Soil Fertility Management in Agroecosystems
Author: Amitava ChatterjeePublisher: John Wiley & Sons
ISBN: 0891183531
Category : Technology & Engineering
Languages : en
Pages : 160
Book Description
In Soil Fertility Management in Agroecosystems, Editors Amitava Chatterjee and David Clay provide a thoughtful survey of important concepts in soil fertility management. For the requirements of our future workforce, it is imperative that we evolve our understanding of soil fertility. Agronomists and soil scientists are increasingly challenged by extreme climatic conditions. Farmers are experimenting with integrating cover crops into rotations and reducing the use of chemical fertilizers. In other words, there is no such a thing as a simple fertilizer recommendation in today's agriculture. Topics covered include crop-specific nutrient management, program assessment, crop models for decision making, optimization of fertilizer use, cover crops, reducing nitrous oxide emissions, natural abundance techniques, tile-drained conditions, and soil biological fertility.
Contrasting Soil Management Practice, Nitrogen Source, and Harvest Method Effects on Corn Production in Ohio and Tennessee

Book Description
Current global agricultural production is completed with little regards to sustainable soil use. It is clear that the research and use of sustainable management practices must be expanded in order to preserve this natural resource. The objectives of this research were to focus on improving soil fertility and resource use efficiency by 1) evaluating farm management practices to find those that conserve soil and improve yields, 2) looking at alternative methods of fertilizing through the reuse of waste materials in agriculture. The last objective was to 3) test a more efficient method data collection and research production, resulting in more rapid outreach and use of sustainable methods. A study initiated in May 2015 in Ohio compared no-till (NT) and tillage (T) management practices by examining the release of preserved nitrogen (N) from a soil that has been under long-term no-till corn and soybean production. Crop N sufficiency and yields from the T and NT treatments were compared at varying urea application rates. The results showed that the T whole plot consistently provided higher N uptake, crop productivity, and yields when compared to the NT whole plot, but results may have been influenced by unusually high rainfall following fertilizer application. A study initiated in May 2015 in Tennessee tested the use of an industrial byproduct, spent microbial biomass (SMB) as a potential N source for corn. The biomass was compared at varying rates to the current farmer urea application rate. Nitrogen availability and crop uptake was compared within the treatments and no significant differences between the urea treatment and SMB treatment yields were found, indicating that SMB could offer a sufficient source of N in local corn production. To improve efficiency in corn research and data collection, a reduced effort hand-harvest method was compared to the currently accepted method in the Ohio and Tennessee studies. Yields extrapolated using the ten plant harvest method and the current hand harvest method were not found to be significantly different in either study (p>0.05). These results indicate the potential use of this method in future maize studies to improve project efficiency and increase research production.

Book Description
Soil Fertility Improvement and Integrated Nutrient Management: A Global Perspective presents 15 invited chapters written by leading soil fertility experts. The book is organized around three themes. The first theme is Soil Mapping and Soil Fertility Testing, describing spatial heterogeneity in soil nutrients within natural and managed ecosystems, as well as up-to-date soil testing methods and information on how soil fertility indicators respond to agricultural practices. The second theme, Organic and Inorganic Amendments for Soil Fertility Improvement, describes fertilizing materials that provide important amounts of essential nutrients for plants.The third theme, Integrated Nutrient Management Planning: Case Studies From Central Europe, South America, and Africa, highlights the principles of integrated nutrient management. Additionally, it gives case studies explaining how this approach has been implemented successfully across large geographic regions, and at local scales, to improve the productivity of staple crops and forages.
