Agriculture
Objectives 4.1, 4.2, & 4.4
Agriculture Chapter 9, Outcomes 4.2 and 4.4
What makes a natural material a
potential resource? 4.1.1
Three Conditions must be met
1) Need or Want
2) Technological Development
3) Profitability
System’s Model 4.2.1
A system’s model includes 3 components
1. Inputs (Natural & Human)- Factors put
into a system, that are operated upon by the
system’s processes. EX: fertilizer
2. Processes- Procedures or operations
performed on inputs to produce outputs. Ex:
Ploughing a field for crops
3. Outputs- The products leaving a system,
that result from the systems processes. Ex:
crops growing

Inputs
Natural Inputs in a farming operation
These are provided by the environment.
Examples: Climate, Topography, soil.
Human Inputs in a farming operation
Inputs provided by humans.
Examples: Labour, Fertilizers
Processes
These are the activities used on farms to help grow the crops.
Example:
Situated near Sussex in Smith Creek, Keohanlane Farm, is a dairy farm.
Processes they use include:
Manure management: Store manure in Manure Storage to prevent it from entering the water. They also use it on their crops.
Use strip cropping to prevent soil erosion.
Plant clover in the winter to prevent soil erosion.
Processes
Inputs Processes Outputs
The inputs you have determine the processes you use
both the inputs and processes affect what kind out outputs you get.
So…
Insect

pesticides good harvest
Dry Climate water crops •good harvest
You’ve got insects in your crops…
Use processes like pesticides to get them out!
There… now you’ll have a decent harvest
Input, Process, or Output?
Pick either input, process, or output for the following statements. Vegetable Stand
Output
A piece of cheese Output
Climate Input
Labour Input

Commercial and
Subsistence Farming
Commercial Farming- Any agriculture
system that is geared towards the sale of
its produce.
Subsistence Farming- A form of
agriculture where almost all the produce
goes to feed and support the household
and is not for sale.
Commercial and
Subsistence Farming
Extensive vs Intensive
Extensive Farming: Low Inputs, Labor, and Capital
Low Yields of Crop (Outputs)
Cheap Land
Ex: Cattle Ranching, Grain and Oil Seeds
Intensive farming: Large amounts of labor, inputs and capital
High yields of crop
Ex: fruits. Dairy Farms
Extensive farming vs. Intensive Farming

Shifting Cultivation- Uses a technique called Slash and Burn Cultivation.
An area of land is cleared. Bark is tore from the tree trunks to dry it out.
Later the area is burned. Crops are then planted in the ashes, which serve as a fertilizer.
Once the soil becomes infertile (2-3 years), the area is left for a period of years allowing native trees (Climax Vegetation) and shrubs to re-grow.
Shifting Cultivation
Terms
Agribusiness- Is a large self-sufficient farming operation that produces its own inputs, maintains its own processing facilities, and determines its outputs, which it markets through its own marketing divisions.
Nomadic Herding- The wandering, but controlled movement of livestock, solely dependent on natural forage – is the most extensive type of land use system.
