Organic fertiliser refers to materials used as fertiliser that occur regularly in nature, usually as a by product or end product of a naturally occurring process. Organic fertilisers such as manure have been used in agriculture for thousands of years; ancient farmers did not understand the chemistry involved, but they did recognise the benefit of providing their crops with organic material. Interest in organic farming is growing world-wide as sustainable agricultural practice nowadays. Organic fertilisers are sustained sources of nutrients due to slow release during decomposition. By increasing soil organic matter, organic farming can reinstate the natural fertility of the damaged soil, which will improve the crop productivity to feed the growing population. Organic fertilisers enhance the natural soil processes, which have long-term effects on soil fertility. The book is a very valuable compilation in this direction.
Over the last couple of decades, rapid urbanisation, unplanned industrialisation, and a rising population jointly created several issues worldwide, particularly in developing and underdeveloped countries. One such issue that requires urgent attention is the ever-increasing waste problem which has become an exasperation for regional and local governments and an issue of both national and international importance. Waste in any form and character are the byproduct of anthropogenic activities. To move forward towards a cleaner and greener future, we need to deduce sustainable technologies -- to reduce, reuse and recycle our waste. This book includes important information and views on new developments of waste management technologies, especially from developing and underdeveloped countries. In this book, there are contributions of experts from different countries. Each one of them shows interesting research outputs on waste management technologies which are both economical and eco-friendly; and if applied properly, can lead us towards a 'zero-waste' world.
Designed for undergraduate courses in civil engineering and construction materials and for practicing professional engineers. Also serves as an excellent resource in upper level concrete materials courses. The text provides a cohesive presentation of practical applications supported by detailed background information.
Exploring the dramatic growth and changes in the field of vermicomposting since 1988, this comprehensive review assesses the advancements made in government-funded projects in the U.S. and UK. It discusses outdoor and indoor windrows, container systems, wedge systems, and low labor-requirements. It also examines fully-automated continuous flow vermicomposting reactor systems that can process more than 1000 tons of organic wastes per reactor. The book highlights the science and biology behind the use and efficacy of vermicomposting and details the technology of the past, present, and future.
A rapidly growing population, industrialization, modernization, luxury life style, and overall urbanization are associated with the generation of enhanced wastes. The inadequate management of the ever-growing amount of waste has degraded the quality of the natural resources on a regional, state, and country basis, and consequently threatens public health as well as global environmental security. Therefore, there is an existent demand for the improvement of sustainable, efficient, and low-cost technologies to monitor and properly manage the huge quantities of waste and convert these wastes into energy sources. Innovative Waste Management Technologies for Sustainable Development is an essentia...
Bioinstrumentation deals with the instrumentation techniquesand principles used for measuring physical, physiological,biochemical and biological factors in man or other livingorganisms. This book provides a comprehensive knowledgeabout the basic principles and applications of the tools andtechniques generally used in biology and also those used in thegrowing field of molecular biology. This book will prove to be adependable reference book for students and teachers ofbiological sciences.
Phytomedicine has become more important and gained constant improvement today for the betterment of health. Herbal medicine plays a significant role in the development of new drugs, contrary to the modern medicinal systems. For more than a decade, there has been a drastic improvement in phytomedicine across the world. This growth has reached a higher level in development by pharmaceutical industries everywhere. People have drifted toward herbal medication and practices for their food and health care. Therefore, in order to create abundant interest in the research of phytosciences, this book is one of the better reference tools. The bioactive compounds in plants need to be explored to know th...
Parliamentarians have many responsibilities, both in the legislative chamber and in their constituencies. From participating in house and committee deliberations, to proposing legislation or amendments to other proposed bills, and speaking on behalf of and defending the interests of their electors, parliamentarians are supported by the resources of the body that administers parliament. In the digital era, these resources usually include information and communication technologies (ICTs) that facilitate these important and challenging tasks and support parliamentary transparency and legislative functions. However, little is known about how parliamentarians currently use ICTs to accomplish thei...
A revolution is unfolding in vermiculture studies (rearing of useful earthworms species) for multiple uses in environmental protection and sustainable development. The global scientific community is searching for a technology which should be 'economically cheaper' (to be afforded by all nations), 'environmentally sustainable' (friendly to the environment) and 'socially acceptable' (beneficial to the society). Vermiculture Biotechnology with the use of earthworms combines all these virtues together. Vermiculture (rearing of earthworms) is a 'big business' today and they are also helping in 'employment generation' and 'poverty eradication programs' in several developing countries. This book reviews research on earthworms and how they promise to provide cheaper solutions to several social, economic and environmental problems of human society.
