Download or read book Soil Mapping and Process Modeling for Sustainable Land Use Management written by Paulo Pereira and published by Elsevier. This book was released on 2017-03-13 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Mapping and Process Modeling for Sustainable Land Use Management is the first reference to address the use of soil mapping and modeling for sustainability from both a theoretical and practical perspective. The use of more powerful statistical techniques are increasing the accuracy of maps and reducing error estimation, and this text provides the information necessary to utilize the latest techniques, as well as their importance for land use planning. Providing practical examples to help illustrate the application of soil process modeling and maps, this reference is an essential tool for professionals and students in soil science and land management who want to bridge the gap between soil modeling and sustainable land use planning. - Offers both a theoretical and practical approach to soil mapping and its uses in land use management for sustainability - Synthesizes the most up-to-date research on soil mapping techniques and applications - Provides an interdisciplinary approach from experts worldwide working in soil mapping and land management

Download or read book Manual of Methods for Soil and Land Evaluation written by Edoardo A.C. Costantini and published by CRC Press. This book was released on 2009-01-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of the manual is to supply an operational tool for pedologists, agronomists, environmentalists, and all of the other specialists who carry out land evaluation for agriculture and forestry or, more generally, stakeholders and policy makers who make decisions at the local level based on the knowledge of the nature of soil. Discussion of the topics is not only technical and operational, but also in-depth and didactic; therefore, the text may also be used as a valid complement for students majoring in subjects that involve soil use, management and conservation. The literature offers a wide choice of possible soil and land evaluation methods, while knowledge of the relationships existing between the physical characteristics of lands, particularly those of soils, and the requirements of specific uses is limited.
Download or read book Soil Sampling and Methods of Analysis written by M.R. Carter and published by CRC Press. This book was released on 1993-07-06 with total page 866 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Sampling and Methods of Analysis is a practical methods manual and resource handbook that covers a wide array of methods for analyzing soil chemical, biological, biochemical, and physical properties. Soil testing for plant nutrients and methods to characterize organic soils and frozen soils are also provided. The book presents recent improvements in methodology, outlines new methods, and characterizes the best methods available for selecting appropriate analysis techniques. Methods have been selected for their accuracy, speed, and ease of duplication. References are provided for each method. The book is ideal for scientists, engineers, and students in agriculture, horticulture, forestry, geography, remote sensing, environmental science, and land-use planning.

Available in PDF, EPUB and Kindle. Book excerpt: A Field Survey and mapping was conducted after photo interpretation at a scale of 1:11,000 in an area of Northeast Scotland having varying geological features, physical conditions and land use. Mineralogical and Micromorphological analysis of modal pedo-units samples were carried out. Two Transects were marked out for land cover classification and soil mapping using the following remote sensing techniques: Aerial Photo-Interpretation (API), Landsat MSS and Airborne Thematic Mapper (ATM). MSS bands 4, 5, 7 and the corresponding ATM bands 3, 5, 6 were used in order to highlight the effects of spatial resolution. Five image classification techniques, Density Slicing (DS), Unsupervised Cluster Analysis (CL), Box Classification (BX), Maximum Likelihood (ML) and Visual Interpretation (VS) were used to separate six major land classes (urban, forest, agricultural land, moorland, bare soil and water). For soil survey and mapping the land cover classifications were compared with the various soil units in the study area. There is a weak correlation between the mineralogy and the soil types but the micromorphology correlated well with the soil types. Accuracy test for MSS August shows that ML has the highest classification accuracy having 70.0-75.6%. For MSS April computer aided VS having 72.1-77.6% is the most accurate. For the ATM the Unsupervised algorithm cluster analysis is the most effective having accuracy range of 86.6-90.6%. The comparison of the three remote sensing techniques shows that for land cover classification API is the most accurate having 93.3% followed by ATM bands (3, 5 and 6) CL having 86.6-90.1%. Landsat MSS had only 72.1-72.6%. The lower than expected value for the ATM is probably due to inappropriate and inadequate waveband selection (3 out of 11 bands). For soil survey the ATM CL analysis is the most effective. Accuracy for API and ATM are 70.6-76.2% and 86.9-90.9% respectively. It is expected that higher classification accuracy can be obtained from the ATM data by adequate waveband selection. Those suggested are bands 2, 3, 4, 5, 7, 10 and 11.
