Available in PDF, EPUB and Kindle. Book excerpt: Sustainable management of soils is an important global issue of the 21st century. Feeding roughly 8 billion people with an environmentally sustainable production system is a major challenge, especially considering the fact that 10% of the world’s population at risk of hunger and 25% at risk of malnutrition. Accordingly, the 68th United Nations (UN) general assembly declared 2016 the “International Year of Pulses” to raise awareness and to celebrate the role of pulses in human nutrition and welfare. Likewise, the assembly declared the year 2015 as the “International Year of Soils” to promote awareness of the role of “healthy soils for a healthy life” and the International Union of Soil Science (IUSS) has declared 2015-2024 as the International Decade of Soils. Including legumes in cropping systems is an important toward advancing soil sustainability, food and nutritional security without compromising soil quality or its production potential. Several textbooks and edited volumes are currently available on general soil fertility or on legumes but‚ to date‚ none have been dedicated to the study of “Legumes for Soil Health and Sustainable Management”. This is important aspect, as the soil, the epidermis of the Earth (geoderma)‚ is the major component of the terrestrial biosphere. This book explores the impacts of legumes on soil health and sustainability, structure and functioning of agro-ecosystems, agronomic productivity and food security, BNF, microbial transformation of soil N and P, plant-growth-promoting rhizobacteria, biofertilizers, etc. With the advent of fertilizers, legumes have been sidelined since World War II, which has produced serious consequences for soils and the environment alike. Therefore, legume-based rational cropping/soil management practices must support environmentally and economically sustainable agroecosystems based on (sequential) rotation and intercropping considerations to restore soil health and sustainability. All chapters are amply illustrated with appropriately placed data, tables, figures, and photographs, and supported with extensive and cutting-edge references. The editors have provided a roadmap for the sustainable development of legumes for food and nutritional security and soil sustainability in agricultural systems, offering a unique resource for teachers, researchers, and policymakers, as well as undergraduate and graduate students of soil science, agronomy, ecology, and the environmental sciences.

Download or read book Legume Nitrogen Fixation in Soils with Low Phosphorus Availability written by Saad Sulieman and published by Springer. This book was released on 2017-06-10 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thoughtful and provocative book provides a concise, up-to-date presentation of how current and projected future phosphorus scarcity will affect legume growth and their symbiotic nitrogen-fixing capabilities. It is a timely examination of the physiological and molecular responses of nodules to phosphorous deficiency in attempt to identify common principles. Students and researchers in the many disciplines related to crop productivity will find this title an exciting contribution in the area of plant stress physiology. The knowledge in this volume can also aid plant breeders, particularly through new methods of genetic engineering, in developing unique and adaptive cultivars with higher symbiotic efficiency. The awareness of the rapidly rising world population must translate into a parallel increase in agricultural production in order to sustain the growing population both now and in the future. Hence, the demand for food crops to produce proteins and vegetable oil for human consumption is going to increase considerably during the coming years. The essential role of legumes in agriculture is well-recognized, given the abundant levels of proteins and oils found in plants along with their enormous contribution to the sustainability of agricultural systems and human health. The capacity of legumes to fix nitrogen (N2) in partnership with rhizobia provides an input-saving and resource-conserving alternative, thereby reducing the need for chemical fertilizers while enhancing overall crop productivity. The use of N2-fixing legumes to produce plant proteins results in a substantial decrease in the consumption of fossil fuels and therefore also in the agricultural effects to global warming. However, a major constraint to legume production is low soil phosphorus (P) availability, considering that an overwhelming majority of the world’s soils are classified as P-deficient. Low-P availability is especially problematic for legumes, since legume nodules responsible for N2 fixation have a high P requirement. Therefore, this book explains how nodule N2 fixation responds to low P availability, which is crucial for improving legume production and maintaining agricultural sustainability in the context of the global P crisis.

Available in PDF, EPUB and Kindle. Book excerpt: Global climate change has created unprecedented challenges for human civilization due to its widespread adverse consequences, including a reduction in crop yield and threatening food security across the globe. Among the crop plants, legumes have great potential for ameliorating global warming since they can reduce carbon emissions by lowering reliance on the application of chemical fertilizers, by increasing nitrification and carbon sequestration in soil, and by providing protein-rich diets to both humans and livestock. This book identifies the extent of climate-induced stresses on legume plants and focuses on achieving food security through sustainable agricultural practices. This book compiles recent research findings and reviews on climate-related problems, the potential of legumes in ameliorating the impacts of climate change, as well as better management of agricultural land and practices for achieving environmental sustainability and food security. This book will serve as guidelines for scientists, agricultural practitioners, and policymakers working to achieve food security and better management of climate-induced stresses in agricultural interventions. It will also be useful as a reference book for researchers and students of both graduate and postgraduate levels.

Download or read book Legume Nitrogen Fixation in a Changing Environment written by Saad Sulieman and published by Springer. This book was released on 2015-04-24 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population will grow more rapidly during the few coming years. This must be accompanied by a parallel increase in the agricultural production to secure adequate food. Sustainability considerations mandate that alternatives to chemical nitrogen fertilizers must be urgently sought. Biological nitrogen (N2) fixation, a microbiological process which converts atmospheric N2 into a plant-usable form, offers this alternative. Among these renewable sources, N2-fixing legumes offer an economically attractive and ecologically sound means of reducing external inputs and improving internal resources. Environmental factors such as drought, elevated temperature, salinity, soil acidity and rising CO2 are known to dramatically affect the symbiotic process and thus play a part in determining the actual amount of nitrogen fixed by a given legume in the field. Understanding how nodule N2 fixation responds to the environment is crucial for improving legume production and maintaining sustainability in the context of global change. In this thoughtful and provocative new Brief, we provide critical information on how current and projected future changes in the environment will affect legume growth and their symbiotic N2 fixing capabilities. Each section reviews the main drivers of environmental change on the legume performance that include drought, elevated temperature, salinity and rising CO2, and soil acidity. Importantly we discuss the molecular approaches to the analysis of the stress response in legumes and the possible biotechnological strategies to overcome their detrimental effects.

Download or read book Plant Genetic Resources of Legumes in the Mediterranean written by Nigel Maxted and published by Springer Science & Business Media. This book was released on 2001-05-31 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic erosion, that is, the loss of native plant and genetic diversity has been exponential from the Mediterranean Basin through the Twentieth century. This careless eradication of species and genetic diversity as a result of human activities from a 'hot-spot' of diversity threatens sustainable agriculture and food security for the temperate regions of the world. Since the early 1900s there has been a largely ad hoc movement to halt the loss of plant diversity and enhance its utilisation. The Convention on Biological Diversity and Food and Agriculture Organisation of the United Nations International Undertaking on Plant Genetic Resources, both highlight the need to improve conservation methodologies and enhance utilisation techniques. It has been argued that the most important component of biodiversity is the genetic diversity of crop and forage species used to feed humans and livestock. These cultivated and related wild species provides the raw material for further selection and improvement. Leguminosae species are of major economic importance (peas, chickpeas, lentils and faba beans, as well as numerous forage species) and provide a particularly rich source of protein for human and animal foods. Their distribution is concentrated in the Mediterranean region and therefore the improvement of their conservation and use in the region is critical. This text is designed to help ensure an adequate breadth of legume diversity is conserved and to help maximise the use of that conserved diversity. The subjects of conservation and use of legume diversity, the Mediterranean ecosystem and taxonomy of legumes are introduced. Generic reviews of the taxonomy, centre of diversity, ecogeographic distribution, genetic diversity distribution, conservation status, conservation gaps and future research needs are provided, along with a discussion of the importance of rhizobia to the maintenance of legume diversity. Current ex situ and in situ conservation activities as well current legume uses are reviewed. In conclusion future priorities for ex situ and in situ plant genetic conservation and use of Mediterranean legumes are highlighted. All contributors look forward rather than simply reviewing past and current activities and therefore it is hoped that the identification of genetic erosion, location of taxonomic and genetic diversity and promotion of more efficient utilisation of conserved material will be enhanced.
Download or read book Understanding the Current Role of Legumes and Their Significance for Biological Nitrogen Fixation BNF in Smallholder Farming Systems of Zimbabwe written by B.T. Manenji and published by . This book was released on 2011 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major challenges faced by small holder farmers in Southern Africa and Zimbabwe in particular is poor soil fertility. Use of synthetic fertilizers is limited due to its high costs and this has led to a drastic decrease in productivity. Alternatively, farmers can incorporate legumes in their cropping systems thus improving soil fertility through biological nitrogen fixation. However, legumes are still grown at a very low scale. In order to understand the cropping patterns of legumes relative to cereals a study was carried out in Murehwa and Mudzi districts. The two areas are located in two contrasting agro ecological regions. In each district, twenty farmers were selected and based on their resource endowment, they were divided into four resource groups (RG); RG1 being the richest and RG4 being the poorest farmers. Data was collected through structured questionnaires. Comparisons of legume productivity in the different resource groups were made by evaluating areas under legumes and yields attained. These results were compared with those for maize, the major cereal crop in Zimbabwe. Constraints faced by farmers in legume production were also evaluated. In the research, analysis was also made of the agronomic practices used by farmers in different RGs to grow legumes compared to maize. The agronomic practices included labour and input allocation to different fields within the farms and legume residue use. Soil structure and fertility status for the different fields of the target farmers were determined. Total nitrogen content in different legumes was also analyzed. The marketing of the different legumes was evaluated. Results indicated that groundnut, cowpea and Bambara nut were commonly grown in the two districts while common bean and soybean were exclusively grown in Murehwa. Larger proportions of land, fertilizers and labour were allocated to maize relative to legumes. Mudzi had average areas of 0.89 ha per farm under maize, 0.09 ha per farm under Bambara nut and 0.25 ha per farm under groundnut while Murehwa had on average 1.84 ha per farm, 0.19 ha per farm and 0.15 ha per farm under the respective crops. Higher yields of both legumes and cereals were attained in Murehwa compared to Mudzi. Cereals were mostly grown in the fertile home fields while legumes were grown in mid and outfields by most farmers. The majority of the farmers applied more fertilizers to the home fields while outfields are given less attention. There were no significant differences in the quantities of fertilizers used by farmers in different resource groups in both districts. Farmers indicated that they get more profits from selling legumes than from cereals. There were no significant differences in soil structure among the different farms in the different resource groups within each district. There were no significant differences in pH, soil available N, Ca, organic carbon between the different plot types. However, the proportions of most cations decreased in the pattern; Plot type 1 >Plot type 2 > Plot type 3. There is need to promote optimal agronomic practices so as increase productivity of legumes by smallholder farmers in the two districts. Differences in input resource management on the various fields within a farm result in variation in fertility and hence differences in productivity within the fields.
