Download or read book Relationships Between Cropping Practices Soil Quality and Maize Zea Mays L Yield in Morogoro Region Tanzania written by Steven Anthony Doyle and published by . This book was released on 2018 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize (Zea mays L.) is the principal food source for Eastern Africa’s rising populations. In Morogoro Region, Tanzania, 56% of agricultural land is cropped with maize and 90% of its people are smallholder farmers. For these reasons, understanding the relationship between crop management decisions, agricultural soil quality, and maize yield is of critical importance. Field management practices were recorded during the November – January (short) rainy season crop, and the March – June (long) rainy season, and water use during the short rainy season. Soil samples were taken from each field in June 2017 and analyzed for soil quality parameters pH, total nitrogen (TN), soil organic carbon (SOC), bulk density (BD), texture, aggregate stability (AS), and penetration resistance. Analyses indicated that during both the short and long rainy seasons, maize production resulted in a lower pH than in vegetable production, or maize – cowpea intercrop. Fields which were cropped with maize in the long rainy season had higher clay content (Clay) than did those cropped with a maize – cowpea intercrop. Sand content (Sand) appeared to be higher in fields cropped with a maize – cowpea intercrop in maize in the long rainy season. Textural variation was accounted for a spatial gradient in soil series, which likely informed crop choice. Aggregate stability was found to be higher in fields cropped with maize in the short rainy season than with vegetable. TN, SOC, BD, silt content (Silt), and penetration resistance were not found to vary between crop management practice. Each soil quality parameter was entered into a linear regression model and a mixed effects model with long rainy season maize yields to determine the property’s association with maize production. These analyses indicated that BD and sand concentration were negatively affecting maize yields while silt concentration, and to a lesser extent, SOC and AS were positively affecting maize yields in the sampled fields. From these findings, farmers would be advised to increase their SOC through manure or cover crop incorporation, while decreasing tillage rates. They may also be advised to cultivate maize on soils with higher Clay and vegetables on soils with higher Sand.

Available in PDF, EPUB and Kindle. Book excerpt: Encyclopedia of Agriculture and Food Systems, Second Edition, Five Volume Set addresses important issues by examining topics of global agriculture and food systems that are key to understanding the challenges we face. Questions it addresses include: Will we be able to produce enough food to meet the increasing dietary needs and wants of the additional two billion people expected to inhabit our planet by 2050? Will we be able to meet the need for so much more food while simultaneously reducing adverse environmental effects of today’s agriculture practices? Will we be able to produce the additional food using less land and water than we use now? These are among the most important challenges that face our planet in the coming decades. The broad themes of food systems and people, agriculture and the environment, the science of agriculture, agricultural products, and agricultural production systems are covered in more than 200 separate chapters of this work. The book provides information that serves as the foundation for discussion of the food and environment challenges of the world. An international group of highly respected authors addresses these issues from a global perspective and provides the background, references, and linkages for further exploration of each of topics of this comprehensive work. Addresses important challenges of sustainability and efficiency from a global perspective. Takes a detailed look at the important issues affecting the agricultural and food industries today.

Download or read book Agroecological Practices For Sustainable Agriculture Principles Applications And Making The Transition written by Alexander Wezel and published by World Scientific. This book was released on 2017-06-19 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Good agroecological practices are indispensable for the development of sustainable agriculture. In this book, principles, diversity and applications of agroecological practices for a range of systems are presented, transforming scientific research and participatory knowledge of production into practical application. It illustrates a broad range of research and teaching being used within the farming community to demonstrate best practice and current state-of-play within the field. Agroecological methods used in crop farming, grass-based livestock farming, fish production, and other complex farming systems are discussed. Conclusions are drawn from studies to provide an outlook on future trends of agroecological practices and on policies supporting implementation.Due to emphasis on real-life application, it is relevant not only to students of the agricultural sciences and public policy, but also to researchers, stakeholders and policy makers involved in the development of sustainable agriculture.

Download or read book Organic Waste Composting through Nexus Thinking written by Hiroshan Hettiarachchi and published by Springer Nature. This book was released on 2020-11-23 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic 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.
