Put Theory into Practice Scarcity of natural resources, higher costs, higher demand, and concerns about environmental pollution- under these circumstances, improving food supply worldwide with adequate quantity and quality is fundamental. Based on the author's more than forty years of experience, The Use of Nutrients in Crop Plants

An expanded, new and improved American Environmental History textbook for everyone! After years of teaching Environmental History at a major East Coast University without a textbook, Dr. Dan Allosso decided to take matters into his own hands. The result, American Environmental History, is a concise, comprehensive survey covering the material from Dan's undergraduate course. What do people say about the class and the text? "This was my first semester and this course has created an incredible first impression. If all of the courses are this good, I am going to really enjoy my time here. The course has completely changed the way I look at the world." (Student in 2014 class) "One of the few classes I'm really sad is ending, the subject matter is fascinating and Dan is a great guide to it. His approach should be required of all students as it teaches an appreciation for a newer and better way of living." (Student in 2014 class) "Allosso's lectures are fantastic. The best I have ever had. So impressed. The material is always extremely interesting and well-presented." (Student in 2015 class) "It is just a perfect course that I think should be mandatory if we want to save our planet and live responsibly." (Student in 2015 class) "A rare gem for an IB ESS teacher or any social studies teacher looking for an 11th or 12th grade supplementary text that aims to provide an historical context for the environmental reality in America today. Highly recommended." (District Curriculum Coordinator, 2016) "I was so impressed with this material that I am using it as a supplement for a course I teach at my college." (History and Environmental Studies Professor, 2017) Beginning in prehistory and concluding in the present, American Environmental History explores the ways the environment has affected the choices that became our history, and how our choices have affected the environment. The dynamic relationship between people and the world around them is missing from mainstream history. Putting the environment back into history helps us make sense of the past and the present, which will help guide us toward a better future.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Nitrogen is the most important nutrient in agricultural practice because the availability of nitrogen from the soil is generally not enough to support crop yields. To maintain soil fertility, the application of organic matters and crop rotation have been practiced. Farmers can use convenient chemical nitrogen fertilizers to obtain high crop yields. However, the inappropriate use of nitrogen fertilizers causes environmental problems such as nitrate leaching, contamination in groundwater, and the emission of N2O gas. This book is divided into the following four sections: “Ecology and Environmental Aspects of Nitrogen in Agriculture”, “Nitrogen Fertilizers and Nitrogen Management in Agriculture”, “N Utilization and Metabolism in Crops”, “Plant-Microbe Interactions”.

Controlled Release Fertilizers for Sustainable Agriculture provides a comprehensive examination of precision fertilizer applications using the 4-R approach—the right amount of fertilizer at the right time to the right plant at the correct stage of plant growth. This volume consolidates detailed information on each aspect of controlled release fertilizers, including up-to-date literature citations, the current market for controlled release fertilizers and patents. Presenting the tremendous advances in experimental and theoretical studies on sustainable agriculture and related areas, this book provides in-depth insight into state-of-the-art controlled release mechanisms of fertilizers, techniques, and their use in sustainable agriculture. Conventional release mechanisms have historically meant waste of fertilizers and the adverse effects of that waste on the environment. Controlled release delivery makes significant strides in enhancing fertilizer benefit to the target plant, while protecting the surrounding environment and increasing sustainability. - Presents cutting-edge interdisciplinary insights specifically focused on the controlled release of fertilizers - Explores the benefits and challenges of 4-R fertilizer use - Includes expertise from leading researchers in the fields of agriculture, polymer science, and nanotechnology working in industry, academics, government, and private research institutions across the globe - Presents the tremendous advances in experimental and theoretical studies on sustainable agriculture and related areas
