Honeoye Soil Series

Honeoye formed in glacial till deposited by the last ice sheet, which retreated from New York roughly 10,000 to 12,000 years ago. The till contains limestone, shale, and sandstone fragments ground up and mixed as glaciers advanced from Canada.

Honeoye is an Alfisol — a soil order defined by an argillic horizon, a clay-enriched subsoil layer that formed as fine particles leached downward over thousands of years. The surface is brown loam. Below it, the subsoil turns yellowish brown as clay and iron accumulated. The deepest layer is calcareous glacial till that still fizzes when acid is applied.

The soil is moderately deep to deep, well drained, and slightly acidic to neutral near the surface, becoming calcareous with depth. Slopes are gently rolling — the classic landscape of the Finger Lakes uplands.

The Honeoye series was identified and named by USDA soil scientists after Honeoye Lake in Ontario County, New York — one of the smaller Finger Lakes in the heart of the region where this soil is most extensive. Naming soil series after nearby geographic features is standard USDA practice.

The Soil Science Society of America recognizes Honeoye as New York's state soil because it captures the two defining forces that shaped the state's landscape: glaciation and limestone bedrock. Together they produced the fertile, well-structured soil that made western New York one of the most productive farming regions in the northeastern United States.

Honeoye was selected over other candidates because it is both widespread and representative. It covers a broad band of the most actively farmed land in the state and reflects the Alfisol soil order dominant across New York's agricultural core.

Digging into Honeoye soil shows a profile shaped by ice and time. The dark brown surface holds organic matter from centuries of plant growth. The argillic horizon — yellowish brown and clay-rich — is where leached materials settled and compacted over thousands of years. At the base, calcareous glacial till crunches with limestone fragments.

Honeoye soil covers the gently rolling uplands of western and central New York, running through the Finger Lakes region and the Genesee Valley. It sits on higher ground between the lakes and river valleys, where glacial till is deep enough for full soil development and drainage is sufficient to prevent waterlogging.

The soil is most extensive in Ontario, Wayne, Livingston, Monroe, Yates, Seneca, Cayuga, and Tompkins counties — the core of the Finger Lakes agricultural belt. It extends east into Cortland and Chenango counties and south into Steuben and Chemung counties.

Corn and hay are the dominant crops on Honeoye soil. The deep, well-drained loam holds moisture long enough for corn to reach maturity in a region where the growing season is shorter than in the Midwest. Alfalfa and mixed hay perform especially well on the neutral-to-slightly-acidic Honeoye profile.

Apples are the signature tree crop. New York is one of the top apple-producing states in the country, and the Finger Lakes counties — sitting on Honeoye and related Alfisols — account for much of that output. The well-drained, calcareous subsoil gives apple roots the depth and drainage they require.

Grapes grow on Honeoye and nearby soils along the slopes above the Finger Lakes, where lake effect moderation extends the growing season. Riesling, Chardonnay, and Concord are the main varieties. Soybeans and winter wheat are also grown in rotation with corn across the Genesee Valley.

Where Honeoye soil is not farmed, the natural vegetation is northern hardwood forest — sugar maple, American beech, yellow birch, and basswood — the same mix that painted the hills of the Finger Lakes orange and yellow before European settlement.
