rice harvest and hay are piled in the open.
The mandala is still popular on the countryside. The hay is utilized for roughage, mulch,
compost, including fuel. (Acrylic

I. Introduction
Everything on earth and in the universe undergoes a cycle, a beginning
and an end, and in between a period of growth, stability and senescence Yet no
cycle could succeed unless it is part of an interrelationship with and among
other cycles in the biological and physical world, each lending a vital role
aimed at a holistic and perpetual oneness apparently designed by an
unknown hand.
Cycle and recycle is the principle
key to homeostasis that maintains the integrity of the biosphere, and the whole
Planet Earth . Everything is tuned to a cycle - the passing of seasons,
alternation of generations, food web and food chain, “natural” clocks,
ecosystem seres, etc. And none of these can work without being part of a
complex pattern of inter-relationships.
II. Recycle
Farm Wastes
1. The moist common materials for composting in
the farm are rice straw, peanut and mungo hay, banana stalk, corn stover, Azolla,
ipil-ipil, wood and coconut shavings, livestock wastes and chicken
droppings, pond scum, water lily and weeds.
2. Actually we get so little of the fertilizer
value we put into a crop as shown by this typical fertilizer efficiencies.
·
30 to 60 % for N,
·
10 to 35 % for P, and
·
15 to 30% for K.
3. There are more nutrients removed from the
soil that go into the straw than the grain. Here is a comparison. (Grain versus
straw, kg nutrient/MT)
·
Nitrogen: 10.5 - 7.0
·
Phosphorus: 4.6 – 2.3
·
Potassium: 3.0 –
17.5
·
Magnesium: 1.5 – 2.0
·
Calcium: 0.5 -
3.5
4. Rice straw contains 85-90 percent of
potassium (K) of the biomass. Thus much
greater amounts of K must be applied to maintain soil supply where straw is
removed.
5. Small
Water Impounding Projects (SWIP) are popular in many parts of the world
where water is seasonal. Bigger ones can even generate electricity for
locality.
6. Recycle crop residues to raise livestock. Our
Philippine carabao is perhaps the most efficient feed converter. Of the
ruminant animals it has a digestive system that can extract sufficient
nutrients from roughage, enabling them to survive long dry spells.
7. Recycling with poultry makes use of farm
by-products such as rice and corn bran, and reduces wastage in crops. Upgraded native
chicken are more resistant than pure breeds, and are more resistant to pest and
unfavorable weather. These chickens thrive on palay and corn; they forage in
the filed, and glean on leftovers. They
are therefore, more economical to produce, tastier and free of antibiotic
residues and artificial growth hormones.

Sasso
Chicken
This
type of chicken is a crossbred of our own native breed with chicken
from Southern France from which it got its name. Teresa Farms, Rizal
owned and managed by Mr. Bobby Inocencio. 
A Herd of Philippine Carabao
Carabaos beat the long hot summer along streams where they wallow in herd. (San Marcelino, Zambales)
8. Recycling with goats makes use of farm
by-products and plants. Practically anything that grows in the field is food for
goats, be it weed or crop. Thus they are very destructive to plants that they
must be restrained in pens or tethered.
9. Recycle wastes from market and kitchen
Vegetable trimmings, and waste from fish and animals require efficient
collection, segregation and processing into biogas and organic fertilizer.
10. Recycling leads to the development of many
products. Fruits in season that otherwise go to waste are made into table wine
of different flavors. Typhoon or drought affected sugarcane make excellent
natural vinegar and molasses.
11. Another recycling project is vermiculture,
the culture of earthworms for game fishing and protein supplement in
feeds. Earthworm casting are excellent
soil additives and conditioners for ornamentals and garden crops.
12. Hydroponics or soiless culture of crops, and
organic farming are becoming popular worldwide.
Strict quality control is required, insuring consumers that the products
were not treated with chemical fertilizers and pesticides, and should not
contain a trace of toxic metals, radiation and dangerous contaminants.
13. Don’t throw away Nature’s Gifts, but tap
them instead. Examples: Lantana camara as natural pesticide; oregano as natural
medicine cough and sore throat; chichirica
as drug against cancer; pandan as spice and condiment; eucalyptus as
liniment and cold drops; bunga de China for toothpaste, lagundi for
fever and flu. Many of these plants are
taken for granted and many of them are considered weeds.
How to make
compost with wild sunflower
Wild Sunflower (Tithonia diversifolia) has
enzymes that cuts down composting time to half or third of the usual time. On a
well-drained area, build a compost pile 2m x 4m, with chopped rice straw
(or/with corn stover, mungo or peanut hay, others), 20cm thick, followed by
chopped sunflower plant, animal manure and garden soil half the thickness of
the rice straw.
Repeat making this composite layer four to 6
times until the compost is breast high. Erect 4 vertical “breathing tubes” made
of perforated bamboo. This serves also
as posts.
Water pile regularly, maintain 60 to 70%,
cover with plastic sheet. Harvest compost after 3 to 4 weeks. Test if compost is ripe: pile has shrunk
about half original volume, no foul odor, inside temperature same as outside,
loamy, dark and soft
-------------------------------------------------------------
Life’s more
than the sum of its parts,
Dying as
each creature departs;
Synergy its
secret of unity,
Its harmony and mystery.

Kinds of
Recycling
•
Biological – Trichoderma, a
fungus, to hasten composting
•
Enzymatic – Wild sunflower in
composting, urea in hay
•
Mechanical – Shedding,
decortication, grinding
•
Fermentation –
Silage, retting, biogas digester
•
Burning – Rice hull ash, wood
•
Combination of two or
more of these methods. Ex. Mushroom
production, mulching and composting using rice hay
III.
Recycling in Nature
1. Lightning is Nature’s quickest and most efficient
converter and recycler, instant manufacturer of nitrates, phosphates, sulfates;
it burns anything on its path, recharges ions. Lightning sustains the needs of
the biosphere, it is key to biodiversity.
2. Fire is the Nature’s second tool. While fire is
indeed destructive, in the long run, fields, grasslands and forests are given
new life by it. Fire is a test of survival of the fittest. It is the key to
renewal and continuity of life.
3. Volcanoes erupt to recycle the elements from the
bowels of the earth to replenish the spent landscape, so with submarine
volcanoes that keep the balance of marine ecosystems.
4. The Laws of Nature always prevail with the seasons, weather and
climate. They govern the life cycle and alternation of generations of
organisms; the food chain, food web, and food pyramid. The same applies to long
term phenomena such as Continental Drift and Ice age.
5. Naturally occurring cycles govern the physical and chemical properties
pf the earth’s chemical elements and compounds, principally Carbon, Hydrogen,
Oxygen and Nitrogen (CHON), which are essential to life.
6. Nature recycling of organic materials in through
the action of microorganisms: bacteria, algae, protists (amoeba, diatoms), fungi,
blue green algae. Fibrous materials are broken down by fungi. Other than
roughage and fuel, rice hay is used as substrate for mushroom growing. The spent materials decompose easily into
organic fertilizer.

Recycling of fibrous materials with fungi. Other than roughage and fuel,
rice hay is used as substrate for mushroom growing. The spent materials decomposes easily into
organic fertilizer.
8. Recycling by animals also helps in
controlling the destructive ones such as the mosquito, which is food of fish,
spider and bat.
9. Nature’s nutrient converters. Simple life
forms such as lichens, algae, mosses and ferns silently work on inert
materials, convert them into nutrients
for higher organisms.
10. Nature’s recycling with waterways Mekong
river in Vietnam (below), Pasig River
in the Philippines, Great Britain, Danube and Rhine in Europe, the
Nile, Mississippi,
Amazon, Yangtze, Tigris-Euphrates.
Rivers, lakes, swamps, basins – they provide many basic needs of man.
They are arteries of life, the ecological
bridge between the living and the non-living world. It is said that no civilization exists
without a river.
The 7 Rs in Waste Management
Recycling is integrated in a total management
system.
1. Reduce - plan to limit potential waste
2. Replace with
environment-friendly materials
3. Regulate depends on effective governance
4. Recycle - re-use in original or new form.
5. Replenish. “Pay back” what you get
from nature.
6. Reserve for tomorrow, next
generation, posterity.
7. Revere
- reverence for life, respect creation.
IV.
Non-biodegradable and Toxic Wastes
1. Recyling is not recommended where
pollution is heavy and unabated such as this mudflat. Silt in clean environment is excellent garden
soil.
Mudflat: sediments of debris, silt, garbage and other pollutants
2. Watch out for toxic materials
•
Toxic metals: Cadmium,
Mercury, Lead
•
Hospital and medical
wastes, including radioactive materials
•
Pesticide residues,
especially dioxin
•
Industrial wastes, like
acids, Freon, alkalis
•
Pollution is a serious threat to wildlife, second
to the destruction
of
natural habitats.
3. Oil Spill Recycling? Not with hydrocarbon
compounds; not in the case of oil spill. The
Petron oil spill in Guimaras in 2005 destroyed
thousands of hectares of marine and terrestrial irreversibly upsetting
ecosystems and depriving the residents of their livelihood.
4. Chemical pesticides are concentrated in
food chains by biological magnification

-----------------------------------------------------------------------------------
“How wonderful is creation when we realize in a miniscule
the universality of the simple
linked to the complex,
where every living thing is part
of life’s interrelating;
like a chain, its strength
shared by each link cooperating.” AVR

Recycling:
Key to
Self-reliance,
Homeostasis and Sustainability
1. Recycling helps moderate global warming,
the buildup of heat in the environment from increased human activity in a
postmodern world. Recycling offers
opportunity to everyone
in doing his part in combating global warming,
and the effects of El Niño
2. Recycling corrects the growing imbalance of acidity and alkalinity of the
soil and water (pH value). Too acidic or
alkaline conditions lock up available nutrients useful to life, affect the physiology
of living things. Recycling buffers acid rain which is responsible for the
death of whole ecosystems like forests, coral reefs, and destruction of fields,
pasture, seas, and even valuable pieces of art.
3. Recycling is not ideal where monoculture is
practiced, thus it aims to lead farming back to a system of multiple cropping
and integrated farming. Tri-commodity farms – production of crops, animals and
fish – are best suited to recycling, and guarantee the gains in recycling itself.
4. Self-contained farming is therefore an
important condition for recycling to succeed
- and that recycling in return insures
the success of the other. It is in principal and practice imitating nature.
There is no formula in keeping our environment healthy and balance. This is indeed the answer to spiraling prices
if farm inputs, and the decreasing productivity of farms.
5. E. Schumacher pointed out in his thesis and
book, Small is Beautiful, that being small after all, is the alternative
to corporate failure, the inability of bigness to adjust to change, analogously
like “dinosaur syndrome”, which explains the failure of these primitive
giants to survive abrupt change of their
environment.
Nature’s quickest and most efficient converter
and recycler, instant manufacturer of nitrates,
phosphates, sulfates; burns anything on its
path, recharges ions. Lightning is key to
Biodiversity; it humbles the spirit as well.
Recycling
with Fire.
Fire
is indeed destructive. In the long run, fields, grasslands and forests
give way to new life, spread of pests are controlled It is the key to
renewal and continuity of life.
I am reminded of a friendly encounter with an old man living by a pocket
lake atop Mt Pulog in Benguet in one of
my biology field trips. It is a local
scenario of Henry David Thoreau, the great American philosopher who left town
to live alone by the Walden Pond in a nearby
forest.
Sitting by the lake with Ka Inti I asked him, “What is the best way to
preserve nature?”
“Leave Nature alone.” He quipped.
I expected a different answer because I thought man is the guardian and
custodian of living things - and all creation for that matter.
Ironically man has not succeeded in his obligation
as guardian of the earth. Direct confrontation between man and nature has been
without respite throughout the ages – from the long period of
hunting-gathering, shifting to agriculture, and ultimately leading to today’s
accelerating industrialization.
Modern living or the so called good
life, has farther wedge nature and man apart. Before it was nature that was
the “enemy” of man; now it is man who is nature’s enemy. I wrote this verse to highlight it as a
challenge to all of us.
“The ultimate test of any civilization
is not in its inventions and deeds;
but the endurance of Mother Nature
in keeping up with man’s endless needs.”
AVR
The wisdom of the old man by the lake is deep. Leaving
nature alone is not to be literally
interpreted. Rather it is in knowing and respecting the
laws and rules of Nature, and not in insisting ours. This is where the
conflict lies. Similarly Thoreau saw that the problem lies human
nature - of not responding to his conscience, of not listening to his inner self
- the Little Prince in Antoine de Saint-Exupery’s novel.
“It is only through the heart that one speaks clearly.”
“What is essential is invisible to the eye.”
Nature’s ways are God’s ways, and God’s ways are Nature’s ways. Thus the ways of Nature and Man are one. ~
