  • cross reference for relating genetic Soil classification of china with wrb at different scales
    Geoderma, 2010
    Co-Authors: Dongsheng Yu, Shengxiang Xu, Eric D Warner, Yuguo Zhao, Huifeng Wang, Zitong Gong
    Abstract:

    Soil classification systems are not consistent between countries or organizations thereby hindering the communication and organizational functions they are intended to promote. World Reference Base for Soil resources (WRB) was endorsed and adopted by the International Union of Soil Sciences (IUSS) as the standard for Soil correlation and international communication. As a widely used classification system in China, Genetic Soil Classification of China (GSCC) differs from WRB in its underlying understanding about the genetic process. The differences limit communication between Chinese and international Soil scientists because there is no standard cross-reference between GSCC and WRB. This paper describes a cross-reference of GSCC to WRB at different scales. The basic Soil data set used in the study includes 7292 Soil profile data (representative of Soil series) collected throughout China. First, a brief history of Soil classification in China is provided to familiarize readers with GSCC and its origins. Second, cross-reference at the pedon scale is addressed based on data compiled from 51 monoliths acquired in China by the International Soil Reference and Information Centre (ISRIC) in the 1980s and 1990s. Each of GSCC's 7292 Soil series is classified into their equivalent reference Soil groups according to the WRB Soil reference key. Pedon scale cross referencing is discussed using the database from the Second National Soil Survey of China. Third, the concept and calculation of referencibility is introduced and the process for cross-referencing Soil classification systems at national scale is addressed. GIS based analysis generates 60 reference results between GSCC Soil great groups and WRB reference group. Results demonstrate that there is great variability in the maximum referencibility between Soil great groups of GSCC and WRB Soil groups, which ranged from 29.4% to 100%. In terms of the maximum referencibility, it can be divided into three categories: high (80%–100%), intermediate (50%–80%), and low (< 50%). Among the 60 Soil great groups of GSCC, 12 could be labeled as high maximum referencibility, 27 categorized as medium maximum referencibility and the remaining 21 are associated with low maximum referencibility. Finally, the main cause of low maximum referencibility is explored and the potential solution to improve cross reference accuracy was proposed.

  • Advancing the Emerging Field of Hydropedology First International Conference on Hydropedology; University Park, Pennsylvania, 28–31 July 2008
    Eos Transactions American Geophysical Union, 2008
    Co-Authors: Henry Lin, Kamini Singha, David J. Chittleborough, H. J. Vogel, Sacha J. Mooney
    Abstract:

    Both Soil science and hydrology are at a critical threshold of exploring breakthroughs. Synergies are expected by bridging classical pedology with Soil physics, hydrology, geomorphology, and other related bio- and geo-Sciences to address complex Soil and water interactions across spatiotemporal scales. Holistic study of the Earth's critical zone (i.e., the critical interface between the surficial solid Earth and its fluid envelopes, which ranges from the top of vegetation to the bottom of aquifers) demands interdisciplinary systems approaches to tackle a wide array of environmental, ecological, agricultural, geological, and natural resource issues of societal importance. In this spirit, and aiming to advance the emerging field of hydropedology, the first international conference on hydropedology was held at Pennsylvania State University (Penn State) with the theme “Water and Soil: Key to Sustaining the Earth's Critical Zone.” The International Union of Soil Sciences' Working Group on Hydropedology organized this meeting, with main sponsorships from the U.S. Department of Agriculture's National Research Initiative and Penn State.

  • a simple group work approach for effective field work a Soil Sciences case study
    Journal of geoscience education, 2006
    Co-Authors: Sacha J. Mooney
    Abstract:

    Recent educational reports in the UK have suggested that the developments of key transferable skills, such as group working, are a necessary outcome of higher education. However with current logistical problems in higher education, such as increased student numbers, the effective use of group work in field work in particular, is currently a subject of much discussion. A group working exercise based around a one-day Soil examination study, as part of a one week residential field week, was developed to evaluate the effectiveness of group work by assigning formalized, rotational, individual group roles. Student responses and instructor observations suggested that there was considerable merit in this approach in terms of development of academic and transferable skills, and in the generation of a positive, experiential learning environment. It is suggested that that this could serve as a precursor to a more formalized identification of group roles that would benefit both instructors and students alike in terms...
