Soil Microbiology
H.A. Modi
Social structure has a significant influence on erosion, water intake, and crop growth. A stable granulated soil will permit rapid water uptake, drainage, aeration and beneficial microbial activity, whereas a dispersed or compact soil has a low infiltration rate Crops grow more luxuriantly in fertilized, well-aerated, drained and granulated soils. The most important factors in maintaining or improving the granulation of soils are the presence of microorganisms and their decomposition products. Microorganisms play a very important role in agriculture. They are useful in maintaining soil texture and fertility. So, study of soil Microbiology is very important for successful practice of Agriculture.
The present book covers various aspects of soil science and role of various microorganisms as biogeochemical agents for conducting various biogeochemical cycles and thereby contributing for enhancement of soil fertility.
Contents of the book include:
Basic Concepts of Soil • Physical Properties of Soil • Chemical and Mineralogical Properties of Soil • Microbial Flora of Soil • Soil Organic Matter and Humus • Microorganisms as Biogeochemical Agents • Cycling of Carbon, Hydrogen and Oxygen • Nitrogen Cycle • Sulphur Cycle • Phosphorus Cycle • Iron Cycle • Microbial Transformation of Potassium • Microbial Transformation of Manganese • Microbial Transformation of Other Minerals • Microbial Ecology and Associations
The present book attempts to offer basic concepts of all the essential components of soil microbiology used for agriculture study purposes and should prove of help to all students and professionals engaged in agriculture study and practices. This book will prove of great help to students Pursuing U.G. and P.G. courses in Agriculture and Veterinary Sciences and technology, food science and technology as well as other basic science courses (Microbiology, Biochemistry, Biotechnology, Chemistry, Environmental Sciences) where this subject forms a part of its applied biotechnology curricula. ..more

Soil Nutrient Management for Sustaiable Agriculture
A. Singh
The importance of soil nutrient management for sustainable agriculture has been widely recognized. Soil is the reservoir nutrients and half of the elements in the periodic table are being uptake from the soil by the plants but of these, only sixteen elements are essential. A soil with a Ph of 6.5-7.5 with adequate soil organic matter (about 2 to 4%) will help supply many of these nutrients; however, additional nitrogen, phosphorus and potassium are usually needed for good yields. There is increasing trend of nutrient imbalance in the soil; evident from the fact the amount of nutrient removed from the soil is more than the quantity added in the soil. This nutrient imbalance is called nutrient mining and nutrient mining resulted in poor soil health. Nutrient availability depends not only on soil nutrient store but also on the favourable soil conditions as soil reaction, physical and biological properties. Sound nutrient management is prerequisite for enhancement & maintenance of soil productivity, sustainability of agriculture.
This book contains 14 chapters on diverse vital aspects of soil management. The topics covered are role of biofertilizers, nutrient management perspectives, organisms in the soil, soil quality indicators-methods, allelopathy in soil management, services rendered by Arbuscular Mycorrhizal fungi, green manuring for improving soil fertility, role of customized fertilization for soil health and sustainability, conventional/instrumental vis a vis rapid methods of soil quality analysis, climate change and nutrient management, soil acidity and its sustainable amelioration in India, utilization of distillery spent wash in agriculture. The purpose of the process documentation is to pool the scattered information related to sustainable soil management in a book form with the help of expert academician across the country. Authors have tried level best to cater the needs of the students, extension functionaries and policy planners on the significant aspects of soil nutrient management for ensuring long term sustainability for meeting the requirement of future generations. This book may be used as reference book for future use in improving overall soil productivity. ..more

Indian Forests-Soil, Water and Bio-environment Conservation
Sheelwant Patel
Indian Forests—Soil, Water and Bio-environment Conservation—deals with the soil degradation in forests from a practising forester’s viewpoint. Most past practices believed civil engineers’ gravity structures as the panacea for the problem. This book proceeds with a different premise—earth reinforcement through root systems of vegetation best protects soil and conserves water. In elaborating this, it presents a simplified picture of Indian forest types and characteristics like soil formation, soil texture, soil organisms, etc.
For the first time, it presents a cross profile of forest vegetation across the country connecting it with prominent civil locations. Among various degrading factors, it deals with forest fires, over-grazing and different forms of soil erosion. For the first time, it flags faulty disposal of rainwater along hill roads as a menace to soil degradation. It classifies shifting cultivators in three categories—solely dependent, partially dependent and marginally dependent—probes the issue in depth and advocates, for the first time, differential treatment for them. A full chapter on landslides analyses causative factors—geomorphological, seismological, hydrological—in detail and provides the latest techniques to handle the problem. Another chapter on ameliorative soil and water conservation measures views the issue from a tree man’s point of view. Vegetative tools of foresters display their full potential here. This chapter, too, includes many firsts—jhora training in meandering streams, municipal watershed management and concept of infiltration belts for ground water recharging. Yet another chapter provides recent advances—root trainer nurseries, geo-textiles as tools of soil conservation and hydro seeding and hydro mulching as techniques of slope reclamation.
The last chapter on peoples’ participation views the whole issue from a sociologist’s viewpoint. There are many firsts in this chapter, too, —vision of stakeholders; distributive justice and people’s participation; co-operative behaviour in view of effective communication, super ordinate goal, coalescing of groups, risk of initiator; criterion for selection of success indicators; monitoring of achievements through response indicators, habitat indicators, stress indicators, institutional process indicators, etc.
Many of the methodologies described in this book come directly from adaptive field applications of various conservation principles and practices developed in other parts of the world.
A must-read book for every conservationist. ..more
