Available in PDF, EPUB and Kindle. Book excerpt: Crop production depends on the successful implementation of the soil, water, and nutrient management technologies. Food production by the year 2020 needs to be increased by 50 percent more than the present levels to satisfy the needs of around 8 billion people. Much of the increase would have to come from intensification of agricultural production. Importance of wise usage of water, nutrient management, and tillage in the agricultural sector for sustaining agricultural growth and slowing down environmental degradation calls for urgent attention of researchers, planners, and policy makers. Crop models enable researchers to promptly speculate on the long-term consequences of changes in agricultural practices. In addition, cropping systems, under different conditions, are making it possible to identify the adaptations required to respond to changes. This book adopts an interdisciplinary approach and contributes to this new vision. Leading authors analyze topics related to crop production technologies. The efforts have been made to keep the language as simple as possible, keeping in mind the readers of different language origins. The emphasis has been on general descriptions and principles of each topic, technical details, original research work, and modeling aspects. However, the comprehensive journal references in each area should enable the reader to pursue further studies of special interest. The subject has been presented through fifteen chapters to clearly specify different topics for convenience of the readers.

Book excerpt: Hydroponics-A standard methodology for plant biological researches provides useful information on the requirements and techniques needs to be considered in order to grow crops successfully in hydroponics. The main focuses of this book are preparation of hydroponic nutrient solution, use of this technique for studying biological aspects and environmental controls, and production of vegetables and ornamentals hydroponically. The first chapter of this book takes a general description of nutrient solution used for hydroponics followed by an outline of in vitro hydroponic culture system for vegetables. Detailed descriptions on use of hydroponics in the context of scientific research into plants responses and tolerance to abiotic stresses and on the problems associated with the reuse of culture solution and means to overcome it are included. Some chapters provides information on the role of hydroponic technique in studying plant-microbe-environment interaction and in various aspects of plant biological research, and also understanding of root uptake of nutrients and thereof role of hydroponics in environmental clean-up of toxic and polluting agents. The last two chapters outlined the hydroponic production of cactus and fruit tree seedlings. Leading research works from around the world are brought together in this book to produce a valuable source of reference for teachers, researcher, and advanced students of biological science and crop production.

Download or read book Modeling and Control of Greenhouse Crop Growth written by Francisco Rodríguez and published by Springer. This book was released on 2014-11-01 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion of challenges related to the modeling and control of greenhouse crop growth, this book presents state-of-the-art answers to those challenges. The authors model the subsystems involved in successful greenhouse control using different techniques and show how the models obtained can be exploited for simulation or control design; they suggest ideas for the development of physical and/or black-box models for this purpose. Strategies for the control of climate- and irrigation-related variables are brought forward. The uses of PID control and feedforward compensators, both widely used in commercial tools, are summarized. The benefits of advanced control techniques—event-based, robust, and predictive control, for example—are used to improve on the performance of those basic methods. A hierarchical control architecture is developed governed by a high-level multiobjective optimization approach rather than traditional constrained optimization and artificial intelligence techniques. Reference trajectories are found for diurnal and nocturnal temperatures (climate-related setpoints) and electrical conductivity (fertirrigation-related setpoints). The objectives are to maximize profit, fruit quality, and water-use efficiency, these being encouraged by current international rules. Illustrative practical results selected from those obtained in an industrial greenhouse during the last eight years are shown and described. The text of the book is complemented by the use of illustrations, tables and real examples which are helpful in understanding the material. Modeling and Control of Greenhouse Crop Growth will be of interest to industrial engineers, academic researchers and graduates from agricultural, chemical, and process-control backgrounds.

Book excerpt: La colección La horticultura es una ciencia que avanza a pasos agigantados en todos los ámbitos que la componen. El conocimiento que existe sobre esta ciencia y arte es muy amplio y variado. Esto hace que sea muy difícil encontrar compendiada en un solo texto, toda y la suficiente información que puede demandar un lector concreto. Por eso hace falta una definición del tramo de interés particular, este puede variar entre el simple aficionado cuya única pretensión es tener la satisfacción de producir sus propias hortalizas para autoconsumo, hasta el profesional que controla y asesora un cultivo al que se le exige la máxima productividad con los menores insumos posibles de una forma sostenible y no contaminante. Esta colección que se presenta, pretende ser manuales prácticos que permitan el cultivo con un adecuado manejo que conduzca a un rendimiento final aceptable, pero sin renunciar a cierto rigor que necesitaría un científico, técnico o agricultor profesional. Este Manual Este manual está dirigido al productor que utiliza la hidroponía y técnicas de cultivo sin suelo, ya sea a nivel profesional o principiante, cuidando el rigor necesario para el éxito productivo con la máxima eficiencia y sostenibilidad ambiental. Se describen tanto las infraestructuras sencillas o complejas que se puede utilizar y diseñar, como los fundamentos y manejos que garantizan el correcto crecimiento y rendimiento de las plantas cultivadas en estos sistemas. El propietario, responsable o supervisor de una producción agrícola encontrará suficiente información y métodos para evaluar si se aplican los criterios adecuados en su instalación. A su vez quien se inicie en estas técnicas podrá profundizar en esta ciencia y técnica descubriendo las claves y normas para obtener favorables resultados. Los esquemas, figuras y fotografías permitirán entender al lector los fundamentos básicos que completan la descripción de los sistemas y fundamentos que rigen estas técnicas. Miguel Urrestarazu Gavilán es Dr. en Ciencias Biológicas, completa su formación y estudios de ciencias y biología a principio de los años ochenta en la Universidad de Granada, terminando su doctorado en Agricultura Protegida en la Universidad de Almería a principios de los noventa, desde entonces hasta la actualidad ha realizado sus labores de investigación y docencia en sistemas de cultivo sin suelo e hidroponía en la universidad y continuado su labor profesional y docente por prácticamente los cinco continentes.
