The pulp industry in the south is now larger than in all other parts. of the Nation combined. In the years since 1946, construction of 2S new mills and the expansion of existing mills has more than doubled plant capacity. The annual cut of pulpwood bolts has increased proportionately, and a new source of raw material has been developed from the coarse residues at sawmills.

To realize the crop production potential of soils it is necessary to first have a knowledge of their chemical, physical and biological properties and reactions and then to so alter these properties and reactions to effect a medium optimum for plant growth. In the past, soils have been classified primarily on the basis of physical characteristics observable in the field. Although the soil survey reports resulting from field studies of observable soil physical characteristics provide valuable information, several physical and chemical measurements on soils provide information useful in the...

Widespread dieback and mortality of hardwoods has been noted in the South during recent years. In general, losses have been most severe in certain areas of cottonwood, sweetgum, and black willow. Some damage also has been noted in red oaks, especially Nuttall; and in elms, green ash, sycamore, and some less important species. On uplands, mortality has occurred in sassafras, hickory, sweetgum, oaks, and yellow-poplar. Drought is now understood to be the basic cause. This article discusses some of the conditions associated with drought; and some of the ways in which it kills trees. Some...

In recent years farmers and sportsmen have built many temporary shallow-water impoundments in southern hardwood forests. While the main purpose has been to attract waterfowl, a recent study shows that these forest lakes, if properly managed, can also benefit the timber.

A unique method for measuring consumptive use and transpiration of water by forests was devised for a study near Stoneville, Mississippi.

Mississippi forests are now growing more pine but less hardwood than is being cut, according to a new survey of the State's forest resources. But because many timber stands are not fully stocked, growth is only about half the potential.

Meandering along the eastern edge of the Mississippi River Valley from Cairo, Illinois, to Baton Rouge, Louisiana, are 4% million acres of forested uplands variously called the Loess Hills, the Thick Loess area, the Brown Loam Bluffs, the Bluff Hills, or just the Bluffs. The area (Fig. 1) is well known to foresters and lumbermen who work in the Lower Mississippi Valley, for it is potentially one of the most productive hardwood sites in the nation.
