About Soil in Bronx County, New York
Urban Soils with Unique Acidity
The Bronx features highly acidic soil with an average pH of 4.03, the lowest in this group. This sits far below both the national median of 6.5 and the New York state average of 5.11.
Sandy Mix for Rapid Drainage
The composition is 38.4% sand, 22.2% silt, and only 6.7% clay. This sandy mix leads to fast drainage, which can be a challenge for maintaining consistent moisture in an urban environment.
Surprising Organic Matter in the City
Organic matter measures a surprising 10.62%, significantly higher than the 2.0% national average. However, the available water capacity of 0.120 in/in is quite low compared to the state average of 0.182, meaning the soil dries out quickly.
Water Management in the Urban Landscape
Formal drainage and hydrologic classifications are currently unavailable for this urban landscape. Gardeners should watch for rapid runoff and consider raised beds to better manage water flow and soil health.
Long Growing Seasons in Zone 7b
Located in hardiness zone 7b, the Bronx enjoys a long growing season suitable for heat-loving tomatoes and peppers. Despite a lower soil score of 32.0, the warm climate and high organic matter offer a great start for urban growers.
