Phosphate is an essential mineral to all plants, and its availability in soils is an increasing challenge for agriculture. Phosphate is abundant in soils but its biological availability is often low due to the complexes that it forms with soil minerals and compounds. The biological availability of Phosphate is further reduced in acidic soils, which represent approximately 40% of earth’s arable agricultural lands. Agricultural systems compensate Phosphate deficiency with fertilizers coming from the mining of rock phosphate, which is estimated to exhaust within the next 50 years. For these reasons, Phosphate limitations in natural and agricultural ecosystems is going to become a global problem, and we urgently need to better understand how plants respond to Phosphate deficiency.
The omnipresence of diverse microorganisms in the environment is valuable in many ways. Their presence in the vicinity of plants benefits as a result of positive plant-microbe interaction. Phytostimulating microorganisms or plant growth-promoting microorganisms (PGPMs) are a certain group of microbes that includes rhizobacteria, endophytes, actinomycetes, fungi, arbuscular mycorrhizal fungi, etc. They are colonized in different parts of plants (as endophytes) or the close contact outside the plants’ root-surface (rhizosphere and rhizoplane) attracted by certain plant exudates or secondary metabolites for nutrition. In return, PGPMs directly or indirectly assist their host plants by secreting plant growth-promoting substances, increase nutrient bioavailability of insoluble or less-soluble compounds in soils, and also confronts invading phytopathogens. A major group of these microorganisms takes an active part in soil metal bioremediation, an essential concern in the current scenario for the reclamation of metal-contaminated agricultural fields.
This open access book shows some of the highlights presented at the XV Ibero-American Congress of Mechanical Engineering. The papers explore the forefront of Mechanical Engineering, containing research into fluid mechanics, energy systems, tribology, materials science, robotics, mechatronics, biomechanics, instrumentation, thermodynamics, and mechanical sustainability.
In order to feed the world, global agriculture will have to double food production by 2050. As a result, the use of soils with fertilizers and pesticides in agronomic ecosystems will increase, taking into account the sustainability of these systems and also the provision of food security. Thus, soil ecosystems, their health, and their quality are directly involved in sustainable agronomical practices, and it is important to recognize the important role of soil microbial communities such as mycorrhizal fungi, their biodiversity, interactions, and functioning. Soil ecosystems are under the threat of biodiversity loss due to an increase of cultivated areas and agronomic exploitation intensity. ...
This book is a critical resource for understanding the relationship between gender, social policy and women’s activism in Latin America, with specific reference to Chile. Latin America’s mother-centered kinship system makes it an ideal field in which to study motherhood and maternalism—the ways in which motherhood becomes a public policy issue. As maternalism embraces and enhances gender differences, it has been criticized for deepening gender inequalities. Yet invoking motherhood continues to offer an effective strategy for advancing women’s living conditions and rights, and for women themselves to be present in the public sphere. In analyzing these important relationships, the contributors to this volume discuss maternal health, sexual and reproductive rights, labor programs, paid employment, women miners’ unionization, housing policies, environmental suffering, and LGBTQ intimate partner violence.
This is the first anthology to explore the fertile intersection of dance and political studies. It offers new perspectives on the connections of dance to governmental, state and party politics, war, nationalism, activism, terrorism, human rights, political ideologies and cultural policy. This cutting-edge book features previously unpublished work by leading scholars of dance, theatre, politics, and management, alongside renowned contemporary choreographers, who propose innovative ways of looking at twentieth- and twenty-first-century dance. Topics covered range across the political spectrum: from dance tendencies under fascism to the use of choreography for revolutionary socialist ends; from the capacity of dance to reflect the modern market economy to its function in campaigns for peace and justice. The book also contains a comprehensive introduction to the relations between dance and politics.
This is the first book to present the idea of using Industry 4.0 and smart manufacturing in the microalgae industry for environmental biotechnology. It provides the latest developments on microalgae for use in environmental biotechnology, explains process analysis from an engineering point of view, and discusses the transition to smart manufacturing and how state of the art technologies can be incorporated. It covers applications, technologies, challenges, and future perspectives. • Showcases how Industry 4.0 can be applied in algae industry • Covers new ideas generated from Industry 4.0 for Industrial Internet of Things (IIoT) • Demonstrates new technologies invented to cater to Industry 4.0 in microalgae • Features worked examples related to biological systems Aimed at chemical engineers, bioengineers, and environmental engineers, this is an essential resource for researchers, academics, and industry professionals in the microalgae biotechnology field.
Dance, Human Rights, and Social Justice: Dignity in Motion presents a wide-ranging compilation of essays, spanning more than 15 countries. Organized in four parts, the articles examine the regulation and exploitation of dancers and dance activity by government and authoritative groups, including abusive treatment of dancers within the dance profession; choreography involving human rights as a central theme; the engagement of dance as a means of healing victims of human rights abuses; and national and local social/political movements in which dance plays a powerful role in helping people fight oppression. These groundbreaking papers--both detailed scholarship and riveting personal accounts--encompass a broad spectrum of issues, from slavery and the Holocaust to the Bosnian and Rwandan genocides to the Israeli-Palestinian conflict; from First Amendment cases and the AIDS epidemic to discrimination resulting from age, gender, race, and disability. A range of academics, choreographers, dancers, and dance/movement therapists draw connections between refugee camp, courtroom, theater, rehearsal studio, and university classroom.
Identifying, interpreting, and managing soil constraints are major challenges, especially when multiple constraints occur in the same soil at various depth zones. Although amelioration tools and strategies are available to manage some of these constraints, field adoption of these technologies is a major challenge to the farming community. Soil Constraints and Productivity helps in identifying and understanding soil constraints, focusing on management practices to alleviate problems associated with these restrictions, and their impacts on crop productivity. Soil Constraints and Productivity aims to: Describe various strategies suitable for mitigating soil constraints Provide data on cost-benefit analysis of managing soil constraints Provide case studies of managing soil constraints to increase productivity Soil is essential for the doubling of major grain production proposed to be necessary to avoid major food security collapses in the future. This book will be a key resource for soil and environmental scientists, farmers, students majoring in agricultural and environmental sciences, and crop consultants.
This book puts an updated account on functional aspects of multiphasic microbial interactions within and between plants and their ecosystem. Multipronged interaction in the soil microbial communities with the plants constitute a relay of mechanisms that make profound changes in plant and its micro-environment in the rhizopshere at physiological, biochemical and molecular levels. In agro-ecological perspectives, such interactions are known to recycle nutrients and regulate signalling molecules, phytohormones and other small molecules that help plant growth and development. Such aspects are described deeply in this book taking examples from various crop plants and microbial systems. Authors de...
