Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soil hydraulic properties and plant-available water (PAW) capacity are critical properties in evaluating land management and soil productivity. This ...
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
Knowledge of neonicotinoid sorption and transport in soil is crucial to understanding environmental risk associated with the most widely used class of insecticides. To determine mobility and transport of the neonicotinoid ...
Assessing impacts and targeting of agricultural conservation practices
(University of Missouri--Columbia, 2010)
The U.S. Department of Agriculture initiated the Conservation Effects Assessment Project in 2003 to quantify water quality and wildlife benefits of conservation programs funded by the 2002 Farm Security and Rural Investment ...
Agroforestry and grass buffers for improving soil hydraulic properties and reducing runoff and sediment losses from grazed pastures
(University of Missouri--Columbia, 2009)
Agroforestry buffers, a system of land use in which harvestable trees or shrubs are grown among or around crops or on pastureland, have been proposed for improving water quality in watersheds. The objectives of this study ...
Soil quality as affected by agroforestry and grass buffers in grazed pasture and row crop systems
(University of Missouri--Columbia, 2011)
Establishment of agroforestry and grass buffers within agroecosystems is believed to improve soil quality. Soil enzyme activities and water stable aggregates have been identified as sensitive soil quality indicators to ...
Apex and fuzzy model assessment of environmental benefits of agroforestry buffers for claypan soils
(University of Missouri--Columbia, 2013)
Contamination of surface waters with pollutants from agricultural land is a major threat to the environment. A field-size watershed study in Northeast Missouri showed that vegetated filter strips containing grass and ...
Soil hydraulic and physical properties as affected by logging management
(University of Missouri--Columbia, 2014)
Former studies have shown that once compacted, forest soils often recover slowly (many decades) to pre-disturbed levels for soil properties such as bulk density or penetrometer resistance. Runoff and soil erosion from ...
Enhanced rhizodegradation of munitions explosives and degradates by selected native grass species
(University of Missouri--Columbia, 2010)
TNT (2,4,6-trinitrotoluene) and RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) are the two most widespread explosives in the world. The manufacture, use and disposal of explosives can result in environmental contamination, ...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
Water and soil are two key elements for life on this planet, and improving and preserving their quality are of prime importance. Various human actions including use of intensive chemicals in agriculture have accelerated ...
Sorption and transport of veterinary antibiotics in agroforestry buffer, grass buffer, and cropland soils
(University of Missouri--Columbia, 2011)
Understanding sorption and transport of veterinary antibiotics (VAs) is important for assessing the risk of VAs reaching water resources. Vegetative buffer strips (VBS) may be a useful tool for mitigating veterinary ...
Influence of agroforestry buffers on soil hydraulic properties relative to row crop management
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Agroforestry (AgB) and grass (GB) buffers have been developed as a part of the management system for row crop areas in temperate regions to improve ...
Long-term soil and crop management effects on soil physical properties related to soil erodibility
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Long-term soil and cropping systems affect soil physical properties thereby effecting soil erosion and erodibility. Understanding the effects of crop ...
Water infiltration and soil water content in claypan soils influenced by agroforestry and grass buffers compared to row crop management
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The effects of agroforestry and grass-legume buffers on in situ water infiltration relative to row crop management (RC) were assessed for a claypan ...
Soil physical and hydraulic properties affected by topsoil thickness in switchgrass and row crop management systems /
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Degraded claypan landscapes can be seen as a potential resource for bioenergy production. Therefore, an important decision needs to be made to determine ...
Influence of cover crop and tillage management practices on soil physical and hydraulic properties
(University of Missouri--Columbia, 2017)
Several agricultural land management practices, such as cover crops and tillage, can influence soil physical and hydraulic properties, soil health indicators and crop productivity. This study evaluated the influence of ...
