Data Story
About Soil in Kalamazoo County, Michigan
Typical Michigan Acidity in Kalamazoo
Kalamazoo County's average pH is 5.35, closely tracking the state average of 5.30 but significantly more acidic than the national 6.5 median. This acidity often requires gardeners to use lime when growing pH-sensitive vegetables like asparagus.
Sandy Soils with Low Clay Content
With 57.7% sand and only 8.0% clay, Kalamazoo's soil is very light and workable. This lack of clay makes the soil less likely to form hard clods, but it also means it holds fewer nutrients naturally than heavier soils.
Rich Organic Matter and Moderate Storage
The soil contains 10.23% organic matter, which is excellent for microbial health compared to the 2.0% national average. An available water capacity of 0.165 in/in suggests that while it isn't the most water-retentive, it holds enough to support steady plant growth.
Naturally Draining Sandy Grounds
Though specific drainage class data is absent, the high sand and low clay percentages indicate the soil likely drains quite well. This reduces the risk of root rot for most plants but might require more frequent watering during heat waves.
Abundant Possibilities in Zone 6a
The 6a hardiness zone allows for a long growing season of peppers, tomatoes, and even some varieties of peaches. Kalamazoo’s sandy-rich soil is perfect for building raised beds or starting a productive backyard plot.
