Everything on earth undergoes a cycle,

Dr Abe V Rotor

    Life cycle of each of these organisms - mosquito, Gambusia fish, Spirulina alga, man, together with tie parasites and symbionts, interact in a complex web - the web of life that constitutes a ecosystem  

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.
 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.

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.   ~  

Jared and the Wild Bean

A modern version of "Jack and the Beanstalk"

A modern day Jared, the boy scholar who popularized the wild bean. Wild Lima Beans or patani (Phaseolus lunatus) was first domesticated by the natives living on the Andes mountain of Peru some 2,000 years BC.
On the the slopes of the Andes mountains, lived a family of indigenous origin. People would describe the region as "far from civilization," as if only those living in town are regarded civilized. 

There was this boy, the only child of that family who wished to live in town.  "No, you are a stranger there." his parents would say.  "Beside it is very expensive to live in town." For indeed up on the slope, everything is free that land, water and air can give. And there is peace and quiet no town can provide.  

Until one day the boy stumbled on a kind of plant that grows up on trees. There it bore pods, plenty of them, green when young and on maturity split open and spill the seeds to the ground. The seeds germinate and produce pods the following season. The family soon learned to cook it as part of their diet, specially when there was little food around.  

Then a year came when the rains did not arrive as people expected.  It was due to the effects of El Niño - a period of drought that starts at the lower part of Peru.  

The boy's parents by experience knew the grave consequence.  Even if you have money you cannot buy anything.  So people looked for alternative food. On hearing this the boy brought the wild beans to town. At first people did not know what it was, until they learned how good it is to eat the beans with their own recipes.   

Secretly the boy brought more of his secret beans. And he made a lot of money. 

After the great drought which lasted for three years, the boy left the slopes to live in town. His parents followed to live with him. 

People wondered where the bean that saved them from hunger came from. The search was far and wide but to no avail.  

Until a boy scholar was able to trace the trail leading to the upper slopes of the Andes. There in a clearing among trees he saw the secret bean, a liana with pods dangling from the trees it made into its own trellis. Jared, the boy scholar took some mature seeds and studied them in school. 

He popularized the bean we know it today as Phaseolus lunatus, or Lima bean, after the capital of Peru. And lunatus for its moon-shape seeds.  Its native name patani survives to this day to places it was introduced which includes the Philippines.   

As to the boy who brought the wild bean downtown, no one had ever heard of him again. But the people in town remembered him whenever the cyclical El Niño struck. 

And Jared, the boy scholar? The one who tamed the wild bean. To them it's a fairy tale. ~ 

NOTE: Today, Lima bean is one of the important legume in the world. It is a good source of dietary fiber, and a virtually fat-free source of high quality protein. It contains both soluble fiber, which helps regulate blood sugar levels and lowers cholesterol, and insoluble fiber, which aids in the prevention of constipation, digestive disorders, irritable bowel syndrome and diverticulitis.

Like other legumes Lima beans contain symbiotic bacteria called Rhizobia within he root nodules of their root system that convert N2 or free Nitrogen into Nitrates (NO3). Nitrates combine with other elements to form compounds needed by plants and other organisms. Wikipedia

Nature in Photography and Poetry in 16 Scenes

It must be Pavlov's conditioned learning,
they come at the time of feeding,
and we, delighted of their friendliness 
believe we are kind and loving.

In each leaf a fountain 
stored from cloud and dew;
I won't thirst on my travel
even days without rain

Beauty begets beauty,
but only for a time;
sooner of later fades, 
with its scent divine. 

There's always a monkey on my back,
asleep or awake,
I lead the evolutionary track     
for all creatures' sake.

What tells you this owl this hour of day?
" I can't join you at night," the owl seems to say,
"with my hunting adventures around the bay,
and you on the computer night and day."

I won't pity you my friend
having reached your end, 
if worth a museum piece,
to disturb man's peace.

You are made of jelly, third state of matter:
colloid pulsing in the computer. 
But I would rather make you a prism 
in search of an unknown realm.

Let him be among the sand pipers and crustaceans;
to grow up unlike us away from sea and sun;
I wonder how we survived not having as much fun,  
in modern caves, concrete jungle, always on the run. 

Whiling away before a wooden frame;
sungka played wild and tame,  
turns friend to fiend; to loot and burn;
all's fair in this ethnic game.  

Tame, though its gene is wild;
sans its own kind in the wild,
human its master and king, 
and every guest its friend - 
but in a little while, one by one
until the species is gone, and lo!
the hero in the last hour, 
would he himself follow.   

Extinct beasts come alive in our midst,
challenging faith and tradition;
seeing is believing yet how nil these are
to the realm of understanding,
a God before and now, near and far,
makes man's awe and thanksgiving.  

Desert ship, the camel tame and dumb,
why of all places you have come? 
is it a new wasteland that you found
from forest and pasture land? 

Nothing beats the native chicken's taste,
and for the convalescing patient;
the karurayan all in immaculate white,
to the herbolario, an angel sent.  

Who can tell a beast from a baby?
all babies though are in a bind; 
and like our own it needs TLC,
orphaned from its own kind. 

A baby elephant with sultry eyes
feeling the touch of a lovely lass;
for a mother's love is also weaned, 
as childhood soon will pass.

Stars of the sea were once 
stars in heaven that fell 
to bring joy in the deep blue 
which was thought as hell.
