How to Use Worm Castings
Soil Ammendment
Worm castings can be used as a soil amendment at 250 to 300kg per Ha. Add with your lime, gypsum or mineral applications. Adding castings to nutrients allows you to use less minerals due to the microbes making them more readily available to the plants.
Extract
Use worm castings at 70kg per 1000L to make an extract. Apply the extract at 50 to 70L per Ha (as your water source) with 5L of concentrated NutriSoil liquid. The 3mm converts to 76.s microns. When applying the extract, keep the pressure 50psi or lower.
Tow and Fert Machine
The 3mm castings can be added directly to your Tow and Fert machine at 70kg per 1000L of liquid and applied at 50 to 70 litres per Ha. Apply the concentrated Nutrisoil liquid at 5L per Ha. The castings and the liquid are complementary in microbes. Most natural products can be added with the liquid and worm casts including fish and molasses. If adding nutrients with the castings or Nutrisoil, add last and do not leave tank mixed for more than 16 hours. When applying the castings, keep the pressure 50psi or lower.
Worm Castings: High Microbial Diversity and Biomass
Worm Castings are distinguished by their high microbial biomass and diverse microorganisms in their solid form. This makes them highly beneficial as a soil amendment, enhancing soil health over time.
Nutrisoil Biological Solution: Fast-Acting and Direct Application
In contrast, the NutriSoil Biological Solution offers a more immediate impact. Its formulation allows for direct application to plant leaves and seeds, providing swift and effective nourishment of secondary metabolites, microbes and nutrients. The higher concentration is due to the amount of times the liquid is misted through the castings and the high mass of castings used in the production process.
Worm Castings Extract:
An extract made with 70kg of worm castings and 1000l of water (aerated and stirred for two hours) is lower in microbial biomass, diversity and nutrients, however the microbial diversity is different to the diversity of the Nutrisoil Biological Solution due to the aeration of the product and the lower concentration of worm castings used in the process.
Both the NutriSoil Biological Solution and Worm Casting Extract possess unique microbial profiles, with varying types and quantities of microbes. This diversity is the cornerstone of their synergistic effect. Use the Nutrisoil Biological Solution at 5L per Ha with the Worm Castings Extract at 10 to 70L per Ha. Adding nutrients to this mix prior to application will enhance the uptake of the nutrients.

DNA Testing of NutriSoil Biological Solution Vs 70kg Extract (In 1000L of water)
*DNA testing shows percentage of microbes in a sample, not abundance.
While DNA testing is arguably the most accurate testing we have in microbial testing to date. In the category of species, it still only tells us 30% of what is known. The other 70% is either unculturable or not yet identified. When interpreting DNA there is a taxonomic hierarchy which categorises organisms into categories. There are seven major taxons that organisms are classified.

Species
The Phylum/Division group is a very broad range. Phylum is used for animals and division is used for plants. Below is the taxonomic hierarchy of a human. The Phylum Chordata include all animals that possess a notochord at least at one point in their lifetime. Amphibians, reptiles, mammals and animals are all part of this group.

SPECIES
Below are the highest 5 percentage rates of species in each product.
You can see that the microbial species are different in the Nutrisoil Biological Solution compared to the Worm Extract which creates the synergistic effect that both products have together.
The NutriSoil Biological Solution is higher in the amount of species and has a more diverse abundance range indicating a more balanced microbial community.
• Nutrisoil Biological Solution has been tested alongside other composts and extracts that are non worm based. The percentage of unknown in a worm liquid highlights the complexity of what comes from a worm.
