100% Natural Organic Phosphorus FertiliZer & Soil Conditioner

Environmentally-friendly and certified for use in both organic and biodynamic farming, Madura Guano Sulphur Gold® granulated airseeder friendly fertiliser is one of the best farming fertilisers for sustainable and productive cropping. It contains 4 elements that are essential for your cereal, cotton, pulse, pasture programmes and more.

12.6% Phosphorus is provided in 90% citric and 10% non-citric form providing a drip feed supply of Phosphorus throughout the growing season. The Phosphorus in the granule is in the form of a Di Calcium Phosphate and when this reacts with weak solutions of acid in the soil, soluble phosphate and calcium are released and these nutrients become available for plant uptake. To aid this process, at planting the naturally occurring silica in the granule reacts with water to form mono silica acid which in turn assists with the breakdown of the Di Calcium Phosphate. The non-citric soluble Phosphorus becomes available at higher concentrations of acidity in the root zone and, this acidity produced in part by root exudates in the maturing plant.

11% Elemental Sulphur in the elemental form and mineralises to provide a slow release of Sulphur for the entire growing season without leaching or being lost to the atmosphere as a gas. Sulphur allows the plant to efficiently uptake nitrogen and in legumes allows nitrogen fixation. Apart from supplying nutrients directly to the plant elemental Sulphur, by conversion in the soil, to Sulphuric Acid reacts with the naturally occurring Calcium Carbonate to produce plant available Calcium. This Calcium can then be used by the plant and or to assist in displacing Sodium, for this Sodium can then be leached from the soil.

24.8% Silica in the form of a mono Silica Acid is taken up by the plant with water uptake and is deposited in the cell walls. This gives the plant a considerable increase in stem strength while providing a mechanical barrier to both fungal infection and water loss. Like Sulphur, Silica has a function in the soil chemistry as well as the plant. Free Silica in the soil will displace Phosphorus that is bound to Iron liberating plant available Phosphorous while producing an Iron Silicate.

26.2% Calcium in the form of Di Calcium Phosphate. The organic fertilizer's Calcium benefits are taken into the plant with water. Calcium is necessary for cell development. Research shows Calcium uptake begins 5 days after seed hydration therefore available Calcium at the seed is essential. Without good calcium levels, plants cannot use Nitrogen efficiently.

Madura Guano Sulphur Gold is a granulated, airseeder-friendly 100% organic fertiliser.

Being so far away from our markets, durability is critical and the Silica is really good in terms of hardening up the skin and making the melons better to transport.Ord River WA irrigator David Menzel-Barradale
The problem with many organic fertilisers is that they have very low rates of nutrients, meaning you need to put out high rates. A product like Guano Gold has 12pc P, whereas Guano Sulphur Gold has 10.5pc P, obviously with additional sulphur. These figures compare very favourably with something like a single superphosphate product. Agronomically, it’s a good product in any setting, not just for organic producers.Garry Allison, Landmark Agronomist. Mount Gambier, SA
For the broadacre croppers, Guano Gold works really well in paddocks where they have had issues with nutrient tie-up. He said the majority of synthetic P products have large rates of water soluble P. The problem with that is that you can have instances where it ends up tying up zinc in the soil so you run into problems with zinc deficiencies. Not only does the slow release nature of the Guano Gold product work well over the entire season, it also contains zinc for the crop as well as the other nutrients.Moree agronomist Rob Drewitt
We strongly recommend the Guano Gold products to fellow farmers if they are looking at improving their Calcium and Silica levels using various methods of application such as foliar and granular.James and Aimee Thomas Falkirk Macadamia Farm
I have recommended Guano Gold products for 20 years and in all cases had excellent long-term results increasing in pasture productivity.Paul Baguely - PB Ag Consulting
They are high analysis products so you get your nutrients without having to put too much fertiliser out.Anthony Beutel, Googa Farm Organics
We have known since the 1930s that phosphorus is one of the main elements required to grow a successful crop of not just the (flax) plant but the seed. It was one of those products that was first out in a granular type form and it was so much easier to get an even coverage over the ground, rather than a powder form. Later on the product became a little more refined, so we could put it through our air-seeder. We also broadcast some of it, prior to seeding, when we are cultivating ground. The products have great characteristics in relation to phosphate and silica, which is exactly what we need for flax.Waltanna Farms flax-seed farmer & Ambassador for Guano Australia, Michael Nagorcka
