Organic Farming - Certification

Organic certification is a certification process for producers of organic food and other organic agricultural products. In general, any business directly involved in food production can be certified, including seed suppliers, farmers, food processors, retailers and restaurants.


Requirements generally involve a set of production standards for growing, storage, processing, packaging and shipping that include:
- avoidance of most synthetic chemical inputs (e.g. fertilizer, pesticides, antibiotics, food additives, etc), genetically modified organisms, irradiation, and the use of sewage sludge;
- use of farmland that has been free from chemicals for a number of years (often, three or more);
- keeping detailed written production and sales records (audit trail);
- maintaining strict physical separation of organic products from non-certified products;
- undergoing periodic on-site inspections.

















Organic Farming - Organic Movement

In Germany Rudolf Steiner's Spiritual Foundations for the Renewal of Agriculture, published in 1924, led to the popularization of biodynamic agriculture, probably the first comprehensive organic farming system, that was based on Steiner's spiritual and philosophical teachings.

The first use of the term "organic farming" is by Lord Northbourne (aka Walter James, 4th Baron Northbourne). The term derives from his concept of "the farm as organism", which he expounded in his book, Look to the Land (1940), and in which he described a holistic, ecologically balanced approach to farming. Northbourne wrote of "chemical farming versus organic farming". http://www.orgprints.org/10138.

Sir Albert Howard's 1940 book, An Agricultural Testament, was influential in promoting organic techniques, and his 1947 book "The Soil and Health, A Study of Organic Agriculture" adopted Northbourne's terminology and was the first book to include "organic" agriculture or farming in its title.

In 1939, strongly influenced by Sir Howard's work, Lady Eve Balfour launched the Haughley Experiment on farmland in England. It was the first, side-by-side comparison of organic and conventional farming. Four years later, she published The Living Soil, based on the initial findings of the Haughley Experiment. It was widely read, and lead to the formation of a key international organic advocacy group, the Soil Association.

During the 1950s, sustainable agriculture was a research topic of interest. The science tended to concentrate on the new chemical approaches. In the U.S., J.I. Rodale began to popularize the term and methods of organic growing. In addition to agricultural research, Rodale's publications through the Rodale Press helped to promote organic gardening to the general public.

In 1962, Rachel Carson, a prominent scientist and naturalist, published Silent Spring, chronicling the effects of DDT and other pesticides on the environment. A bestseller in many countries, including the US, and widely read around the world, Silent Spring was instrumental in the US government's 1972 banning of DDT. The book and its author are often credited with launching the environmental movement.

In the 1970s, worldwide movements concerned with environmental pollution caused by persistent agrichemical increased attention on organic farming. One goal of the organic movement was to promote consumption of locally grown food, which was promoted through slogans such as "Know Your Farmer, Know Your Food".

In 1972, the International Federation of Organic Agriculture Movements (IFOAM), was founded in Versailles, France. IFOAM was dedicated to the diffusion of information on the principles and practices of organic agriculture across national and linguistic boundaries.

In the 1980s, around the world, various farming and consumer groups began seriously pressuring for government regulation of organic production to ensure standards of production.
This led to various legislation and certification standards being enacted through the 1990s and to date. Currently, most aspects of organic food production are government-regulated in the US and the European Union.

In the 2000s, the worldwide market for organic products (including food, beauty, health, bodycare, and household products, and fabrics) has grown rapidly. More countries are establishing formal, government-regulated certification of organic food: in 2002 in the US, in 2005 in China http://eprints.utas.edu.au/895/ and projected for 2006 in Canada, among others. Monitoring and challenging certification rules and decisions have become a regular, high profile aspect of activists in the organic movement.

Organic Farming - Definition

“Organic farming is a form of agriculture that relies on crop rotation, green manure, compost, biological pest control, and mechanical cultivation to maintain soil productivity and control pests, excluding or strictly limiting the use of synthetic fertilizers and synthetic pesticides, plant growth regulators, livestock feed additives, and genetically modified organisms.”

Directorate General for Agriculture and Rural Development of the European Commission

-

“Organic agriculture is a production system that sustains the health of soils, ecosystems and people.

It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects.

Organic agriculture combines tradition, innovation and science to benefit the shared environment and promote fair relationships and a good quality of life for all involved.”

IFOAM

-

"Organic agriculture is an ecological production management system that promotes and enhances biodiversity, biological cycles and soil biological activity.

It is based on minimal use of off-farm inputs and on management practices that restore, maintain and enhance ecological harmony. "

National Organic Standard Board

-

“Organic farming is the process of producing food naturally.

This method avoids the use of synthetic chemical fertilizers and genetically modified organisms to influence the growth of crops.

The main idea behind organic farming is 'zero impact' on the environment.

The motto of the organic farmer is to protect the earth’s resources and produce safe, healthy food.”

http://www.organic-living.net/

-

“Vegetable and livestock production using natural sources of nutrients and natural methods of crop and weed control, instead of using synthetic or inorganic agrochemicals. Also called low input farming.”

http://www.businessdirectory.com/

-

“Organic farming is a sustainable agricultural with good land-stewardship.

The objective is to produce safe, healthy & affordable food for local community, with minimal-impact on the environment. It should be practiced based on good agricultural practices, and limiting the use o f synthetic agrochemicals, and excluding use of GMOs”

Acacia mangium

Acacia mangium is a species of flowering tree in the Fabaceae family, , that is native to northeastern Queensland in Australia, the Western Province of Papua New Guinea, Papua, and the eastern Maluku Islands.


Common names include Black Wattle, Hickory Wattle, mangge hutan, mangium, Sabah salwood, tongke hutan.


Acacia mangium grows best in warm climates with 1500 to 3000 mm of mean annual rainfall. These soils are acid with medium-to-low fertility and can be poorly drained. Soils with high pH are not tolerated.


Acacia mangium is a fast-growing, medium-sized, evergreen tree with phyllodes that serve as leaves. Trees reach 30 m in height and 60 cm in diameter in their native range. The bark is reddish brown and lightly furrowed









Branchlets, phyllodes and petioles glabrous or slightly scurfy. Phyllodes 5-10 cm broad, 2-4 times as long as broad, dark green, chartaceous when dry. The phyllodes have (3-)4 longitudinal main nerves which join on the dorsal margin at the base of the phyllode, secondary nerves fine and inconspicuous.








The dark brown, crinkled, and coiled ripe pods partially open, and the small (2.5 by 4 mm), black seeds hang by orange, fleshy funicles. The seeds are dispersed when small birds consume the oily funicle or they eventually fall to the ground under the mother trees. Individual trees in an A. mangium plantation produced 1 kg of seed per year





Acacia mangium is planted primarily for site rehabilitation. Its quick growth and dense shade make it an effective tool in reforesting Imperata grass swards and reducing fire risk. Its ability to grow well on infertile soils, especially those low in phosphorus, make it a favorite for rehabilitation of mine spoils and eroded sites. The tree also produces a usable wood. It is hard and has an air-dry specific gravity of 0.69. The sapwood is cream colored; the heartwood is yellow-brown. The wood is suitable for particleboard, plywood, veneer, pulp, fenceposts, firewood, and charcoal. The leaves can be used as livestock fodder

Salute the Trees

Many a tree is found in the wood,
and every tree for its use is good;
some for the strength of the gnarled foot,
some for the sweetness of flowers or fruit;
some for shelter against the storm,
and some to keep the hearth-stone warm;
some for the roof and some for the beam,
and some for a boat to breast the stream; -
In the wealth of the wood since the world begun
the trees have offered their gifts to man,

But the glory of trees is more than their gifts:
"Tis a beautiful wonder of life that lifts,
fom a wrinkled seed in an earth-bound clod,
a column, an arch in the temple of God,
a pillar of power, a dome of delight,
a shrine of song, and a joy of sight !
Their roots are nurses of rivers in birth;
their leaves are alive with the breath of the earth;
they shelter the dwelling of man; and they bend
o'er his grave with the look of a loving friend.

I have camped in the whispering forest of pines,
I have slept in the shadow of olives and vines;
In the knees of an oak, at the foot of a palm
I have found good rest and slumber's balm.
And now, when the morning gilds the boughs
of the vaulted elm at the door of my house,
I open the window and make salute:
"God bless thy branches and feed thy root !
Thou hast lived before, live after me,
Thou ancient, friendly, faithfull tree."

Neptunia plena

Taxonomy

Neptunia plena are a member of the Mimosoideae subfamily of Fabaceae family(1).

When I first encountered this yellow 'Mimosa', I was thrilled to have discovered an exotic species. Obviously, I was wrong assuming that it is a Mimosa. However I was not entirely wrong, at least, as it is indeed a cousin of Mimosa, from Mimoseae tribe(2). Some even name it Mimosa plena, M. punctata, M. adenanthera, or M. lycopodioides as well as many other names (3) .

It is after a long time then I realized that it is actually Neptunia plena 假含羞草 , also known as Aquatic-Dead-and-awake. Thanks to 1001 Garden Plants in Singapore, 2nd Edition. It puzzled me though : who would plant it as a garden plant in the first place. No doubt that the flower is somehow pretty, but not till that extend of bringing it home ! I wouldn’t , for sure.


Distribution

Originated from the tropical America : Texas, Costa Rica, Honduras, Nicaragua, West Indies, French Guiana, Guyana, Suriname, Venezuela, Ecuador, Peru, Paraguay (2). It is now naturalized in tropical Asia (2), becoming a noxious weed, invasive and hard to eradicate.

Botany

Neptunia seems to be water-loving, perennial herbaceous shrub (3). Leaves evenly bipinnate, mildly sensitive to physical touch; glabrous stem; the flower is actinomorphic, numerous stamens, globorous ; pods dehisces when matured (4).
