TerraVesco – Healthy Soil. Healthy Food. Healthy People.: work hand-in-hand with the genius of nature to feed the soil and grow healthier, more beautiful plants organically and sustainably

iCrowdNewswire - May 5, 2016




Healthy Soil. Healthy Food. Healthy People. These are the cornerstones of TerraVesco.

TerraVesco’s mission is plain and simple: work hand-in-hand with the genius of nature to feed the soil and grow healthier, more beautiful plants organically and sustainably.

There is a strong movement toward an organic, sustainable approach to modern agriculture to meet the challenge of feeding the world’s increasing population without compromising soil, plant, environmental, or human health. At the center of sustainable agriculture is organic soil health.

As more and more growers look to transition away from using chemicals, they must incorporate organic solutions that naturally accelerate soil fertility and biodiversity. TerraVesco’s vermicompost products do just that.  Our unique production process leverages the power of earthworms to create highly consistent biological and sustainable soil amendments that produce healthier, more resilient food and plants.


The conventional, industrial approach to agriculture leads to soil degradation, and requires increasing use of inorganic, chemical inputs to maintain crop yields. There are seven basic farming practices that form the back bone of modern industrial agriculture:

  • Intensive tillage
  • Monoculture
  • Irrigation
  • Application of inorganic fertilizers
  • Chemical pest control
  • Genetic manipulation of domesticated plants

Many of the techniques that have been used to increase productivity have a great many negative consequences that, in the long term, work to undermine the productivity of agricultural land.  Conventional means of increasing productivity will need to be supplemented to help meet the increasing food needs of an expanding global population.

The powerful green, sustainable movement is a primary driver behind the trends currently impacting American agriculture. The higher prices that organic produce command has enabled significant growth in the number of organic farms and local farmers’ markets. A growing number of industrial, conventional farmers are exploring ways to integrate organic practices and crops into their overall product mix to take advantage of better pricing and higher profit margins.

The green, sustainable movement continues to have a significant impact on environmental policy and government regulation of the pollution caused by agriculture. An increasing number of Americans are concerned about their own health and the health of their families. The current epidemics of obesity and diabetes demand greater analysis of the potential causes and a re-evaluation of the approach to modern agriculture and the food delivery system.

All of these factors will continue to increase the demand for alternative, organic soil amendments in various segments of the agricultural industry. Management believes these trends are well entrenched and long lasting, and will continue to offer favorable conditions for the future growth of companies that elevate themselves within the commercial agriculture space by providing science and data-validated solutions and consistent, reliable, high quality products.


TerraVesco produces high quality OMRI listed, CDFA certified organic Vermicompost and Vermi-extract. Both academic and commercial field trials document the efficacy of vermicompost and extract in the delivery of a range of benefits including increased plant development and growth, stronger plant resiliency, enhanced nutrient uptake and improved transplant success. By incorporating TerraVesco Vermicompost and Vermi-extract into soil, nature can do what nature does best: cycle nutrients, nourish plants, and fight disease.

TerraVesco’s Vermicompost is produced through a continuous-flow reactor process that converts organic dairy manure into a rich microbial and diverse soil amendment with the help of earthworms (E. fetida). The process is designed to deliver a premium, professional grade soil amendment that meets the requirements of the most demanding commercial growers.

TerraVesco’s Vermi-extract is the liquid version of the foundational vermicompost product and is designed to deliver similar efficacy through irrigation systems, drip lines or spraying devices.


The vermiculture industry is comprised of an eclectic array of small, regionalized, undercapitalized competitors that lack product consistency, production scalability and significant commercial market penetration. TerraVesco has the necessary products, expertise, reputation, processes, and academic, scientific and managerial leadership to elevate it into a national leadership role in the vermiculture industry.

Terravesco has a multitude of advantages that make it a superior choice when compared with other companies offering similar products:

  1. A proprietary production process that is scalable and delivers a high quality, consistent product that meets the demanding standards of commercial growers. In addition, TerraVesco’s products are OMRI listed and CDFA certified* which is a significant differentiator in the industry.
  2. Considerable expertise in worm husbandry and vermiculture. Founder and President, Jack Chambers is a recognized, industry leading authority on worm husbandry and a master of the continuous flow-reactor production process.
  3. Strong positioning as a science and data driven company. TerraVesco is elevated in the commercial agricultural space by pursuing rigorous academic and commercial field trials, maintaining an Academic and Scientific Advisory Board of leading scientists in horticulture, plant pathology, viticulture, soil science and microbiology, and having a Chief Scientist with a Ph.D. in Plant Pathology as part of the senior management team.
  4. An enviable existing customer list of some of the most successful and admired premium winemakers in Northern California. In addition, close proximity to these key customers reduces shipping and transportation costs.


*OMRI and CDFA certifications for TerraVesco’s vermicompost products are currently held under the name of the Sonoma Valley Worm Farm. The company is currently applying for OMRI and CDFA certification under the name of TerraVesco for Q1 2015.

Eating organic is a huge trend. The green, sustainable movement is strong, sophisticated, institutionalized and global. The green sustainable movement is driven by strong generational values and preferences.

According to the 2013 US Families’ Organic Attitudes and Beliefs Study, conducted by the Organic Trade Association: (include the Organic Trade Association logo)

  • 81% of parents report buying organic products, up significantly from the 73% who reported doing so in the 2009 benchmark study.
  • “Newly Organic” consumers–relatively new entrants to the organic market–have increased to 41% of families.
  • 52% of families report that they are buying more organic items than they were 12 months ago.
  • 97% of organic buyers say they bought fruits or vegetables in the past 6 months.
  • 94% of organic buyers believe that organic foods are better for you and for the environment
  • 48% of organic consumers believe that organic is healthier for their families

As commercial growers want to participate in the higher prices and profits offered by certified organic commodities, they must comply with the stringent USDA rules and regulations outlined in the National Organic Program (NOP). Farmers cannot gain organic certification until three years after they last applied chemicals. 

TerraVesco Vermicompost and Vermi-extract help farmers adhere to NOP standards.

The Sonoma Valley Worm Farm, LLC (TerraVesco) was founded by Jack Chambers in 1992. The farm was the original site of a worm husbandry operation that supplied worms to local bait shops and local gardeners to improve the soil in their gardens. Jack, a commercial airline captain and avid gardener living in Sonoma, California, had purchased worms at the farm to begin vermicomposting table scraps in a compost bin in his backyard. Jack was astounded by the ability of the worms to quickly convert the table scraps into a rich, dark humus that could be used to improve the quality of the soil in his gardens. Jack was hooked.

Jack purchased the worm farm in 1992. Over the next twenty years, he traveled to vermiculture and compost conventions all over the world to learn as much as he could about worm husbandry, composting, and the development of new technologies for producing vermicompost and vermicompost teas. He sought out the knowledge and opinions of leading academics who were just beginning to research the efficacy of vermicompost in building healthy soils and plants. He studied the new methods and technologies that were being used to improve and refine the production process for vermicompost. He researched how earthworms convert waste into an organic soil amendment that leads to healthier, more beautiful flowers, and better tasting herbs, fruits and vegetables. Through trial and error, and first-hand observation of the significant improvement in the performance of his own garden and vineyard, Jack was convinced that there was a great opportunity to help local organic farmers, wine grape producers and gardeners grow healthier plants in a natural, organic and sustainable way by engaging the help of the selfless earthworm.

Over the years, Jack’s boundless passion for worm husbandry and vermicomposting has enabled him to become one of the industry’s leading authorities. Jack is frequently sought out by others looking to learn more about worm husbandry, vermicomposting, and the production process that he’s successfully developed over the years. At TerraVesco, Jack has continued to provide high-quality vermicompost and extract to the local agriculture community, wine grape producers, and to Master Gardeners and gardening enthusiasts looking to improve their soils organically.
