Horticulture

A type of agriculture that produces perishable items that farmers need to get to the market quickly.

Intensive Farming

Irrigation

Linear Settlement

A settlement pattern in which farms are clustered along a road with fields behind them.

Long Lot

A rural survey method used by the French and in regions of North America previously dominated by the French that involves long rectangular plots of farmland along rivers that have equal access to the water.

Market Gardening

Growing of fruits and vegetables, primarily for the purpose of freezing and canning.

Mediterranean Farming

Agriculture practiced in regions with hot dry summers and mild winters, narrow valleys, and simple vegetation systems.

Metes & Bounds

A rural survey method where land is divided based on the features of the physical landscape and distance and direction.

Mixed Crop/Livestock Farming

An integrated system where crops grown are used to feed the livestock on the same farm.

Monoculture

Specializing in the growing of a single crop.

Neolithic (First) Agricultural Revolution

The origin of farming, marked by the initial domestication of plants and animals.

Organic Food

Food produced without the use of pesticides, synthetic fertilizers, or other unnatural processes

Pastoral Nomadism

Pesticides

A substance used for destroying insects or other organisms that are harmful to cultivated plants or animals

Plantation Farming

Large commercial farming specializing in one crop.

Ranching

Second Agricultural Revolution

Beginning in the 1700s, the advances of the Industrial Revolution were used to increase food supplies and support population growth.

Shifting Cultivation

Farming that involves moving crops from one field to another, clearing the land by burning the vegetation.

Soil Degradation

When soil loses its ability to support plant growth and is more easily eroded by wind or water.

Soil Salinization

When soil in an arid climate has been irrigated for use as farmland and the water evaporates, leaving salt residue behind that eventually causes the land to become infertile.

Subsistence Agriculture

When farmers grow food crops to feed themselves and their families.

Suitcase Farm

A farm on which no one lives and the planting and harvesting is performed by farmers who live nearby or by migrant workers.

Sustainability

Use of the Earth's resources that ensure their availability for future generations to use.

Terrace Farming

When humans build a series of steps into the side of a hill, creating flat surfaces for the purpose of agriculture.

Third Agricultural Revolution

The revolution that began in the 1960s and included the Green Revolution. It was marked by an agribusiness model and involved better and more efficient farming equipment and practices..

Township & Range

A rural survey method where land is divided using latitude and longitude. Land is divided into large squares that can be subsequently divided into smaller squares.

Urban Agriculture

The practice of cultivating, processing, and distributing food in or around towns or cities.

Von Thunen's Land Use Model

An economic model that suggested a pattern for the types of products that farmers would produce at different positions relative to the market where they sold their goods.
