Why is much of Nova Scotia unsuitable for agriculture?

Much of Nova Scotia is unsuitable for agriculture primarily due to its underlying geology and rugged terrain. Approximately nine-tenths of the province's landmass is considered unsuitable for farming for the following reasons:

• Acidic Bedrock: A significant portion of the southern peninsula is composed of acidic granite, while large areas of Cape Breton Island consist of acidic and metamorphic rock.1
• Topography: Much of Cape Breton Island is characterized by mountainous, forested terrain that is not conducive to cultivation.1
• Soil Composition: The region is dominated by podzolic soil, which is generally less fertile for traditional farming.1

Agriculture is largely restricted to specific pockets where the soil is underlain by clastic sedimentary rock—such as sandstone—which supports orchards and field crops in areas like the Annapolis Valley, Cobequid Bay, and parts of the Northumberland Strait. Additionally, early settlers utilized dikes to reclaim marshland along the Bay of Fundy for agricultural use.1
