Worm Casting Fertiliser Benefits

Wormco Organic Fertiliser Information

Maximises nutrient availability

Our range of products are produced from microbe, enzyme and nutrient-rich worm castings and are combined with a natural microbe food-source to create this unique, high performing organic fertiliser. The biological mix of beneficial soil microbes and humus help to increase the soil’s nutrient availability and regulate the plant’s nutrient uptake, stimulating stronger root and foliage growth.

Improves soil structure

The biological mix of microbes, together with the increased humus mass help to improve the soils overall structure, nutrient levels, and water holding capacity, as well as increase soil aeration and oxygen availability. The soil structure also benefits from reduced surface water run-off, soil erosion and increases buffering properties of soil.

Increases yields and quality

Capitalising on the ongoing growth of the soil’s improved ecosystem, its enhanced structure and the improved availability of nutrients, minerals, water and oxygen from within the soil, the plant is supported during all of the various stages of the plant’s growth. This ongoing delivery of nutrients and an overall better soil environment results in increased yield levels and crop quality.

Disease suppression

Minimises the need for disease controlling chemicals due to both a stronger plant being grown, that can suppress disease-causing organisms and the actinomycetes found in worm castings that naturally kill parasitic fungi such as Pythium and Fusarium.

Contains humic acid

Humic acids, a humic substance that forms a major component of humus, enhances nutrient uptake of plants by increasing root formation and elongation, as well as increasing the permeability of root cell membrane, stimulating root growth and increasing proliferation of ‘root hairs’. Humic acid also improves soil nutrient holding capacity, water holding capacity and aids in both the soil’s and plant’s ability to absorb energy from the sun.


The story behind this extremely powerful natural fertiliser originates from vermicast, or the nutrient and microorganism-rich castings produced from worms through a process called vermicomposting.

Compositing worm varieties are an ecosystem engineer in that they convert environmental waste into a powerful organic fertiliser. In this process the worms are added to their favourite food-source in the form of organic matter and waste where they consume this material, breaking it down to a micro level, then excrete. This results in a fertiliser significantly richer in NKP (nitrates, phosphates and potash) than other forms of manure and compost but it also boasts heightened levels of other key nutrients, microbes and colloidal humus.

Microbe concentrations

Contained within Worm Hit 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.
