Trees

MASS Laboratory has been working with Bartlet Tree Experts on an series of plot tests, and field tests to study the use of biochar in caring for trees, particularly urban street trees.

MASS Laboratory has a great description of the work here:

Country: 

Arborists in Chicago are studying the results of biochar on trees growing in urban soils that are typically hostile to trees. This research is part of a larger urban-soils study that includes applications of biochar in greenhouse and field plot settings at The Morton Arboretum. The Bartlett Tree Research Laboratories have also been testing adding biochar to the soil mix when planting trees. More information and media coverage of this study about biochar and urban tree care can be found on the Bartlett Tree Experts web site.

Bamboo Biochar Trial 2006 China
Robert Flanagan, SAFFE, China, July 2007

This is a trial we started last year using bamboo charcoal as a soil amendment. Last year we sent Cornell University soil samples last year and hope to continue this research with them in the future.

Alternatives to Methyl Bromide in Southern Forest Tree Nurseries
Clark W. Lantz, 1Nursery/Tree Improvement Specialist, Cooperative Forestry, USDA Forest Service, Atlanta, GA, 1997

Forest tree nurseries in the southern US are growing an average of 1.2 billion seedlings per year or about 80% of
the total seedling production in the US. This annual nursery production supports a planting program of
approximately 1.8 million acres-an area about the size of the states of Delaware and Rhode Island combined.
Fumigation is practiced by 89% of these nurseries for both disease and weed control. The chemical of choice has
been methyl bromide, applied every year by some nursery managers and every second year by others.

A few
nurseries have used fumigation only on an "as-needed" basis to deal with chronic disease problems. One nursery
has successfully grown high quality annual seedling crops without fumigation for 16 years. This nursery has
emphasized intensive soil management with bark mulch and aggressive weed control.
