Rapid strides have been made in the use of digital image processing tech­ niques for data acquisition in photoelasticity in the last two decades. Techniques such as fringe thinning, fringe clustering, fringe tracing, phase shifting, polarization stepping and Fourier transform methods have significantly contributed to the automation of data acquisition. The recent developments in colour image processing and development of tricolour light source have added a new dimension. The use of time delay and integration (TDI) camera techniques has extended digital photoelasticity for dynamic analysis. Now the field of Digital Photoelasticity has matured to a level where it could be used to solve problems in industries. Apart from developments in data acquisition techniques, several methods have also come into existence for efficient processing of experimental data. Extensive use of computer graphics has found a unique place in presenting the experimental results in a meaningful way. Though there has been significant developments in data processing and data acquisition in the last two decades, there is no book available yet to present these developments in a comprehensive way. The motivation for this book is based on the experience of teaching the course on Experimental Methods in Stress Analysis at lIT Kanpur for the last 10 years. I have always felt a need for introducing Digital Image Processing in an appropriate way, which will be useful for an experimentalist.

This textbook comprises 31 chapters, highlighting advancements in soil-plant systems to enhance nutrient use efficiency. Four primary themes are covered: 1) Introduction and Fundamentals of the Soil-Plant-Atmosphere Continuum and nutrient use efficiency, 2) Soil management for improved nutrient use efficiency, including physical, chemical, biological, and agronomic aspects, 3) Plant physiological, genetic, and molecular biological factors contributing to improved nutrient uptake and use efficiency, and 4) The impact of climate change on soil and plant systems for improving nutrient use efficiency. Additionally, the book includes several chapters that focus on analytical techniques and instrumentation for studying nutrient use efficiency in relation to physico-chemical and biological parameters.

The present book encompasses 31 chapters that focus on the progress made in soil-plant systems to enhance nutrient use efficiency. The book is structured around four major themes: 1) Introduction and Fundamentals of Soil Plant Atmosphere Continuum and nutrient use efficiency, 2) Soil physical, chemical, biological and agronomic management for improving NUE, 3) Plant physiological, genetic & molecular biological basis for improving nutrient uptake & use efficiency, and 4) Climate change aspects related to soil and plant systems for improving NUE. Additionally, the book includes several chapters on analytical techniques and instrumentation for the study of nutrient use efficiency with respect to physico-chemical and biological parameters.
