What fertiliser is low in phosphorus?
Species that prefer low Phosphorus fertilisers are generally those from the Proteaceae and Mimosoideae families such as Waratahs, Grevilleas, Banksias, Wattles. These plants naturally occur in Phosphorus-impovorished soils and are extremely efficient at utilising the small amounts of available Phosphorus.
Are Australian natives phosphorus sensitive?
Examples of phosphorus sensitive plants include members of the Proteaceae family and some Australian native plants such as Banksia, Grevillea and Hakea species.
Does all fertilizer have phosphorus?
Phosphorus is a component of most fertilizers that helps plants to grow. According to several experts, in most cases phosphorus is not needed to maintain a healthy lawn.
Are Australian soils high in phosphorus?
Most Australian soils are naturally low in phosphorus due to extensive weathering! While native plants are adapted to these low levels, introduced crops and pasture grasses are not, which means that we need to apply phosphorus fertilisers to soil to achieve productive yields.
Is Seasol high in phosphorus?
Yes, because Seasol is virtually phosphorous-free it is safe to use on phosphorous sensitive native plants. You can use it on every type of plant in the garden.
What is the best fertilizer for Australian natives?
The truth is natives don’t like manufactured or chemical based fertilisers that are high in phosphorous. But they do like to be fed, ideally in spring and autumn, either with a specifically designed Australian native plant food or an organic based fertiliser such as blood and bone or pelletised chicken manure.

Is Seasol OK for native plants?
Does Epsom salt have phosphorus?
The nutrient value of Epsom salts is 0-0-0, meaning they contain no traces at all of nitrogen, phosphorus, or potassium. If you do choose to use Epsom salts on your plants, it’s important that you are aware that Epsom salts are not a substitute for fertilizer.
Does Seasol have phosphorus?
What is a natural high phosphorus fertilizer?
Bone meal is an excellent high-phosphorus fertilizer with an average N-P-K ratio of 3-15-0. The phosphorous in bone meal takes a few months to become available to plants via microbial processes in the soil. It also contains calcium, another essential plant nutrient.
What’s the difference between Seasol and PowerFeed?
What is the difference between Seasol and PowerFeed? Seasol is made from two species of seaweed – Bull Kelp (Durvillaea potatorum), Chile Bull Kelp (Durvillaea Antarctica) and Knotted Kelp (Ascophyllum nodosum). PowerFeed is a fertiliser. It has a fish base which is fortified with nitrogen, phosphorus and potassium.
How much phosphorus is used in Western Australia?
Phosphorus (P) is one of the most critical and limiting nutrients in agriculture in Western Australia. Phosphorus cycling in soils is particularly complex, and agronomic advice is recommended when interpreting soil test results. Only 5 – 30 % of phosphorus applied as fertiliser is taken up by the plant in the year of application.
Why are phosphorus fertiliser prices at their lowest?
INTERNATIONAL phosphorus (P) fertiliser prices have hit their lowest values for over a decade in response to increased production and decreased demand.
What kind of fertilizer to use on Australian plants?
There are low-phosphorus fertilizers available (N:P:K composition of about 10:3:6) which can be used on phosphorus-sensitive species. Further information on this topic is available in the article Phosphorus Needs of Australian Plants and this can be used as a guide to fertilizer application.
What’s the price of Di Ammonium Phosphate in Australia?
In spite of a low Australian dollar it means retail prices for mono-ammonium phosphate (MAP) and di-ammonium phosphate (DAP) have dropped to levels in the low to mid $500s a tonne, a quote attractive enough to get farmers interested in ordering new season fertiliser while still completing this year’s harvest.
