  • Hot Lime

    Hot Lime

    Hot Lime (or quick lime) for agricultural applications.

    A mineral with chemical formula CaO, and is commonly called quick lime, burnt lime or hot lime. It is made by heating limestone (CaCO3) to drive off carbon dioxide.

    Quick lime is used in preference to normal Ag lime or slaked lime for agriculture applications in some horticultural crops especially for treating clubroot. Hot lime is a faster-acting lime and has the highest neutralising value (NV) compared to other forms.

    When hydrated with one mole of water, Hot lime forms slaked lime, Ca(OH)2. Hot lime generates heat when it becomes slaked with water and therefore speeds up the reaction to form calcium in the soil.

    Quick Lime is more concentrated and caustic than agricultural lime and unpleasant and dangerous to handle, so couple this with a higher cost and its use is not commonly used in general agriculture such as broadacre and pastoral applications.

    For reference Slaked lime (or hydrated lime) is calcium hydroxide Ca(OH)2 and has a higher neutralising value than agricultural lime but is more expensive and not usually used in broadacre and pastoral application.

    Pacific fertiliser can supply quicklime, hydrated lime and normal ag lime in bulk. bulkbags and pallets of 25kg bags.

    Types of Lime:
    Agricultural lime (calcium carbonate)
    Quick lime (calcium oxide) – also called caustic lime, hot lime, burnt lime and unslaked lime
    Hydrated lime (calcium hydroxide) – also called slacked lime. Bulk seconds called Meadowlime
    Dolomite – Pure dolomite is 54.3% CaCO3 and 45.7& MgCO3
    Dolomitic Limestone or Magnesian limestone contains magnesium carbonate much lower ratios compared to dolomite eg the MgCO3 content may range approximately from 4.4-23%.
    Magnesite (magnesium carbonate)
    Burnt magnesite MgO (magnesium oxide)
    Wet lime (their usefulness is determined by the NV and water content)
    Granular Lime – granular limestone, prilled limestone or pelletised limestone
    Lime and cement kiln dusts (their NV varies from 70–150 and Ca 25–54%. Mg is usually less than 1%)
    FLUID LIME- liquid lime. This product is made by mixing very finely ground limestone (suspecnsion lime or ultra fine lime) with either water or liquid nitrogen fertilizer along with a suspending agent (attapulgite clay) and applying with a liquid fertiliser applicator.
    SLAGS – Steel industry byproduct mainly is magnesium silicate or slag
    FLUID-BED ASH- Byproduct of electrical utility companies from mixing limestone into ground coal in a fluidising bed. Also called stack dust.
    Gypsum (calcium sulfate) – no or limited NV value
    Limestone effectiveness – An expression of aglime effectiveness is based on the combined effect of chemical purity (CCE) and fineness. The ECCE is determined by multiplying CCE by factors like particle size (fineness.) Also referred to as effective neutralising value (ENV), total neutralising power (TNP), effective neutralising material (ENM) and, in the US “lime score”.

  • Triple Super Alternatives

    Triple Super Alternatives

    Triple Superphosphate (TSP) product is no longer stocked in large volumes in Australia and TSP is mainly used in blends.

    The products that are being used in its place are TriplePlus/Tresspass fertiliser  (TSPS), Double Super Phosphate (DSP or PastureKing), Monoammonium phosphate (MAP) and Single superphosphate (SSP).

    Triple superphosphate, while not chemically pure, can be thought of as monocalcium phosphate (MCP), which has the formula Ca(H2PO4)2.H2O.

    Single superphosphate is comprised of approximately two-thirds gypsum (CaSO4.2H2O) and one-third  MCP.

    The chemical formula for MAP is NH4H2PO4

    MCP and MAP both dissociate to release H2PO4+ ions, so in this respect there is no difference in the products.

    MAP and MCP vary in their solubility in water:

    • MAP        37 kg/100 L
    • MCP        2 kg/100L.

    The gypsum in single superphosphate (SSP) makes this product less soluble and more difficult to dissolve. Gypsum has a solubility of 0.26 kg/100 L, about one-eight of that for MCP.  Gypsum also has no effect on soil pH.

    The solubility of gypsum is comparable to that of Burnt and Hydrated Lime, and is much higher than that of ground limestone:

    • Calcium Carbonate                 (Lime)                                             CaCO3            0.0013 kg/100 L
    • Calcium Oxide                          (Burnt or Quick Lime)                CaO                0.13 kg/100L
    • Calcium Hydroxide                 (Slaked or Hydrated Lime)        Ca(OH)2           0.17 kg/100 L

    Super Spreading

     

    Superphosphate SSP (8.8% P)
    This is produced by treating rock phosphate with sulfuric acid, and is the most commonly used phosphorus fertiliser.

    Double superphosphate DSP (17.5% P with 5% S)
    Phosphoric acid is used instead of sulfuric acid in manufacture.

    Triple Super Sulphur  TSPS (18% P) with 10% S)
    Compound granule of triple super and elemental sulphur.

    Triple superphosphate TSP  (20% P)
    Phosphoric acid is used instead of sulfuric acid in manufacture.

    Monoammonium phosphate (MAP 21% P); Diammonium phosphate (DAP 20% P)
    These two fertilisers are produced by treating phosphoric acid with ammonia.

    Rock phosphate (10% P)
    Crushed & mill soft rock phosphate is sometimes used as a fertiliser but is very insoluble. Reactive phosphate rock (RPR) can be more soluble than crushed rock phosphate where there is acid soil/sulphur.

  • What is Gypsum

    What is Gypsum

    Gypsum (CaSO4· 2H2O) is a soft white, grey, brownish or slightly pink mineral consisting of hydrated calcium sulphate also know as calcium sulphate di-hydrate. It occurs mainly in sedimentary deposits and is used to for soil amelioration and in building construction materials.

    Gypsum is moderately water-soluble (~2.0–2.5 g/l at 25 °C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures.

    Gypsum is generally found in mineral and rock form, but there is also recycled, synthetic and byproduct forms of gypsum.  Mined gypsum is a very soft mineral and it can form very large colored crystals.  Natural gypsum is found in many parts of the world. Gypsum deposits lie in flat beds of about six to eight feet in thickness, and are often inter-layered with limestone or shale. Gypsum deposits were formed millions of years ago when salt water oceans covered most of the earth, and as they receded, may inland “dead” seas were formed which, as evaporation continued, became more and more salty. As those salts precipitated, they formed various compounds in turn, one of which was gypsum. As millions of years passed, these salt deposits combined with decayed vegetation and other minerals, and eventually the result was stratified rock, with layers of gypsum and layers of limestone alternating, the whole covered over with many feet of glacial deposits. The result is the accumulation of large beds of sedimentary gypsum near old salt lakes and inland river beds.

     

    The main types of gypsum in the market place for agricultural, civil and industrial application are:

    Natural gypsum: is mined from the ground as a mineral and sold for industrial, medical and agricultural uses. Generally the mined gypsum will be selenite gypsum which is an opaque sandy crystal gypsum. There are various grades of mined gypsum and it is essential you determine you are getting the best bang for your buck. The easiest method of comparison is gypsum purity or each gypsum source available to you.

    Recycled Gypsum: is derived from plasterboard waste and is a high quality source of gypsum. The product has a granular feel making it easier to spread. The granules porous structure increases the surface area making the recycled gypsum more soluble. Read more.

    Synthetic gypsum (Not Sold by PacFert): industrial gypsum, FGD (Flu Gas Desulphurised Gypsum) and DSG (Desulphurised Gypsum) are all names for gypsum which are created by through chemical processes and not mined virgin product. Synthetic gypsum is most typically created in scrubbers, using lime (Ca), in coal fired power plants to clean the sulphur (SO) from the smoke stacks. The lime and sulfate combine and make synthetic gypsum (CaSO4· 2H2O) which is a high quality and very pure gypsum material. Chemically this gypsum is identical to natural gypsum.

    Phosphogypsum (Not Sold by PacFert): refers to the gypsum formed as a by-product of processing phosphate ore into fertilizer with sulfuric acid, such as Phosphate Hill in Central West QLD. REGYP DOES NOT SELL Phosphogypsum in Australia. Phospho gypsum is produced from the fabrication of phosphoric acid by reacting phosphate rock with sulfuric acid. Phosphogypsum does contain moderate levels of heavy metals including cadmium and REGYP recycled gypsum products DO NOT, so the two should not be confused. Phosphogypsum is radioactive due to the presence of naturally occurring uranium and radium in the phosphate ore. Marine-deposited phosphate typically has a higher level of radioactivity than igneous phosphate deposits, because uranium is present in seawater.
