Download or read book Soil Physical Environment and Plant Growth written by Pradeep K Sharma and published by Springer Nature. This book was released on 2023-08-28 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook on the applied aspects of soil physics covers introduction to soil physical properties and processes, and their evaluation and management in relation to plant growth. It distinguishes physical properties that directly influence plant growth from those that indirectly affect agricultural productivity. Chapters are also devoted to the concept of soil health and the role of soil physics on preservation of soil health and environmental quality. As such, this book fills a unique knowledge gap for agriculture and agronomy students, course directors as well as field professionals.
Download or read book Understanding Options for Agricultural Production written by G.Y. Tsuji and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993.

Download or read book Evaluation and Sensitivity of a Soil water atmosphere plant Simulation Model written by Yoshitaka Araki and published by . This book was released on 1984 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluation and sensitivity analysis of a soil-water--- atmosphere-plant simulation model, SWATRE, developed by Feddes et al (1978) in The Netherlands was conducted. The evaluation was performed with the observed data obtained by Cuenca (1978) for three different irrigation levels in UC82 variety tomato fields in Davis, California. SWATHE requires about one hundred different input data from the soil-water-atmosphere-plant (SWAP) system. Since the specific required data were not available in every case, unique approaches were applied to define a root sink function, soil characteristic curve, rooting depth, soil hydraulic conductivity, and saturated soil moisture content. The basic water balance equation of SWATRE is a function of the differential soil Ti tie: Evaluation and Sensitivity of a Soil-Water-Atmosphere-P1ant Simulation Model moisture capacity, hydraulic conductivity, and root sink function (Feddes et al., 1978). Additionally potential evapotranspiration affects the simulation of the SWAP system significantly. The importance of these variables was investigated by applying sensitivity analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Digital Terrain Analysis in Soil Science and Geology, Second Edition, synthesizes the knowledge on methods and applications of digital terrain analysis and geomorphometry in the context of multi-scale problems in soil science and geology. Divided into three parts, the book first examines main concepts, principles, and methods of digital terrain modeling. It then looks at methods for analysis, modeling, and mapping of spatial distribution of soil properties using digital terrain analysis, before finally considering techniques for recognition, analysis, and interpretation of topographically manifested geological features. Digital Terrain Analysis in Soil Science and Geology, Second Edition, is an updated and revised edition, providing both a theoretical and methodological basis for understanding and applying geographical modeling techniques. Presents an integrated and unified view of digital terrain analysis in both soil science and geology Features research on new advances in the field, including DEM analytical approximation, analytical calculation of local morphometric variables, morphometric globes, and two-dimensional generalized spectral analytical methods Includes a rigorous description of the mathematical principles of digital terrain analysis Provides both a theoretical and methodological basis for understanding and applying geographical modeling
Download or read book Soil Plant Water Analysis A Complete Knowledge written by Avijit Ghosh and published by Sankalp Publication. This book was released on 2019-08-10 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for this soil, plant and water analysis manual grew out of the Soil Test Calibration Program within the region’s national agricultural programs that laid the basis for sound fertilizer recommendations. If soil and plant tests are not reliable, the process of sampling and analysis is meaningless and undermines the validity of any agronomic trials. As no essential element can substitute for another, it is critically important to identify where and when such deficiencies occur. That’s where the role of soil and plant analysis comes in. Techniques have been developed to evaluate soil fertility constraints based on soil chemical extraction and analysis of the plants that grow on such soils. Both are complementary and, when calibrated with field crop responses to fertilizer, provide a rational basis to identify what elements are missing, and how much fertilizer, whether organic or inorganic, to apply. Therefore, soil and plant analysis laboratories have a vital role in agricultural development.

Download or read book Development and Evaluation of a Cost Effective Plant Growth Media Moisture Densor and Development of an Aqueous Data Transmission System for Irrigation Purposes written by Steven Michael Pickett and published by . This book was released on 2015 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to accurately monitor and transit the moisture content of soilless growing media in the rooting zone is critical for plant-based research, production of high value crops, and other agricultural production. The focus of this study is the development and evaluation of a cost effective moisture sensor designed to measure the plant-available moisture content of growing media and the development of a aqueous data transmission method for relaying this information back to a central location. While there are currently many commercially available soil moisture sensors on the market, the aim of this research is not to develop a more accurate sensor but to design a comparably capable sensor that is more cost effective for the end user to achieve a higher spatial resolution of their moisture measurement by incorporating more sensors over a given area. Traditional wired and wireless communication methods currently used in industry would require additional infrastructure to transmit this moisture data back to central local that adds to the cost of the system. The proposed aqueous data transmission system was designed to relay moisture sensor output utilizing the existing irrigation infrastructure for communication. This system, if commercialized, could improve currently employed automated irrigation for production systems by optimizing water management based on zone requirements, thereby increasing production efficiency while minimizing the potential for off-site movement of contaminates. Likewise, this low cost approach will allow a network of soil moisture sensors to address the spatial variation of moisture content within an area; thus permitting site-specific irrigation within a production area (field, greenhouse etc).
