Guano Gold Split P Range

Guano Gold Split P Range

Extract more value from your Phosphate dollars

By integrating Guano Sulphur Gold-Split P and the newly developed and formulated Guano Liquid Gold-Split P into your farming program you can drive your Phosphate further.

Phosphorous analysis is extracted in a test tube; however, the soil is anything but a test tube environment. The Phosphorous in our 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 Phosphorous [P] in the Guano Gold-Split Pfertiliser range combines with natural Calcium, Gypsum, Silica and trace elements giving your crop the perfect start from germination to maturity.

The Guano Sulphur Gold-Split P is a prilled product; tested and suitable for use in air seeders, combines and planters whilst the Guano Gold-Split P-Kwik Start is a granular for ground spreading throwing the same as single super through a belt spreader.

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 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 Phosphorous 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 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 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 Guano Sulphur Gold-Split P at sowing down the tube or 100 kg of 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.
