Chemically granulated fertilizer [photo] 

Ammonium toxicity damages plant roots and water-conducting (xylem) tissues. As the xylem collapses and roots are damaged, water uptake is restricted and wilting and stunting occur.


With the value of pure phosphorus in fertilizer form at above R30.00/kg and thus the value of one part per million (ppm) thereof in the field at more than R200/ha (excluding return on crop response), the South African farmer needs to be very aware of his choice of phosphorus source.


Omnia is the only company in South Africa that continues to chemically granulate fertilizer and in a unique way.
