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 grass+trees (agroforestry...
Soil quality assessment for an alfisol undergoing alternative organic weed management systems
(University of Missouri--Columbia, 2017)
As organic agriculture farmland continues to increase on a global scale with 6.5 million hectares added during 2014-2016, the increased number of organic producers will be expected to fulfill sustainability obligations. However, tillage...
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 the deterioration of soil...
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 Act. This study examined...
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 cover crops, tillage...
Sorption and transport of veterinary antibiotics in agroforestry buffer, grass buffer, and cropland soils
(University of Missouri--Columbia, 2011)
agricultural lands. Sorption experiment results showed that oxytetracycline (OTC) was strongly adsorbed and not readily extractable, while sulfadimethoxine (SDT) and sulfamethazine (SMZ) were highly mobile in soil. For all the antibiotics studied, VBS soils had...
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 ...
Agroforestry and grass buffers for improving soil hydraulic properties and reducing runoff and sediment losses from grazed pastures
(University of Missouri--Columbia, 2009)
that establishment of agroforestry and grass buffers on grazed pasture watersheds improves soil carbon accumulation and root parameters which enhance soil physical and chemical properties, thus improving the environmental quality of the landscape. The Agricultural...
Soil health assessment of the Sanborn Field long-term experimental study
(University of Missouri--Columbia, 2018)
Soil health assessment uses a combination of potential indicators affecting soil processes to comprehensively monitor soil change, caused by cropping systems and soil management. The objectives of the study were to assess ...
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 ...
