According to the National Organic Standards Board (NOSB) of the United States
the health
Department of Agriculture (USDA), organic agriculture is “an ecological production
and productivity
management system that promotes and enhances biodiversity, biological cycles, and
of interdependent
soil biological activity. It is based on minimal use of off-farm inputs and on
communities of
management practices that restore, maintain, or enhance ecological harmony. The

interdependent communities of soil life, plants, animals, and people.” (NOSB, 2003)
Though the term “organic” is defined by law (see “Legal” section on pages 3
and 4), the terms “natural” and “eco-friendly” are not. Labels that contain those terms may imply some
organic methods were used in the production of the foodstuff but do not guarantee complete adherence to
organic practices as defined by a law. Some products marketed as “natural” may have been produced with
synthetic or manufactured products (those not
considered to be “organic”), such as “natural beef.”
While eco-labels are encouraged for producers
interested in lowering synthetic inputs and farming
with ecological principles in mind (biodiversity, soil
quality, biological pest control), eco-labels are not
regulated as strictly as USDA organic labels.
Products labeled as “organic” meet strict legal
requirements, including certification by a third party.

Organic agriculture is the oldest form of
agriculture on earth. Farming without
the use of petroleum-based chemicals
(fertilizers and pesticides) was the sole
option for farmers until after World War
II. The war brought with it technologies
that were useful to agricultural produc-
tion. For example, ammonium nitrate
used for munitions during World War II
evolved into ammonium nitrate fertilizer;
organophosphate nerve gas production led to the
development of powerful insecticides. These tech-
nical advances since World War II have resulted in
significant economic benefits as well as environ-
mental and social detriments. Organic agriculture
seeks to use those advances that consistently yield
benefits, such as new varieties of crops, precision
agriculture technologies, and more efficient
machinery, while discarding those methods that
have led to negative impacts on society and the
environment, such as pesticide pollution and insect
pest resistance. Organic farming is considered a
systems approach, where interactions between
components (crops, animals, insects, soil) are as
important as the whole farm itself.
Instead of using synthetic fertilizers, organic
farmers use crop rotations, cover crops, and com-
post to maintain or enhance soil fertility. Also,
instead of using synthetic pesticides, organic
farmers employ biological, cultural, and physical
methods to limit pest expansion and increase
populations of beneficial insects. Genetically-
modified organisms (GMOs), such as herbicide-
resistant seeds and plants, as well as product
ingredients, such as GM-lecithin, are disallowed in
organic agriculture because they constitute
synthetic inputs and pose unknown risks (see GMO
discussion opposite).
organic products
The USDA reported on organic produc-
tion statistics in the United States
(USDA-ERS, 2002). This census, conduct-
ed in 2002, identified U.S. farmers who
reported 2.5 million acres of land
dedicated to organic production. This
figure probably under-represents current
production because many organic farm-
ers produce their products organically,
but sell less than $15,000 per year and are exempt
from inspection (see “Organic Certification”), or do
not label their product as organic and, in general,
are direct marketing to a local customer. In 1999,
Iowa farmers reported 150,000 acres of organic
cropland to the Iowa Department of Agriculture and
Land Stewardship (IDALS) survey. This increase in
organic acreage in Iowa represents a doubling from
the previous year and a sixfold increase since 1996.
The U.S. organic industry continues to grow at
a rate of 20 percent annually. Industry estimates
placed it at $10 billion in 2001. The organic industry
is a consumer-driven market. According to industry
surveys, the largest purchasers of organic products
are young people and college-educated consumers.
Today we are faced with the unique opportunity to
take advantage of a growing market demand and
use the technologies developed over the past 50
years. More and more farmers are interested in
the profitability and environmental benefits that
organic systems yield.

In 2001, there were 2.3 million
acres in organic production in
the United States.

Worldwide consumption of organic products has
experienced tremendous growth, often surpassing
the U.S. figures of 20 percent annual gain. Much of
the increase in worldwide consumption has been
fueled by consumers’ demand for GMO-free
products. Because GMOs are disallowed in organic
production and processing, organic products auto-
matically are designated as GMO-free at the
marketplace. European consumers have led the
demand for organic products, particularly in coun-
tries such as the Netherlands, Italy, and Austria.
Two percent of all German farmland, four percent of
Italian farmland, and 10 percent of Austrian farm-
land is managed organically. Prince Charles of
England has developed a model organic farm and
has established a system of government support for
farmers making the transition to organic produc-
tion. Major supermarket chains and restaurants in
Europe and the United States offer a wide variety of
organic products in their aisles and on their menus.
Organic produce has become a more visible menu item at
restaurants around the world.
through conservation of food and nesting sites.
Others import their fertility and pest management
inputs. The philosophy of “input substitution” is
discredited by many longtime advocates of organic
agriculture. A truly sustainable method of organic
farming would seek to eliminate, as much as possi-
ble, reliance on external inputs.

The motivations for organ-
ic production include
concerns about the econo-
my, the environment, and
food safety. Although all
organic farmers avoid
synthetic chemicals in
their operations, they dif-
fer in how they achieve
the ideal system. Organic
farmers span the spec-
trum: some completely
eschew external inputs
and create on-farm sources of compost for fertiliza-
tion and encourage the activity of beneficial insects
The motivations for
When Congress passed the Organic Food
Production Act (OFPA) in 1990, it was heralded by
many as the first U.S. law to regulate a system of
farming. This law can be accessed at the Web site
http://www.ams.usda.gov/nop/. OFPA requires
that anyone selling products as “organic” must
follow a set of prescribed practices that includes
avoiding synthetic chemicals in crop and livestock
production and in the manufacturing of processed
products. Organic certification agencies were
established in the United States to provide the
required third-party certification. Some states,
including Iowa, followed suit and established their
own organic laws. In 1990 Iowa passed Chapter 190,

about the economy,
the environment,

FUNDAMENTALS OF
Organic Agriculture
adopting the definition of
organic as prescribed in
OFPA and establishing
penalties for producers
falsely identifying their
products as organic. Iowa
allows private certification
agencies to operate in
addition to its own certifi-
cation program. This
system is in contrast to
that of California, for
example, which relies on a
private certifier, California
Certified Organic Farmers
(CCOF), and that of Washington, which requires all
farmers to be certified through the state. Inspection
fees average $250 per year per farm to support the
independent inspection structure. Additional fees
are based on sales or individual acreage, depending
upon the agency.
After seven years of revisions, proposed rules
implementing the federal OFPA law were promul-
gated in 1997. However, these rules were revised
and released in 2001. Federal rules require that all
farmers who gross more than $5,000 per year from
organic sales be certified through an agency
accredited with the USDA’s National Organic
Program (NOP). The small farmer exemption allows
small-scale producers to receive the benefits of
premium prices (provided produce is raised organi-
cally) while avoiding certification fees. This
allowance may change in the future, however, and
all farmers are encouraged to join a certifying
association and a network of organic farmers.

Organic Labels
In October 2002, the USDA began enforcing a set of
national standards that food labeled “organic” must
meet, whether it is grown in the United States or
imported from other countries. The use of the seal is
voluntary, so some organic food products may not
carry the new label, but all organic products will
carry notification of third-party certification.
Under the new standards, before a food can be
labeled as organic, a government-approved certifier
must inspect the farm where it is grown to ensure
that it was raised according to USDA organic
standards. In addition, companies that handle or
process food labeled organic must be certified.
The standards permit four different types of
organic labeling. Foods labeled “100 percent
Organic” must contain 100 percent organically
produced ingredients. Products labeled “Organic”
must contain at least 95 percent organic ingredi-
ents. Packages that state, “Made with Organic Ingre-
dients” must contain at least 70 percent organic
ingredients. Packages that claim their products
have some organic ingredients may contain
more than 30 percent of conventionally produced
agricultural ingredients and/or other substances.

Required Certification
Practices for Crops
To sell a product as
“organic” the crop must
have been raised on land
that no synthetic chemical
(including fertilizers, her-
bicides, insecticides, or
fungicides) inputs were
applied for three years
prior to its harvest. In addition, no GMO crops (e.g.,
Roundup-Ready ® soybeans and Bt-corn ® ) are
allowed in organic production.
Split operations, which means conventional and
organic fields are located on the same farm, are
allowed by Iowa law, but they require special care.
For example, a border of 25 feet is recommended
between organic and conventional fields in mixed
operations (see “Organic Soybean Production”
section on page 10).
Only naturally occurring materials are allowed
in production and processing operations, and all
treatments must be noted in farm records.
A crop rotation plan must be in place to protect
against pest problems and to maintain soil health.
Row crops should be raised for no more than four
out of five years, and the same row crop cannot be
grown in consecutive years on the same land.
Legumes (e.g., alfalfa, red clover, berseem clover,
and hairy vetch) alone, or in combination with small
grains (e.g., wheat, oats, and barley), should be
rotated with row crops (corn, soybeans, amaranth,
herbicides, insecticides,
or fungicides) inputs
Added water and salt are not counted as organic
ingredients. The use of the USDA Organic Seal can
only be used on the 95% and 100% organic products.

State of Iowa Organic Certification Program
IDALS began offering a state certification program
in March 2000. Farmers may elect to use the state
program in place of or in conjunction with a private
certification agency. The state program will use
similar rules and fee structures as private
certification agencies operating in Iowa. For more
