Worm Compost Research

Worm compost research on the benefits of worm compost is on-going worldwide. These studies provide important and vital additions to the increasing amount of information we have about worm compost and the many applications it has in and on our world today.

Those applications range from:

  • applying worm compost tea to animal pastures in order to increase grass quality

  • increasing plant health by applying disease-fighting microbes through soil application of worm compost or actively-aerated worm tea

  • getting away from in-organic fertilizers and pesticides and returning to natural, soil-friendly practices of gardening, farming

  • using worms and worm compost tea in soil remediation of toxic waste products.

    Several worm compost research studies are posted here regarding various aspects of scientifically-tested benefits of earthworms and the amazing qualities of their manure.

    Worm Compost Effect on Growth,
    Yield and Quality of Tomato

    This research was undertaken by Rakesh Joshi and Adarsh Pal Vig from Guru Nanak Dev University, Amritsar-143005, Punjab, India

    The worm compost was cow-manure based and the basis in three different soil mixtures:

    1)Soil (control)
    2)VC15 (Soil+15% VC)
    3)VC30 (Soil+30% VC)
    4)VC45 (Soil+45% VC).

    Germination percentage was taken for each mixture. Seedlings were randomly selected from each treatment and put into pots containing the same mixture as in trays.

    Growth and yield markers were noted such as stem diameter, plant height and leaf number among other things.

    The study found that germination was highest with the VC15 mixture.(Highlighting added for emphasis) Almost all the markers increased as compared to the control, though the increase within the three ranges was not significant.

    The smallest concentration of treatment supported the highest germination which backs up my anecdotal observation that a little (15-20%)goes a long way!

    Use of vermicomposts
    in Management of
    Parasitic Nematode Populations

    "Commercial vermicomposts, produced from cattle manure, food and recycled paper wastes, were applied at rates of 5 tons/ha(a hectare=2.5 acres), 10 t/ha and 20 t/ha, to field plots planted with tomatoes (Lycopersicon esculentum) bell peppers (Capsicum anuum grossum), strawberries (Fragaria ananasa) or grapes (Vitis vinifera).

    Control plots were treated with inorganic fertilizers only, and all vermicompost-treated plots were supplemented with inorganic fertilizers, to equalize levels of available nitrogen in all plots.

    Nematode populations were estimated by extraction in funnels and identified and classified to trophic level.

    Populations of plant-parasitic nematodes were lowered significantly by the three vermicomposts in all four field experiments compared with those in plots treated with inorganic fertilizer. (Highlighted for emphasis). Conversely, populations of fungivorous and bacterivorous nematodes tended to increase consistently compared with those in the inorganic fertilizer-treated plots."
