Interacting Processes in Soil Science focuses on coupled processes in soil. Topics covered in this important volume include the effects of inorganic salts upon water flow, modeling of sorption, transport and transformation of organic solutes, and the effects of microorganisms on silicate clay minerals. The book presents studies and approaches that can be extended and complemented by innovative work in the future. Interacting Processes in Soil Science will be an essential reference for all researchers and students in soil science, soil and water engineering, civil and environmental engineering, earth sciences, and hydrology.
The 1939-45 war forced the Allied countries to seek alternative sources of raw materials and, as in the First World War, attention was paid by all belligerents to the marine algae or seaweeds. These occur in considerable quantities in various parts of the world, and attempts to make use of this cheap and readily accessible, though not so readily harvestable, raw material have been made almost from time immemorial. Much of the work on the economic utilization of seaweeds has been published only in scientific journals and has never been collected within the compass of a single book. Tressler's work on The Marine Products of Commerce contains three useful chapters on this subject, whilst Sauvageau's book, Les utilisations des Algues Marines, is a mine of valuable information, especially as regards the use of seaweeds in France. Both these volumes are, however, somewhat out of date, Tressler's being published in 1923 and Sauvageau's in 1920. Furthermore there is no book wholly on this subject in the English language, and so the present volume has been undertaken in order to fill this gap. The opportunity has also been taken to incorporate the results of researches carried out since 1920. In certain aspects of the subject it will be found that considerable advances have been made, and in the present volume particular reference to such advances will be found in the chapters on agar and alginic acid.
The book contains the contributions at the NATO Study Institute on Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology, which took place in Sofia – Borovetz, Bulgaria, July 1–10, 2008. Rapid advances in mathematics, computer science and molecular biology and chemistry have lead to the development in of a new branch of toxicology called Computational Toxicology. This emerging field is addressing the estimation and prediction of exposure risk and effects of chemicals based on experimental data, measured concentration and biological mechanisms and computational models of biological systems. Mathematical models are also being used to predict the fate and transport of substances in the environment. Because this area is still in its infancy, there has been limited application from governmental agencies to regulating controllable processes, such as registration of new chemicals, determination of estimated exposure and risk based limits and maximum acceptable concentrations in different compartments of the environment – ambient air, waters, soil and food products. However, this is soon to change as the ability to collect, analyze and interpret the required information is becoming increasingly more efficient and cost effective. Full implementation of the new processes have to involve education on both part of the experimentalists who are generating the data and the models, and the risk assessors who will use them to better protect human health and the environment.
Precision Agriculture is becoming ever more relevant as the agricultural industry struggles to come to terms with the environment, economics, traceability, vehicle guidance and crop management. Whilst some benefits have proved elusive, others contribute positively to today’s agriculture. Research continues to be necessary and needs to be reported and disseminated to a wide audience. These proceedings contain the reviewed papers from the 7th European Conference on Precision Agriculture. The papers reflect the wide range of disciplines that impinge upon precision agriculture including remote sensing, plant disease and weed detection, yield monitoring, soil sensing, geo statistics and path planning, regional and crop modelling, cooperation and guidance of robots, precision application, ICT in precision agriculture, future farming and European relevance for precision agriculture. The broad range of research topics reported is a valuable resource for researchers, advisors, teachers and professionals in agriculture. Also note that the reviewed papers from the 4th European Conference on Precision Livestock Farming are presented in a companion publication.
Volume 74 contains six excellent cutting-edge reviews detailing advances in the plant and environmental soil sciences. Chapter 1 is an extensive review on soil quality. Chapter 2 covers recent advances in understanding the formation of metal hydroxide precipitates on soil surfaces and their implications on metal sequestration and soil remediation. Chapter 3 is a timely review on effects of organic acid exudation from roots on phosphorus uptake and aluminum tolerance of plants in acid soils. Chapter 4 discusses bamboo production and management, including manipulation of growth and development and environmental aspects of bamboo production. Chapter 5 addresses a significant worldwide issue - management of soils for food security and environmental quality. Chapter 6 is a comprehensive review on the management of wheat, barley, and oat root systems.
