WORMCAST ULTRA Boost – 500mL Liquid Worm Fertiliser


WORMCAST ULTRA Boost – 500mL Liquid Worm Fertiliser



Size: 500mL

WORMCAST ULTRA Boost is a concentrated organic liquid worm fertiliser extracted from the vermicomposting process.

The key to this unique and premium concentrate is the worm’s food source, which contains a nutrient blend of organic plant and ocean sources, with crushed minerals, seaweed, fish, lime, rock phosphate, and other natural nutrients. All of this is ultimately broken down and excreted by the composting worms as an enriched and powerful fertiliser.

  • Improved soil structure
  • Increased water retention
  • Stronger plant growth
  • Higher crop quality & yields

Microbe Concentrations

Contained within WORMCAST ULTRA fertiliser is an abundance of beneficial microbes including:

Fungi – helps plant roots to expand, increases the efficiency of nutrient uptake and decreases water requirements on the plant.
Bacteria – consumes organic matter and materials broken down by decomposing fungi with the soil, helping with nutrient cycling.
Protozoa – converts nutrients from bacteria and fungi into a form usable by plants and delivering this close to the plant’s roots.
Beneficial Nematodes – help fight off and consume harmful predatory nematodes within the soil, together with enhancing the soil’s ecosystem and nutrient availability for the plant.


Due to the ability of microbes to increase nutrient availability within the soil the technical analysis of this product may be significantly lower than the actual nutrient availability (actual results being better) when the product is used and microbes are activated and develop within the soil.
