Maintenance of Productivity under Short Rotations in Japan
Forest fertilization, one of several integrated intensive forest cultural practices, began in Japan about a century ago. Fertilization of young plantations is practiced to hasten crown closure and reduce time for weeding. Fertilization of established stands to increase growth an shorten rotations is being researched and beginning to be practiced. Research is in progress on potential hazards to the environment from forest Fertilization. Because of a developing shortage of forest laborers, it is expected that the Japanese will need to introduce more mechanization to their intensive forest cultural practices.
