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 ... -
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 ... -
Assessing the role of probiotics for the enhancement of soil quality under cover crops
(University of Missouri--Columbia, 2015)Use of agro-chemicals over the past few decades has increased land productivity, however, frequent use of agro-chemicals may result in some negative impacts on the environment and soil microbial biodiversity. Use of ... -
The assessment of soil enzyme activities in multiple land use in Central Kalimantan, Indonesia
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Peat swamp forest is one of the most important ecosystems in Southeast Asia, particularly in Indonesia. Tropical peat swamp forests contain a high ... -
Cover crop effects on corn plant water uptake and soil health
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cover crops (CC), close growing crops that provide soil and seeding protection between periods of normal cash crop production or between trees in ... -
Cover crops : an alternative practice to improve soil physical properties and soil water dynamics
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cover crop management practices have emerged in the past decades as an alternative to improve soil physical, biological and chemical properties by ... -
Groundwater nitrogen and phosphorus dynamics under cattle grazing and row crop management in two contrasting soils in Missouri
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nutrient pollution of water resources has been a major environmental problem for decades. Excessive use of chemical fertilizer and livestock management ... -
Soil hydraulic properties as influenced by prairie restoration
(University of Missouri--Columbia, 2015)Prairies are complex living systems which play a vital role both biologically and ecologically in the environment and support a large amount of wildlife. Prairie restoration is an ecologically friendly way to restore prairie ... -
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 ...
