Tree Disease identification, symptoms, treatment options for tree diseases

There are many different diseases that affect landscape trees and shrubs. Control of tree and shrub diseases cannot be properly accomplished until the disease pest is identified. Identification of tree and shrub diseases is crucial because, although most diseases can be controlled, there are some diseases that cannot be controlled. Disease control on landscape trees and shrubs can sometimes be accomplished by more than one method, depending on the particular disease that if infecting your landscape plants. Even if you are going to attempt to control a disease that is infecting your landscape trees or shrubs you should consider consulting a local arborist. Related: Permaculture

Tree Encyclopedia Trees have three principle features that distinguish them from all other plants. First, they have a woody stem, roots and branches which do not die back in winter, but continue to grow year after year. From the moment of its germination, a tree remains visible; from the tallest Sequoia to the smallest garden fruit tree, this principle of growth remains constant. Trees live longer than any other organism on earth. Trees commonly live more than 1,000 years, and many grow considerably older. A bristlecone pine, Pinus longaeva, at Schulman Grove in California has been documented both by core drilling (a pencil-thin core is taken from the tree’s trunk, and the rings are counted) and by carbon-dating as being 4,700 years old. Pando (Latin for “I spread”), aka “the trembling giant,” is a clone colony of male quaking aspen, (Populus tremuloides) a single living organism identified by identical genetic markers. Family Aceraceae: Maples are some of our most familiar and beloved trees.

Society of American Foresters Biochar Biochar created through the pyrolysis process. History[edit] Left - a nutrient-poor oxisol; right - an oxisol transformed into fertile terra preta using biochar Pre-Columbian Amazonians are believed to have used biochar to enhance soil productivity. The term “biochar” was coined by Peter Read to describe charcoal used as a soil improvement.[9] Production[edit] Pyrolysis produces biochar, liquids, and gases from biomass by heating the biomass in a low/no oxygen environment. The Amazonian pit/trench method[6] harvests neither bio-oil nor syngas, and releases a large amount of CO2, black carbon, and other greenhouse gases (GHG)s (and potentially, toxins) into the air. Centralized, decentralized, and mobile systems[edit] In a centralized system, all biomass in a region is brought to a central plant for processing. Pyrolysis technologies for processing loose and leafy biomass produce both biochar and syngas.[15] Thermo-catalytic depolymerization[edit] Uses[edit] Carbon sink[edit] Soil amendment[edit]
