Biocast: liquid vermicast biostimulant

By Island Biologicals

Life Creates Life

Welcome to the home of Biocast! If you’re looking to grow plants that are full of LIFE, from soil to seed, then you’re in the right place.

At Island Biologicals we believe that life creates life. Biocast supports the whole plant, including its microbiome, thanks to the life-stimulating compounds of earthworms and beneficial microbes. As a grower it can support you to add health and vigour to your high production systems, to get plants through stressful times (such at transplant, or climate extremes), or give you a stepping stone to get off the inputs treadmill. It is a high quality, natural biostimulant that you can feel good about applying, and that will be good for you, your family, your customers and your land.

“The health of the soil, plant, animal and man is one and indivisible”

Sir Albert Howard

What is Biocast?

Biocast is a liquid vermicast biostimulant. What that means is that we’ve extracted our high-quality worm poo (cast) into water, and with it all the life-stimulating compounds produced by the worm and associated microbes. These include living microbes (bacteria, fungal spores, and protozoa), growth-stimulating hormones, enzymes, autoinducers (signalling molecules), fulvic acid and trace minerals. These all work together to benefit plants and soil life. Biocast can be applied as a foliar, seed dressing, transplant drench or through fertigation systems.
