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. -
Progressive and Regressive Soil Evolution Phases in the Anthropocene
Progressive and regressive soil evolution phases in the Anthropocene Manon Bajard, Jérôme Poulenard, Pierre Sabatier, Anne-Lise Develle, Charline Giguet- Covex, Jeremy Jacob, Christian Crouzet, Fernand David, Cécile Pignol, Fabien Arnaud Highlights • Lake sediment archives are used to reconstruct past soil evolution. • Erosion is quantified and the sediment geochemistry is compared to current soils. • We observed phases of greater erosion rates than soil formation rates. • These negative soil balance phases are defined as regressive pedogenesis phases. • During the Middle Ages, the erosion of increasingly deep horizons rejuvenated pedogenesis. Abstract Soils have a substantial role in the environment because they provide several ecosystem services such as food supply or carbon storage. Agricultural practices can modify soil properties and soil evolution processes, hence threatening these services. These modifications are poorly studied, and the resilience/adaptation times of soils to disruptions are unknown. Here, we study the evolution of pedogenetic processes and soil evolution phases (progressive or regressive) in response to human-induced erosion from a 4000-year lake sediment sequence (Lake La Thuile, French Alps). Erosion in this small lake catchment in the montane area is quantified from the terrigenous sediments that were trapped in the lake and compared to the soil formation rate. To access this quantification, soil processes evolution are deciphered from soil and sediment geochemistry comparison. Over the last 4000 years, first impacts on soils are recorded at approximately 1600 yr cal. BP, with the erosion of surface horizons exceeding 10 t·km− 2·yr− 1. Increasingly deep horizons were eroded with erosion accentuation during the Higher Middle Ages (1400–850 yr cal. -

In this study, two typical intact sequences of the first paleosol layer (S1) on the southern CLP were selected, and soil hydraulic parameters together with basic physical and chemical properties were investigated to reveal the response of soil hydraulic properties to the warm and wet climate conditions. The results show that: (1) the paleoclimate in the southern CLP during the last interglacial period showed a pattern of three warm and -

Use of Agricultural Soil Maps in Making Soil Surveys
108 USE OF AGRICULTURAL SOIL MAPS IN MAKING SOIL SURVEYS L. D HICKS, Chief Soils Engineer North Oil 'lina State Highway and Pubi Works Commission SYNOPSIS Soil surveys are made to obtain information relative to the type, extent of occurrence, and characteristics of the soils in a given area. The use of the pedological system of classification permits easy identification of the soils as to type, and knowledge of the characteristics of various soil types and previous experience with them can be utilized in planning and design. A large portion of many states has been surveyed by the Department of Agri• culture and maps are available showing the location of the various soil types. These maps may be used as guides in making soil surveys, and in many instances they contain all of the information desired. When agricultural soil maps are not available or when extreme accuracy is necessary, a soil survey must be made. The pedological system of classification can be used in making the survey by anyone with some knowledge of the system, assisted by a soil identification "key". This paper describes the use of agricultural soil maps by the North Carolina State Highway Department and a soil identification key used in making soil sur• veys IS included. The use of the key is described. The first soil surveys in the United suitability for various crops given.

FOR PART II HONS. GEOGRAPHY MODULE 6; UNIT : 1 ; TOPIC : 1.2 Prepared by Dr. Rajashree Dasgupta Asst. Professor, Dept. of Geography Government Girls’ General Degree College, Kolkata -23 4/3/2020 1 INTRODUCTION ZONAL SOILS : Zonal soils are those soils formed along broad zones of the earth. They are very much in conformity with climate and natural vegetation such as Podzol, Chernozem and Laterite soils. They are mature soils i.e. have fully developed soil profiles with distinct horizons (A, B & C). They are very much in equilibrium with environmental conditions. INTRAZONAL SOILS : Intrazonal soils are developed within the zonal soils. Because of certain local factors the type of soil is different from zonal soils eg. Alkali soils, peat soils i.e. hydromorphic soils. Because of heavy deposition of salt, the soil has been different. AZONAL SOILS : Those soils which fail to develop mature soil profiles. These soils develop over flood plains, aeolian deserts, loessic areas, alluvial soils , sketletal soils at the foot of the mountains. They are immatured soils due to lack of time in their soil forming process. 4/3/2020 Dept. of Geography, GGGDC, Kolkata 2 According to Dokuchaev, the classification of soils is as follows Class A : Normal Soils (Zonal Soils ) ZONES SOILS 1. Boreal Tundra 2. Taiga Light Grey podzolised soils 3. Forest Steppe Grey & dark grey soils 4. Steppe Chernozem 5. Desert Steppe Chestnut & Brown Soil 6. Desert Zone Yellow soils and white soils. 7. Subtropical Zones or Laterite & Red Soils Tropical Forest Class B : Transitional Soils (Intrazonal Soils ) Name of the Soils 1. -

Frost Considerations in Highway Pavement Design: West-Central United States
Frost Considerations in Highway Pavement Design: West-Central United States F. C. FREDRICKSON, Assistant Materials and Research Engineer, Minnesota Depart ment of Highways •ASSESSING the harmful effects of frost action on highways and adjusting highway de sign to eliminate the harmful effects is a major effort in frost areas. The problems are roughness resulting from freezing, weakening of road structures on thawing, and the deterioration of materials and structures resulting from freeze-thaw. The number of problems, their seriousness, and the nature of corrective action depend on the se verity of the frost action which is r elated to geographi c location. The area considered in this report includes Arkansas, Oklahoma, Missouri, Kansas, Nebraska, Iowa, South Dakota, North Dakota and Minnesota. GENERAL INFORMATION This area involves regions of diverse climate and topography, ranging from the forest and lake region of northern Minnesota through the vast plains and lowlands to the Ozarks in Missouri and Arkansas. It can generally be subdivided into three phys iographic provinces: the Great Plains, Central Lowlands, and the Ozark Plateau re gion (Fig. 1). The Great Plains region is part of the high Piedmont area located at the foot of the Rockies. Elevations gradually rise from 1, 000 ft in the east to 5, 000 ft in the west. Grazing and winter wheat farming reflect the moisture deficiency of the area. Elevations in the Central Lowlands are fairly uniform ranging from 500 to approxi mately 1, 500 ft. This province, trending north-south through the area, forms the basis for the rich agricultural economy of the Cotton Belt, Corn Belt, and the Spring Wheat regions in the Dakotas. -

land Article Carbon Storage along with Soil Profile: An Example of Soil Chronosequence from the Fluvial Terraces on the Pakua Tableland, Taiwan Chin-Chiang Hsu 1 , Heng Tsai 1,*, Wen-Shu Huang 2 and Shiuh-Tsuen Huang 3 1 Department of Geography, National Changhua University of Education, Changhua 500, Taiwan; [email protected] 2 Center for General Education, National Chung Cheng University, Chiayi 621, Taiwan; [email protected] 3 Department of Science Education and Application, National Taichung University of Education, Taichung 403, Taiwan; [email protected] * Correspondence: [email protected] Abstract: A well-dated soil chronosequence may allow exploration of the accumulation of soil carbon over time. There are multiple levels of river terraces on the Pakua tableland in Central Taiwan. Unlike many of the reddish or lateritic soils in Taiwan, these soils were recently dated, with absolute ages in the range of 19–400 kyr. This information allowed us to develop an ideal soil chronosequence, with time constraints, through which it is possible to explore soil organic carbon (SOC) storage and its changes over time. In this study, we attempted to establish an SOC time series, and to give an estimate of long-term accumulation of the SOC storage in the red soils of Taiwan. The data on these soils used in this study were taken from the soil profiles presented in our previous studies. Two additional soil profiles were sampled for those soils for which data were not available from the Citation: Hsu, C.-C.; Tsai, H.; Huang, previous studies. -
