DOWNLOAD EBOOKOrganic waste composting is another excellent example to demonstrate the power and the benefits of nexus thinking. Even though organic waste composting itself is not a new topic, those who want to start a new project or align an ongoing project with nexus thinking, find it difficult to gather the necessary information. With nine case studies from four continents, this book aims to fill above gap in literature. While current literature on composting is often found to be limited to either soil/agriculture sector or waste management sector, this book presents a combined point of view. This open access book starts with an introductory chapter that describes the need to bring the waste management aspects and soil nutrient management aspects of compost production into one integrated theme. The relevance of nexus thinking and the Sustainable Development Goals (SDGs) are also presented in this introduction. The first three chapters after the introduction covers composting from the solid waste management and its policy aspects, taking examples from three developing countries. The next three examples are mostly about the benefits composting can provide to the soil and agriculture. These examples are also from three developing countries, but with a mixture of urban as well as rural settings. Last three chapters present more insight into the latest developments taking examples from Europe, as well as new methods adapted from the traditional styles from Africa.

DOWNLOAD EBOOKThe dramatic worldwide increase in agricultural and industrial productivity has created severe environmental problems. Soil and groundwater reservoirs have been polluted with pesticides, xenobiotics and agro-chemicals. The global consensus to reduce inputs of chemical pesticides and agrochemical fertilizers, which are perceived at being hazardous by some consumers, has provided opportunities for the development of novel, benign sustainable crop management strategies. The future of agricultural depends upon our ability to enhance the productivity without damage to their long-term production potential. One of the strategies is the application of effective microbial products beneficial for both farmers and ecosystems. This kind of approach can ensure both ecological and economic sustainability. Soil microbial populations are immersed in framework of interactions, which are known to affect plant fitness and soil quality. For betterment of life of human being, improved quality and variety of products are formed due to versatile action of different group of microorganisms, Microbes are able to degrade solid waste material into compost which is a mixture of decayed organic matter, manure etc. Incomplete microbial degradation of organic waste where the microbial process varies aerobic to anaerobic form is stated as compost, if added to soil improves plant growth and development. The biological activities and microbial metabolism in the soil contribute to alter its mixture and fertility. Incorporation of organic remain in the form of compost is known to influence favourably the physio-chemical and biological properties of soil. The beneficial activities bestowed upon plants by compost utilization are multifaceted, hence most promising alternatives for achieving sustainable agricultural production. An increased awareness on compost has led to their use in agricultural concern. Contents in the present book will comprised various chapters on the role of beneficial bacteria in the composting process. The application is depicted to achieve the attainable productivity besides, in disease management and suppressiveness of organisms of phytopathogenic in nature. Significance of the compost elicits certain responses e.g. soil reclamation, soil fertility, soil health and disease management exhibit due to quality compost amendment in soil. It serves as low cost prospective option for sustainable crop production and protection.

DOWNLOAD EBOOKSoil enzymes play a fundamental role in many soil processes such as the mineralization of organic matter, the synthesis of humic substances, the degradation of xenobiotics or the mechanisms involved in the biocontrol of plant pathogens. Their direct link with soil microorganisms gives them a key role as biomonitors of the evolution of soil quality or in the monitoring of the application of organic amendments to degraded soils. As a consequence of the importance of soil enzymes on soil processes, there is an increasing interest in their study, as well as in the application of molecular techniques as diagnostic tools.
