Book excerpt: Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A major challenge for agronomists is developing cropping systems that exhibit superior performance across variable environmental conditions. Long-term field research trials provide a direct measure of the effect of environmental conditions within the context of treatment effects. Winter wheat (Triticum aestivum L.) is the most widely grown base crop in dryland systems of the semiarid central Great Plains, but grain yields are limited by nitrogen (N) and soil water availability. The goal of this research was to assess long-term cropping systems of winter wheat-grain sorghum-fallow in dryland. The focus was to determine the effect of three tillage practices and rates of N fertilization rates effects on the efficiency of the management system and grain yields for 2015-2018, and evaluate the yield stability for both crops in a 53-year-old crop rotation and fertility experiment. In the first study we evaluated the long-term effects of three different tillage practices and four N fertilizer rates on grain yield, protein content, and N use efficiency indices of winter wheat and grain sorghum in 2015-2018. The experiment was conducted on a long-term plot initiated in 1965 in Hays, KS as a split-split-plot arrangement of rotation, tillage, and N fertilizer treatments with four replications in a randomized complete block design. The main plots were the crop phase (winter wheat, grain sorghum, or fallow), sub-plots were three tillage treatments [conventional tillage (CT), reduced tillage (RT), and no-tillage (NT)]. The sub-sub-plots were four N rates (0, 22, 45, and 67 kg N ha−1) later modified in the 2015 growing season to 0, 45, 90, and 134 kg ha−1. Results showed tillage × N rate interaction had no significant (P = 0.608) effect on grain yield. Year × tillage and year × N rate had significant (P

This book was released on 2018-11-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing Climate and Resource Use Efficiency in Plants reviews the efficiencies for resource use by crop plants under different climatic conditions. This book focuses on the challenges and potential remediation methods for a variety of resource factors. Chapters deal with the effects of different climatic conditions on agriculture, radiation use efficiency under various climatic conditions, the efficiency of water and its impact on harvest production under restricted soil moisture conditions, nitrogen and phosphorus use efficiency, nitrogen use efficiency in different environmental conditions under the influence of climate change, and various aspects of improving phosphorus use efficiency. The book provides guidance for researchers engaged in plant science studies, particularly Plant/Crop Physiology, Agronomy, Plant Breeding and Molecular Breeding. In addition, it provides valuable insights for policymakers, administrators, plant-based companies and agribusiness companies. Explores climatic effects on agriculture through radiation, water, nitrogen, and phosphorus-use efficiency Guides the planning and research of, and recommendations for, fertilizer application for different crops under various climatic conditions Discusses efficiency improvements for plant and molecular breeders seeking to maximize resource use

Available in PDF, EPUB and Kindle. Book excerpt: The management of croplands has a large impact on the quantity and quality of food and fiber production and on air and water quality, all of which influence the quality of our environment. Management of the nonharvested plant tissues, such as leaves, stems, branches, and roots that constitute the residues from the production of food and fiber, is one of the farm practices that affects crop production via nutrient availability and cycling. Management of these residues also provides opportunities for control of dust in the air and sediments and nutrients in waters through control of soil erosion caused by wind and water. Thus, the task ahead for the management of croplands for improvements in the overall well-being of people involves the application of known effective crop residue management systems to maintain crop production and to reduce wind and water erosion. There is need, as well, for development of more effective management systems through laboratory and field research.
