Data Story
About Soil in Hamilton County, New York
Highly Acidic Soils of the Adirondacks
Hamilton County soils are quite acidic with an average pH of 4.51, well below the national median of 6.5. This pH level is also lower than the New York average of 5.11. These conditions are characteristic of the county's heavily forested and wild terrain.
Sandy Texture with Minimal Clay
The soil contains 49.5% sand, 17.4% silt, and only 5.6% clay. This high sand percentage creates a very loose soil structure that allows water to drain quickly. The low clay content means the soil does not compact easily but may require more frequent fertilization.
Unrivaled Organic Richness and Water Capacity
Organic matter is exceptionally high at 67.35%, far exceeding the state average of 17.01%. This massive organic reserve drives an available water capacity of 0.300 in/in, which is nearly double the state average. This soil acts like a sponge, holding vast amounts of water and nutrients in its organic layers.
Variable Drainage in a High-Organic Landscape
While specific drainage and hydrologic classifications are unlisted, the high sand content facilitates rapid drainage. However, the extreme organic matter content likely holds substantial moisture near the surface in many areas. Local growers should focus on managing this high moisture retention for optimal plant health.
High-Altitude Growing in Zone 4b
Hamilton County resides in zone 4b, requiring plants that can handle cold winters and a shorter growing season. The soil is exceptionally suited for native evergreens and cold-hardy berries. Despite the short summer, the high fertility makes for vibrant and lush growth.
