  • Assoc. Prof. and Ext. Specialist
  • Sustainable Cropping Systems
  • Kansas State University

2
A brief history of organic agriculture in the US.
  • The word organic originated in Europe, where it
    was used to designate a type of farming that
    depended on organic matter (not organic
    chemistry).
  • Organic farming has been practiced however for
    about 10,000 years, since humans
    beganintentionally planting crops.

continued.
  • J.I. Rodale admired many historical writers
    including Sir Albert Howard (An Agricultural
    Testament about farming techniques in India),
    and F.H. King (Farmers of Forty Centuries about
    agriculture in China).
  • Lady Eve Balfour, of England, founder of the UK
    Soil Association, first used the term organic
    gardening.

A brief history of organic agriculture in the US.
continued.
  • J.I. Rodale brought the word organic to the U.S.
    when he began publishing Organic Farming and
    Gardening in 1942. He originally financed the
    publication with profits from his plumbing and
    electrical supply business.
  • Later his son Bob Rodale took over the family
    publishing business, and started
    the Rodale Institute to conduct research on
    these methods.

5
A brief history of non-organic agriculture in the
US.
  • Fertilizer products were being tested and used on
    a limited basis in Europe (Rothamsted) and the
    U.S. in the late 1800s.
  • Toxic compounds were used to control insects on
    fruits and vegetables in the late 1800s and
    early 1900s, including arsenic (Paris green).
  • Solutions including copper and sulfur were used
    as fungicides on fruit crops like grapes. Some
    of these are still allowed in organic production.

6
A brief history of non-organic agriculture in the
US. continued
  • Post WWII chemicals used in agriculture included
    insecticides originally developed as nerve toxins
    (organophosphates), herbicides such as 2,4-D, and
    nitrogen fertilizers including anhydrous ammonia
    (used to solidify soil to create air strips).
  • These and other synthetic compounds are not
    allowed in US organic standards.

7
Those flower children
  • The recognition that chemicals such as DDT may
    cause significant harm to non-target organisms
    became public knowledge with publication of
    Silent Spring by Rachel Carson, in 1962.
  • The birth of alternative agriculture began soon
    after, and continued into the 1970s, when it
    began to be called sustainable agriculture.

8
The O word
  • At first, the word organic designated a
    particular type of alternative agriculture, with
    no legal definition.
  • The 1990 US Farm Bill established a National
    Organic Standards Board to develop official US
    standards.
  • Preliminary guidelines released in 1998. A
    record number of comments to USDA required
    re-writing some sections.
  • Final standards released Dec. 2000, and came into
    effect in February, 2001. USDA provides
    accreditation to private and state certification
    organizations.

9
Results since then..
  • Currently 120 organizations are accredited to
    certify, and approx. 10,000 organic farms.
  • Continued expansion of organic markets (20
    annual growth rate for over 10 years). More than
    half of consumers report purchasing organic
    foods.
  • Continued expansion of acres under organic
    production.
  • Trend for more large organic farms, some small
    farms dropping out (of certification programs)

10
Some of the rules.
  • Small farms may use the word organic IF they
    sell less than 5000 of organically produced
    products.
  • If larger than that, must certify, or be subject
    to 10,000 fine.
  • Processors must also certify, and follow strict
    labeling guidelines. (e.g. made with
    organic.etc.).
  • Many certification organizations also attempting
    to meet IFOAM (international) certification
    standards as well.

11
Other new trends
  • More emphasis on locally grown, and knowing the
    person who grows your food.
  • New labeling ideas on a trial basis
    participatory certification and pledges, as
    an alternative to certification. Still use the
    USDA organic guidelines.
  • New local marketing arrangements CSAs
    (community supported agriculture), in addition to
    growth of farmers markets, and sales to local
    restaurants, schools, BBs, etc.

12
And this is important because.?????
  • To become an informed consumer.
  • If you are a gardener who sells occasional
    products (flowers, herbs, vegetables) locally.
  • If you are considering a larger scale production
    operation.

13
For certification, one must
  • Have excellent farm records. Apply for
    certification, participate in annual inspection,
    and meet all requirements.
  • Not use prohibited products/substances.
  • Include set-back zones to avoid potential drift
    problems, including pollen drift.
  • Have a soil improvement plan and practices (cover
    crops, compost, etc.)
  • Livestock must have access to fresh air,
    outdoors, 100 organic feed, and no prohibited
    medications on those sold as organic.

14
Soil improving practices include
  • Crop rotation
  • Cover crops legumes and/or grasses.
  • Soil amendments such as composts and/or manures.
  • Mulches
  • Reduced tillage
  • Soil is the mother of all things
  • Chinese proverb

15
Pest Control Possibilities
  • Systems Approach passive
  • Systems Approach moderate
  • Systems Approach active
  • Note none of these is a business as usual but
    do nothing approach. Also, they all incorporate
    aspects of Integrated Pest Management IPM.

16
Pest Control Possibilities- Weeds
  • Systems Approach passive
  • - high planting density, leafy crops to shade
    weeds, targeted irrigation, rotation
  • Systems Approach moderate
  • -pre-plant tillage, lots of mulch, landscape
    fabric, hand weeding
  • Systems Approach active
  • - corn gluten pre-emergence, flame weeding,
    between row cultivation, soaps as post-emergence,
    livestock grazing

17
Pest Control Possibilities Insects
  • Systems Approach passive
  • - resistant/tolerant crops, attract beneficial
    insects to area
  • Systems Approach moderate
  • - row cover/barrier, clay film barrier,
    diatomaceous earth, vacuum or hand pick, sticky
    traps, pheremones (distruptants and traps).
  • Systems Approach active
  • - botanical pesticides (pyrethrum, sabadilla,
    neem, rotenone), microbial pesticides (Nolo bait
    for grasshoppers, Bt for various larvae.

18
Pest Control Possibilities Diseases
  • Systems Approach passive
  • - grow species that arent affected in our
    climate, live with it, rotation, compost and soil
    improvement for root diseases.
  • Systems Approach moderate
  • - sanitation (residue management, pruning),
    choose specific varieties for disease resistance,
    disease free seeds and plants.
  • Systems Approach active
  • - sulfur, horticultural oils, baking soda
    (sodium bicarbonate), potassium bicarbonate,
    compost tea foliar spray (still experimental, E.
    coli concerns?).

19
Pest Control As Integrated Systems
  • Plan ahead, anticipate, take a design approach to
    your garden.
  • Prevent as many problems as possible, build
    resilience into the system.
  • Monitor plants and pests on a regular basis.
    Problems that are identified early are easier to
    solve.
  • Use least toxic methods first, to preserve the
    beneficial insects and microbes as much as
    possible, and maintain system integrity.

This is not a systems approach.

Systems approach examples bees and chickens
integrated into a fruit orchard.
26
Marketing innovations Community Supported
Agriculture, or CSA, and wild salad mix, i.e.
weeds.
27
Bins can be used for worm composting. Compost can
be either active or static pile. Use screens to
get quality material.
28
Comfrey, a perennial herb, can be composted into
a tea to be used later as fertilizer.
29
Good cover crops for the garden
White clover
Yellow-blossom (biennial) sweet clover
Hairy vetch, Lana vetch, and Purple vetch
Crimson clover

Friends or foes?
31
Friends
Green lacewing
Ichneumon wasp
Syrphid Flies
Two-spotted lady beetle
32
Derived from Kaolin clay, a natural mineral,
forms a barrier film that acts as a broad
spectrum crop protectant. It works to control
insect pests and disease, protect against sunburn
and heat stress. Applied as a water-based slurry
before pests arrive.
Examples of physical pesticides.
D.E. is the fossilized shells of tiny
water-dwelling organisms called diatoms, with
microscopically fine, sharp edges which break the
outer protective layer of the insect and
desiccate them. Applied as a dust or mixed into a
slurry for foliar spraying. Barrier to crawling
pests and soft bodied insects, used in the garden
and as a stored grain additive. Can be used as a
dust on manure for fly control and for intestinal
parasite control.
33
Other barrier methods can protect crops from
insects, and provide early season growth
enhancement, and some frost protection.
34
Winter is for planning. These are thought
intensive methods.
