Evidence Of Variable Climate And Resources During The Late Pleistocene And Holocene At Gona, Ethiopia, Marie White
Evidence Of Variable Climate And Resources During The Late Pleistocene And Holocene At Gona, Ethiopia, Marie White
Steeplechase: An ORCA Student Journal
The African Humid Period (AHP) spanned a period of approximately 15 to 5 thousand years ago (ka) and resulted in Northern and Eastern Africa being wetter than today. This climate change event impacted flora, fauna, and humans to an unknown extent. Much of the work on the AHP across Eastern Africa utilizes lacustrine and marine proxies rather than river-based (fluvial). Gona, located in the Afar region of Ethiopia, is known for its extensive archaeological and fossil records in fluvial deposits. However, the paleoenvironment of the AHP at Gona has not been investigated. This study uses stratigraphy, geochronology, and paleopedology to …

Spatial Variability Of Manganese Oxide In Two Soilscapes: Upland-Lowland, And Riparian Buffer-Wetland Boundary- Wetland, Benjamin Onweni, Richard Griffin, Robert Thomas, Edward Timms, Javon Polk, Annette James
Spatial Variability Of Manganese Oxide In Two Soilscapes: Upland-Lowland, And Riparian Buffer-Wetland Boundary- Wetland, Benjamin Onweni, Richard Griffin, Robert Thomas, Edward Timms, Javon Polk, Annette James
Pursue: Undergraduate Research Journal
Background: This research project describes the development
of a quantitative measurement methodology to determine the
concentration of manganese oxide (MnOx) in two soilscape
positions (Upland- Lowland and Riparian Buffer-Wetland
Boundary-Wetland). Methods: A reaction between the MnOx
in the soil sample and hydrogen peroxide (H2O2) was initiated
to determine the level of MnOx reactivity in the soil sample. Data
was collected from four sites on Soilscape 1 (Upland, Lowland,
and two sites between the Uplands and Lowlands); within each
site, five soil profile depths and three sample replicates were
measured which comprised a total of 60 samples. Additionally,
data was collected …
Characterization Of Claypan Soils In Southeastern Kansas, M. A. Mathis Ii, S. E. Tucker-Kulesza, G. F. Sassenrath
Characterization Of Claypan Soils In Southeastern Kansas, M. A. Mathis Ii, S. E. Tucker-Kulesza, G. F. Sassenrath
Kansas Agricultural Experiment Station Research Reports
Soil erosion reduces topsoil depth. In areas with a claypan, removal of productive topsoil reduces crop yield where the claypan layer is near the surface. The topsoil and claypan layer each have unique characteristics that impact crop production and within-field variability. To better understand these differences, the soil from an area of low crop yield and high crop yield were collected and laboratory tests were performed to determine the soil classification and undrained shear strength. Understanding the soil properties and the interaction between the topsoil and claypan layers may aid in understanding the process by which topsoil is being eroded.

Changes In Soil Microbiology Under Conventional And No-Till Production During Crop Rotation, C. J. Hsiao, G. F. Sassenrath, L. Zeglin, G. Hettiarachchi, C. Rice
Kansas Agricultural Experiment Station Research Reports
Soil microbial activity is important for crop production. Soil microbes are involved in nutrient and water cycling within the soil, and interact with crop plants to provide the basic nutrient and water resources needed for crop production. Claypan soils have unique physical characteristics that impact soil biology. This study explored the temporal changes in soil microbiology in a claypan soil under conventional and no-till production during a crop rotation of corn/winter wheat/soybean/fallow commonly planted in southeast Kansas. We found soil microbial activity changed more in the top two inches of soil than in the lower soil layers. Wheat resulted in …
Correlation Between Mehlich-3 And Ammonium Acetate Extractable Potassium In Kansas Soils, B. Rutter, D. A. Ruiz Diaz
Correlation Between Mehlich-3 And Ammonium Acetate Extractable Potassium In Kansas Soils, B. Rutter, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
The K-State Research and Extension Soil Testing Laboratory has been using Mehlich-3 soil test procedures for phosphorus (P) extraction, and ammonium acetate extraction for potassium (K). Previous research in other states has shown a strong correlation between these two tests for K, but data correlating the two in Kansas soils have been limited. A study was performed on soils from across the state to investigate the relationship between these two methods. A strong positive correlation was observed (r = 0.99) across the wide range of soil types, pH, and fertility conditions represented in the sample set. Linear regression suggests a …
Correlation Of Sikora And Smith-Mclean- Pratt Soil Buffer Ph Measurements, B. Rutter, D. A. Ruiz Diaz, J. Thomas
Correlation Of Sikora And Smith-Mclean- Pratt Soil Buffer Ph Measurements, B. Rutter, D. A. Ruiz Diaz, J. Thomas
Kansas Agricultural Experiment Station Research Reports
Historically, the K-State Research and Extension Soil Testing Laboratory has used the Smith-McLean-Pratt (SMP) buffer solution to estimate total soil acidity and estimate lime recommendations. The SMP solution contains hazardous chemicals and poses a health risk to lab workers. The Sikora buffer solution was designed as a replacement for SMP and contains no hazardous chemicals. A study was conducted to investigate the relationship between these two buffers in Kansas soils. A strong positive correlation was observed between SMP and Sikora buffer pH measurements. However, linear regression suggests that the relationship is not 1:1 (slope = 0.88). Therefore recommendation equations using …
