Fall Application Of Fertilizer, Kenneth L. Wells
Fall Application Of Fertilizer, Kenneth L. Wells
Soil Science News and Views
Fall application of fertilizer offers the advantages of (1) getting a job done which can delay early spring planting, (2) being able to get over fields when they are usually drier and less likely to compact, and (3) more often getting a price break from fertilizer dealers. Several crop-related advantages also apply and are discussed below. In terms of nutrients which can be fall applied, phosphate and potash are well adapted, Both these nutrients react strongly enough with soil to resist overwinter leaching. and the requirements for next year's production can safely be applied in the fall. Fall use of …

Forestry
A discrete version of the continuous joint production model in economic theory is presented for use in designing multiple-use projects and identifying efficient management prescriptions for forest planning. Data requirements are less demanding than the continuous theoretical model, yet some of the more important features are maintained. Models can be formulated graphically or as mixed-integer programming problems that are easily solved via computerized routines.

The Delphi Method: Application To Elk Habitat Quality, United States Department Of Agriculture, Forest Service
Wildlife Conservation and Management
This paper reports on the results of a study designed both to gather important information through Delphi and to evaluate several key features of the Delphi process. We intend to present information developed, and also describe and discuss Delphi so as to make resource managers more comfortable with it, aware of its potential, and willling to consider it along with other information gathering tools.
