This journal uses ScholarOne Manuscripts (previously Manuscript Central) to peer review manuscript submissions. Please read the guide for ScholarOne authors before making a submission. Complete guidelines for preparing and submitting your manuscript to this journal are provided below.

Abstract. Should not exceed 250 words. Avoid abbreviations, diagrams, and references. It must be complete and understandable without reference to the text. Uninformative phrases, such as ‘‘the results are discussed'' or ‘‘implications have been considered in this paper'' are not acceptable.

Keywords. Identify important subjects covered by the article that are not listed in the Title. Authors must provide from three to ten alphabetized keywords or two-word key phrases. They should be placed following the Abstract.

Headings. All headings for sections and subsections should be typed in lowercase letters and placed on separate lines. Do not underline any headings.  

References. Literature citations in the text should be by author's surname and year; when references are by three or more authors abbreviate to the first surname and et al.: ‘‘Smith (1982) has shown. . . Previous work (Smith & Jones, 1982; Jackson, 1983a, b) has demonstrated that . . . Jackson et al. (1982) have shown that . . .'' The list of citations should be given in alphabetical order, with all authors and editors listed. Full titles of periodicals, books and articles, and full pagination of articles should be given. Follow these examples:

Journal article: Halvorson, J. J., H. Bolton Jr., and J. L. Smith. 1997. The pattern of soil variables related to Artemisia tridentata in burned shrubsteppe site. Soil Science Society of America Journal 61: 287–294.

Tables and Figures. Tables and figures should not be embedded in the text, but should be included as separate sheets or files. A short descriptive title should appear above each table with a clear legend and any footnotes suitably identified below.All abbreviations should be described in footnotes, indicated by superscript letters, beginning with a in each table. Use of explanatory footnotes is encouraged. Do not use vertical lines to separate columns. Horizontal lines are used to separate headings only.

Units of Measurement and Abbreviations. Use of the International System of Units (SI, Syste`me international d'unite´s) is required. In the text and tables use the minus index (e.g., ug h1) instead of a slash and conform with the SI abbreviations. Use chemical designations instead of spelling out common chemical names (e.g., ‘‘CO2 release, C and N cycling, HC1, N2-fixation''). Define each uncommon abbreviation and introduce it in parentheses the first time it is used, e.g., ‘‘modified universal buffer (MUB) was used.'' The conventional designation of author's name(s) of a binomial scientific name of organism must be noted the first time the name of the organism is introduced in the main text (except in the title). Fertilizer values should be expressed in terms of P, K, etc., not P2O5, K2O, etc.

Notes. Notes, not exceeding 1500 words, are intended for the presentation of brief research reports that do not warrant fulllength papers. The Notes receive the same review, and they are not considered preliminary communications. Each Note must have an Abstract of no more than 100 words and Keywords. Do not use section headings in the body of the Note. The number of figures and tables be kept to a minimum. The References section is identical to that of full-length papers.

Reprints. Each contributor will be granted complimentary e-access to their article, with the ability to download it in PDF format, provided the contributor has submitted an email address to the publisher. Contributors will have the opportunity to buy reprints of their article at the proof stage of production.
