This book was released on 2015 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important cause of freshwater contamination in the United States, soluble reactive phosphorus (SRP) loss from agriculture often occurs when overland runoff transports phosphorus (P) from manures and fertilizers to receiving waters. Because of the importance of overland runoff in transporting P, models that allow us to pinpoint the location and timing of overland runoff are an important tool for reducing SRP transport in overland runoff. We created a simple regional model that allows us to predict the timing and location of runoff in the northeastern United States. In addition, we conducted soil box experiments which indicate that SRP concentrations decline rapidly over time after manure fertilization, and this decline in P availability is affected by temperature. We developed an SRP model which predicts the SRP concentration after manure application, which, combined with the spatially explicit watershed model, allows for prediction of SRP loss from agriculture under a variety of manure timing scenarios. We find that in a 326 km2 watershed where farmers apply P to match crop needs, simply changing the timing of manure application to avoid periods of runoff have the potential to reduce manure-derived SRP in runoff by up to 40%. iii.

Download or read book Modeling Chemical Transport in Soils written by Hossein Ghadiri and published by CRC Press. This book was released on 1992-09-23 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling Chemical Transport in Soils: Natural and Applied Contaminants provides a comprehensive discussion of mathematical models used to anticipate and predict the consequences and fate of natural and applied chemicals. The book evaluates the strengths, weaknesses, and possibilities for application of numerous models used throughout the world. It examines the theoretical support and need for experimental calibration for each model. The book also reviews world literature to discuss such topics as the movement of sorbed chemicals by soil erosion, the movement of reactive and nonreactive chemicals in the subsurface and groundwater, and salt transport in the landscape. Modeling Chemical Transport in Soils: Natural and Applied Contaminants is an important volume for environmental scientists, agricultural engineers, regulatory personnel, farm managers, consultants, and the chemical industry.

MODELLING SOIL EROSION BY WATER l 2 John Boardman and David Favis-Mortlock 1 School of Geography and Environmental Change Unit Mansfield Road University of Oxford Oxford OX1 3TB UK 2 Environmental Change Unit University of Oxford 5 South Parks Road Oxford OX1 3UB UK Introduction This volume is the Proceedings of the NATO Advanced Research Workshop 'Global Change: Modelling Soil Erosion by Water', which was held on II-14th September 1995, at the University of Oxford, UK. The meeting was also one of a series organised by the IGBP 1 GCTE Soil Erosion Network, which is a component of GCTE's Land Degradation Task (3.3.2) (Ingram et aI., 1996; Valentin, this volume). One aim of the GCTE Soil Erosion Network is to evaluate the suitability of existing soil erosion models for predicting the possible impacts of global change upon soil erosion. Due to the wide range of erosion models currently, in use or under development, it was decided to evaluate models in the following sequence Favis-Mortlock et al., 1996): • field-scale water erosion models • catchmenr-scale water erosion models • wind erosion models • models with a landscape-scale and larger focus. As part of this strategy, the first stage of the GCTE validation of field-scale erosion models was carried out at the Oxford NATO-ARW. I A list of Acronyms fonns Appendix A.

Book excerpt: Despite advances in modeling, such as graphical user interfaces, the use of GIS layers, and databases for developing input files, the approaches to modeling phosphorus (P) have not changed since their initial development in the 1980s. Current understanding of P processes has evolved and this new information needs to be incorporated into the current
