Dave's Organic Gardening,
Organic Gardening. Local Gardener. Sustainable Gardens.

Dave gave a presentation primarily about soil health and how it affects gardening. He has continued his studies and demonstrated significant knowledge in this field. He was especially influenced by Dr. Elaine Ingham.

Dr. Elaine Ingham's education and focus has been in microbiology with an emphasis on soil. Her books are all on compost tea. She also has numerous publications on different aspects of soil biology e.g., bacteria, fungi, protozoa, etc. She is founder of Soil Foodweb Inc.

Mapping Analysis and Printing System

Dave described the basics of the concept of Soil Food Web.

Dave was thorough in his presentation of this subject. He also provided Dr. Elaine Ingham's compost tea recipe. I have supplied that here at the end of this article.

Dave also described an alternative to the harsh chemical glyphosate (sold as Roundup): AVENGER, available online and at Agriturf off Las Positas. He provided a couple alternatives, including salt and vinegar. Some plants will die when fed vinegar, most will die when fed salt. Between these two many invasive plant infestations may be solved. When these techniques fail, try AVENGER.

Dr. Elaine Ingham's Basic Tea Recipe:

  1. 25 gallons of water, aerated to remove chlorine, add two teaspoons of a humic acid solution (preferably humic acid extracted from your own compost).
  2. 1 to 2 tablespoons of humic acid diluted in 2 cups of water BEFORE adding to the COMPOST TEA water OR 1 to 2 tablespoons of fish hydrolysate (pre-diluted to neutralize the acid preservative according to the label on the container).
  3. 1/2 cup of kelp mixed in 5 cups of water BEFORE addition to the compost tea.
  4. 5 pounds of good aerobic (good smelling, like deep forest soil) compost with excellent bacteria, fungi, protozoa in the compost. Using a microscope, assess the compost: Using a 1:5 dilution of compost, 400X total magnification, there should be a MINIMUM of thousands of bacteria in each field of view, 1 strand of fungal hyphae in each 5 fields, 1 flagellate or amoebae in each 5 to 10 fields of view and 1 beneficiall nematode per drop.
Additional foods if needed to improve fungi: 1 cup steel cut oats, or bran flour, or shrimp shells (no protein on the shells!) put in the compost bag with the compost.

Replace humic acids with the same amount of fish hydrolysate if the plants need a nitrogen boost.
