Download or read book Fertilizer Experiments with Greenhouse Tomatoes Classic Reprint written by John William Lloyd and published by Forgotten Books. This book was released on 2018-04-26 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fertilizer Experiments With Greenhouse Tomatoes In the light of these various experiments it was deemed advisable to run a series of tests in the fertilizing of greenhouse tomatoes grown in ground beds, as both fall and spring crops, particularly to determine the effect of fractional applications of nitrogen and potash at different stages of the plant's development, supplementary to a basic treatment of manure and phosphorus. Records were secured on six fall crops and four spring crops. Upon analyzing the data in reference to the fall cr0p it seemed advisable to conduct a supplementary test involving twelve replications to obtain further data regarding the relative yields of tomato plants treated with manure alone and with manure and superphosphate in the fall crop. Data on the main experiment and on the supplementary test are included in this report. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

Download or read book Policy Implications of Greenhouse Warming written by National Academy of Engineering and published by National Academies Press. This book was released on 1992-02-01 with total page 945 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming continues to gain importance on the international agenda and calls for action are heightening. Yet, there is still controversy over what must be done and what is needed to proceed. Policy Implications of Greenhouse Warming describes the information necessary to make decisions about global warming resulting from atmospheric releases of radiatively active trace gases. The conclusions and recommendations include some unexpected results. The distinguished authoring committee provides specific advice for U.S. policy and addresses the need for an international response to potential greenhouse warming. It offers a realistic view of gaps in the scientific understanding of greenhouse warming and how much effort and expense might be required to produce definitive answers. The book presents methods for assessing options to reduce emissions of greenhouse gases into the atmosphere, offset emissions, and assist humans and unmanaged systems of plants and animals to adjust to the consequences of global warming.
