This document provides information on composting and worm farming. It begins with definitions of composting and worm farming, noting that composting is a natural process of decomposition driven by microorganisms. It then discusses the benefits of composting and worm farming such as reducing waste and improving soil quality. The document provides instructions on building compost piles and worm farms, including important principles like aeration, moisture levels, and ingredient balance. It also discusses potential problems in composting and solutions. In the end, it describes uses for finished compost and worm castings in gardening.
All you need to learn and start composting with aid of earth worms on your own.
Composting of waste to produce bio fertilizer by decomposition or by the use of earthworms called vermiculture.
What is Vermicomposting?
Vermicomposting is a simple biotechnological process of composting, in which certain species of earthworms are used to enhance the process of waste conversion and produce a better end product. Vermicomposting differs from composting in several ways (Gandhi et al. 1997). It is a mesophilic process, utilizing microorganisms and earthworms that are active at 10–32°C (not ambient temperature but temperature within the pile of moist organic material). The process is faster than composting; because the material passes through the earthworm gut, a significant but not yet fully understood transformation takes place, whereby the resulting earthworm castings (worm manure) are
rich in microbial activity and plant growth regulators, and fortified with pest repellence attributes as well! In short, earthworms, through a type of biological alchemy, are capable of transforming garbage into ‘gold’

Earthworms largely consume organic matter and give out their excreta called as casts. these casts along with other composted organic material is called as vermicompost. Vermicompost today is part of the organic farming package.
Vermiculture is the scientific process of culturing of worms in producing vermicompost. Vermicompost is nutrient rich worm castes. Worm castes is excreted product of worms which obtain in provides organic/biodegradable as a food source for worms. These vermicomposting method is very perfect for producing biofertilizers. Advantages and Disadvantages are mentioned here.

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.

Organic Waste Composter (OWC)
In any Bio-Degradable Wet Waste, 70 of the content is Water and the balance is Solid content. This is the vital principle for working with GREEN BIN. Organic Waste Composter (GREEN BIN) is a fully automatic composting machine that uses particular microorganisms to break down and decay all kinds of natural waste into manure with a
volume decrease of 85-90. The entire process is genuine and natural.
Hydraulic creators produce high-quality electricity using the power from the base machine’s hydraulic System. The Hydraulic creator is turned on by opening the hydraulic oil painting oil flux to it. A hydraulic creator is a quiet-running creator that does not need a fresh pump or motor. Installing a Hydraulic creator into a mobile machine increases the vehicle's productivity and net worth.
There is no further need for dragging big separate generators to the work Spots, Hydraulic
creator is always on board and ready for use. By installing the hydraulic creator to the mobile
machine, the operation rate of the machine increases and there is a lower need for multiple machines on the worksite. pivotal Benefits Always ready for use Saves time, space, and resources further durability Easy installation on all hydraulic systems.
Rock crushing is a process used in construction, mining, and aggregate assiduity. As the
name suggests, it involves breaking down gemstones into fine, small pieces. The process
generally involves several major pieces of the outfit. A haul loads the clincher with the large
pieces of the gemstone. The clincher cannot crush boulder-sized monuments.
There's a major distinction while copping an alternate-hand or employed tractor; a commodity like 25 to half of the expenditure is the distinction from the new backhoe. likewise, someone must be careful; though an alternate-hand excavator is cheaper it can
bring big during repairs. Hence, the total quantum of cost can make it not worth copping.
The physical check is generally done in two phases; the visual physical check and the operation or performance check. Stage I-Visual fleshly or physical examination.
The following are the effects to be checked in this stage Machine- If examining the machine, you must search around the cube of the machine for any signs of soot that comes from the bank. Any sign of soot will signify that there's a need of catching the machine. Check also for any suggestion of oil painting leakages in the machine or neglect.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

4. WHAT IS COMPOSTING AND
WORM FARMING?
Composting is not a new science, humans have been recycling waste products for
thousands of years and nature has been composting since the beginning of time.
Composting is a natural process that involves the
decomposition of organic matter. Millions of micro-organisms
drive the compost process by breaking organic matter down to
its original nutrient form. This valuable nourishment is then
returned to the soil to help improve plant growth, water
retention and the natural capacity of plants to resist disease.
Worm farming is composting with the extra help of worms. Worms help to aerate
the soil and their castings are an excellent fertiliser for the garden.
IMPORTANT NOTE
It is important to wear gloves when handling
compost to reduce the risk of infection. Avoid the
disturbance of dry compost materials as this may
release irritating spores and fine dust that could
cause respiratory problems.
2
5. WHY BOTHER COMPOSTING AND
WORM FARMING?
Australia is second only to the United States in the per capita production of waste.
Each year every Australian produces around 800kg of solid waste. In New South
Wales, an average of 65% of our household rubbish is food scraps, garden waste and
other organic matter. In the Hawkesbury, organic materials are the most common
item disposed of in residential garbage bins.** The best way to reduce our food and
garden waste is to convert it to compost.
Organic material that is deposited in a landfill breaks down in
anaerobic (without air) conditions, releasing methane and
carbon dioxide. Both of these gases are major contributors to the
enhanced greenhouse effect, which many of the world’s
scientists suggest is changing global weather patterns.
On a more local level, sending organic waste to landfill is simply
a waste. Aluminium cans, newspapers and glass bottles are
commonly separated for recycling; wherever possible organic
waste should also be recycled.
Recycling organic waste using a compost or worm farming system
will not only help the environment, the end products will
improve the structure of your soil and introduce or replace
valuable nutrients vital to healthy plant growth. You will also
save money on expensive fertilisers and other products and
increase water retention in the soil (therefore reducing your
water bill).

6. THE COMPOSTING RECIPE:
ADAM
Building a compost heap is relatively simple and can be likened to baking a cake- a
good recipe and the right ingredients are essential! There are four important
principles to remember for building and maintaining your compost (ADAM). Each of
the four principles is important on its own, but when used together they provide an
effective recipe for quickly decomposing your garden and kitchen waste.
THE RECIPE - ADAM
A - ALIVENESS
Compost is not a pile of dead, rotting rubbish. Compost is a living system in which
countless numbers of bacteria, fungi, protozoa and other critters eat their way
through your garden waste and turn it into nutrient-rich humus. To encourage
"aliveness" in your compost, place the pile directly on the ground and remember to
regularly check the air, diversity and the moisture level.
D - DIVERSITY
Diversity of ingredients is the key to a speedy and efficient decomposition process.
Diversity provides the environmental conditions and nutrients for a wide range of
organisms that will in turn provide you with balanced and nutrient rich compost.
A - AERATION
More Air = Less Smell. Air in your compost heap
ensures aerobic (air breathing) bacteria will
recycle your waste materials. If your compost heap
lacks air, anaerobic bacteria will flourish and
produce offensive gases. Regular layers of coarse
material will keep air flowing through the heap.
Turning your heap every 10-14 days and drilling
small holes in commercial compost bins can also
help aeration.
M – MOISTURE
All organisms in your pile require moisture. Any dry material should be watered
before the next layer is added. A dry compost heap will stop working; one that is
too wet will become smelly because air has been forced from the heap. The
optimum moisture content is between 50-60% (about as moist as a wrung out
sponge). If your compost heap receives full sun, particularly in the afternoon, you
will need to regularly check the heap and water when necessary.
4
7. OTHER CONSIDERATIONS
T – TIME
Composting takes time. Don’t expect your compost to be ready overnight. If you
follow the ADAM principles your final product will generally be ready after 6 - 10
weeks. A hotter compost heap will decompose faster.
T – TEMPERATURE
The micro-organisms in your compost heap produce heat. This heat is held in the
heap by the insulating properties of the bin or the compost materials.
Remembering ADAM is the simplest way to ensure your heap reaches a suitable
temperature. Adding animal manure or blood and bone can assist this process.
5
8. Nitrogen is a very important element for maintaining healthy compost and is used
by essential micro-organisms for growth and reproduction.
A lot of garden waste is dry, brown and woody. These materials are essential for
drainage and aeration in the compost heap and tend to be nitrogen ‘poor’ (low in
nitrogen). On the other hand, kitchen scraps and soft, green garden waste tend to
be nitrogen ‘rich’ (high in nitrogen). The trick to successful composting, is to feed
your compost a balance of both nitrogen ‘rich’ and nitrogen ‘poor’ materials.

11. COMPOSTING SYSTEMS
There are many methods to produce compost and a range of compost systems that
can be bought or built to produce compost.
COMPOST PILE
Choose a site and add compost materials. Maximum size should be around 1.5 x
1.5m. Heap should be turned every 10 -14 days.
Materials: No materials necessary, suitable space is needed.
Cost: Cheap, minimal cost.
Advantages: Cheap to build.
Disadvantages:
Requires regular turning, is open to scavengers and can seem
untidy.
NOTE: Placing the heap on wire mesh or inserting PVC pipes with holes, can
increase airflow.
9
12. STEEL WIRE ENCLOSURE
Materials: Star droppers/wooden stakes, wire or plastic mesh.
Cost:
Varies depending on materials used. Maximum cost is
approximately $60.
Advantages: Relatively cheap, easy to erect and move.
Disadvantages:
Difficult to access for turning and adding large volumes of compost
materials.
NOTE: Open composting systems may dry out easily, keep moist.
10
13. BESSER BLOCKS/RAILWAY SLEEPERS
Materials:
Sleepers or besser blocks as required. Old pallets also make
excellent sides.
Cost:
Varies depending on materials used. Maximum cost is
approximately $200.
Advantages:
Allows good airflow, easy access when adding materials, long
lasting.
Disadvantages: Can be costly, significant space is required.
NOTE: Can be made using old or recycled materials.
11
14. COMMERCIAL BINS
A huge range of plastic compost bins is available from hardware suppliers.
Cost:
Varies depending on design. Cost ranges from approximately $50-
$100.
Advantages: Fully enclosed, neat and easy to move.
Disadvantages:
Some bins can become anaerobic (no oxygen) which can produce
smells; bin capacity may be too small for keen composters.
NOTE: Perfect for the average householder.
12
15. BARRELS AND TUMBLERS
A range of commercial barrels and tumblers are available. Barrels and tumblers use
a tumbling action to aerate the compost- just like a clothes drier! Tumblers can
also be made using steel drums and other suitable materials.
Cost: Ranges in price from approximately $120-$500.
Advantages: Can produce compost very quickly.
Disadvantages:
Can be costly and can require more attention to produce results
than other methods.
NOTE: Turn regularly to speed up the composting process.
13
16. USING COMPOST
There are many ways to use the end product of your composting efforts. Here are
some useful ideas:
• When planting out seedlings, add some compost to provide a growing boost.
Compost can be used as a starting mix for vegetable and flower seeds. Mix
one-third sand with two-thirds compost to create a fine textured soil. Use a
sieve to separate the larger particles- these can be returned to your compost
heap to decompose further.
• Top-dress the lawn with fine compost- sprinkle a thin layer of compost on
your lawn once or twice a year to encourage healthy growth.
• Use your finished compost as a mulch to fertilise plants and garden beds. To
mulch with compost, add a depth of 5-7cm of compost to the soils around the
drip line of plants. Don’t place compost mulch directly up against the trunk of
trees or main stem of plants.
• Finished compost can be used as bedding material for your worm farm.
14
17. MAKING A WORM FARM
Worm farming is an excellent way to compost and the by-products of a worm farm
are an excellent fertiliser for your garden. Worms mix and aerate soil and produce
nutrient rich castings that help to keep our soils healthy. Worm farms are also
useful for people who live in flats or units who may not have the space to set up a
compost heap.
Worm farms are simple structures that you can either make
yourself or buy from hardware stores, nurseries and large
department stores. Check in the Yellow Pages under ‘Worm
Farms’ for a list of local suppliers.
A commercial worm farm is a neat and attractive way to
recycle food waste and comes complete with instructions and
all the materials necessary for setting it up.
HOME-MADE WORM FARMS
1. Find two stackable containers of equal size for your worm farm - old wooden
drawers, plastic crates or polystyrene fruit boxes make good farms.
2. Punch or drill some holes in the bottom of your upper container to allow
worm juice to drain to the lower container. In the lower container, make a
tap so that you are able to drain and collect the worm juice.
3. Place an up-turned empty ice-cream box in the bottom of your lower
container. This will assist any worms that fall through to the lower container
to climb back up to the top. It will also form an island for your worms and
prevent them from drowning in the worm juice.
4. Make a 10-15cm layer of bedding for your worms in the bottom of your upper
container. A mixture of aged compost, coconut fibre and shredded newspaper
makes excellent bedding. Soak the bedding in water before it is added to the
container.
5. Add your worms- you will need at least 1,000 worms to start your worm farm.
Worms from your garden are not suitable; you will need to buy suitable worms
(such as Red worms or Tiger worms) from a worm breeder.
6. Allow the worms to settle into their new home for approximately a week
before feeding them for the first time. Feed your worms to one side of the
upper container to allow a food free area for worms to roam.
7. Cover the upper container of your worm farm with a few sheets of newspaper
or a piece of hessian. This will help to keep the worm farm dark and moist.
15
18. FOOD
Worms like to eat most fruit and vegetable scraps but since worms don’t have
teeth, it is helpful to cut scraps into small pieces. Worms also like to eat:
Paper
Soil
Leaves
Crushed egg shells
ld prefer not to eat. Avoid feeding
our worms meat as it can lead to odours and may encourage maggots. Other foods
eeding your worms include:
mite or lime every few weeks to help prevent the
orm farm from becoming too acidic.
orms usually live underground where it is cool, dark and moist. Make sure your
orm farm is not in di your worm farm is
ept moist.

19. USING WORM CASTINGS
AND WORM JUICE
Worm farms produce two types of garden product- worm castings (or worm poo)
and worm juice (or liquid fertiliser).
WORM CASTINGS
Worm castings can be collected from your worm farm by light separation. Open the
lid of your worm farm and wait for the worms to burrow down. Simply remove the
top layer of worm castings and replace with a new layer of soil.
Worm castings can be used as an excellent fertiliser by applying it straight on the
garden or onto your pot plants. Worm castings can be mixed with potting soil or
sand to make a potting mix suitable for many types of seedlings.
WORM JUICE
Drain the worm juice from the lower layer of your worm farm into a suitable
container. Dilute the worm juice 1:10 with water using 1 part juice and 10 parts
water. Worm juice can be used as a fertiliser for all plants. Vegetables particularly
love it but it is also good for feeding indoor plants and garden flowers. Worm juice
can also be used as an organic spray to strengthen the immune system of your
plants. Worm juice can be stored almost indefinitely in a cool, shaded site.
