This book provides a comprehensive overview of the benefits of biofertilizers as an alternative to chemical fertilizers and pesticides.

Agricultural production has increased massively over the last century due to increased use of chemical fertilizers and pesticides, but these gains have come at a price. The chemicals are not only expensive; they also reduce microbial activity in agricultural soils and accumulate in the food chain, with potentially harmful effects for humans. Accordingly, it is high time to explore alternatives and to find solutions to overcome our increasing dependence on these chemicals.

Biofertilizers, which consist of plant remains, organic matter and microorganisms, might offer an alternative. They are natural, organic, biodegradable, eco-friendly and cost-effective. Further, the microbes present in the biofertilizers are important, because they produce nutrients required for plant growth (e.g., nitrogen, phosphorus, potassium), as well as substances essential for plant growth and development (e.g., auxins and cytokinins). Biofertilizers also improve the physical properties, fertility and productivity of soil, reducing the need for chemical fertilizers while maintaining high crop yield. This makes biofertilizers a powerful tool for sustainable agriculture and a sustainable environment.

The book covers the latest research on biofertilizers, ranging from beneficial fungal, bacterial and algal inoculants; to microbes for bioremediation, wastewater treatment; and recycling of biodegradable municipal, agricultural and industrial waste; as well as biocontrol agents and bio-pesticides. As such, it offers a valuable resource for researchers, academics and students in the broad fields of microbiology and agriculture.

This book gathers the latest findings on the microbial ecology of saline habitats, plant-microbe interactions under saline conditions, and saline soil reclamation for agricultural use. The content is divided into four main parts: Part I outlines the definition of salinity, its genesis and impacts, and microbial diversity in saline habitats. Part II deals with impact of salinity on microbial and plant life/health. Part III highlights plant – microbe interactions in saline environments, and Part IV describes strategies for mitigation and reclamation of saline soils. 

The salinization of arable land is steadily increasing in many parts of the world. An excessive concentration of soluble salts (salinity) in soils or irrigation water adversely affects plant growth and survival. This problem is exacerbated in arid and semiarid areas due to their low precipitation and high evaporation rates. In turn, poor management practices and policies for using river water forthe irrigation of agriculture crops often lead to the secondary salinization of soils.

This book gathers the latest insights into soil health and its sustainability, providing an up-to-date overview of the various aspects of soil quality and fertility management, e.g., plant-microbe interactions to maintain soil health; and the use of algal, fungal and bacterial fertilizers and earthworms for sustainable soil health and agricultural production.

It first discusses the past, present, and future scenarios of soil health, and then explores factors influencing soil health, as well as the consequences of degradation of soil health for sustainable agriculture. Lastly it highlights solutions to improve and maintain soil health so as to achieve greater productivity and sustainability without damaging the soil system or the environment.

Soil health is defined as the capacity of a soil to function within ecosystem frontiers, to sustain biological productivity, to maintain environmental quality and to promote plant, animal and human health. Soil health is established through the interactions of physical, chemical and biological properties, e.g., soil texture, soil structure, and soil organisms. Healthy soil provides adequate levels of macro- and micronutrients to plants and contains sufficient populations of soil microorganisms. As a result of the increasingly intensified agriculture over the past few decades, soils are now showing symptoms of exhaustion and stagnating or declining crop yields. Exploring these developments as well as possible solutions based on holistic and sustainable approaches, this book is a valuable resource for researchers in the area of soil and environmental science, agronomy, agriculture, as well as students in the field of botany, ecology and microbiology.

Plants growing in the natural environment battle with a variety of biotic (pathogens infection) and abiotic (salinity, drought, heat and cold stresses etc.) stresses. These physiological stresses drastically affect plant growth and productivity under field conditions. These challenges are likely to grow as a consequences of global climate change and pose a threat to the food security. Therefore, acquaintance with underlying signalling pathways, physiological, biochemical and molecular mechanisms in plants and the role of beneficial soil microorganisms in plant’s stress tolerance are pivotal for sustainable crop production. This volume written by the experts in the stress physiology and covers latest research on plant’s tolerance to abiotic and biotic stresses. It elaborates on the potential of plant-microbe interactions to avoid the damage caused by these stresses. With comprehensive information on theoretical, technical and experimental aspects of plant stress biology, this extensive volume is a valuable resource for researchers, academician and students in the broad field of plant stress biology, physiology, microbiology, environmental and agricultural science.
