Sorption, uptake and biotransformation of 17β‐estradiol, 17α‐ethinylestradiol, zeranol and trenbolone acetate by hybrid poplar
Hormonally active compounds may move with agricultural runoff from fields with applied manure and biosolids into surface waters where they pose a threat to human and environmental health. Riparian zone plants could remove hormonally active compounds from agricultural runoff. Therefore, sorption to roots, uptake, translocation, and transformation of three estrogens (17β‐estradiol, ...

A review of vegetated buffers and a meta-analysis of their mitigation efficacy in reducing nonpoint source pollution
Received for publication December 1, 2008. Vegetated buffers are a well-studied and widely used agricultural management practice for reducing nonpoint-source pollution. A wealth of literature provides experimental data on their mitigation efficacy. This paper aggregated many of these results and performed a meta-analysis to quantify the relationships between pollutant removal efficacy and buffer ...

Modeling effect of cover condition and soil type on rotavirus transport in surface flow
Runoff from animal production facilities contains various microbial pathogens which pose a health hazard to both humans and animals. Rotavirus is a frequently detected pathogen in agricultural runoff and the leading cause of death among children around the world. Diarrheal infection caused by rotavirus causes more than two million hospitalizations and death of more than 500,000 children every ...

The manage database: nutrient load and site characteristic updates and runoff concentration data
The 'Measured Annual Nutrient loads from AGricultural Environments' (MANAGE) database was developed to be a readily accessible, easily queried database of site characteristic and field-scale nutrient export data. The original version of MANAGE, which drew heavily from an early 1980s compilation of nutrient export data, created an electronic database with nutrient load data and corresponding site ...

Transition of fertilizer application and agricultural pollution loads: a case study in the Nhue-Day River basin
Rapid socio-economic development in suburban areas of developing countries has induced changes in agricultural waste and nutrient management, resulting in water pollution. The study aimed at estimating agricultural nutrient cycles and their contribution to the water environment. A material flow model of nitrogen (N) and phosphorus (P) was developed focusing on agricultural activities from ...

Pesticide runoff from greenhouse production
A research has been undertaken studying pesticide residues in water from greenhouses and the use of soils and filter materials to reduce such losses. The pesticides detected in water samples collected downstream greenhouses include 9 fungicides, 5 herbicides and 4 insecticides. 10 compounds from flower and vegetable productions were frequently found to exceed environmental risk levels, and with a ...

Rates and product identification for trenbolone acetate metabolite biotransformation under aerobic conditions
Trenbolone acetate (TBA) metabolites are endocrine active contaminants discharged into the aquatic environment in runoff from agricultural fields, rangelands, and concentrated animal feeding operations (CAFOs). To investigate the environmental fate of these compounds and their biotransformation mechanisms, we used inocula from a variety of different water sources and dosed biologically active ...

Agroforestry Buffers Reduce Runoff from Agricultural Watersheds
Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective of this study was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop ...

Worst Water Weeds #3: Duckweed
Duckweed makes our list of worst water weeds because it can be a huge nuisance to ponds and other still water bodies. There are many different species of this flowering floating aquatic plant, most of which are native, but at least one of which is exotic. What they all have in common, however, is that with the right conditions, they can become incredibly invasive and wreak havoc on other native ...

Organic Fertilizer Benefits
Organic Fertilizer Benefits – Why not use synthetic fertilizers? It’s a reasonable question. After all, nitrogen, phosphorus, and potassium ARE chemicals, so where is the advantage in these bags of heavy, grainy stuff, that need to be measured and mixed and then dug in, when you can just pick up a small plastic bottle of the blue stuff? There are several organic fertilizer benefits, ...

Why are we monitoring nutrients at different depths?
Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...
