Compost

Field Trials;
 I am field testing for the 09 corn season with JMU and consultation  Dr. Hepperly at Rodale Institute.

Ten research priorities were identified at the IBI conference, The following priorities I hope to address:
• 1- Economy research/market research
• 2- plant+soil research depending on biochar
• 5- field trials
• 8- application to soil (depending on agricultural or other
systems/remediation`)

Planting date: June 24th.
Two split plots , which each are split into a 20% (27 tons/Ac) & 5% (7 tons/Ac) application rates,
All chars soaked in tarps for 1 month, all chars were mixed 1:2 by volume with finished poultry litter compost and roto-tilled to 5 inch depth.

Charcoal in Container Growing Media

After visiting Richard Haard and Larry Williams in early 2007 I started discussing the use of charcoal with various nursery growers and researchers in the West. A commercial nursery in California became interested in substituting charcoal for vermiculite in a growing media - soilless substrate - for container grown tree seedlings.

Wood ash admixture to organic wastes improves compost and its performance

Throughout Europe, increasing amounts of wood ash are produced from biomass incineration plants. Most of these ashes are currently landfilled, despite their nutrient and micronutrient contents. The aim of this research was to find a way to return wood ash from biomass incineration plants into the natural cycle
of matter. Three composts from source separated organic waste were produced with 0%, 8% and 16% ash admixture. The composting process was monitored by in situ measurements of temperature and CO2 concentration in the windrows. Maturation of the composts was observed through the parameters basal respiration, microbial biomass,metabolic quotient, Corg, Ntot, C/N-ratio and plant growth tests with cress.

Charcoal in agriculture: Experimental research at Fourth Corner Nurseries
Richard Haard, Fourth Corner Nurseries, Bellingham, Washington, January 3, 2008

Greetings

I just finished over the last few days organizing images and data from my charcoal experimental plots. I am presenting a new set of posters showing root systems of the native shrub, Lonicera involucrata or black twinberry that I used as an experimental subject in these treatment plots this summer.

This will be the last of a series of piecemeal postings about my findings on the terrapreta reading list. In time, I will prepare a summary of what I have accomplished this year, the shortcomings, what I feel I have learned from this work about using charcoal and my plans for continuing this experiment for 2 or more growing seasons.

This is Puffergas' first test of growing potatoes in switchgrass compost. The potatoes were grown in containers and charcoal was added to the compost.

Biochar Trials at Fourth Corner Nursery
Richard Haard, Fourth Corner Nursery, Bellingham, WA, December 6, 2007
Hello All - For your interest

I submitted to Tom for posting [attached] some initial soil analysis data from my charcoal block study. In am just beginning to compile a report on this work. When it is posted you will see soil analysis results averaged for each replication(2) for 2 dates , April and October. Listed are pH, Buffer pH, OM, Nitrate, Cation Exchange Capacity (CEC) and base exchange components, % Potassium, % Magnesium, % Calcium. Other soil analysis was taken but not presented here.

Keep in mind this is a 2 to 3 year study and no additional additions or treatments will be done other than continuous cropping and harvest of all growth, tops and roots, at our bare-root native plant nursery. It is my attempt to emulate Christoph Steiner, et al research in Manaus
