Dear colleagues,
Positive effects of Liquid Vermicast/vermicompost Extract (LVE) have been studied and published over the past decades, and the results on soil and plant health, yield, crop quality, suppression of diseases and pests, and mitigation of plant stress, to name a few, are overwhelming.
Often the publications describe the process of generating the LVE, the concentration or dilution and the frequency of the application. This information is very beneficial for consulting with farmers and growers, leading to increased requests for vermicast/vermicompost and its extract.
I often find application rates are missing: such as litres/ha or kg/ha or when applied in an orchard. What are the application rates when LVE is used in hydroponic systems?
I have the following question or request:
Can you share information, papers, or studies publishing the application rates in combination with the crop applied to and, if available, the concentration or dilution?
Please share links or uploads in this forum.
You can directly contact me at [email protected]
Kind regards,
Michael Quintern
This is where a small amount of worm castings is placed in a 5 gallon bucket of water and aerated with an air pump (or even by hand). Liquid vermicompost extracts (LVE), also commonly known as vermicompost leachates or teas, are byproducts obtained during vermicomposting, a non-thermophilic process mediated by earthworms and microorganisms that bio oxidize and stabilize organic matter into usable bio stimulants. Vermicast is a mixture of earthworm castings and uneaten bedding and feedstock harvested from worm beds. This means that we started with organic materials for bedding and added feedstocks. is a nutrient-enriched liquid that drains through worm-beds containing vermicomposted wastes, bedding materials and worm populations Vermicompost stimulates to influence the microbial activity of soil, increases the availability of oxygen, maintains normal soil temperature, increases soil porosity and infiltration of water, improves nutrient content and increases growth, yield and quality of the plant . It is a non-toxic and eco-friendly compound, which inhibits the growth of bacteria and forms a protective layer for their survival and growth. Vermiwash at 5 to 10 per cent dilution inhibits the mycelial growth of pathogenic fungi. It has the ability to combat insects thereby saving the plants and their productivity.

applications of liquid vermicast in agriculture and horticulture are., it helps in improving soil texture, aeration and increases water retention capacity. Vermicompost acts as a soil conditioner and improves the biological, physical and chemical properties of the soil.
The recommended application rates of liquid vermicast extract can vary based on factors like soil type, plant type, and specific product instructions. Generally, for agriculture and horticulture, a dilution of around 1:10 to 1:20 (vermicast extract to water) is often suggested. It's important to follow the instructions provided on the product label or consult with local agricultural experts for precise recommendations tailored to your specific needs.
