Biological Phosphorus Solubilisation in Riparian Vegetated Buffer Strip Soils.
… P transfer by establishing riparian 'vegetated buffer strips' is becoming increasingly popular, as they have been shown to reduce total P delivery to streams. However, an uncertainty remains about how buffer strips alter the delivery of dissolved forms of P, which may be highly bioavailable to …

Use of Natural Vegetative Barriers to Limit Black-Tailed Prairie Dog Town Expansion in Western South Dakota
… objectives. Use of naturally occurring buffer strips as vegetative barriers may be effective in limiting prairie dog town expansion. Objectives of this study were to evaluate effective width of vegetative barriers in limiting prairie dog town expansion, document characteristics of …

Using palm-mat geotextiles for soil conservation on arable loamy sands in the United Kingdom
… grass, Borassus completely-cover, Borassus buffer strip and Buriti buffer strip). Using Borassus buffer strips (area coverage ~10%) on bare soil decreased runoff by ~71% (P>0.05) and soil erosion by ~92% (P<0.001). Borassus buffer strip, Buriti buffer strip and Borassus completely-covered …

Best Management Practice Use and Efficacy for the Virginia Nursery and Greenhouse Industry
… supporting selected water-related BMPs (grass buffer strips, CRFs, and irrigation optimization BMPs). Providing the science supporting BMP use gives growers confidence in implementing BMPs to limit water contamination, and prevent waste.

ATTRACTING BENEFICIAL INSECTS TO YOUR FARM: A COMPARISON OF HABITAT MODIFICATION STRATEGIES
… was conducted of 1) managing field margins 2) buffer strips 3) implementing diverse patchy landscapes and 4) native plantings. For each technique, studies are examined based on their efficacy of attracting and sustaining the health of predators and parasitoids of agricultural pests and both …

A model for predicting bacteria concentrations in runoff from agricultural lands
… implementing such BMPs as waste storage, filter strips, and incorporation of manure into the soil can be compared. Data and information collected from the Owl Run watershed in Fauquier County, Virginia is used to demonstrate the model applicability and potential. Long-term manure storage is …

Assessing Potential Solutions to Mitigate Pollution from Neonicotinoid Seed Coatings
… covers used as cover crops or edge-of-field buffer strips, as well as the partitioning of thiamethoxam and clothianidin throughout the plants. Ground covers, such as crimson clover, had the highest recovery of applied thiamethoxam, meaning that it may be a good candidate to retain this …

Land tenure, agri-environmental policy, and conservation practice use in Iowa
… conservation practices. I find that cover crops, buffer strips, and ponds/sediment basins are used at lower rates on rented farmland than on owner-operated farmland. However, no-till is used at a higher rate on rented farmland compared to owner-operated farmland. I also find that non-operator …

Modelling steroidal hormone transport and evaluating best management practices in New Zealand dairy farming systems
… including constructed wetlands, riparian buffer strips, grazing management, and effluent application timing management. All BMPs reduced estrogen and sediment delivery to some degree, but their performance varied. Constructed wetlands placed at critical drainage points showed the greatest …

The Environmental Fate and transport of Trenbolone Acetate Metabolites in Agro-Ecosystems
… was continuously applied to 3-5 m vegetative buffer strips, and ~80% removal was observed. While >97% removal was expected based on equilibrium partitioning, colloid facilitated transport and non-equilibrium conditions likely limited removal. Based on these data, concentrations in runoff from …

Quantifying the Impact of Climate Change on Water Availability and Water Quality in the Chesapeake Bay Watershed
… We select and evaluate four common BMPs (buffer strips, strip crop, no-till, and tile drainage) to test their response to climate change. We force the calibrated model with six downscaled global climate models (GCMs) for a historic period (1990-2014) and two future scenario periods …

Environmental tradeoffs of denitrifying woodchip bioreactors
… drainage water management systems, and riparian buffer strips for treating agricultural drainage water are continually being developed and implemented across the Midwestern United States. Like drainage, bioreactors may have the potential to produce additional environmental and health problems. …

Degradation and transport of veterinary antibiotics and estrogens in a vegetated buffer strip system
… to surface or groundwater resources. Vegetative buffer strips (VBS) affect soil properties that enhance the removal of organic pollutants and thus may be a useful tool for mitigating VA and estrogen transport from agricultural lands. Native warm-season grasses used in VBS have shown to enhance …

Evaluating Agricultural Best Management Practices to Mitigate Neonicotinoid Transport in Water and Soil
… winter cover crops and different edge-of-field buffer strip plant types on movement of the neonicotinoid thiamethoxam (TMX) and its metabolite clothianidin (CLO) in treated agricultural fields. Due to dry weather and other complications, runoff and leachate data could not be statistically …

Evaluating the Two-Stage Ditch as a New Best Management Practice
… good vegetation establishment, with only the buffer strip mix plots (that included grasses mainly designed for use in upland buffer strips) showing a statistically significant lower vegetation coverage when compared to the other four mixes. The buffer strip mix plots were also outcompeted by …
