BIO PHOS

• RELEASES FIXED PHOSPHORUS FROM SOIL
• IMPROVES PHOSPHORUS AVAILABILITY IN SUPER & ROCK PHOSPHATE
• MINIMIZES FERTILIZER REQUIREMENT
By understanding the principles of phosphorus cycling in soil we can plan fertilizer application very effectively. The reactions that make the native and applied soil phosphorus less available for plant uptake are collectively known as "phosphorus fixation". This ultimately results in improved soil fertility and crop yield. No matter what fertilizer we add to the soil, whether it is super phosphate (0-46-0), Di ammonium phosphate (18-46-0), or Mono ammonium phosphate (11-52-0), the fate of phosphate is ultimately the same. When applied to the soil, the phosphate in each of these products is fixed and becomes non available to crops.
In acid soils (pH < 6.5) phosphorus is fixed mainly by aluminum and iron. In basic (alkaline) soils (pH > 7.2) phosphorus is fixed mainly by calcium. Our soils tend to be acidic, so fixation by Al & Fe is dominant. It is estimated that as much as 90% of added fertilizer phosphorus is fixed in acid soils.
“Bio Phos” can be mixed with rock phosphate @ one liter per tonne. Upon mixing, this beneficial bacterium multiplies in multifold and subsequently when applied in to soil, it releases P effectively from rock phosphate in a continuous way. The fertilizer use efficiency of rock phosphate is increased several fold due to “Bio Phos”. Under normal condition on an average only 5% of P is made available to crops from rock phosphate. The combined application of “Bio Phos” along with rock phosphate increases the P availability to more than 50%.
We feel proud to “Produce and Introduce this ““Bio Phos”” in our island and the specialty of our approach is the usage of Native Srilankan cultures. This P solubilizing bacterium has been isolated from the soils of our island and screened to select the elite cultures for commercial use. Being children of our soil, the adaptability, multiplication and effectiveness of these native isolates will be very promising.
