NONLIVING FACTORS - PROBLEM DIAGNOSIS

HERBICIDE INJURY DIAGNOSIS

APPLIED WEED SCIENCE. 1985. Merrill A. Ross and Carole A. Lembi (Purdue University). 340 pp, hard cover. Burgess Publishing Company, Minneapolis, Minnesota. The authors’ writing style is not stilted or heavy with technical jargon. The book is very well-written: information is accurate, concise, clearly phrased and presented in a logical sequence. It is an interesting book that holds the reader’s attention. The information is “applied” in the sense that the reader can readily relate the information to actual plant production and weed control situations. Chapter 14 on “Troubleshooting” is a useful guide to diagnosing the cause(s) of herbicide failure or injury problems. Interpretation of observed “patterns”, information to collect when making an on-site investigation, identifying injury symptoms on individual plants, and interpreting findings are explained. The book is well indexed and cross-referenced so the reader can quickly find specific information. The “Glossary” provides quick definition of terms. Available for $29.95/ copy from AgAccess + $1.50 shipping charge, P.O. Box 2008, Davis, CA 95617, telephone (916) 756-7177.

SOILS

MANUAL FOR JUDGING OREGON SOILS, Oregon State University Extension Service Manual 6 (September 1984). J.H. Huddelston and G.F. Kling. Available for $7.50 plus 15% shipping and handling from: Publication Orders, Agricultural Communications, Oregon State University, Corvallis, OR 97331- 2119.

This 81-page manual is a good introduction to Oregon soils and a guide to evaluating and judging specific soils. The chapters on Properties of Soil Horizons (soil colors, mottling, texture, structure), Properties of the Whole Soil (effective rooting depth, water-holding capacity, permeability, erosion potential, drainage), Site Characteristics (slope, landform), and Management Interpretations guide the landowner in acquiring more information and understanding of the soil. The manual was primarily designed as a guide to students preparing for soil judging contests, and it is equally valuable to others who evaluate soils.
