From the text ... 'About 5 million tons of tree bark were produced in 1966 as 'waste' from the Pacific Northwest wood products industry, more than two-thirds of which (table 1) came from Oregon and Washington. If all this bark were to be concentrated in one place, the resulting pile would cover 1 square mile to a depth of 10 feet... The time is ripe to solve the troublesome problem of waste bark disposal with its attendant contribution to air pollution. In this paper, we shall discuss the possibilitites for use of large volumes of bark for agricultural purposes and summarize our knowledge of the various properties of bark having a direct bearing on its use.'
