Erosion Control & Wildlife Plantings for Forestry Operations
http://www.pfmt.org/wildlife/erosion.htm
Timber management creates openings in the form of roads, stream crossings, log decks, skid trails, and firebreaks. Establishing vegetative cover on these areas reduces soil erosion and prevents offsite sediment. The purpose of this publication is to provide forest land managers with a variety of seeding mixtures that will stabilize sites and provide benefits to many species of wildlife.

FOREST SOILS AND SITE INDEX
http://www.ces.ncsu.edu/nreos/forest/woodland/won-07.html
Soil quality is the most important factor in forest management decisions. Soils will determine which tree species yields the greatest timber volume, the time to harvest, and ultimately, the investment a landowner must make to yield an acceptable economic return from forest management.

Keep track of soil fertility when growing poth pines, pinestraw.
http://www.forestry.uga.edu/warnell/research/html/forestry/pinestraw.html
Pinestraw contains important nutrients like nitrogen, phosphorous, calcium and magnesium that are returned to the land as the pinestraw breaks down. Some producers worry that by removing the pinestraw every year, they are hurting the productivity of their trees.

Nitrogen in Mississippi Soils
http://msucares.com/pubs/infosheets/is767.htm
Field crops can use more nitrogen than Mississippi soils can provide in a growing season, so it must be added for economical crop production. However, too much may lessen yields and quality, while entering into ground or surface water.
