Book Description
This volume examines the interactions between plants and microorganisms located on plant surfaces, exploring their possible biotechnological applications. Interactions of microbial communities with plants are illustrated by experimental studies of typical symbiosis. Topics include signaling within a symbiosis, molecular differences between symbiotic and pathogenic microorganisms, and the role of microorganisms in the development of plants.

Book Description
The use of organic residues as a means of maintaining and increasing soil fertility is of long-standing. This tradition has been somewhat neglected since the introduc tion of mineral fertilizers at low cost. More and more farmers and scientists are now showing renewed interest in the proper and effective use of org~tnic residues, composts and other recycled organic additives. The role and function of organic amendments in modern agricultural systems have become topics of major interest in the scientific and agricultural communities. Research work on residue disposal has provided new concepts on the interaction between organic components and soils as well as new handling technologies (e. g. pelletizing of organic residues). The trend to conserve energy has led scientists to study the minimal tillage system, to find ways of replacing conventional inorganic fertilizers with natural organic prod ucts or microbial preparations, and to develop new composting methods. The drive to achieve higher yields in commercial greenhouse farming has led to a search for optimum substrates as growth media and for improved management techniques. This has led to the introduction of organic substitutes for peat, nota bly those originating from agricultural wastes. Another important aspect is the current interest in organic farming, where use of synthetic chemicals is avoided or prohibited. An increasing percentage of the population in highly developed countries is willing to pay premium prices for food produced on soils where inorganic fertilizers and other agricultural chemicals have not been used.

Book Description
The book titled “Microbiome and Plant Nutrition꞉ A Roadmap Towards Sustainable Agriculture” is expected to direct many emerging research pathways needed at local and global levels for sustainable agricultural package and practices. This volume incorporates thirteen seminal chapters on issue based research and their practical applications covering latest information and progress in different areas of microbial supplemented crop nutrition for sustainable agriculture. The book highlights the frontier issues and applications of plant‐microbe interaction in crop nutritional strategy with topics like System biology of plant microbe interaction, Plant growth‐promoting rhizobacteria꞉ a context for sustainable agriculture, Plant growth‐promoting endophytes꞉ a context for sustainable agriculture, The role of the mycorrhiza in nutrient uptake, Plant nitrogen, phosphorus and sulphur nutrition꞉ a microbial perspective, Carbon and nitrogen turnover in soils and plant rhizo‐deposition, Root exudates꞉ a link to plant‐microbe nutritional interactions and insight into the metabolic and nutrition network pathway of plant‐microbe interaction, Commercialization perspective of bio‐stimulants for sustainable agriculture, Interconnection of plants with microbiomes in changing climate꞉ a functional extension of the host and heavy metal dynamics in rice soil꞉ an alleviation through microbial intervention approach. This book will be very useful for the scholars, biotechnologists, agricultural scientists, plant nutritionists, researchers, teachers and students in the emerging field of soil‐microbiome and plant nutrition dynamics in the resilient climatic agriculture era.
