    Soil health is impaired both by poor cultivation/rotation practices and overuse of input factors such as; fertilisers, fungicides, nematicides and insecticides. 

    Consortium-AL contains a unique combination of especially selected, synergistic species and strains of soil-derived bacteria (as active spores) and fungi to improve soil health, crop vigour and root development.

    Consortium-AL also contains a mixture of fermented High-Carbon Biomass extract rich in amino acids, humic and fulvic compounds. These compounds have been specifically developed to feed and stimulate the growth of the beneficial microbial colonies found in OptiYield microbial mixtures.
