Vermicompost Organic Liquid Extract

General Details

Worm Power Turf is a vermicompost extract produced in an environment tightly controlled from end to end. Worm Power Turf strengthens the physical and biological aspects of the soil around a plant’s root zone. CDFA certified, Worm Power Turf improves soil health, and the health, vigor and strength of your plants.

Consistent and Proven. Worm Power Turf has been awarded 17 peer reviewed research grants from State and Federal Agricultural Agencies and 10 years and 3 million dollars in research has demonstrated Worm Power Turf produces stronger, healthier and more vigorous plants.

  • Enhanced availability of plant nutrients
  • Increases water holding capacity of the soil, reducing irrigation frequency and increasing stress tolerance during harsh conditions
  • Makes nutrient delivery more efficient over an extended period
  • Delivers robust and diverse microbial populations
  • Accelerates root initiation, establishment and development

Lawn and Sport Turf: Apply 16 ounces per 1,000 ft2 (50 l/ha) every 30 days throughout the growing season.



Worm Power Turf Research

To determine the effects of Worm Power on turfgrass health and rooting; and analysis of the microbial content in Worm Power

Evaluation Time Frame:
Summer of 2016

North Carolina State University

Four field trials were conducted to determine the effects of Worm Power on turfgrass health and rooting.  For the creeping bentgrass plant health trial, an ‘A-1’ creeping bentgrass putting green mowed at 0.135 inches was used. For the bermudagrass plant health trial, a ‘Champion’ ultradwarf bermudagrass putting green mowed at 0.135 inches was used.  Plots were rated for turfgrass quality (TQ) on a 1-9 scale (1= dirt, 6= acceptable and 9=perfect), NDVI (Normalized Difference Vegetation Index) and disease severity (DS) (when disease developed) every two weeks throughout the summer months. 

Analysis of microbial content of Worm Power, aliquots of the material were diluted into sterile water.  Dilutions ranged from concentrated product to a 106 dilution.  The various dilutions were plated on to four different media that allows for quantification of general bacteria, fungi, actinomycetes and florescent pseudomonads.  Colonies were counted 48 and 96 hours after plating to determine counts of the organisms listed above.

In the two health studies it was very interesting that the Worm Power treatments showed significantly higher NDVI readings, especially in the creeping bentgrass study.  NDVI is used as another measure of turfgrass quality and in our experience we have never seen NDVI separate out this well before.  Therefore a higher number would equal a plant that is more tolerant of stress.

The plating experiment demonstrates that WormPower has enough microbial material in it to have an effect in turfgrass systems.  Turfgrass systems typically have 107or 108 bacterial cells in soil and 105 fungal cells in soil. Therefore Worm Power actually is competitive when making these applications, but based on the microbial status of each site the product may take a year or two before desirable results are observed.

Table 1. Enumeration of microbial organisms in Worm Power using a spread plate dilution method. Data presented is the estimated number of colonies of each microbial group based on counts from each dilution performed. The limitation here is only those organisms that will grow in culture are counted. Presumably there could be many more that cannot be cultured.
