Assessing Drought Regions and Vulnerability Through Soil Climate Regimes
Assessing Drought Regions and Vulnerability Through Soil Climate Regimes William J. Waltman University of Nebraska, Lincoln, NE 68583-0915., Stephen Goddard, Gang Gu, Stephen E. Reichenbach, Mark D. Svoboda, and Jeffrey S. Peake. Abstract The agricultural landscapes of the Great Plains reflect a complex pattern of soil climate regimes (Soil Taxonomy, Soil Survey Staff, 1999) and inherent variability that influence the cropping systems and behavior of farmers. The historical crop yields and acreage harvested of crops were compared with climatic events through time to describe the trends and adaptations of farmers and changes in agroecology. The USDA National Agricultural Statistics Service and Risk Management Agency's county-level databases were coupled with soil climate regimes derived from the Enhanced Newhall Simulation Model to explain spatial relationships of crop yields and identifying growing environments favorable to corn, soybeans, sorghum, and wheat. In addition, these geospatial databases can be used to characterize shifts in growing environments through time and space. Comparisons were generated at the county level between irrigated and nonirrigated yields, yield ratios (corn:soybean) to identify favored environments, shifts in crop acreages reflecting past climatic events and changes in genetics, and dominant "cause-of-loss" processes for specific crops. The Enhanced Newhall Simulation Model was used to derive probabilities of soil climate regimes and differentiate agroecological zones. This study also addresses the changes in the agroecology and behavior of soil climate regimes in the Great Plains and connections to El Nino/La Nina events. Introduction Drought is the dominant process of crop loss nationally and within Nebraska. As Table 1 illustrates, on a statewide basis for Nebraska, nearly two-thirds of the 18.6 million harvested acres are covered by crop insurance. -

Plant-Water Demand Characteristics in the Alfisol, Zaria Nigeria
Plant-Water demand Characteristics in the Alfisol, Zaria Nigeria Dim, L.A.1 – Odunze, A.C. – Heng, L.K. – Ajuji, S. Centre for Energy Research and Training, Ahmadu Bello University, P M B 1014, Zaria, Nigeria Email: [email protected]; Tel: 08023635501 Corresponding Author’s E-mail: [email protected] Abstract The Nigeria Guinea Savanna zone currently witness increasing intensification of agricultural production activities. The soils are said to have ustic moisture and isohyperthermic temperature regimes implying that rainfalls during the cropping season are limited, irregular or during the dry seasons crop production would be strongly affected by available soil water inadequacy for crop use and production. Supplemental or total water supply by irrigation would therefore be necessary to avert crop failure. Also physical restriction to root elongation can reduce soil water and nutrients uptake as well as plant growth irrespective of water and nutrient supply. This study therefore evaluated soil characteristics and water extraction depth by maize (test crop) in the Northern Guinea Savanna zone Alfisol in Zaria (110 10¹N and 7035¹E) Nigeria. Results show that minimal soil water was extracted by maize at seedling and crop maturity phases, and optimal at crop establishment to grain filling phases. Zone of active soil water extraction shown by the study is 10 to 20 Cm soil depth. Water rather accumulated at the shallow depths of 30 Cm and below following the presence of such sub soil free drainage obstructions as clay and plinthic layers. 1. Introduction Tropical semi-arid regions usually have large variations in physical conditions, both over time (variation in weather among years) and location (climate and edaphic conditions). -

Custom Soil Resource Report for Miami-Dade County Area, Florida
United States A product of the National Custom Soil Resource Department of Cooperative Soil Survey, Agriculture a joint effort of the United Report for States Department of Agriculture and other Federal agencies, State Miami-Dade Natural agencies including the Resources Agricultural Experiment County Area, Conservation Stations, and local Service participants Florida July 12, 2018 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951). -

Late-Quarternary Stratigraphy, Pedology
AN ABSTRACT OF THE THESIS OF Dustin White for the degree of Master of Arts in Interdisciplinary Studies in Anthropology, Geology, and Anthropology presented on May 27, 1998. Title: Late-Quaternary Stratigraphy, Pedology and Paleoclimatic Reconstruction of the Cremer Site (24SW264), South-Central Montana: A Geoarchaeological Case Study. Abstract approved: Redacted for Privacy Robson Bonnichsen This study utilizes a multidisciplinary research approach integrating the sciences of archaeology, geology, pedology and paleoclimatology. Deeply stratified and radiocarbon dated sedimentary sequences spanning the last 10,000 yr B.P. are reported for the Cremer site (24SW264), south-central Montana. Previous investigations at the site revealed an archaeological assemblage with Early Plains Archaic through Late Prehistoric period affiliations. Expanded testing of the site integrates the existing cultural record with new data pertaining to Holocene environmental changes at this northwestern Great Plains locality. Detailed pedological descriptions were made along three trenches excavated at the site. The combined soil-stratigraphic record indicates that distinct intervals of relative landscape stability and soil development occurred at the site at ca. 10,000 yr B.P., 7,500 yr B.P. and intermittently throughout the last ca. 6,000 yr B.P. Periods of significant landscape instability (upland erosion and valley deposition) occurred immediately following each of the early Holocene soil forming intervals identified above, and episodically throughout the middle to late Holocene. The impetus for early Holocene environmental instability is attributed to generally increased aridity on the northwestern Great Plains. Comparative analyses of site data with both regional environmental proxy records and numerical models of past climates (General Circulation and Archaeoclimatic models) are made to test the findings from the Cremer site. -

Soil and Water Relationships of Florida Ecological Communities
One of the documents mentioned in Rule 62-340, F.A.C. is Soil and Water Relationships of Florida’s Ecological Communities by the Florida’s Soil Survey Staff, USDA-NRCS. With their permission we have adapted the document for our website. SOIL AND WATER July, 1992 Adapted RELATIONSHIPS OF FLORIDA’S ECOLOGICAL COMMUNITIES Page 2 SOIL AND WATER July, 1992 Adapted RELATIONSHIPS OF FLORIDA’S ECOLOGICAL COMMUNITIES Contents Page Ecological Communities of Florida 1 Field Identification of Ecological Communities 3 Hydric Soils of Florida 9 Field Identification of Hydric Soils 10 Hydric Soil Indicators: Indicator and User Notes 12 Estimating the Seasonal High Water Table 20 References 22 Forward: This material has been produced and is provided by Florida Soil Conservation Service Soil Survey Staff, G. Wade Hurt, State Soil Scientist, in consultation with soil scientists from other agencies as well as the private sector. The sections Field Identification of Hydric Soils, Hydric Soil Indicator, and Estimating the Seasonal High Water Table have been updated by Florida Department of Environmental Protection Submerged Lands and Environmental Resources Coordination staff in accordance with the Field Indicators of Hydric Soils in the United States, Version 7.0. The purpose of this material is to present an understanding of soil and water relationships by soil scientists in Florida and to promote an appreciation and understanding of these soil and water relationships among others. The ecological community concept is used because only after a thorough understanding of natural systems such as ecological communities can we understand the implication of any soil attribute such as the water table to any proposed land use change.
