This book was released on 2022-02-18 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eating locally and developing an urban-rural food continuum is a rapidly evolving movement. Integration of multi-functional forms of agriculture — termed New Forms of Urban Agriculture (NFUA) — could be a critical adaptation to strengthen this movement and for the sustainability of cities. While NFUA have the potential to provide diverse benefits to humans, there is an absence of reliable empirical data on the scale and impact of urban resources on NFUA which has a profound impact on its viability and sustainability. In this book, we shift the focus from how NFUA have potential to impact the urban system to investigate the potential impacts of urban resources on NFUA. Access to resources such as land, labour, clean water, etc. are major barriers to enter the agriculture sector in the cities; the chapters in this book present projects or reviews recent research on the subject from different cities in the world. This edited volume offers critical perspectives from diverse disciplines, expertise, and geographic contexts related to the actual and potential role of urban and peri-urban agriculture in the developing and the developed world where forms, adaptations, and debates around NFUA vary distinctively. Using and urban ecology lens, the book provides empirical evidence of how urban resources of land, water/waste, labour, and biodiversity impact NFUA.

Download or read book Hydroponics written by J. Benton Jones, Jr. and published by CRC Press. This book was released on 1997-06-09 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over 45,000 acres of greenhouse vegetation currently being grown hydroponically throughout the world, hydroponics has become one of the most rapidly expanding new areas of plant research. Although growing plants without soil has been practiced since ancient times, hydroponics-the growing of plants specifically in water or nutrient solutions-has shown itself to be the most cost-effective way of maximizing yield, eliminating plant disease, minimizing labor costs and getting the most out of limited land resources. It's both an economically and ecologically sound approach to field-crop production and soil management. Successfully practicing hydroponics, however, requires a working knowledge of the mechanics of plant growth and a firm grasp of the hydroponics process. Hydroponics: A Practical Guide for the Soilless Grower clearly explains the basics of plant growth and development, the different methods of preparing and using hydroponic nutrient solutions, and hydroponic options for various environmental conditions. It gives the reader instructions for simple experiments and a number of helpful charts, tables and illustrations. Completely up-to-date, the book also describes, in detail, all the latest techniques for hydroponic growing. It addresses new challenges in the field such as growing food for astronauts, practicing hydroponics in inhospitable environments and updating nutrient element supplies for the demands of the next century. It's an ideal guide for anyone interested in plants and how they grow-from casual hobbyists and students to commercial growers and professional plant researchers.

Download or read book Soilless Culture Management written by Meier Schwarz and published by Springer. This book was released on 1995 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydroponics, the method of growing plants without soil, presents a feasible alternative to conventional farming in areas which are short on water supply and limited in agricultural soil. This book will serve as an indispensable guide for students in the agriculture sciences, for agriculture instructors and soilless-culture farmers. It provides up-to-date information on optimal plant nutrition, deficiencies and toxicities of nutrients, plant growth media, optimal root environment, environmental control, carbon dioxide requirements, saline conditions and use of sewage in soilless culture. Other topics include economic aspects of hydroponics, new growth methods and an outlook for the future.

Conclusion Author Bio Publisher Introduction If you start a discussion on hydroponics with a person who is a keen and an avid gardener, he is going to say in a very blase tone, "Oh yeah, you are talking about a gardening method which you are not going to use any soil at all. In fact, you are going to be growing your plants in water." And he is going to be so right. Hydroponics is that gardening method, in which you are going to grow your plants in lots of water. This gardening method is normally implemented in places where the soil is not fertile enough to sustain plant life. I, being a practical doomsayer, predict that within the next 50 years plants are going to be grown extensively through hydroponics because we will have poisoned all the soil, with our chemicals, by then. The idea of hydroponics is not something new. I would not be surprised if in ancient times plants were grown in water, especially in places where one wanted to grow plants indoors - especially in palaces. By the way, a couple of years ago, archaeologists who were doing a little bit of digging in Egypt found some Lotus and water Lily seeds going back more than 2,000 years ago, in some pond excavations in a palace in ancient Egypt. Out of the 20 buried seeds found, which were sent to Kew Gardens London, three of them germinated, and so we have 2,000-year-old lilies, whose ancestors were collected by Egyptian princesses. The princesses in the palace collected the lotuses every day in the ponds and use them for religious rituals as well as adorning their rooms and persons. I do not think they went bathing in the scented waters, because they must have been really careful about the muddy and dirty waters, especially with natural organic fertilizers put in them to promote the growth of the plants."

Download or read book Halophytes and Climate Change written by Mirza Hasanuzzaman and published by CABI. This book was released on 2019-02-14 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains current knowledge and the most recent developments in the field of halophyte biology, ecology, and potential uses. Halophytes are characterised as plants that can survive and complete their life cycle in highly saline environments. This book explores the adaptive mechanisms and special features of halophytes that allow them to grow in environments that are unsuitable for conventional crops and considers their role as a source of food, fuel, fodder, fibre, essential oils, and medicines. Halophytes and Climate Change includes coverage of: - Special morphological, anatomical, and physiological features of halophytes - Ion accumulation patterns and homeostasis in halophytes - Potential use of halophytes in the remediation of saline soil - Growth and physiological response and tolerance to toxicity and drought - Mangrove ecology, physiology, and adaptation Written by a team of international authors and presented in full colour, this book is an essential resource for researchers in the fields of plant physiology, ecology, soil science, environmental science, botany, and agriculture.
