Our society needs to start composting for a sustainable living and to reduce the load on landfill. This will not only protect the environment from harmful products but also will enhance the soil quality.
Composting: A Tour of Techniques From Manure to ObscureBen Capozzi
Here's my presentation from a November 2014 public lecture on composting. I've had many requests for copies of this!
Invited by the Southside Virginia Master Gardeners Association, I pulled together material from my training as an MG, but also lots more from my certificates in Permaculture and the Soil Food Web. My goals were 1) to share enthusiasm for this eco-friendly practice, 2) take the apprehension out of the process, and 3) encourage systems-level thinking to reduce, re-use, and recycle yard waste. We can keep good biological matter and carbon out of our landfills and use their nutrients to build soil life in our own backyards.
Based on feedback afterwards, I seem to have done a pretty good job.
Harness nature’s secret to healthy, fertile soil. Everyone can take advantage of basic composting techniques to improve soil quality and reduce waste. In this class we will discuss the advantages of various composting methods, and provide you with ideas for improving your soil to produce healthier, more vigorous plants.

Composting Troubleshooting Common Issues and SolutionsTriuPhm16
Discover common composting issues and their solutions in this comprehensive guide. Learn how to troubleshoot your composting process and achieve successful results.
Compost is simply decomposed organic material. The organic material can be plant material or animal matter. While composting may seem mysterious or complicated, it’s really a very simple and natural process that continuously occurs in nature, often without any assistance from mankind. If you’ve ever walked in the woods, you’ve experienced compost in its most natural setting. Both living plants and annual plants that die at the end of the season are consumed by animals of all sizes, from larger mammals, birds, and rodents to worms, insects, and microscopic organisms. The result of this natural cycle is compost, a combination of digested and undigested food that is left on the forest floor to create rich, usually soft, sweet-smelling soil. Backyard composting is the intentional and managed decomposition of organic materials for the production of compost, that magical soil enhancer that is fundamental to good gardening. Anyone can effectively manage the composting process.
Composting is nature's process of recycling decomposed organic materials into a rich soil known as compost. Anything that was once living will decompose

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.
Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.
"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.
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.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

Composting making black gold for a sustainable living on an individual or community level
1. Composting: Making the Black Gold
for a sustainable living on an
individual or community level
Dr. Sanghamitra Kundu
2. What is Composting?
Transformation of organic matter (food wastes, dry
leaves, plant wastes, etc.) through decomposition into
a biologically humus-rich substance which aids is soil
conditioning.
Microorganisms (bacteria and fungi), invertebrates
(insects and earthworms) helps in this composting
process.
3. What materials can be composted?
Greens/wets (N)
Vegetable scraps,
fruits
Egg shells
Tea bags, tea leaves
Garden waste,
flowers, clippings
Garden trimmings
Browns/drys (C)
Dry leaves, dry plants
Shredded Paper, paper
cups/plates (without the
wax coating)
Sawdust
Coffee grounds and filters
Nut shells
Dryer lint
Pine cones
Meat, dairy products, fats, pet poop, bones, diseased plants, chemical
fertilizers/herbicide containing plants are to be avoided
4. Involves:
Collect the organic wastes (kitchen wastes, plant wastes etc.),
the nitrogen containing wastes or the wet wastes. For faster
composting process, the materials can be shred into smaller
pieces
Also collect the high carbon wastes or dry wastes viz., straw,
hay, dried leaves, wood chips, saw dust or mixture of these.
Layer the materials. First lay a layer of saw dust or wood chips.
Over it lay the wet wastes and then cover it with the dry wastes.
Water the pile. Care should be taken to maintain a proper
moisture content.
Turn over the layer for proper mixing and aeration.
Add fresh layer as it comes till approximately 2 weeks (or as
per the capacity of the composting facility) with frequent
turning
The pile should not be exposed directly to sun, wind, rain or
standing water
The procedure
5. Heavy metals are toxic to thermophilic organisms
Adequate levels of P and K are important
Optimum pH ranges between 6.5 to 7.5
Voids between particles enhance the oxygen supply
Optimum temperature range occurs between 32°to 60° C
Optimum moisture content should be 50% to 60%
The smaller the size the faster the process
Air circulation enhances aerobic decomposition, reduces foul odour
Key requirements for composting
Surface Area & Particle Size
C:N Ratio
Aeration
Nutrients
Porosity
Moisture
Temperature
pH of material
Toxic Substances
The range between 25:1 to 40:1 → efficient process
6. What happens in a compost pile?
The composting process can be divided into two main
periods:
Active composting
oPeriod of vigorous microbial activity during which readily degradable
material is decomposed as well as some of the more decay-resistant
material, such as cellulose
Curing
oFollows active composting
oCharacterized by a lower level of microbial activity and the further
decomposition of the products of the active composting stage.
oWhen curing has reached its final stage, the compost is said to be
stabilized.
7. What happens in a compost pile?
The active composting period has three temperature
ranges.
These ranges are defined by the types of micro-
organisms that dominate the pile during those
temperatures and are called psychrophilic, mesophilic,
and thermophilic.
Psychrophilic temperatures are generally defined as those
below 10⁰C
Mesophilic between 10 and 45⁰C
Thermophilic above 45⁰C.
Depending on the operation, the compost pile typically
takes from 2 to 3 days to increase beyond mesophilic
temperatures and reach the thermophilic stage of
composting
8. When is the composting complete?
The pile temperature continues to decrease or remains at a low level
The pile volume decreases to about 1/3rd the original volume
The composted materials are dark, crumbly and has an earthy odour
9. Ways of composting
Composting bins
Space friendly i.e. advantageous when space
availability is a concern
Expensive
Difficulty in turning
Has a limited capacity
10. Ways of composting
Home made
Three bins (if you have
enough garden space and
also have good amount of
garden waste)
o One for the fresh waste
o One for active decomposition
phase
o One for the curing of the
compost
Indian Khamba (Customized
& suitable for small living
spaces with not much
garden space i.e.
flats/apartments)
11. Ways of composting
Bin less pile
Just a pile with no partitions
Easy and nothing to build
Take several months to build the compost
Uncontrolled and hence there may be
pockets of non-decomposed waste
oHence risky for further usage.
13. Ways of composting
Sheet Composting
"Sheet composting" is an ideal early-fall
technique that makes use of abundant leaves.
o Removes spent plants from garden beds, layer on
kitchen scraps, shredded leaves, rotted straw, grass
clippings, and a bit of fertilizer to supply some
nitrogen. Dig or till it in, and by spring there will be
lots of earthworms and a few un-decomposed
chunks.
Sheet composting is also a very good way to
reinvigorate a garden with poor or depleted soil.
Benefits: Little effort or cost
Disadvantages:
o Takes much longer than normal compost pile
o Carbon residues can take the nitrogen from soil for
decomposition or releases nitrogen in the wrong
form in the atmosphere
14. Ways of composting
Trench Composting
Trenching is the act of burying the organic waste directly into garden soil.
Advantage:
o It enables to compost meat, grains, dairy and cooked foods in addition to other kitchen scraps.
The soil cover above the waste should be at least 30-45 cm.
Disadvantage: takes a much longer time to decompose
15. Ways of composting
VermiComposting
Product of the composting process using
various species of worms, usually red
wigglers, white worms, and other
earthworms, to create a mixture of
decomposing vegetable or food waste,
bedding materials, and vermicast.
Worms eat on food wastes which gets
converted to compost as they pass
through the worms body
16. Advantages
Environmentally responsible
Reduce waste load on landfill and sewage plants
Reduce generation of methane emissions (the most dangerous
green house gas) from landfills and lowers carbon footprint
Alternative to burning
Gives a vibrant garden devoid of chemical fertilizers
Prevent soil erosion
Enriches soil
Helps retaining moisture and suppress plant diseases and pests
Can be used for Mine reclamation
17. Additional advantages
Development of a proper waste audit system
Development of a composting Culture
Development of a closer bond with nature
Development of a sense of social responsibility
