Book Synopsis Understanding Spatial and Temporal Variability of Corn Yield to Improve Nitrogen Use Efficiency by : Olivia Davidson
Download or read book Understanding Spatial and Temporal Variability of Corn Yield to Improve Nitrogen Use Efficiency written by Olivia Davidson and published by . This book was released on 2020 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two field scale studies were performed in five corn fields across southwest Michigan over three years in order to examine i) the influence of delayed corn plant emergence on final yield, and ii) the effect of strategic, varied nitrogen management on final yield, profit, and nitrogen use efficiency. Individual corn plant emergence date was documented, and kernel weight, kernel number, and biomass weights were analyzed in order to examine the importance of uniform plant stands in achieving high yields, analyzed by the known historical yield stability (Basso et al., 2019). The results showed a 22-gram decrease from early to late emergence and a 15-gram decrease in total kernel weight from early to medium emergence date, equivalent to 1,825 and 1,244 kg/ha decrease in yield. Yield stability zones differentiation showed a 19.9-gram decrease in relative total kernel weight (1,651 kg/ha) from historically high and stable yield to low and stable yield. More variability in days after planting and decreased yields were seen in the low and medium yielding zones. For the second field study, a procedure was created to variably rate nitrogen fertilization using remotely sensed imagery and crop modelling using the SALUS crop model. Whole plant destructive samples and yield monitor data were analyzed to examine the spatial and temporal variability in differing yield stability zones among all study sites. The results showed no statistically significant difference in yield or profit between nitrogen fertilization zones in most fields, while increases in nitrogen use efficiency were seen in all tactically reduced fertilization rate zones.

Book Synopsis Agriculture and Phosphorus Management by : Andrew N. Sharpley
Download or read book Agriculture and Phosphorus Management written by Andrew N. Sharpley and published by CRC Press. This book was released on 1999-12-20 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the Chesapeake Bay as a case study, Agriculture and Phosphorus Management discusses the impact and management of phosphorus in watersheds. Although urban and other sources contribute phosphorus to the Bay, the papers presented focus on how its role in agriculture impacts water quality. They review the new guidelines and legislation slated for implementation by 2002 directed towards sustainable nutrient management and strategies for implementing them. Phosphorus, an essential element for plant and animal growth, has long been recognized as necessary to eliminate deficiencies and to maintain profitable crop and livestock production. It can increase the biological productivity of surface waters by accelerating eutrophication. Human activities accelerate the rate of eutrophication - principally by increasing the rate at which phosphorus enters the aquatic system. Written by experts from a range of disciplines Agriculture and Phosphorus Management provides a deeper understanding of the diverse, dynamic, and complex factors controlling the impact of agricultural phosphorus management on production and water quality. Each contributor addresses the questions: what do we know, what do we still need to know, where are the major gaps in our knowledge, and how does the information relate to phosphorus management strategies in the Bay Watershed, and other watersheds? As a result this series of papers provides a unique collection of information of regional, national, and international significance and gives prioritized phosphorus management options for not only the Chesapeake Bay Watershed, but for watersheds around the world.

Download or read book Roots written by Jun J. Abe and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The root is the organ that functions as the interface between the plant and the earth environment. Many human management practices involving crops, forests and natural vegetation also affect plant growth through the soil and roots. Understanding the morphology and function of roots from the cellular level to the level of the whole root system is required for both plant production and environmental protection. This book is at the forefront of plant root science (rhizology), catering to professional plant scientists and graduate students. It covers root development, stress physiology, ecology, and associations with microorganisms. The chapters are selected papers originally presented at the 6th Symposium of the International Society of Root Research, where plant biologists, ecologists, soil microbiologists, crop scientists, forestry scientists, and environmental scientists, among others, gathered to discuss current research results and to establish rhizology as a newly integrated research area.

Download or read book Climate Change and Soil Interactions written by Majeti Narasimha Var Prasad and published by Elsevier. This book was released on 2020-03-06 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate Change and Soil Interactions examines soil system interactions and conservation strategies regarding the effects of climate change. It presents cutting-edge research in soil carbonization, soil biodiversity, and vegetation. As a resource for strategies in maintaining various interactions for eco-sustainability, topical chapters address microbial response and soil health in relation to climate change, as well as soil improvement practices. Understanding soil systems, including their various physical, chemical, and biological interactions, is imperative for regaining the vitality of soil system under changing climatic conditions. This book will address the impact of changing climatic conditions on various beneficial interactions operational in soil systems and recommend suitable strategies for maintaining such interactions. Climate Change and Soil Interactions enables agricultural, ecological, and environmental researchers to obtain up-to-date, state-of-the-art, and authoritative information regarding the impact of changing climatic conditions on various soil interactions and presents information vital to understanding the growing fields of biodiversity, sustainability, and climate change. Addresses several sustainable development goals proposed by the UN as part of the 2030 agenda for sustainable development Presents a wide variety of relevant information in a unique style corroborated with factual cases, colour images, and case studies from across the globe Recommends suitable strategies for maintaining soil system interactions under changing climatic conditions
