Volume 1-10 ebook

Casting Call is VermiCo’s bi-monthly newsletter was published 6 times a year for 10 years, keeping readers up-to-date with the latest developments in vermiculture. Every 60 days we brought you the biggest stories, events, book reviews, interviews with industry leaders, and news items to keep you informed. Our primary focus is upon vermiculture, composting, soil fertility and related issues of organic waste.

Some highlights of past issues:

Pathogens Removed Through Vermistabilization: “[Dan] Holcombe reported that tests performed on worm-worked material originating as bio-solids waste showed ‘no detect’ on such pathogens as E. coli and Salmonella as well as some enteric viruses. Not only is this report significant, but the process of vermistabilization (as Holcombe refers to it) means that vermicompost does not become inoculated with harmful airborne bacteria when exposed to unprocessed waste in close proximity.” Casting Call, Vol. 1, No. 2

“Compost Tea” vs. Miraclegro: “Results of the plant growth trials showed the compost tea outperformed both the commercial fertilizer and water only on both types of plants, The 1:1 dilution of runoff [compost tea] with water produced the best results with marigolds showing increased flower and bud production. Root growth on the radishes was seven times larger than on the control (water only) plants.” Casting Call, Vol. 1, No. 3

Rock Dust & Re-Mineralization: “Adding the [rock] dust to compost can accelerate the process of plant assimilation as the activity of soil microorganisms enchances the breakdown of mineral particles.” Casting Call, Vol. 1, No. 4

Interview with Mary Appelhof, Author of Worms Eat My Garbage: ” [Q] Several notable vermiculturists have credited you with being a pioneer in the field. How does the ‘worm climate’ today differ from the days in which you were first starting out? [A] The interest now is just growing–more and more people are doing it. It’s definitely changed, not only in my life, but now there are large-scale projects….At the time that I started I don’t believe there was an industry. I believe there is a developing industry now….” Casting Call, Vol. 1, No. 5.

West Coast Vermicomposting Operations: Low to High Tech Systems: “One of the trends now forming, particularly on the West Coast, and one that is sure to develop in the future, is that of joint ventures between vermiculturists and existing composting operations. Some facilities, successful in thermophilic composting, are considering the addition of vermicomposting to their methodologies in order to increase their product sales.” Casting Call, Vol. 1, No. 6.

Interview with Barry Meijer, Pacific Southwest Farms, Ontario, CA: “So initially we were taking in about 75 tons per day (now we’re up to 100 tpd). If we were now where we would like to be, we would be receiving about 300 tons per day. We started with 11 rows of worms with the staff from my landscape company spending a couple days a week out here….Our plans for expansion include a 120-acre site in Bakersfield and tow other 50-acre sites.” Casting Call, Vol. 2, No. 1.

Interview with Jim Jensen, Yelm Earthworm & Casting Farm, WA: “We suspect and our customers believe that there are growth enhancing properties that aren’t necessarily found in compost–that the worm itself adds something to this that is vital–that’s why they’re on the earth–they add value to soil. We should know more about what that value is and the economic value of it.” Casting Call, Vol. 2, No. 2.

Interview with Al Eggen, Original Vermitech Systems, Ltd, Toronto, Canada: “We’ve been working with a large steel corporation to do manufacturing, a a consulting company to build Vermi-Digesters. Pilot projects are proposed for a college and another Canadian Pacific Hotel in Halifax. The proposal speaks of a $12 million market manufacturing approximately 275 Vermi-Digesters at a cost of $43,000 each. The target is to process 16,500 tons of material which represents about 10% of the organic waste stream. We’re looking at starting this in about 6 months or less.” Casting Call, Vol. 2, No. 3.

Interview with Larry Martin, Vermitechnology Unlimited, Inc., Orange Lake, Florida: “From the market research I’ve done, with $250,000 in start-up costs, with one full-time and 2 to 3 part-time people, you could produce about ten tons of castings per week. The first year’s projected income is about $15,000 per week for the first year’s spring and fall marketing. Within 3 years, still in just the greater Orlando area, you could generate about $250,000 a month in sales.” Casting Call, Vol. 2, No. 4.
