EXTRACT MORE VALUE FROM YOUR PHOSPHATE DOLLARS
By integrating Madura Guano Sulphur Gold-Split P and the newly developed and formulated Madura Guano Liquid Gold-Split P into your farming program you can drive your Phosphate further.
Phosphorus analysis is extracted in a test tube; however, the soil is anything but a test tube environment. The Phosphorus in our Madura Guano Gold-Split P Fertiliser range of products is mainly non water soluble giving a "Split P" drip feed effect for crop growth throughout the whole season. The available Phosphorus [P] in the Madura Guano Gold-Split P fertiliser range combines with natural Calcium, Gypsum, Silica and trace elements giving your crop the perfect start from germination to maturity.
The Madura Guano Sulphur Gold-Split P is a prilled product; tested and suitable for use in air seeders, combines and planters whilst the Madura Guano Gold-Split P-Kwik Start is a granular for ground spreading throwing the same as single super through a belt spreader.
Madura Guano Liquid Gold is a full suspension product for use through fertigation, irrigation and foliar boom applications.
So for once and for all, get the full dollar value from your Phosphorous by making the Madura Guano Gold-Split P range of fertiliser products an intricate part of your PMS-FUE.
Guano Australia now offers independent lab testing for Phosphorus Buffing Index [PBI] as a part of its soil testing services.
The long running CSIRO trials have proven that water soluble phosphate from Single Super, MAP or DAP can become ‘tied up’ in the soil. All soils are different in pH, Iron, Manganese, Calcium and Aluminium; all these will affect available Phosphorus [P].
Due to these factors Phosphorus levels in the soil FUE can be very low. CSIRO trials (McBeath 2011) showing that Phosphorus FUE ranged from 3–30%.
This means that out of all the Phosphorus applied to the crop, a maximum of 30% was used. Based on the above CSIRO work, a soil that has a FUE of 30% would require 200 kg/ha of DAP while a soil with FUE 80% would require 75 kg/ha to deliver 12 kg/ha of usable Phosphorous.
Therefore, the real cost of the effective Phosphorus is dramatically affected by the soil characteristics as calculated in the FUE. Soils with low FUE tend to only receive about 6 weeks of Phosphorous from the fertiliser then must rely on soil mineralization to extract Phosphorus from the soil.
Adding to the above CSIRO trials (McBeath 2011), Professor Gleeson confirms, Australian grain producers apply $1 billion worth of Phosphorus [P] fertilisers each year, but only 50% is taken up by plants. Much of the remaining fertiliser P becomes fixed in soil and the P ‘bank’ in Australian arable soils is estimated to be worth $10 billion. She goes on to say; improve understanding of the mechanistic basis of rhizosphere strategies for enhancing Phosphorus mobilisation in order to optimise Phosphorus use within farming systems.
In a conventional farming system the Madura Guano Gold-Split P range of fertiliser products can be blended with MAP, DAP or SSP to obtain both water soluble Phosphorus and citric and noncitric Phosphorus.
On soil tests the FUE has been reworked as the PBI. This Index takes the FUE and converts it into a 0 to 1000 scale with the higher the number the higher the risk of Phosphorus [P] tie up. In general once the PBI goes above 150 then tie up starts to affect P up take.
36-70 = Very Low
71-140 = Low
141-280 = Medium
280-840 = High
840> = Very High
An example would be in a soil with a PBI of 400 and an average P soil reading would require 30 kg per hectare of DAP mixed with 60 kg of Madura Guano Sulphur Gold-Split P. This would give 6 kg of P per hectare for early growth and 6 kg of P per hectare of drip feed P to sustain the crop. This would be enough P for a 4t/Ha crop.
In an organic system 120 kg of Madura Guano Sulphur Gold-Split P at sowing down the tube or 100 kg of Madura Guano Gold-Split P-Kwik Start could be broadcast would give enough P for a 4t/ha wheat crop.
It can be concluded that finding out the soils FBI based on the FUE, is the first step in an Integrated Phosphorous Plan to calculate your real cost of effective Phosphorus.
Madura Guano Gold has been tested and proven by the independent Food and Agriculture Laboratories Australia Pty Ltd [FALA] which proves
Madura Guano Gold is the only known Guano Product in the world that has this unique 80/20 "P Split"
Hence, phosphorus is available for the whole growing cycle. This is now further proven by our Madura Guano Gold-Split P graph test as conducted by SWEP Laboratories which evidences the way the phosphorus is released in soil as a steady line over time.
The citrate insoluble components of Madura Guano Gold fertilisers contain Phosphorus [P], which is insoluble in water as well as in citric acids at 2% solution. The P rate of release is governed by soil temperature, soil biology and root exudates or soil organic matter.
Is it any wonder how and why Guano Gold gives Australian agriculture a "Kwik Start"
