Soil Microbiology is a new branch of soil science. There are very few books dealing with practical aspects of soil microbiology. This book aims at presenting the methodologies of soil microbial activities which have direct and indirect effects on the growth and the yield of crops. The main objective in compilation of this manual is to highlight the beneficial soil microorganisms used as bio-fertilizers. The most significant of them are Azotobacter, Azospirillum, Pseudomonas, Bacillus, Rhizobium and VA mycorrhiza. This book contains assay of soil enzymes too. This book will be useful to students of biology, microbiology and agriculture.
A book on agriculture microbiology should include a study of the occurrence of microorganisms in the soil, their activities and their role in soil processes. It is this last phase which has been studied least and where the information available is far from satisfactory in explaining what is taking place in the soil. This is due largely to the limitations of the subject which depends for its advance on botany, zoology, bacteriology, chemistry,including biological and physical, and especially upon the advance of our understanding of the physical and chemical conditions of the soil. There are various kinds of audiences to which a book on soil micro-biology may appeal. There is the scientific farmer who may search for a better understanding of the processes taking place in the soil, those processes which control the growth of his crops and indirectly influence the growth of his animals. There is the agronomist, who is interested in the fundamental reactions controlling soil fertility.This book will be useful not only for students, teachers, and researchers but also for those interested in agriculture microbiology, plant pathology, ecology, environmental science, and agronomy.
Biochemistry is the science which deals with the chemical composition, the synthesis, the degradation and interaction of compounds found in living organisms. More simply it encompasses understanding of life processes in terms of chemical phenomena. The theme of biochemistry is to correlate the molecular structures with the biological functions. Today, the growth of all other biological sciences such as biotechnology, biology, physiology, genetics, pathology, microbiology, medicine, agriculture etc. is dependent upon biochemistry. Biochemistry has an important role to play in all the life processes and technological developments in the area of food energy public health and pollution control in order to meet the requirement with the rapidly increasing world population in the years to come. Biochemistry is an experimental science.This “Biochemistry Manual” has been written to help researchers, teachers and students for proper understanding and use of the major techniques and methods employed in biochemistry.
The forest soil supports a complex of animal communities of which soil arthropods are of prime importance since they constitute the major component of soil mesofauna and are useful bioindicators of ecosystem health. Considering the important role of soil arthropods in the decomposition process and maintenance of soil fertility in the soil ecosystem, the present study investigate the ecology of soil arthropods in the sal and teak forest ecosystem of Gorakhpur, U.P., India. The book provides more information on distributional pattern of soil arthropods chiefly Acarina and Collembola followed by Symphyla, Diplura, Protura, Chilopoda, Diplopoda, Hymenoptera, Coleoptera etc. derived from different forest habitats including different depths of soil. Further, it highlights the correlation between various microclimatic conditions with the monthly fluctuations of soil arthropods in both protected and degraded forest ecosystems. We hope this book will be helpful as a base for future investigations in the field of forest ecology, soil ecology, distribution pattern of microarthropods in soil in tropical and subtropical parts of the world.
This book dealt about all the branches of Soil Science and Agricultural Chemistry namely Soil Fertility, Soil Pedology, Soil Physics, Soil Chemistry and Soil Microbiology. This book is highly useful to the under graduate students, post graduate students and Research fellows who are writing competitive examinations in agricultural sciences and also provide basic ideas and fundamental understanding about Soil Science to the various user.
This book provides a distinctive introduction to the soil fertility management knowledges and techniques required in the Biological Nitrogen Fixation. The strength of this work accrues from careful and clear Agronomic explanation and detailed coverage of all the necessary topics. It is the first known treatment in such a self-confident form. It requires no previous knowledge of microbiology, and is equally suitable for students in other disciplines needing microbiology, agronomy and soil sciences at this level.
This book is designed to provide a first hand information on Legume/Rhizobium technology to researchers, field workers, teachers and students in the areas of Microbiology, Ecology, Soil Science, Agricultural Sciences and Technology. The book comprises of five chapters. The first chapter introduces the subject matter and in chapter two a review of existing literature was made. Chapter three presented the methodology, while results and discussion are presented in chapter four and five respectively.
This book presents the details overview of weeds, its ecology, selectivity, shifting against herbicides and chemical management in wheat to the researcher, studends and farmers. We have tried best to clarify the basic of chemical weed management in wheat through complilation and consolidation of the fact, figures, methodologies, techniques and approaches. The book has been written in a simple and lucid language with suitable explanations for better understand of the under-graduate, post-graduate students and researchers in the dicipline of Agronomy, Soil Science and Soil Microbiology in particular and Agriculture as a whole.
Bangladesh needs more food production without deteriorating soil fertility & productivity.Tista Flood Plain soil in the North western region is being over exploited by the farmers to sustain their livelihood. Soil is loosing fertility, crop production capacity and organic contents, accelerating desertification in the perspective of crop production.Which deserves instant mitigation for agricultural sustainability to sustain the present and future generations with requisite amount of food, fodder,fuel and fiber.Green Manuring crops enhance crop production through amelioration of soils by increasing organic contents and nutrient up take by crops which protect the living soil from degradation. Scientific ecological studies of soil of the concerned area are indispensable for developing Environmental Management Plan through systematic approach to ascertain the favorable and sustainable soil fertility with maximizing crop production. Disclosed Soil ecology,crop quality, nutrient balance and benefit-cost ratio analyses through incorporation of green manuring crops C.juncea, S.aculeate,V.munga, V.radiata and I.sp in Fallow-T-Aman Rice and Mustard cropping Pattern are contents of this book.
No-till systems have been widely adopted by farmers in Australia over the past many years to reduce soil erosion, improve soil physical and chemical properties, conserve soil moisture and save on fuel costs. These changes in tillage practices can have a major influence on the ecology and management of weeds. This book provides information on the seed biology of important Australian weed species and underpinning knowledge of their response to tillage systems. There is also information on the effect of no-till on weed seedling emergence, seed bank persistence and herbicide behaviour.
This work is related with soil nematodes, present in the soil of fruit trees, here in this study mango and guava fruits orchards were selected, due to their more production in the mentioned area, Hemicriconemoides and Aphelenchoides are nematodes found in mango and guava trees,responsible for the less production of the fruits.This work should be helpful for the students and research scholars who want to work in the field of ecology and nematology.
