Oraginc farming in USA

1. U.S.A

2. The climate in USA varies
across different parts of the
country. Generally, the western
and southern parts of US have
warmer weather as compared
to the eastern and northern
parts. The eastern/northern
parts of US experience harsh
winters with heavy snowfall but
the summers are pleasant. The
western/southern part has
extremely hot summers and
comparatively tolerable winters

4. The characteristics of United States rainfall
climatology differ significantly across the
United States and those under United States
sovereignty. Late summer and fall extra tropical
cyclones bring a majority of the precipitation
which falls across western, southern, and
southeast Alaska annually. During the winter,
and spring, Pacific storm systems bring Hawaii
and the western United States most of their
precipitation.

5. Nor'easters moving down the East
coast bring cold season precipitation
to the Carolinas, Mid-Atlantic and
New England states. Lake-effect
snows add to precipitation potential
downwind of the Great Lakes, as
well as Great Salt Lake and the
Finger Lakes during the cold
season. The snow to liquid ratio
across the contiguous United States
averages 13:1, meaning 13 inches
(330 mm) of snow melts down to 1
inch (25 mm) of water.

6. Aerate the soil, aiding water penetration and retention for
young plants;
Help control soil and water losses from erosion;
Help manage residue retention

7. Construct and refine seed beds
prior to planting for added
seedling vigor;
 Incorporate pre- and post-
emergence chemicals for fast
knockdown and effective weed
control;
 Cultivate serious weeds while
preserving seedling growth and
crop root systems;

9. Genetically engineered (GE)
crops (mainly corn, cotton,
and soybeans) were planted
on 169 million acres in 2013,
about half of U.S. land used
for crops. Their adoption has
saved farmers time, reduced
insecticide use, and enabled
the use of less toxic
herbicides. Research and
development of new GE
varieties continues to expand
farmer choices.

10. Organic fertilizers are fertilizers
derived from animal matter,
human excreta or vegetable
matter. (e.g. compost, manure).[1]
In contrast, the majority of
fertilizers are extracted from
minerals (e.g., phosphate rock)
or produced industrially (e.g.,
ammonia). Naturally occurring
organic fertilizers include animal
wastes from meat processing,

12. Made of neem seed oil and sold under
several trade names, this insecticide
should be sprayed on plants at the first
sign of infestation and is a broad-
spectrum product. The seeds come from
the neem tree, which is native to India.
Neem seed oil is a slow-acting insecticide
that may be harmful to house

15. Organic farming methods combine scientific
knowledge of ecology and
modern technology with traditional farming practices
based on naturally occurring biological processes.
Organic farming methods are studied in the field
of agro ecology. While conventional agriculture uses
synthetic pesticides and water-soluble synthetically
purified fertilizers, organic farmers are restricted by
regulations to using natural pesticides and fertilizers.
An example of a natural pesticide is pyrethrin, which
is found naturally in the Chrysanthemum flower.

16.  Crop diversity is a distinctive characteristic of organic
farming. Conventional farming focuses on mass
production of one crop in one location, a practice
called monoculture. The science of agro ecology has
revealed the benefits of polyculture (multiple crops in
the same space), which is often employed in organic
farming. Planting a variety of vegetable crops
supports a wider range of beneficial insects, soil
microorganisms, and other factors that add up to
overall farm health. Crop diversity helps
environments thrive and protects species from going
extinct.

18. Organic weed management promotes
weed suppression, rather than weed
elimination, by enhancing crop
competition and phytotoxic effects on
weeds. Organic farmers integrate
cultural, biological, mechanical, physical
and chemical tactics to manage weeds
without synthetic herbicides.
Mechanical and physical weed control
practices used on organic farms can be
broadly grouped as.

19. Organic farming relies heavily on the natural
breakdown of organic matter, using techniques
like green manure and composting, to replace
nutrients taken from the soil by previous crops.
This biological process, driven
by microorganisms such as mycorrhiza, allows the
natural production of nutrients in the soil
throughout the growing season, and has been
referred to as feeding the soil to feed the
plant. Organic farming uses a variety of methods
to improve soil fertility

or beetle bank
 rotating crops
 companion crops and pest-
repelling plants
 biologic pesticides and
herbicides

22. Organic farms total a respectable number in the
US. There are approximately 12,000 dedicated
farms covering over 1.5million hectares across
all states. Growing slowly in number over the
past decade, growth has slowed exponentially
within the last 6 years. Between 2005 and 2007,
the number of organic farms remained static, at
a number of just below 8,500.

23. This may be because growing crops and food without
synthetic fertilizers or pesticides is more time consuming
and more expensive, which seems ironic – trading
health for convenience, like much of today’s society. The
industry for organic farms however, is now on the rise –
18% growth each year since 2006. This has possibly
been because of people realizing that fertilized food is
actually damaging their bodies. So, whilst the number of
organic farms isn’t growing hugely, the people working
on and companies using them is. This is a positive trend
and one which can only benefit the world as a whole.
Covering 40% of the US in 2007, farmland size (not just
organic) has been on the decline by 1% every year since
then.
