Substances containing carbon are organic matter.
Soil organic matter consists of decomposing plant and animal residues.
It also includes substances of organic origin either leaving or dead.
Soil formation or pedogenesis is the combined effect of human impact on the environment, physical, chemical and biological processes working on soil parent material.
Soil fertility is the backbone of agriculture systems and plays a key role in determining food quantity and quality. The intension of soil fertility management is to improve soil buffering capacity and to reduce soil degradation. Soil health is fundamental for a healthy food production. It provides essential nutrients, water, oxygen and support to the roots, all elements that favor the growth and development of plants for food production. Now the Indian population is 1.37 billion (Census India gov.in) Land area availability is 3.287 million km2. Net cultivable area is 143 million ha. Degraded land in India around 141 million ha. Per capita land availability is 0.3 ha per farmer (Indian express Nov 6,2009). Food grain supply 234.0 million tons, food grain demand 236.2 million tones (Praduman Kumar et al.,2016). In the year 2019 Global Hunger Index(GHI), India ranks 102nd out of 117 qualifying countries. With a score of 30.3, India suffers from a level of hunger that is serious (Global Hunger Index Organization). Nearly 1 billion people around the world suffer from hunger. Soil management is important, both directly and indirectly, to crop productivity, environmental sustainability, and human health (Mittal et al., 2008). To achieve future food security, the management of soils in a sustainable manner will be the challenge, through proper nutrient management and appropriate conservation practices. Such as maintain soil organic carbon, effective utilization of natural resources, use of non-monetary input like LEISA etc., will be the better option to fulfils the ever-growing population’s food and nutritional security.

Soils are complex mixers forming the skin of the earth's surface. Soil is a dynamic layer in which many complex chemical, physical and biological activities are going on constantly. Soils become adjusted to conditions of climate, landform and vegetation, and will change internally when those controlling conditions change. Soils are products of weathering. Soils play a dominant role in earth's geomorphic processes in a cyclic manner. The characteristics of soils are very essential for several reasons. This module highlights these characteristics.
This presentation was delivered at the National Conference on Botany and Agriculture and is aimed to draw the attention of the audience towards the growing problem of agri. waste management in India.
The arrangement of these horizons in a soil is known as a soil profile. Soil scientists, who are also called pedologists, observe and describe soil profiles and soil horizons to classify and interpret the soil for various uses. Soil horizons differ in a number of easily seen soil properties such as color, texture, structure, and thickness.

The Complete Book on Organic Farming and Production of Organic Compost (2nd Revised Edition)
Organic farming is a technique that entails growing plants and raising animals in a natural environment. To preserve soil fertility and ecological balance while minimising contamination and waste, this method employs biological materials while avoiding synthetic substances. To put it another way, organic farming is a form of farming that involves growing and caring for crops without the use of synthetic fertilizers and pesticides.

What are the benefits and impacts of Organic Biopesticides useShivaniPadole
Organic Biopesticides are certain types of pesticides derived from such natural materials as bacteria, plants, animals, and certain minerals. For example, canola oil and baking soda have sendriya pesticide applications and are considered Biopesticides. Biopesticides are mostly inherently less toxic than conventional pesticides. Biopesticides normally affect only the target pest and closely associated organisms, in contrast to broad spectrum, conventional Organic pesticides that may affect organisms as dissimilar as birds, insects and mammals.
What are the Organic Farming Bio PesticidesShivaniPadole
Bio-pesticides are natural derivatives that are made by using biological raw materials, sourced from animals, plants, microbial organisms, and minerals. The Biopesticides are tailored to be used in liquid and dry formulations and are highly efficient in killing pests, weeds, and other pathogens. The adoption of Biopesticides is witnessing modest growth as Biopesticides do not contain hazardous and toxic chemicals in their structure. There is a few amount of use of inputs, like fungicides, herbicides, and organic pesticides for agriculture. It ensures crop health and secures it from pests and insects.

WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes. This research builds off our first guide for food service, now with industry experience and insights from nearly 350 academic trials.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
