Bio NPK™


Soil Inoculant

Fruit & Vegetables

Bio-NPK™ is a biological fertiliser for improving the nitrogen, phosphorus and potassium nutrition of plants.

It contains Azotobacter vinelandiia and two strains of Bacillus megaterium bacteria that fixes nitrogen, releases phosphorus from soil reserves and mobilises potassium in the soil. This combination of bacteria secrete bioactive substances that stimulate the growth and development of plants with long term use leading to improved soil structure.
