Grade 10: Food from the Land

Types of Agriculture

Mixed Farming

The use of a single farm for multiple purposes, as the growing of cash crops or the raising of livestock.

Mixed Farms..

Advantages Disadvantages

Reduce risk of losing money

Keeps soil from being exhausted

Can plan crops based on variable factors (including demand, climate etc.)

Farmers must divide their attention between multiple endeavours.

Grain Farming

The growing and harvesting of wheat, corn, rice, and other grains.

The Grain Farm Industry

The Grain farming industry includes about 240,000 farms with an annual grain revenue of $70 billion.

Major grain seed production companies are

Monsanto, Syngenta, and DuPont.

Average annual total revenue per grain farm is $300 000.

Top 10% or farms generate 1/3 of total industry revenue.

Dairying

The business of owning and operating a dairy farm.

Crucial Cow Content:

More than 60,000 U.S. dairy farms provide milk, cheese, yogurt and other dairy products to the U.S. and other countries.

About 99% of all U.S. dairy farms are family-owned and operated.

The average herd size on a dairy farm is 135 mature cows.

A cow will produce an average of 6.3 gallons of milk each day.

Ranching

An extensive farm focused on raising a specific kind of livestock; usually large herds of cattle or sheep for meat and wool.

Ranch Information:

People who own or operate a ranch are called stockgrowers or ranchers.

Ranching is also a method used to raise less common livestock such as elk, bison, ostrich and emu

Some ranches cater exclusively to tourists; these are called guest ranches or dude ranches. (not included in Ag. Industry)

Intensive Farming

Also called “intensive agriculture”, is an agricultural production system characterized by the high inputs of capital, fertilizers, labour, or labour-saving technologies such as pesticides.

In Contrast with Extensive Farming, which involves a low input of materials and labour, with the crop yield depending largely on the naturally available soil fertility, water supply or other land qualities.

That’s INTENSE!!

Advantages Disadvantages

Increased yield Leads to cheaper products

because of large quantity Less space for animals

means less energy, and less food required to feed them

Some feel it’s necessary for adequate food production and cost efficiency.

Alters the environment Limits natural habitats

of animals and wildlife Can lead to soil erosion Fertilizers can alter

biology of rivers and lakes

Pesticides can kill useful insects

Not very sustainable

Plantation Farming

A plantation is a large area of land that is usually privately or government owned and employs resident labour to cultivate a single commercial crop.

Plantation agriculture is generally found in tropical and subtropical regions. This type of agriculture has achieved new degrees of efficiency in Central and South America.

Problems with Plantations

- If a natural forest is cleared for a plantation, there is a loss of biodiversity and habitat.

+ BUT creating plantations for wood could eliminate the need to exploit natural forests.

In past times plantations have been associated with slavery.

Rice Farming

Usually exists on a “paddy field”, which is made up of a flooded area of arable land.

Rice can be grown in dry-fields, but from the 20th century, paddy-field agriculture became the dominant form of growing rice.

Rice continued...

Paddy Fields can be built

adjacent to rivers or marshes

constructed on steep hillsides. (high cost)

Require large quantities of water for irrigation.

Rice Farming is very dominant in East, South, and South-East Asia.

Subsistence Farming

Self-sufficient farming in which farmers grow only enough food to feed the family, and to make a living.

Typical subsistence Farms have a range of crops and animals needed by the family.

Modern Subsistence Farming

Largely Subsided in Europe by the start of WWI, and in North America by the 1930’s and 40’s

Small percentage of North Americans would still be subsistence Farmers. (Eg: Hutterites)

Exists today in large parts of Africa, Asia and South America

In areas which are sparsely populated, can be sustainable for a long time.

Nomadic Herding

The act of bringing individual animals together into a group, maintaining the group and moving the group from place to place.

Nomadic Herders

In the drier parts of Asia, especially Southwest Asia, most rural people make a living by raising livestock.

Many are nomads who move with their herds of animals over large territories

constantly seeking good supplies of grass and water

people live simply and carry their tents and belongings with them
