Influence of soil pH on cotton morphology, lint yield and lint quality
(2021-07)
The influence of commodity prices has led to an increase in cotton production in Oklahoma over the past decade. With this increase in production there has been growing interest in growing cotton in fields that have been ...
Evaluation of Lime Pretreatment for Cementitious Stabilization of High Plasticity Soil
(Oklahoma State University, 2010-12-01)
This research covers the effects of CKD, fly ash, lime and CKD, and lime and fly ash on a high plasticity soil. Three percentages of CKD and fly ash along with a single percentage of lime with a percentage of CKD and fly ...
Quantitative phytolith analysis: The key to understanding buried soils and to reconstructing paleoenvironments
(2010-05)
Scope and Method of Study: The purpose of this study is to quantitatively recover and analyze the phytoliths from modern and prehistoric prairie soils, and to use the resulting phytolith signatures to develop a better ...
Electrical Conductivity and Sodium Adsorption Ratio Changes Following Annual Applications of Animal Manure Amendments
(Oklahoma State University, 2004-12-01)
The objective of this research was to evaluate the effect of five annual applications of animal manures on soil electrical conductivity (EC) and sodium adsorption ratio (SAR) estimated from saturated soil-paste extracts. ...
Comparing Soil and Hydrological Conditions of Wetlands Reserve Program Restorations and Natural Wetlands Along the Deep Fork River, Oklahoma (Usa)
(Oklahoma State University, 2011-05-01)
Wetlands Reserve Program (WRP) wetland restorations were compared to natural wetlands using hydrological and soil features to determine if WRP wetlands were similar to natural wetlands along the Deep Fork River in central ...
Influence of switchgrass management on soil microbial biomass and fatty acid methyl ester content in soil
(2020-07)
Switchgrass is a fairly new source of commercial biofuel feedstock. Its production can potentially preserve soil health and microbial functions in ecosystems. There is an increasing demand for large scale biomass production, ...
Evaluation of management strategies for continuous forage production in central Oklahoma
(2021-12)
Forage production in the southern Great Plains is an important aspect of the agricultural industry because forage is used to feed livestock that produce many agricultural products that are consumed. A goal of agricultural ...
Suitability of elutriation for the extraction of microplastics from natural soils
(2022-12)
Microplastics are a class of emerging contaminant which pose serious risks to the health and safety of terrestrial and marine ecosystems. Much research has been conducted regarding the prevalence of microplastics in marine ...
Soil nitrogen storage and mineralization potential in a winter wheat system under long-term nitrogen fertilization
(2022-05)
In winter wheat systems, crop nitrogen(N) uptake is sourced primarily from inorganic N fertilization and N mineralization from soil organic matter(SOM). N mineralization is a dynamic N cycling process that relies on many ...
Investigating scale, rainfall-runoff sequences and BMP effects on phosphorus, runoff and sediment yield
(2004-12)
Scope and Methods of Study: 1) Scale effects on phosphorus (P) loss and runoff depth from pastures were investigated by summarizing water quality data from 19 research projects. Spatial (area) and temporal (days after ...
