Guano Organic Fertilizer News

The seven-in-one mega blend

The majority of soils have the capacity to “fix” large amounts of Phosphorus. It’s not uncommon for 20% of soils to give you 80% of your problems – but there is a solution!

Fixation occurs as a result of Phosphorus being converted in the soil into chemical states that are less available to plants.

Guano’s range of blended fertilisers contain Phosphorus in water and non-water soluble forms as well as Ammonium Sulphate and Silica. These unique blends are targeted at soils which are prone to Phosphorus tie up.


  • Do I have elevated levels of Calcium, Manganese, Aluminium or Iron?
  • Do my soils have rising levels of Sodium?
  • Do my soils have Sulphur deficiency?
  • Am I applying or have I applied lime, gypsum or dolomite?

If you answered yes to one or more of the above questions, then a custom blend containing silica and non-water soluble Phosphorus may be an agronomic option.

Custom blend fertilizer utilising seabird guano provides considerable benefits.


The blends contain Potassium, Sulphur, Magnesium (KMS), Ammonium Sulphate (AmSul), Guano Gold and/or MAP or DAP in a blend of your choice.


Some soils are prone to phosphorus binding with other elements that then form compounds that are no longer plant-available. In these soils, using traditional water-soluble Phosphorus fertilizers can be inefficient.

By blending Phosphorus-type fertilisers and adding Silica these new blends drip feed ‘P’ into the soil system while the presence of Silica protects the soluble ‘P’ by binding with Fe, Al, Mn or Ca and thus allows the ‘P’ to be plant available.

Custom blends are available across Australia. For all your custom blend needs, contact Guano Australia today.

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
