Irrigation and Drainage, EarlyView.ABSTRACT The study focused on modelling open channel flow in an agricultural ditch network. The objectives were (1) to set up a computational tool to explore the hydraulic impacts of water level control in a collector ditch network and (2) to test the effects of damming height and ditch flow resistance on the water level and its relation to field ...

A chemical survey of standing waters in south-east England, with reference to acidification and eutrophication [PDF]
, 1997 This study looks at the distribution and magnitude of acidification and eutrophication in south-east England where there are no natural lakes but a large number of shallow artificial ponds.

Phosphorus fractions status of representative agricultural fields in North Carolina
Journal of Environmental Quality, EarlyView.Abstract Most agricultural soils in North Carolina have high levels of available phosphorus (P), yet little is known about other accumulated P fractions and their associated environmental risks. This study characterized soil P fractions through sequential chemical fractionation of 391 samples (0–10 cm and 10–20 cm) collected from 57 counties across ...

Shallow‐lake sediments release nutrients by complete destratification events
Journal of Environmental Quality, EarlyView.Abstract The development of phytoplankton communities in hypereutrophic shallow lakes, often used for aquaculture, is not fully understood and can sometimes be unpredictable. Focusing on the abiotic factors that regulate their succession, we recorded short‐term mixing events in a shallow lake and examined their relationship with nutrient release from ...

Analysis of Mathematics and Sustainability in an Impulsive Eutrophication Controlling System
Abstract and Applied Analysis, 2013 Eutrophication removal problems have captured the attention of biologists, mathematicians, and environmental scientists. Within this framework, an impulsive eutrophication controlling system is studied analytically and numerically. A key advantage of the

Life cycle analysis for the cultivation and combustion of miscanthus for biofuel compared with natural gas [PDF]
, 2008 As negative environmental and economic impacts of fossil fuels have escalated, so has the importance of renewable bioenergy crops whose feedstocks are noncompetitive with food supplies. Compared with fossil fuels, use of lignocellulosic feedstocks offers

Development, Efficiency, and Impact Factors of Phosphorus Nanofertilizers in Agriculture: A Review
Journal of Plant Nutrition and Soil Science, EarlyView.Overview of the potential benefits of phosphorus nanofertilizers in agriculture. ABSTRACT Modern intensive agriculture to feed the growing population of the world has been practiced in view of the limitations of arable land and water resources. However, overapplication of chemical fertilizers may pose severe environmental impacts, including soil ...
