  • Elemental Sulphur Blends

    Pacific Fertiliser can blend elemental sulphur (or sulphur bentonite) in with most of its products including phosphate rock and gypsum.

    Benefits of Sulphur:
    • Sulphur is known to improve the metabolism of Nitrogen, Phosphorus and Potassium.
    • Elemental sulphur can be used where sulphur deficiency in soils is known to exist.
    • Application of sulphate sulphur can lower the pH of alkaline soils.

    PacFert

    Pacific Fertiliser can blend many fertilisers, minerals and trace elements including urea, MAP, DAP, gypsum, lime, phosphate rock, elemental sulphur, potassium, magnesium,  cobalt sulphate, copper sulphate, zinc sulphate, manganese sulphate, selenium & silica. We can also blend a high analysis compost with gypsum and other products to meet you needs.

  • BENEFITS OF PHOSPHATE ROCK APPLICATION

    BENEFITS OF PHOSPHATE ROCK APPLICATION

    BENEFITS OF DIRECT APPLICATION PHOSPHATE ROCK

    Organic farming is the fastest growing sector of the global economy. Australia is the largest organic producer globally with 12 million hectares under organic cultivation. Pacific Fertiliser’s organic phosphate fertiliser is environmentally and nutritionally superior to chemical fertilisers and can be used on a wide variety of crops and pastures.

    Organic fertilisers based on rock phosphate such as PacFerts’s products offer several advantages over chemically processed soluble fertilisers such as superphosphate.

    • Organic fertilisers slowly release nutrients into the soil matching the speed at which the nutrients are being absorbed by the plants.

    • Phosphate rock has the ability to restore microelemental and microbial soil balance which in turn leads to less reliance on artificial fertilisers and better crop yields.

    • Use of organic phosphate instead of chemically processed phosphate avoids the serious environmental degradation caused by increased concentrations of fertilisers in the ground water, the rivers and the coastal waters. Use of organic phosphate rock reduces the risk of harmful accumulation of nutrients in the soil and reduces soil salinity problems

    • Plants grown on organic phosphate rock fertiliser have a better nutritional quality.

    • Because of phosphate rock’s unique chemical composition, incorporation of phosphate rock into the soil enhances its biological activity and increases soil carbon (C) accumulation, leading to improved soil fertility and restoration of its physical and chemical properties.

    • Organic phosphate rock is a source of several nutrients other than P. Rock phosphates are usually applied to replenish soil P status, but phosphate rock also provides other nutrients not present in soluble fertilisers. Application of organic phosphate has a potential trigger effect on plant growth and crop yields as a result not only of phosphorus release but also because of phosphate rock’s effect on increasing exchangeable calcium (Ca) and reducing aluminium saturation.

    • Phosphate rocks for direct application can be more efficient than artificial fertilizers in terms of phosphorus (P) recovery by pants under certain conditions. Based on the unit cost of P, natural phosphate rock is usually the cheapest.

    • Phosphate rocks are natural minerals requiring no metallurgical processing. Their direct application avoids production of polluting wastes such as phosphor-gypsum and greenhouse gases, thus resulting in energy conservation and protein environment.

    Pacific Fertiliser also produces other organic compliant natural mineral fertilisers and soil conditioners.

    Note: Soft Rock Phosphate does not contain soluble phosphate, therefore the phosphate availability is a function of acid soil conditions and/or active soil biology, i.e. soft rock phosphate becomes available rapidly in acidic soils. In alkaline soils, it should be combined with REGYP compost, humates, microbial agents. Application rates are generally in the range of 500kg to 1500kg per hectare (Ha).

  • Aerial Grade Phosphate Rock

    Aerial Grade Phosphate Rock

    Pacific Fertiliser’s aerial grade phosphate rock  RPR210 is a granular 2-10mm product that will be available in 2014.

    The product provides minimal dust and very flowable properties, suitable for aerial applications.

    The phosphorous is then released into the soil over a few years providing good long term returns with minimal applications when applied correctly.

    PacFert can also blend this with prilled gypsum and/or prilled lime for a one pass application.

  • Organic Soil Amendments and Fertiliser

    Organic Soil Amendments and Fertiliser

    Pacific Fertiliser sells various types of organic soil amendment products.

    These include:

    – Ag Lime (calcium source and pH adjustment)
    – Gypsum (source of calcium  and sulphur)
    – Soft Rock Phosphate (source phosphorous and calcium with some pH adjustment)
    – Dolomite (source of calcium and magnesium with pH adjustment)
    – Guano
    – Fish meal
    – RPR Reactive Phosphate Rock
    – Fishmeal
    – Sulphate of Potash (SOP)
    – Muriate of Potash (MOP)
    – Kieserite  (Magnesium sulphate)
    – Magnesium Oxide
    – Magnesium Carbonate
    – Humates (brown coal fines)
    – Liquid fulvic and humic acid
    – Blends of the above products and trace elements

     

    PacFert does not have organic certification for its products, but because they are natural minerals mined from the ground they are deemed organic. Any processing by Pacific Fertiliser is to grind, classify or package the products for agricultural applications, which means the natural products are still suitable for organic applications/farms.

     

     

     

  • RPR-GYP

    RPR-GYP

    RPR-GYP is a blend of both Pacific Fertiliser’s RPR2 Phosphate Rock and sub 2mm Mined Gypsum products, that provide an organic alternative to ordinary “super”.

    Unlike conventional acidified fertilisers, RPR-GYP provides a slow release source of plant-available phosphate, as well as calcium and sulphur needed for plant growth and healthy
    soils.

    All the products used in RPR-GYP are mined in Australia and are of the highest quality, ensuring you get a superior result, whilst supporting a local business.

    General Specifications 80/20:
    • Total P – 7.2%
    • Calcium – 22.3%
    • Sulphur – 4.5%

    We can do any blend ratio and also add in elemental sulphur to increase the dissolution of the RPR and the sulphur content.

    DPI NSW Research in 2006

    In conventional broad acre agriculture, plant available soil phosphorous (P) is usually maintained with P fertiliser like superphosphate. In similar organic agricultural systems such fertilisers are unacceptable inputs so P is often deficient for crop and pasture production on organic farms. A survey of organic farms in south-eastern Australia in 2005 reported available soil phosphate (Olsen P) levels that were frequently less than 6mgP/kg which indicated deficiencies. Improved P management, including developing a fertiliser that would suit organic farming regulations, is required to sustain and increase production on these farms. Reactive rock phosphate (RPR) and elemental sulphur (S) are natural products, suitable for organic use.

    Field and pot experiments were done to measure the impact of ground RPR and co-treatment of RPR with finely ground S, on available soil phosphate, plant dry matter and P concentration. Under dryland farming conditions in this region of southern Australia (<600 mm rainfall, soil organic carbon <3%), co-treatment of RPR with S was necessary to increase Olsen P. The higher values of Olsen P were generally associated with increased plant dry matter, together with higher P concentration in the dry matter. The amount of S required was less the more acidic the soil, but greater than that reported as being effective in higher rainfall situations (>1000 mm) and higher soil organic carbon (11%).

    It was deduced that the S is probably required to overcome the constraint on the dissolution of RPR resulting from frequent periods of low soil moisture. It was concluded that for the south-eastern cropping zone, co-treatment of ground-reactive rock phosphate with finely ground elemental S at rations (RPR:S) of at least 2:1, depending on soil pH, is required for effective use of RPR even in strongly acidic soils. It was recommended that organic farmers may recover soil P fertility by applying RPR+ fertiliser to their most acidic paddocks, postponing soil liming and managing the paddocks to conserve soil moisture.
