Fibrophos also includes significant quantities of Sulphur, Magnesium, Calcium, Sodium and a range of essential trace elements required by crops and grassland to achieve high yields.
As Fibrophos is produced from the incineration of manure from cereal fed poultry, the nutrients are in a ratio similar to that removed by the crop, therefore making Fibrophos an excellent choice building a stable and balanced level of nutrients within the soil.
Fibrophos is available in a range of grades to suit various situations. All grades contain the full range of secondary and trace elements:
Repeated independent trials of Fibrophos have shown it to be as effective at maintaining PK indices as TSP and MOP.
An extremely cost effective source of P&K against both blends and straights even before considering the ‘free’ secondary and trace elements included.
