Book excerpt: This book which is edited by Dr Bao-Luo Ma, a senior research scientist from Agriculture and Agri-Food in Canada, includes contributions from more than twenty-eight scientists in this dynamic field from around the world. This book synthesises the latest innovations and integrated knowledge from science disciplines as diverse as agronomy, soil science, ecology, economy, and social sciences. The global population is projected to reach nine billion by mid-century. Questions continue to arise concerning the ability of the agriculture sector to keep pace with the demands for food, feed, fibre and fuel of an increasing population in the near future, as well as finding a way of sustaining both the production system and the environment. Crop rotations, an ancient practice that has gained renewed interest in recent years, involve growing different crop species/varieties on the same piece of land in consecutive growing seasons (years). The direct and indirect benefits of this practice to the production system and the environment have been recognised for millennia. In recent years, it has been documented that crop rotations coupled with conservation tillage has enhanced the physical, chemical and biological properties of soil, improved seasonal nitrogen availability, and provided nitrogen inputs through symbiotic nitrogen fixation by legumes. This strategy can also lead to a better balance of plant nutritional requirements and a shift in soil mycorrhizal populations, interrupt insect populations, increase root activity, reduce disease severity, enhance environmentally-friendly biodiversity, and lower per-area greenhouse gas emissions or per-yield based carbon footprints. This book serves as one of the most recent and valuable reference on these multi-disciplines, and targets audiences at the undergraduate and graduate level, including crop, soil and agronomy scientists as well as environment scientists and policy-makers.

Download or read book Struggling with the Environment written by Erik Thoen and published by Brepols Publishers. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is always a struggle with the environment since agricultural production is in fact applied ecology. However, in the past the struggle with the environment was to a large extent determined by the social organisation which was regionally very diverse. The aim of this volume is to find out how, when and within which structural boundaries, land was made useful for agriculture. In the first part of each chapter, this is studied in general, focusing on the evolution of land use: how and why was land reclaimed and by whom? How intensively was this land used? Which actors played a part in this process? What were the environmental and social limits? In the second part the production techniques and production systems are scrutinized: crop choices, crop rotations, the importance of fallow and cattle, crop yields etc. All this is looked at in light of different farming strategies and social conditions. The comparative approach of this volume also enables a new and innovating perspective on the occurrence and impact of 'agricultural' and 'green' revolutions in the past.
Download or read book Crop Rotation written by Samiha Ouda and published by Springer. This book was released on 2018-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tackles the issue of using crop rotation to increase food production and secure it for the growing population of the future. Crop rotation can be a solution of food gaps in the developing counties. Crop rotation plays an important role in attaining soil sustainability and in controlling pests and weeds. It can alleviate damage caused by climate change by reducing losses in productivity of the crops, minimizing soil fertility loss and increase irrigation water productivity. This book also includes the reviews of a large number of crop rotations that have been published internationally, and additionally, the crop rotations that have been implemented in Egypt have a unique characteristic to them and therefore, a large number of those reviews have also been included.

This book was released on 2018-09-10 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gerhard Brankatschk provides solutions for methodological limitations of agricultural Life Cycle Assessments (LCAs). The author solves challenges of attributing multifunctionality (co-products) and temporal system boundaries (crop rotations) of agricultural systems by establishing two new Life Cycle Inventory methodologies, which conform to ISO-standards on LCA. The new methods help to assess temporal, spatial, and multifunctional complexity of agricultural systems and to improve the reliability of life cycle based sustainability assessments of agriculture.

Download or read book Estimating Crop Rotations as Dynamic Cycles Using Geo referenced Field Data written by Duncan MacEwan and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop rotation systems are an important part of agricultural production for managing pests, diseases, and soil fertility. Rotation system decisions are based on a tradeoff between the immediate profits from a crop planted this season with the future costs (or benefits) manifest through changes in yield and production costs for future crops. Field-specific capital such as soil characteristics, micro-climate, water quality, and farmer management skills alter the inter-temporal rotation effects between crops. In other words, agricultural production decisions are dynamic processes which will vary across regions with heterogeneous field-capital. Due to a dearth of field-level data, agricultural production is rarely modeled as the solution to a dynamic economic problem. Similarly, much of the existing literature focuses on aggregate regional models which omit spatial variation in production conditions across regions. The dynamics and spatial variation of rotation system decisions have potentially important implications for spatially-dependent agricultural-environmental policies, sustainable agriculture, and accurate representation of the spatial and dynamic components of supply response. Historically, decisions at the field-level of detail have been difficult to observe consistently across time in anything other than experimental plots. In this dissertation I use a unique geo-referenced panel dataset of field-level production covering over 14,000 fields (over 1 million acres) and 13 years. I use these data to estimate empirically observed crop rotation systems using methods from the Bioinformatics literature. I estimate reduced form models of land use and rotation system choice at the field-level in order to determine what factors influence production decisions. Based on the insights of the reduced form analysis, I develop a theoretical model of the two-crop rotation problem and prove that the optimal solution is an infinite cycle of discrete switches between crops. I generalize the two crop theoretical model to a dynamic programming model with multiple crops and estimate the structural parameters which satisfy the Euler conditions for a one-year carry-over effect between crops. I solve the dynamic programming model and simulate supply response to spatial heterogeneity in field-specific physical capital and exogenous price shocks.

This book focuses on the FAM- project (FAM Munich Research Network on Agroecosystems) of the 1990s as a means to assessing, forecasting, and evaluating changes in the agroecosystems that are necessary for agricultural sustainability. The management of two separate management systems: an organic and an integrated farming system are described to provide an interdisciplinary approach Changes of matter fluxes in soils, changes of trace gas fluxes from soils, precision farming in a small scale heterogen landscape, influence of management changes on flora and fauna, as well as the development of agroecosystem models, the assessment of soil variability and the changes in nutrient status are important aspects of this book.* Contains detailed results and insight of a long-time project on agricultural sustainability* Provides an interdisciplinary approach for comprehensive understanding by scientists and researchers of soil, plants, agriculture, and environment * Includes an international perspective
