Abstract:
To reduce leaching of phosphorus (P) from fertilised pastures to shallow estuaries in the high rainfall (>800 mm annual average) areas of south-western Australia, and to supply extra sulfur (S) for subterranean clover (Trifolium subterraneum L.) in pasture, 'coastal superphosphate' was developed as a possible alternative P and S fertiliser to single superphosphate. Coastal superphosphate is made by adding phosphate rock and elemental S to single superphosphate as it comes out of the den before granulation. It has about 3 times more sulfur (S) and one-third the water-soluble P content than s

Abstract:
Phosphate rock is the basic material used in all phosphorus fertilizer production. In Myanmar, phosphate rocks are found in Shan State, Mon State, Kayah State and Mandalay Division. In this work, phosphate minerals as phosphorite samples were collected from Thabeikyin area in Mandalay Division. The phosphorite mineral consists of 8.59 % of P2O5 which is modified by wet screening and hydroseparation method to upgrade the phosphate content. Phosphate fertilizers; phosphoric acid, normal and triple superphosphate were prepared from upgraded phosphate powder (14.56 % P2O5) by using concentrated su

Ryegrass persisted in all treatments, but was only dominant in the superphosphate treatments, unsown grasses dominated in the no superphosphate treatments. White clover was more common with superphosphate, and both cocksfoot and timothy required adequate superphosphate in order to persist. Over 60 years of measurements, yields

Composting is an environmentally friendly method for transforming the nutrients present in livestock manure into organic fertilizer. In this study, the compost quality-enhancing and N2O and CH4 emissions-reducing effects of superphosphate were investigated during industrial-scale in-vessel composting of swine manure. Alongside a control group, three different doses of superphosphate were tested: 5% (SSP5), 10% (SSP10), and 15% (SSP15). The results revealed that the superphosphate reduced the N2O and CH4 emissions by 18.5–26.3% and 15.8–25.1%, respectively. In addition, the superphosphate enhan

Abstract:
In the manufacture of superphosphate by the acidulation of phosphate rock with sulphuric acid, fluorine is evolved, mainly as silicon tetrafluoride, along with carbon dioxide and steam. This environmentally unacceptable fluoride is required to be removed before being vented to the atmosphere. This is usually done by absorbing the gas in water. However, industrially the absorption is complicated by the presence of entrained phosphate rock dust, mist particles and condensing steam in the gas stream, and by the silica formed from the reaction between silicon tetrafluoride and water.

Abstract:
Single superphosphate is derived from chemically treating rock phosphate into relative proportions of monobasic, dibasic and tribasic calcium phosphate to produce a commonly used source of phosphorus fertiliser for pasture systems. The leaching of phosphorus on susceptible soil types contributes to eutrophication and environmental damage. By modifying the chemistry of single superphosphate to match a soils phosphorus binding index and rainfall conditions, pasture dry matter yield can be maintained and leaching of phosphorus significantly reduced.

Heat-exchange equipment is known to play a very important role in chemical industry. Two processes are used to produce phosphate fertilizers: run-of-pile and granular. The granular process uses lower-strength phosphoric acid (40%, compared to 50% for run-of-pile). The reaction mixture, a slurry, is sprayed onto recycled fertilizer fines in a granulator. Granules grow and are then discharged to the screen, crusher, cooler and sent to storage. Thus, the multistage fluidized bed can be used for granular solids cooling.

Abstract:
The article deals with the effect of nitrogen fertilizer on the yield of different cultivars of winter wheat. Field experiments were conducted in 2011–2013 at the Experimental Station of Aleksandras Stulginskis University in carbonate shallow gleyic leached soil, (Calc(ar)i-Epihypogleyic Luvisol). The object of the investigation was winter wheat cultivars ‘Zentos’ and ‘Ada’. In sowing time the wheat was treated with granular superphosphate (P60) and potassium chloride (K60), and in spring, after the vegetative growth had resumed, in tillering time (BBCH 23–15) with ammonium nitrate (N60).

Abstract:
The paper investigates the effect of nitrogen fertilisers on the amount of photosynthetic pigments in winter wheat leaves. The research was carried out in the period between 2012 and 2013 at the Experimental Station of Aleksandras Stulginskis University in carbonate shallow gleyic leached soil, (Calc(ar)i-Epihypogleyic Luvisol). The object of investigation: winter wheat cultivars ‘Zentos’ and ‘Ada’. Granular superphosphate (P60) and potassium chloride (K60) fertilisers were spread during sowing, while amonium nitrate (N60) was used in tillering time (BBCH 23–25), after the vegetative growth ha
