817Hursh, C.R.1928Litter keeps forest soil productive.Hursh, C.R. 1928. Litter keeps forest soil productive. Southern Lumberman 133(1734): 219-221.Journal ArticleForest soils are, for the most part, self-fertilized by organic material derived from litter. Litter has a beneficial effect on the ability of soil to absorb and retain moisture, on chemical characteristics, and on biological activity. The effects of fire and aspect on litter production are discussed.

Further studies of the balanced water cycle on experimental watersheds. Transactions, American Geophysical Union 28: 421-424.Journal ArticleMaintaining a chronological account or balance of the components of the water resource on a watershed is frequently valuable in hydrology studies. In this paper, a time period for studying this balance is described: the period between the times of maximum watershed storage at the end of each dormant season. Changes in ground-water storage are thus taken into account, and, by choosing the beginning and ending points of the year at times of field capacity, changes in water storage in the soil mass are minimized.

The natural forest, which once occupied the Shimba Hills, is a more desirable cover than grass for maximum-sustained water yield because water additions from mist and dew are greater from the forest.

Forest Science 2: 82-91.Journal ArticleOn Coweeta Watershed 19, the laurel and rhododendron understory (22 percent of total basal area) was cut between December 1948 and March 1949. A 4-inch increase in water yield was achieved the first year after treatment, and the yield increase declined during the next 6 years. This increase was almost evenly divided between the growing and dormant seasons.

Principles of watershed management based on current research, pp.15-19.OtherWatershed management is the integrated management of all renewable resources of a drainage basin for maximum water production or control consistent with other economic uses of the land. While this definition certainly encompasses structural works of improvement, I am going to focus on land treatment; and mostly I will focus on wildland management, since discussions of this are often subordinated to agricultural aspects in meetings of this sort.

Conversely, the sponge effect of the forest floor, although well recognized, has received limited study. In order to determine the moisture content of litter in pine stands in the Southeast, data were collected in a 12-year-old loblolly plantation on an old-field site.

Journal of Forestry. 58(10).Journal ArticleBecause the growth rate in old trees slows down so markedly, we cannot under our present economy afford to let forests grow to old age until we utilize them. In fact, as the intensity of forest management increases, rotations continue to shorten. Consequently, there is great value in preserving some areas of old-growth or virgin forest to serve as bench marks--areas which show the natural potential of the site, the relation of soil and vegetation, and the impact of disease.
