Hydroponics And Protected Cultivation

A comprehensive, practical text which covers a diverse range of hydroponic and protected cropping techniques, systems, greenhouse types and environments. It also details the use of indoor plant factories, vertical systems, organic hydroponics and aquaponics. Worldwide hydroponic cropping operations can vary from large, corporate producers running many hectares of greenhouse systems particularly for crops such as tomato, cucumber, capsicum and lettuce, to smaller-scale growers growing fresh produce for local markets.

A greenhouse provides an essential means of livelihood to its owner and must be economically practical for the particular climate in which it stands. Greenhouses: Advanced Technology for Protected Horticulture addresses the major environmental factors of light, temperature, water, nutrition, and carbon dioxide, and features extensive discussions of greenhouse types, construction, and climate control. The book highlights technology such as hydroponics, computer control of environments, and advanced mathematical procedures for environmental optimization. Greenhouses: Advanced Technology for Protected Horticulture is the definitive text/reference for the science of greenhouse engineering and management. The author Dr. Joe J. Hanan, Professor Emeritus of Colorado State University, is the recipient of the Society of American Florists' (SAF) 2000 (Millenium) Alex Laurie Award for Research and Education. The Alex Laurie Award is presented annually to an individual who has made broad-scope, long-lasting contributions to the floriculture industry through research or education. The award is named for Alex Laurie, a professor at The Ohio State University, who pioneered work in many areas of floriculture. "Joe is one of the most precise floricultural researchers I have known," said Dr. Gus De Hertogh, Chairman of SAF's Research Committee. "That excellence is reflected in his latest book, Greenhouses, Advanced Technology for Protected Horticulture, which was published in 1998, nine years after his official 'retirement.'"

This book provides discussion on the importance of hydroponics with particular focus on the nutrient film technique for the production of premium, fresh vegetables in a highly economically feasible method. It highlights this culture of growing as one of the most efficient agricultural practices for a sustainable market and also addresses the numerous challenges faced in the production of crops grown in soil. Nutrient Film Technique Hydroponics describes detailed instructions on the set up of an efficient system, including applications for lower budgets, new business ventures, and gives a detailed outline for the construction of an ideal hydroponic system. It also reveals the secrets to turning a hydroponic system into a profitable business by providing the necessary templates for tracking a successful endeavor. This book also contains references for further reading and a comprehensive index.

The frontiers of technologies have been constantly expanded in many industries around the world, including the agricultural sector. Among many “frontier technologies” in agriculture, are protected agriculture, precision agriculture, and vertical farming, all of which depart substantially from many conventional agricultural production methods. It is not yet clear how these technologies can become adoptable in developing countries, including, for example, South Asian countries like India. This paper briefly reviews the issues associated withthese three types of frontier technologies. We do so by systematically checkingthe academic articleslisted in Google Scholar, which primarily focus on these technologies in developing countries in Asia. Where appropriate, a few widely-cited overview articles for each technology were also reviewed. The findings generally reveal where performances of these technologiescan be raised potentially, based on the general trends in the literature. Where evidence is rich, some generalizable economic insights about these technologies are provided. For protected agriculture, recent research has focusedsignificantly on various features of protective structures (tunnel heights, covering materials, shading structures, frames and sizes) indicating that there are potentials for adaptive research on such structures to raise the productivity of protected agriculture. The research on protected agriculture also focuses on types of climate parameters controlled, andenergy structures, among others. For precision agriculture, recent research has focused on the spatial variability of production environments, development of efficient and suitable data management systems, efficiency of various types of image analyses and optical sensing, efficiency of sensors and related technologies, designs of precision agriculture equipment, optimal inputs and service uses, and their spatial allocations, potentials of unmanned aerial vehicles (UAVs) and nano-technologies. For vertical farming, research has often highlighted the variations in technologies based on out-door / indoor systems, ways to improve plants’ access to light (natural or artificial), growing medium and nutrient / water supply, advanced features like electricity generation and integration of production space into an office / residential space, and water treatment. For India, issues listed above may be some of the key areas that the country can draw on from other more advanced countries in Asia, or can focus in its adaptive research to improve the relevance and applicability of these technologies to the country.

The book carries 17 s dealing with space saving, maximizing the efficiency of fertigation, mulching, integrated pest, disease and nutrient management (IPDNM) and engineering aspects of structures.Net houses, poly houses, rain shelters, poly tunnels, uses of plastics in horticulture and cold chains for storage and marketing are elaborated. Hydroponics and aeroponics are discussed.
