR) 2008, stated that by increasing the cost of disposal of each tonne of waste, the expanded levy provides an incentive to provide recycling and resource recovery solutions. The levy will also provide revenue which will be used to fund new or expanded environmental programs in NSW.
In 2004 NSW DECC also undertook studies to estimate the the quantities and composition of mixed C&D waste disposed at Sydney landfills. Plasterboard waste was estimated to be around 4 percent of the total C&D waste stream with an expected tonnage range of between 10,000 and 25,000 tonnes per annum. The DECC testing called anything
Gyprock & Plasterboard Waste is 100% Recyclable The ReGyp recycling solution assures that the gyprock and plasterboard waste is 100% recyclable. The recycled gypsum powder which makes up to 94% of the waste, can used in industrial and agricultural apllications. The paper with related contaminants which makes up 6% of the waste can be reused
Article - RecyclingToday - DEALING WITH GYPSUM - 8/6/2001 There is a lot of plasterboard produced in the US. In total, about 15 million tons of new plasterboard is produced each year (2000). California alone uses more than 10% of the nation’s total, or about 1.8 million tons per year, according to the state Waste
