Methods and procedures for the qualitative characterization and quantitative analysis of different constituents of soil organic matter are presented in this Chapter.

20.1. Moisture

The soil sample should be in an air-dry condition after mixing, sieving and grinding. When stored in a moisture-tight container, the free H₂O content should not vary appreciably during storage. While most determinations can be done on air-dry samples, for certain purposes such as obtaining summation values, a moisture content value is required.

Introduction 
Inclusive education means including all children in the same classrooms, in the same schools. It means real learning opportunities for groups who have traditionally been excluded – not only children with disabilities, but speakers of minority languages too. The school and classroom operate on the premise that students with disabilities are as fundamentally competent as students without disabilities. Therefore, all students can be full participants in their classrooms, in the local school community and in the societies they live in. Much of the movement is related to legislation that students receive their education in the least restrictive environment (LRE). This means they are with their peers without disabilities to the maximum degree possible, with general education the placement of first choice for all students (Alquraini & Gut, 2012). Inclusive education in India has evolved significantly over time. Initially, education for children with disabilities was largely segregated, with specialized institutions being the primary option. The shift towards inclusion began gaining momentum in the late 20th century, influenced by global movements and national policies. Key milestones include the 1992 National Policy on Education, which emphasized inclusive practices, and the 2009 Right to Education Act, which mandated free and compulsory education for all children, including those with disabilities. Recent initiatives have focused on improving accessibility, teacher training and integrating students with diverse needs into mainstream classrooms, reflecting a growing commitment to equitable educational opportunities for all. Contemporary inclusive education in India is characterized by a growing commitment to integrating students with diverse needs into mainstream schools, supported by various policies and initiatives. The 2016 Rights of Persons with Disabilities Act and the 2020 National Education Policy underscore the importance of inclusive practices, advocating for accessible infrastructure, specialized training for educators, and individualized support for students. Despite these advancements, challenges remain, including inadequate resources, a shortage of trained teachers, and varying levels of implementation across different regions. Efforts are ongoing to address these issues, aiming to create an educational environment where all students, regardless of their abilities, have the opportunity to succeed and thrive. The emerging importance of an inclusive education system in India reflects a growing recognition of diversity and equality in the educational landscape. This shift is driven by the realization that inclusive education not only promotes social justice but also enhances academic and social outcomes for all students. As India progresses towards a more inclusive society, there is increasing emphasis on

Fertility of a soil can be assessed by analyzing various available nutrients present in the soil. Fertilizer recommendations for various crops and cropping sequences can be made on the basis of fertility status of a soil. Besides this, problematic soil can be ameliorated on the basis of soil test values. Among the various steps of soil testing programmes, soil sampling is the most vital step.

Throughout human history, people across the globe have sought to understand and predict the ever-changing skies. From the scorching deserts of North Africa to the lush rainforests of South America, and from the snow-capped Himalayas to the vast Australian outback, ancient cultures developed unique methods to forecast the weather. These traditional knowledge systems, often passed downthrough oral traditions and  storytelling, reflected the specific environmental contexts, mythological beliefs, and spiritual practices of each community. In ancient China, royal astronomers meticulously recorded weather patterns and planetary movements to guide agricultural planning and imperial decisionmakingIn Greece, philosophers like Aristotle and Theophrastus wrote extensively on weather signs and forecasting methods. In Africa, tribal communities observed animal migrations and plant behaviors to anticipate seasonal changes. Native American tribes used lunar cycles and star constellations to predict weather patterns, while ancient Indians studied the movements of planets and nakshatras (lunar mansions) to forecast monsoon rains.

Pulses, grown on marginal and poor soils under low input management with very low yields, are the integral part of dryland farming systems and cover 12.8% of the total cropped area in Andhra Pradesh. There are no pulse based cropping systems in the state and they are only component crops of cereals or commercial based cropping systems as intercrops or catch crops in between two main crops or as sequence crops after exhaustive cereal or commercial crops raised on residual fertility and receding soil moisture. The important pulse crops grown are Chickpea, Pigeonpea (Redgram), Mung bean (Greengram) and Urd bean (Blackgram) which contribute to 97.7% of total pulse production in the state. Pigeonpea is mostly grown as intercrop under rainfed conditions with crops like sorghum, maize, castor, cotton etc. It is also grown as sole crop and at times, pigeonpea is intercropped with greengram/ blackgram.

Introduction

The sun is an abundant source of solar energy (average value on horizontal surface 6 kW m^-2 day^-1), which is freely available. This huge source of energy is non-polluting and inexhaustible in nature. It has the potential of supplementing the conventional energy sources to a great extent. There is acute shortage of conventional energy sources, which affects the overall development. Work on the utilization of such a huge, non-polluting and everlasting energy source has been carried out at CAZRI, Jodhpur for various domestic, industrial and agricultural applications in order to supplement the energy demand. This includes the development of a lot of solar thermal devices, such as, solar still, solar dryer, solar cooker, animal feed solar cooker, solar candle device and cool chamber. The details of some of these devices are given as following.

Animal husbandry

Animal husbandry is the branch of science concerned with the care and breeding of domestic animals such as cattle, hogs, goat, sheep and horses.

India supports nearly 20% of the world livestock and 16.8% human population with a land area of only 2.3%. India leads in cattle and buffalo population and has world’s second largest goat and third largest sheep population. As per the 19^th Livestock census (2012) cattle (191 millions), buffalo (109 m), Sheep (65 m), goats (135 m), pigs (10.29m), camels (0.4 m) and poultry (729.2 m) population was reported in India. The total livestock population has decreased by about 3.33% over the previous census. India’s milk production increased from 43 million tonnes in 1983 to 155.5 million tonnes in 2015-16 (annual growth of 6.27%) and stands first in milk production in world.. The egg production is around 82.93 billion during 2015-16. The per capita availability is around 66 eggs per annum. The poultry meat production is estimated to be 3.26 million tonnes. Wool production (43.6 million Kgs) and meat production is 7.0 million tonnes in 2015-16.

Type and Potential of Organic Residues

A number of diverse sources of organic materials are available for recycling in agriculture. These are mostly of plant origin and recycled either directly or after having being used as feed or food by animals and humans. In view of high organic content and mineral nutrients in the biomass, these are considered as valuable inputs to improve the soil fertility and crops production. Organic resources are low cost inputs but are valuable based on its potential for nutrients and organic matter content.

Attractive Features of Organic Resources

• Organic matter is the basic resource of several essential plant nutrients.

• It buffers the effects of pH dependent changes on nutrient availability.

• They are generated close to their use.

• They are renewable as they are generated regularly.

• With increasing demand for increasing food production, the potential of organic resources is expected to rise.

• Farmers are familiar with organic resources from time immemorial.

SYNOPSIS

Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt. Many individuals do not consume ASF or consume little ASF by either personal choice or necessity as ASF may not be accessible or available to these people. Animals are used as food either directly or indirectly by the products they produce. Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt.

5.1 INTRODUCTION

One of the generalizations that can be made about soils is that the particles of which they are composed together have a nett negative charge. There are exceptions: for example, some iron- and aluminium-rich tropical soils can attain a positive charge at low enough pH, but such cases are rare. It is nonetheless a fact that most anions are held strongly by the soil complex, and it is the purpose of this chapter to look at some of the reasons why this is so. Historically, the impetus to research in this area has largely been the practical necessity to understand the behaviour of applied phosphate fertilizer, and it is some indication of the complexity of the problems involved that, even after decades of effort by soil chemists and agronomists, this understanding is still far from complete. The reason for this is partly that the soil surfaces themselves are, as has been described by Greenland and Mott (1978) in the companion volume, the product of a ‘dirty’ environment. This generally means that phosphate added to the system has to exchange on sorption with an inadequately characterized suite of anions presorbed on ill-defined surfaces. There are also in the case of phosphate, possibilities of simultaneous precipitation. Faced with these problems, the trend in the literature over the past ten years or so has been to investigate in detail the physical chemistry of the sorption of anions onto simple surfaces which are fairly well understood, in the expectation that this will lead to ultimate comprehension of behaviour in the natural system. The results of many relevant experiments have only recently been published, and so some parts of the account are still at the discussion stage in the literature. This is especially true of phosphate, which looks destined to be a joker in the anion pack for some time to come.

1. Introduction Ayurvedic texts like Charak Samhita and Sushruta Samhita, have described millets as the staple food useful in managing diabetes mellitus (Sachan Kumar, 2004). Based on the experience of eating these millets for time immemorial, there exists also a strong traditional knowledge about health benefits associated with them. For example, as per an adage in the state of Karnataka, India: “Those who eat rice will grow as a light weight; their body being just like that of a bird; those who eat Jowar will become as strong as a wolf but those who eat Ragi (millets) will be the strongest of them all, plus they would be free from illness (‘nirogi’ in Sanskrit)”! Certain studies from literature refer nutraceutical character of millets, especially, Kodo and Kutki, which in our opinion should help mankind in eradicating malnutrition and hunger while ensuring sustainable supply of food.

Millets have immense potential of providing nutritional security worldwide and play a pivotal role in food and nutrition economy. The nutritional aspects of millets are comparatively superior from the widely consumed cereals across the globe. With the presence of various essential macro nutrients millets are also enriched with the goodness of micro nutrients as minerals, vitamins and possess various bioactive compounds that portray several health benefits. The nutritional attributes of the millets are accompanied with several antinutritional factors such as tannins, phytates, saponins, trypsin and amylase inhibitors etc. that limit the bioavailability of the essential nutrients and minerals in these wonder grains upon consumption.

ABSTRACT

Serious infections caused by bacteria that have become resistant to commonly used antibiotics have become a major global healthcare problem in the 21^st century. Antibiotic resistance, initially a problem of the hospital setting associated with an increased number of hospitals acquired infections usually in critically ill and immuno-suppressed patients, has now extended into the community causing severe infections difficult to diagnose and treat. In hospitals, most common resistant bacteria include methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci and gram-negative rods including Enterobacteriaceae and Pseudomonas aeruginosa. Vancomycin intermediate and resistant S. aureus, represent a new treatment challenge. In the community, penicillin and macrolide-resistant pneumococci developed several decades ago and are now present all over the world. More recently, communityacquired methicillin-resistant S. aureus has become a problem in several countries causing skin infections but also severe diseases. The molecular mechanisms by which bacteria have become resistant to antibiotics are diverse and complex. Bacteria have developed resistance to all different classes of antibiotics discovered to date. The most frequent type of resistance is acquired and transmitted horizontally via the conjugation of a plasmid. In recent times new mechanisms of resistance have resulted in the simultaneous development of resistance to several antibiotic classes creating very dangerous multidrug-resistant (MDR) bacterial strains, some also known as ‘‘superbugs’’. In many cases the use of antibiotics is unnecessary or questionable. The indiscriminate and inappropriate use of antibiotics in outpatient clinics, hospitalized patients and in the food industry is the single largest factor leading to

Introduction

Honey bees are the most fascinating creature found in the nature and are very closely associated with our cultural heritage. They have been evolved with structural perfection and behavioral instinct to render their service as the best pollinator and enable to realize the potential yields of several cross pollinated crops under various agro-ecological situations. They are indispensable for human survival. The words of the great scientist Albert Einstein quoted below is very pertinent in this context “If the bee disappeared off the surface of the globe, then man would only have four years of life left. No more pollination, no more plants, no more animals, no more man”.(Thakur, 2011). Thus, starting from honey hunting since time immemorial to traditional bee keeping and its present transformation to scientific bee keeping has been a continuous endeavor of human for harnessing both direct and indirect benefits from bee keeping activities. Bee keeping has been a very popular agro based enterprise which does not compete with any resource of farming system rather acts as an integral component of Integrated farming system. Now-a-days it has not only attracted the attention of a diverse group of people, administrators and institutions for various purposes but also it has been the point of attraction of the rural poor and youth for their livelihood improvement.

Introduction

Under the present scenario of growing human population and shrinking land and water resources for agriculture, expanding abiotic and biotic stresses, increasing genetic erosion; relentless efforts are needed to enhance the plant productivity as well as quality of produce. In fact, improvements in agricultural production as well as food and nutrition conditions depend on land, water and energy resources, which are, undoubtedly, limited and depleting at a rapid pace.

Biotechnological innovations in conjunction with conventional technologies have opened new frontiers in agriculture thereby offering exciting opportunities for increased sustainability and profitability in agriculture. Thus, biotechnological tools complement (rather than replace) the traditional methods used to enhance the agricultural productivity to cater to the needs of third world agriculture (Swarup and Srivastava1990, Rao et al. 1996).
