Agriculture in
Arizona
is a notable sector in the state's economy, contributing more than $23.3 billion in 2018. Arizona's diverse climate allows it to export all sorts of commodities such as nuts, wheat, cotton, eggs, meat, and dairy to the
United States
and 70 other countries. In 2018, the state produced 455.7 million pounds (206.7 kt) of
red meat
and ranked 3rd in producing
vegetables
in the United States, occupying 26 million acres (110,000 square kilometres) of land for farms and ranches combined.
[1]
Due to Arizona's four deserts and very low rainfall, the agricultural sector acquires its water from the state's rivers and streams that include the
Colorado
,
Verde
,
Salt
,
Gila
,
San Pedro
,
Santa Cruz
and
Little Colorado
Rivers.

History
[
edit

History Pre 1850
[
edit
]
Arizona contains the most extended continually farmed land in the United States.
[3]
Research done on
soil
and
pollen
east of the
Grand canyon
in the
Comanche
and
Nankoweap
sites suggest that early Archaic people lived and farmed on these sights for at least a thousands years. Remnants of crops indicate that
corn
and
cotton
may have been grown on the sites.
[4]
The first proven farms in what is now Arizona, were patches of
maize
planted by foragers in the floodplains of the Gila River.
[5]
This area supported many civilizations like the
Hohokam
and
Mogollon
. These cultures planted maize, squash, cotton, and
beans
.
[6]
In the 1600s, the
Spanish
had brought
cattle
to the
New World
that later in the century amounted in the hundreds of thousands, eventually making their way to Arizona over time.
[7]
History since 1850
[
edit
]
A large portion of cattle were moved through Arizona en route to
California
in the 1850s. Permanent herds were not present until the
Civil War
.
[7]
During the Civil War era in Arizona,
Native American
Pima
and
Maricopa
tribes would grow crops such as wheat, corn, beans, melons, and pumpkins by the millions of pounds due to newly acquired technology. When the
Union
and
Confederate
armies made their way to Arizona, relations with the tribes were mostly business related, with the tribes selling their crops (mostly wheat) to the armies. When the Union took control of Arizona,
flour mills
and
granaries
were built and used wheat bought from the tribes. After the war, settlers saw the potential Arizona had to sustain agriculture and began to move in. As for the tribes, though they had profited from the sales of their crops, the new industry had negatively affected them as settlers would move a little too close to their reservations and use their resources.
[8]
Natives had already mastered the art of farming,
[8]
but in the late 19th century, white settlers struggled to adapt their farming practices to the arid climate. In more recent times, the
University of Arizona
Agricultural Experiment Station provided settlers with ways to adapt and increase crop yield. This helped turn the University of Arizona into the center of Agriculture for the American Southwest.
[3]
Irrigation
and water rights shaped the development of the industry in the 20th century. Notably,
Arizona v. California
(1962) resulted in the US Supreme Court ruling that Arizonian farmers could draw water from Colorado River tributaries without federal regulation. This caused a boom in agricultural output. However, concerns about sustainability remain.
[9]
Notable crops
[
edit
]
Leafy greens
[
edit
]
Contributing $2 billion to Arizona's economy in 2015, the state ranks second in the production of
leafy greens
such as
lettuce
and
spinach
. In 2007, producers created the Arizona Leafy greens program assuring that greens produced with the program are produced with food safety in mind by using strict protocols. The program has since set a higher standard and good model for food safety that allowed other commodities and states to follow.
Yuma
is known as the "Winter Lettuce Capital of the World" due to the county's very high production of lettuce during the winter season having 90% sunshine year-round, rich soil, and the Colorado river. Leafy greens are also produced in Maricopa county.
[1]
Grapes
[
edit
]
With Arizona not receiving much rainfall,
grapes
can still be grown in 1,250 acres (510 hectares) as they don't require much water. Most if not all grapes are then used to produce
wine
, as 300,000 US gallons (1,100,000 litres; 250,000 imperial gallons) of it was produced in 2015, with the market valued at $25 million. Grape
vineyards
can be found in
Cochise
,
Santa Cruz
, and
Yavapai
counties.
[1]
Pecans
[
edit
]
Pecans
are a
staple
in Arizona's agricultural industry, having the biggest
pecan grove
in the globe spanning some 8,000 acres (3,200 hectares).
[1]
Pecans are grown on 22,000 acres (8,900 hectares), with 30,000 more acres (12,000 hectares) of them on the way in the next few years.
[1]
In 2016, 22 million pounds (10.0 kilotonnes) of pecans were produced and made $55 million in revenue.
[1]
Pecan trees can be found in Cochise, Gila, Graham, Greenlee, Maricopa, Mohave, Pima, Pinal, and Yavapai counties.
[1]
Cotton
[
edit
]
A great history of
cotton
exists in Arizona, but its greatest development came later on with
Egyptian cotton
(
Gossypium barbadense
), later called Pima cotton, that is stronger than
short-staple cotton
and still as soft. Every year, the cotton industry earns the state $400-500 million and creates 3,000 new jobs.
[
dubious
–

]
Cotton is such a valuable and diverse plant that even its
seed
, stalk, and lint have uses, earning its place as one of Arizona's "5 C's." Cotton is grown in Cochise, Graham, Greenlee, La Paz, Maricopa, Mohave, Pima, Pinal and Yuma counties.
[1]
Wheat
[
edit
]
For more than 100 years,
wheat
has been a large commodity in Arizona. Grown by the Pima and Maricopa tribes during the Civil war, Native Americans would sell wheat to soldiers who later constructed granaries for it, resulting in its bigger industry today. Wheat produces 100 US bushels per acre (8,700 litres per hectare) and earns the state $200-350 million annually. Wheat is grown in Cochise, Graham, La Paz, Maricopa, Pima, Pinal and Yuma counties.
[1]
[8]
Dates
[
edit
]
Arizona ranks second in the production of
dates
(
Phoenix dactylifera
), and the biggest date plantation in the globe is found in the state. Dates can be harvested in the months of September and October. Dates have a unique history in the state, as they are originally from the Middle East and North Africa, but were brought to North America by Spanish conquistadors and eventually made their way to Arizona.
[10]
[1]
Other commodities
[
edit
]
Eggs
[
edit
]
Arizona's commercial
egg
industry began in Nell Hickman's home not too long ago in 1944, and has since grown to sell 360 million dozens of eggs in the state annually. Egg facilities today use automated machinery to reduce human interaction and hasten the process of packaging, allowing eggs to go from farm to plate in less than a day.
[1]
Dairy
[
edit
]
In 1922,
Shamrock Farms
was opened, making agriculture a notable sector in the states economy. In 1960, the
United Dairymen of Arizona
was founded to provide a sustainable supply of
dairy
products and fresh
milk
for consumers at the best quality. With the help of modern technology, the UDA's
Tempe
facility runs 24/7, allowing 1 million US gallons (3.8 megalitres) of milk to be processed daily. The state has more than 205,000 cows for dairy, produces 4.2 billion pounds (1.9 megatonnes) of milk annually, and takes 2 days to get milk from the farm to a store. The dairy industry operates in Cochise, Gila, Greenlee, La Paz, Maricopa, Navajo, Pinal, Yavapai and Yuma counties.
[1]
Livestock
[
edit
]
Out of 20,005
ranches
and farms in Arizona, cattle is raised on more than 30% of them. In 2015, Arizona's cattle industry allowed ranchers to produce 1.4 billion beef meals and feed 8 million people, and in 2018, the state was able to produce 455.7 million pounds (206.7 kt) of red meat. The economic impact contributed by the sale of beef is worth around $521 million. Arizona's cattle industry operates year round and can be found in every county all over the state.
[1]
Past and Modern practices
[
edit
]
Pre-colonization Agricultural Practices
[
edit
]
Prehistoric
indigenous cultures
planted crops along the floodplains of the Gila River.
[5]
Among these, the Hohokam settlement of
Snaketown
was the first to use canals to irrigate. These canals diverted water from the Gila River a few miles upstream from Snaketown and brought it to the crops outside the settlement. The advent of pottery enabled these cultures to store food for longer periods of time, increasing agricultural efficiency.
[6]
Modern Agricultural Practices
[
edit
]
Arizona is blessed with many rivers, streams, and tributaries so irrigation is still a major practice today. Water rights are divided among different municipalities. Great care is taken to ensure that water is not wasted. This coordination is facilitated by the
Agribusiness and Water Council of Arizona
.
[1]
The majority of large scale growers today practice
conservation agriculture
, which includes
reduced tillage
,
intensive tillage
,
cover cropping
,
manure
application, and commercial
fertilizer
application.
[11]
Resource use
[
edit
]
Because of its large deserts, population growth, and ongoing drought, concerns over energy and water use in Arizona increase every year. In response, heads from all over the private sector and government have taken action to sustain the state's water supply. This isn't the first time Arizona has had issues with water, as seen in the
Arizona v. California
Supreme Court case in 1952 that disputed water use from the
Colorado River
's lower basin. The use of energy and water go hand in hand as a large portion of the state's available energy is used for irrigation with Arizona being a desert state.
[1]
[2]
[9]
Water use
[
edit
]
Due to the
arid climate
, 70% of Arizona's water consumption is used for agriculture with some crops in using about 4.9 million acre-feet (6.0
×
10
9
cubic metres), but with the help of today's technology, farmers are able to use only what they need and water that isn't used goes back into rivers or storage. As an example on just how much water is needed, an average head of
cabbage
uses around 64 to 107 US gallons (240 to 410 L; 53 to 89 imp gal).

Energy use
[
edit
]
The energy required to grow crops in Arizona can reach a maximum range of about 36 trillion British thermal units (11 million megawatt-hours).
[2]
To put into perspective, this amount of energy is the same as 290 million US gallons (1.1 gigalitres) of
gasoline
.
[2]
Taking cabbage as an example again, to grow 1 acre (0.40 hectares) of it requires about 79 US gallons (300 litres; 66 imperial gallons) of diesel fuel to operate farm machinery.
