Growing Solutions President Michael Alms reports in from Austin, TX

“The Soil and Water Connection, the 20th Annual US Composting Council Conference theme, certainly brought Compost Tea to mind as a cost effective tool to support water holding capacity in soil,” Growing Solutions President and USCC member Michael Alms commented  while in Austin, TX. (We’ll go deeper into the subject of water holding capacity and Compost Tea in future posts.)

In other Council news, new Executive Director Michael Virga gave an excellent plenary speech outlining many new directions for USCC. Virga announced the relocation of USCC headquarters to Bethesda, MD in April 2012, allowing a more strategic proximity to Capitol Hill and key decision makers that will lift compost awareness on a national level.

“Presenters and attendees discussed establishing vermicompost as a distinct and viable new frontier,” Michael noted as the conference ended. ”Growing Solutions is looking forward to new projects implementing the use of vermicompost and Compost Tea throughout Mexico in 2012 with a new strategic partnership,” he added.

“Our continued participation in Compost Tea research was evident in a compelling presentation by Dr. Fatih Büyüksönmez, Associate Professor at San Diego State University,” Michael explained. He is researching the use of Compost Tea for bioremediation of contaminated soils, utilizing a Growing Solutions System10 and Compost Tea Catalyst. With the help of a graduate student, Dr. Büyüksönmez intends to provide further details of the research at next year’s USCC annual meeting in Orlando, FL. More details forthcoming on this subject in future posts.

Chronicling more than two decades of growth and changes in earthworm composting technology, Clive A. Edwards, Norman Q. Arancon and Rhonda L. Sherman co-edited  Vermiculture Technology: Earthworms, Organic Wastes, and Environmental Management, a 623-page international, comprehensive, and definitive work on how earthworms and microorganisms interact to break down organic wastes on a commercial basis. Published by CRC Press, the book includes research from scientists around the world, exploring the dramatic growth and change in vermiculture technology since 1988.

The use of vermicompost tea is detailed in Chapter 11, The Production of Vermicompost Aqueous Solutions or Teas, written by Cindy Salter and Dr. Edwards. Cindy, a long-time advocate of composting and compost tea, has worked with Growing Solutions and is currently with Seeds of Change at its Oregon production farm. Growing Solutions’ Compost Tea Systems using Fine Bubble Diffusion technology are shown in the book as an example of aerated compost tea production. Cindy’s contribution to the book is in part due to her work with Mary Appelhof, to whom the book is dedicated. Cindy recalled, “Mary was partly responsible for my introduction to compost tea in 1999. She inspired many of us to dig into this field and share her enthusiasm for worms and their ‘micro-brethren.’”

Seeds of Change Director of Seed Production Joel Reiten has wormed his way through all 623 pages, and declared the book an enjoyable read. “This is the most comprehensive, first of its kind compilation of real science with tremendous value for the growing vermicompost and vermicompost tea industry. Commercial growers are eager for this kind of data in order to justify incorporating vermicompost and vermicompost tea into their acreages,” Joel explained.

Vermicompost Technology is available through CRC Press in hardcover and eBook, and in hardcover at amazon.com.

Compost tea brewed on site with Sonoma Valley Worm Farm's vermicompost was a popular item at the conference. More than 80 quarts were given away to master gardeners.

Growing Solutions and Sonoma Valley Worm Farm teamed up to bring the full systems approach—pre-composting, vermicomposting and compost tea—to the California Master Gardeners Conference this week in Santa Rosa, CA. The sold out event brought 500 master gardeners from 43 California counties to learn “More Lessons in Sustainability,” the focus of the four days of presentations and exhibits. Both companies brought their professionally engineered equipment designed for performance and safety to an extremely enthusiastic crowd, eager to learn more about compost tea. SVWF featured their pre-composting bins and GSI displayed the System10, the clear tank System10, and a working System25. The companies gave away more than 80 quarts of premium vermicompost tea brewed during the conference using SVWF’s vermicompost in the System25. Growing Solutions President Michael Alms reported, “Everyone was very receptive to how the SVWF Vermicompost and GSI Compost Tea systems go together, and how the overall process integrates with their mission as master gardeners.”

Michael Alms presents an overview of the compost tea industry at the Hilo workshop.

Sold out! Two words we usually hear from garden centers offering compost tea as the growing season heats up…but this time it was a sell out crowd at a full day workshop in Hilo, HI, organized by the Hawaii Organic Farmers Association and funded by the University of Hawaii. The more than 80 in attendance soaked up the latest research and innovative uses of compost, vermicompost and compost tea during presentations and field trips over the course of the day. Presenters included Dr. Norman Arancon (Sustainable Agriculture Program, CAFNRM), Dr. Ted Radovich (Sustainable Farming Systems Laboratory, UH-CTAHR) and Growing Solutions’ Michael Alms. The afternoon included an on site compost tea demonstration in a commercial vegetable operation at Island Harvest Organics in Pahoa. Michael offered an overview of the 15-year-old compost tea industry, and a look to the future in tropical environments and elsewhere.

Compost tea is applied to pak choi at various stages of growth, part of the SARE grant project led by Dr. Ted Radovich.

Hawaii is leading the world in researching compost tea and its use in tropical and subtropical production systems. The University of Hawaii has a dedicated department for organic and sustainable agriculture, with Dr. Radovich and Dr. Arancon leading the efforts. Dr. Radovich discussed the current SARE (Sustainable Agriculture & Research Education) grant project using compost tea on pak choi. Growing Solutions is participating in this project to further a better understanding of the use of compost tea in on-farm trials and through educational activities, including the May 6 Hilo event.

Dr. Arancon is co-editor of the latest and most comprehensive text discussing compost and compost tea, Vermiculture Technology: Earthworms, Organic Wastes, and Environmental Management. Stay tuned for a post about this culmination of work from an international cast of scientists. Dr. Arancon and Dr. Radovich both work with Compost Tea System10s in their research efforts at UH/Hilo.

Our time spent at the US Composting Council‘s Conference and Trade Show in San Jose has come to a resoundingly successful conclusion. Growing Solutions President Michael Alms and Director of Logistics and Client Services Susan Kelly Mitchell met with conference attendees from all over the United States, and Australia, South Africa, Puerto Rico, Haiti, Nigeria, Canada, Chile, Columbia, Egypt and Brazil. More than 1,100 people attended the 2011 conference, the largest turnout in the Council’s history. Growing Solutions partnered with Sonoma Valley Worm Farm in a large exhibit that featured new product introductions from both companies.

Plenty of interest at our USCC booth where we debuted our newest product, the Solar PV System150.

The GSI booth featured our new Solar PV System150, designed to provide sun-powered electricity to our Compost Tea System25 for a complete 24-hour production cycle. Besides powering the System25, this photovoltaic system can supply power to a wide range of off-grid applications. More information will be available soon on our website.

SVWF introduced a new aerated composting system that was well received at the show. Cristy Christie of the SLO County Worm Farm made our return trip a bit lighter after she purchased our System25 along with one of SVWF’s new composting systems. We were happy to deliver them to her door in Paso Robles. Cristy makes Black Diamond Vermicompost which she’ll be using to make compost tea in her new System25.

Sharon Tamanaha puts the preschool's System10 to work.

Growing Solutions’ distributor Mindy Jaffe of Waikiki Worm Company reports on a great story of a process that we hope to see replicated in schools everywhere. It recalls the sagely adage of “it takes a village…”— in this case, a generous donor supplying a System10 to the Calvary-by-the-Sea Montessori Preschool in Aina Haina, Oahu, Hawaii, where organic waste fed to the school’s worm colony is fully recycled to everyone’s benefit.

Assistant teacher Sharon Tamanaha worked with Waikiki Worm to create the vermicompost program. Not only is the school’s garden and landscape benefiting from the weekly compost tea production, the fourth Sunday of every month is dedicated to tea brewed for sale to church members—always a sell out—that brings revenue to help sustain the program.

“We are very, very happy with our brewer,” Sharon says. “It’s easy to use and clean. Every plant is healthy and robust and the entire property just glows.”
