Available in PDF, EPUB and Kindle. Book excerpt: The literature which has been reviewed presented overwhelming evidence for the need to consider weather in agricultural experiments. The primary purpose of this study has been to find a single atmospheric-soil moisture stress variable which is correlated with final corn yield. It is hoped that the use of this moisture stress variable will facilitate and encourage the consideration of weather with other environmental and technological factors in agricultural research and extension. The consideration of the weather will help evaluate the spatial and temperal representativeness of experimental results. Two atmospheric-moisture stress variables were found to be highly correlated with unreplicated plot corn yields from secon year corn in the 4-year rotation experiment, corn-corn-oats-meadow, at the Iowa State University Agronomy Farm, Ames, Iowa. One of the variable was the number of days on which the corn was estimated to be under no moisture stress, in the period 6 weeks before 3 weeks after date of silking. The estimation of moisture stress or no moisture stress conditions was based on the experimental relation found by Denmead and Shaw (10). OTL = f(ETFC), where OTL is the percent available soil moisture below which the corn plant loses turgor. The amount of available soil moisture at the turgor loss point depends upon the atmospheric demands or the evapotranspirations at field capacity, ETFC. The ETFC was estimated from the daily evaporation form a weather Bureau class a evaporation pan. (...).

Available in PDF, EPUB and Kindle. Book excerpt: Soil Management and Climate Change: Effects on Organic Carbon, Nitrogen Dynamics, and Greenhouse Gas Emissions provides a state of the art overview of recent findings and future research challenges regarding physical, chemical and biological processes controlling soil carbon, nitrogen dynamic and greenhouse gas emissions from soils. This book is for students and academics in soil science and environmental science, land managers, public administrators and legislators, and will increase understanding of organic matter preservation in soil and mitigation of greenhouse gas emissions. Given the central role soil plays on the global carbon (C) and nitrogen (N) cycles and its impact on greenhouse gas emissions, there is an urgent need to increase our common understanding about sources, mechanisms and processes that regulate organic matter mineralization and stabilization, and to identify those management practices and processes which mitigate greenhouse gas emissions, helping increase organic matter stabilization with suitable supplies of available N. - Provides the latest findings about soil organic matter stabilization and greenhouse gas emissions - Covers the effect of practices and management on soil organic matter stabilization - Includes information for readers to select the most suitable management practices to increase soil organic matter stabilization

Download or read book Weed Crop Competition written by Robert L. Zimdahl and published by John Wiley & Sons. This book was released on 2007-11-19 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past 20 years, the first edition of this text has been widely cited as authoritative academic reference. The latest edition continues the tradition set by the original book, and covers weed science research that has been published since 1980. This book aims to reduce the instance of research duplication—saving scientists and supporting institutions time and money. Not only does the second edition of Weed Crop Competition review, summarize, and combine current research; it critiques the research as well. This text has the potential to accelerate advancements in weed crop competition, which remains an important factor that affects crop yields. Scientists in foreign countries where access to literature is often limited or nonexistent, will find the information in this text invaluable. Weed scientists, crop scientists, plant ecologists, sustainable agriculturists, and organic agriculturists will be well-pleased with this long overdue and much needed new editionWeed Crop Competition provides a unique reference that reviews, summarises and synthesizes the literature published concerning research on this topic. The first edition has been one of the most frequently cited sources in weed science for the past 20 years. The second edition covers the significant body of literature that has been published since 1980. Originally intended to survey existing research, the intent of the book is to reduce the instance of research duplication, thus saving scientists and their institutions time and money, and expediting advancements in weed crop competition, an important factor affecting crop yields. Scientists in foreign countries where access to the literature is often limited or non-existent, find the information an invaluable resource. This long overdue and much needed new edition rejuvenates the tradition set by the original book.
