PBSA
the ultimate designer fertiliser
In its standard format, PBSA is a sterile, organic slow release fertiliser with a Nitrogen, Phosphorus and Potassium (NPK) value of 5.4-6.6-4.2. It is pH neutral. It has a water absorbing capacity of 20 times its own mass and has substrate binding properties.
Because it is a cross linked polymer granule it has the ability to hold any number of additional ingredients required for different crops or substrates. The NPK values can be enhanced, the super absorbent ratio can be increased and acid or alkaline can be added to alter its pH value.
PBSA has financial, environmental and agricultural benefits, click here to read more
