  • Paxton Soil Series Is Named for the Town of Paxton in Worcester County Massachusetts Where It Was First Described
    Paxton Massachusetts State Soil Soil Science Society of America Introduction Many states have a designated state bird, flower, fish, tree, rock, etc. And, many states also have a state soil – one that has significance or is important to the state. The Paxton is the offi- cial state soil of Massachusetts. Let’s explore how the Paxton is important to Massachusetts. History The Paxton soil series is named for the town of Paxton in Worcester County Massachusetts where it was first described. The series was established in 1922, described in the Soil Survey of Worcester County in 1927, and then in 1991 it was designated as the official state soil of Massachusetts. Created by the movement of glaciers thousands of years ago, Paxton soils can be found throughout New England and are exemplified by scenic rolling hills dotted with dairy farms. It is considered one of the most productive soils for agricul- ture in New England. What is Paxton Soil? Paxton soil is made of well drained loamy soils formed on wind deposited material that sits on top of rock deposited by glaciers. Classified as a coarse-loamy soil, Paxton soils possess soil particles that are at the larger end of the textural spectrum. Being composed of material scraped from the surface of the landscape over which glaciers traveled, its mineral composi- tion is varied. The rocks contributing to Paxton soils include schist, gneiss, and granite. The clays in its composition have good cation-exchange ca- pacity, although the pH of these soils is low. A cation is a positively charged ion (such as an atom or molecule) which influences the soil’s ability to hold onto essential nutrients and provides a buf- fer against soil acidification.

  • The Soil Survey
    The Soil Survey The soil survey delineates the basal soil pattern of an area and characterises each kind of soil so that the response to changes can be assessed and used as a basis for prediction. Although in an economic climate it is necessarily made for some practical purpose, it is not subordinated to the parti­ cular need of the moment, but is conducted in a scientific way that provides basal information of general application and eliminates the necessity for a resurvey whenever a new problem arises. It supplies information that can be combined, analysed, or amplified for many practical purposes, but the purpose should not be allowed to modify the method of survey in any fundamental way. According to the degree of detail required, soil surveys in New Zealand are classed as general, . district, or detailed. General surveys produce sufficient detail for a final map on the scale of 4 miles to an inch (1 :253440); they show the main sets of soils and their general relation to land forms; they are an aid to investigations and planning on the regional or national scale. District surveys, for maps, on the scale of 2 miles to an inch (1: 126720), show soil types or, where the pattern is detailed, combinations of types; they are designed to show the soil pattern in sufficient detail to allow the study of local soil problems and to provide a basis for assembling and distributing information in many fields such as agriculture, forestry, and engineering. Detailed surveys, mostiy for maps on the scale of 40 chains to an inch (1 :31680), delineate soil types and land-use phases, and show the soil pattern in relation to farm boundaries and subdivisional fences.

  • A Guide to Potential Soil Carbon Sequestration Land-Use Management for Mitigation of Greenhouse Gas Emissions
    A Guide to Potential Soil Carbon Sequestration Land-Use Management for Mitigation of Greenhouse Gas Emissions By H.W. Markewich and G.R. Buell Terrestrial carbon sequestration has a potential role in reducing the recent increase in atmospheric carbon dioxide (CO2) that is, in part, contributing to global warming. Because the most stable long-term surface reservoir for carbon is the soil, changes in agriculture and forestry can potentially reduce atmospheric CO2 through increased soil-carbon storage. If local governments and regional planning agencies are to effect changes in land-use management that could mitigate the impacts of increased greenhouse gas (GHG) emissions, it is essential to know how carbon is cycled and distributed on the landscape. Only then can a cost/benefit analysis be applied to carbon sequestration as a potential land-use management tool for mitigation of GHG emissions. For the past several years, the U.S. Geological Survey (USGS) has been researching the role of terrestrial carbon in the global carbon cycle. Data from these investigations now allow the USGS to begin to (1) “map” carbon at national, regional, and local scales; (2) calculate present carbon storage at land surface; and (3) identify those areas having the greatest potential to sequester carbon. Ongoing efforts of the USGS to achieve these objectives are: • compilation and synthesis of site-specific data needed to estimate carbon storage and inventory in soils, reservoir sediments, wetlands, and lakes of the conterminous United States; • characterization of present-day carbon storage by Black Mountain Range, western North Carolina—an area landscape feature and environment; and of high carbon soils—looking north from summit of Mount Mitchell, highest peak in eastern United States.

  • Appendix D Soil Series Descriptions
    Appendix D Soil Series Descriptions Soil Series Descriptions Soil Orders Mollisols — This order covers a considerable land area of western and southern Minnesota and is the basis for the state's productive agricultural base. The formative syllable, oll, is derived from the Latin word mollis, or soft. Its most distinguishing feature is a thick, dark-colored surface layer that is high in nutrients. It occurs throughout the former prairie areas of Minnesota. The Latin term for soft in its name is descriptive in that most of these soils usually have a rather loose, low-density surface. Three suborders of mollisols occur in Minnesota: Aquolls, Udolls, and Ustolls. Alfisols — This order covers a large land area in Minnesota, part of which is now cultivated and part forested. Alf is the formative element and is coined from a soil term, pedalfer. Pedalfers were identified in the 1930s as soils of the eastern part of the United States with an accumulation of aluminum and iron. The alf refers to the chemical symbols for aluminum (Al) and iron (Fe). Alfisols are primarily fertile soils of the forest, formed in loamy or clayey material. The surface layer of soil, usually light gray or brown, has less clay in it than does the subsoil. These soils are usually moist during the summer, although they may dry during occasional droughts. Two suborders of alfisols occur in Minnesota: Aqualfs and Udalfs. Histosols — The formative element in the name is ist and comes from the Greek word histos, which means tissue. This is an appropriate association because these soils are formed from plant remains in wet environments like marshes and bogs.

  • Drummer Illinois State Soil
    Drummer Illinois State Soil Soil Science Society of America Introduction Many states have designated state symbols such as bird, flower, fish, tree, rock, and more. Many states also have a state soil – one that has significance or is important to the state. As there are many types of birds, flowers, and trees, there are hundreds of soil types in our state but Drummer is the official state soil of Illinois. How important is the Drummer soil to Illinois? History Drummer was first established as a type of soil in Ford County in 1929. It was named after Drummer Creek in Drummer Township. 1n 1987, Drummer was selected as the state soil by the Illinois Soil Classifiers Association over other soils such as Cisne, Flanagan, Hoyleton, Ipava, Sable, and Saybrook. Since then, Drummer has been repeatedly chosen by other as- sociations who work with soil. In 1992, the Illinois Association of Vocational Agriculture Teachers sponsored a state soil election in their classrooms and Drummer won by a margin of 2 to 1. In 1993, the statewide 4H Youth Conference also selected Drummer out of 6 nomi- nees. Also in 1993 at the FFA state convention, Drummer and Ipava were tied in the contest. Finally, in 2001, after many attempts, it was finally passed by the Illinois Legislature and signed into law by Governor George Ryan. What is Drummer Soil? It is the most common among the dark colored soils or “black dirt” of Illinois. The dark color is due to the high amount of organic matter inherited from the decomposition of the prairie vegetation that is growing on the soil.

  • A New Era of Digital Soil Mapping Across Forested Landscapes 14 Chuck Bulmera,*, David Pare´ B, Grant M
    CHAPTER A new era of digital soil mapping across forested landscapes 14 Chuck Bulmera,*, David Pare´ b, Grant M. Domkec aBC Ministry Forests Lands Natural Resource Operations Rural Development, Vernon, BC, Canada, bNatural Resources Canada, Canadian Forest Service, Laurentian Forestry Centre, Quebec, QC, Canada, cNorthern Research Station, USDA Forest Service, St. Paul, MN, United States *Corresponding author ABSTRACT Soil maps provide essential information for forest management, and a recent transformation of the map making process through digital soil mapping (DSM) is providing much improved soil information compared to what was available through traditional mapping methods. The improvements include higher resolution soil data for greater mapping extents, and incorporating a wide range of environmental factors to predict soil classes and attributes, along with a better understanding of mapping uncertainties. In this chapter, we provide a brief introduction to the concepts and methods underlying the digital soil map, outline the current state of DSM as it relates to forestry and global change, and provide some examples of how DSM can be applied to evaluate soil changes in response to multiple stressors. Throughout the chapter, we highlight the immense potential of DSM, but also describe some of the challenges that need to be overcome to truly realize this potential. Those challenges include finding ways to provide additional field data to train models and validate results, developing a group of highly skilled people with combined abilities in computational science and pedology, as well as the ongoing need to encourage communi- cation between the DSM community, land managers and decision makers whose work we believe can benefit from the new information provided by DSM.

  • Section C – Soil Information
    SECTION C │ Soil Information SECTION C - SOIL INFORMATION 1) Preface Soil information and its proper application can contribute to the solution of many waste disposal problems in Georgia. It can effectively be combined with geology, engineering and ecology to yield an integrated approach to environmental improvement. This Manual concentrates primarily on evaluating the suitability of soils for disposal of liquid waste from individual homes through septic tanks and subsurface soil absorption systems. It is hoped that the following information will help to point out how to avoid the mistakes frequently made in choosing suitable development sites where the soil is to be used for treatment and disposal of liquid waste. Such mistakes can result in increased land use conflict, environmental degradation and a waste of time and money. Although these sections of the Manual were developed to provide information to all people interested in solving relevant waste disposal problems where soil characteristics are contributing factors, the majority of the material will probably be most useful to environmental health specialists and other environmental health workers, surveyors, engineers, developers and other persons and groups frequently confronted with making significant land use decisions. 2) Introduction A. Soil and Environmental Health - Soil is a term that means different things to different people. To some it is a material in which plants grow in a yard or a field. To some, the color of the soil is important and they speak of red soil, yellow soil or blue clay. To others, the soil texture is important and they speak of sandy soil, clay soil, light soil or heavy soil.
