Climate and land use effects on hydrologic processes and water allocation in a primarily rain-fed, agricultural watershed
(University of Missouri--Columbia, 2018)
soil and agriculture-dominated land use. It is dominated by high clay content soils, making it sensitive to changes in the hydrologic condition. While numerous studies have examined hydrologic processes around this region, only a few have analyzed...
Manure management using precision agriculture
(University of Missouri--Columbia, 2010)
The overall purpose of this project was to develop and implement a manure application record system that was solely based on Global Positioning Systems (GPS). This system will have the ability to provide steering and ...
Between-row mower design for weed control in organically grown no-till soybeans
(University of Missouri--Columbia, 2018)
Weeds are a major challenge in organic no-till soybean production. They impair crop growth and result in yield loss. Innovative weed control methods need to be developed and experimented with in organic no-till agriculture to reduce weed density...
Climate change impacts on hydrologic components and occurrence of drought in an agricultural watershed
(University of Missouri--Columbia, 2018)
of Goodwater Creek Experimental Watershed (GCEW) and experimental field (Field1) were assessed using climate datasets from the Coupled Model Intercomparison Project Phase 5 (CMIP5), Soil and Water Assessment Tool (SWAT) and Agricultural Policy Environmental...
Predicting switchgrass biomass and ethanol potential on claypan soil landscapes
(University of Missouri--Columbia, 2015)
Switchgrass (Panicum virgatum L.) yield on claypan soils was evaluated with a crop growth model and for actual ethanol production potential. Specifically, Agricultural Land Management Alternatives with Numerical Assessment Criteria (ALMANAC...
Soil property estimation using visible and near-infrared reflectance
(University of Missouri--Columbia, 2012)
Site-specific management of crop production systems holds promise for maintaining high yields while preserving soil quality. This management requires detailed spatial data on soil physical and chemical characteristics but ...
Development of a multispectral sensor for crop canopy temperature measurement
(University of Missouri--Columbia, 2017)
The Multispectral System for Imaging of a Crop Canopy (MSICC) that combines a miniature long wavelength infrared (LWIR) camera with a visible camera was developed to capture a field of view and derive a plant specific ...
Evaluation of a solid-liquid manure separation operation
(University of Missouri--Columbia, 2018)
Field monitoring and laboratory tests were conducted to evaluate the efficacy and practicality of a solid-liquid separation barn for finishing pigs. The solid-liquid separation system included a mechanical scraper and ...
Logistic modeling of a biomass utilization system
(University of Missouri--Columbia, 2009)
A logistic model was developed for a biomass utilization system and implemented in ExtendSim. The model allows for system simulation and analysis of biomass supply chain in terms of economic viability and energy balance. ...
Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)
Automated sensing of soil macronutrients (i.e., N, P, and K) would allow more efficient mapping of soil nutrient variability for variable-rate nutrient management. This study reports on the development of a sensor array ...
Development of an online planning tool for designing terrace layouts
(University of Missouri--Columbia, 2010)
A web-based conservation planning tool for terrace layouts was created by modifying a terrace location program (TERLOC), developed originally by Sudduth and Gregory (1982) and revised by Ghidey et al. (1992). Development ...
Modeling of delayed fluorescence from photosystem II and applications in assessment of drought and chemical stresses
(University of Missouri--Columbia, 2009)
Photosynthesis is not only vital for plant growth and survival but also indicative of plant-environment interactions. This research was designed to analyze photoelectron kinetics and its dependence on environmental factors. ...
Modeling the influence of climate and management practices on water quality in Goodwater Creek experimental watershed
(University of Missouri--Columbia, 2006)
The objective of this study was to determine relationships among weather, runoff, water quality, and best management practice (BMP) implementation in reducing atrazine losses in the 7,250-ha Goodwater Creek Experimental ...
