Agriculture Resources and Limitations

2. Natural Systems
Agriculture depends on the interaction of a number of natural systems:
Climate – amount of solar energy (heat) and moisture
Soil – how fertile the soil is depends on how much humus is present. This is affected by moisture.
Topography – level land is generally best for farming
Biology – some organisms are highly beneficial to farming. Example, earthworms, bees. Others are very harmful. Example, weeds, grasshoppers

3. Perfect Farming Conditions
There are very few areas that have the perfect combination for farming:
long growing season
the right amount of moisture
rich soils
level land
right biological conditions

4. Correcting Deficiencies
For thousands of years people have worked to overcome the land they farm.
Some Examples
Irrigation
Pesticides
Fertilizer
Larger Equipment
New seed varieties

5. Different Types of Agriculture
Farming can be described as subsistence or cash cropping
Subsistence farmers – grow crops and raise livestock to meet the immediate needs of their families. They produce many different products, often on small farms
Small Holding- grow crops and raise livestock to meet the families immideite need as well as sell to the local market.
Cash-crop Farmers – the produce is sold in local and world markets. They specialize in producing only a few products on a large farm. They may not use any of the products they grow or raise

6. Different Types of Agriculture
Farming can also be described as either intensive or extensive
Intensive farming – farming a small amount of land with the use of large amounts of labour and capital ($$). Example – fruit and vegetable growing, vineyards, hog factory farms
Extensive farming – large amounts of land with limited amounts of labour and capital. Examples – grain, ranches
