Biophos P28 is a fertilizer allowed in Organic Farming, based on natural soft superphosphate. It's extracted by fossilized marine deposits, mainly composed of: corals, bird guano, fish remains, algae and other minerals, with a high content of Phosphorus, Calcium, Magnesium, Silicon and microelements, without chemicals addition.

The product is then finely grounded up to 90% of the particles over 200 mesh, increasing contact surface with roots and increasing the availability of the elements composing it.

Thanks to this method a homogeneous granular product is obtained; the product is well balanced in its composition, rich in important nutritive elements such as Phosphorus (28-29% P2O5), Calcium (38-40% CaO), Silicon (9-10% SiO2), Magnesium (3-4% MgO), Aluminum (1% Al), Potassium (1% K2O), Iron (1% Fe2O3) and other microelements such as Copper, Manganese and Zinc, a formulation quickly absorbed by roots.

Biophos P28 is a fertilizer in light granules with a smooth and uniform surface, powders free, hygienically safe, usable both in Organic and Integrated Agriculture.
