About Soil in Grundy County, Missouri
The Gold Standard for Missouri Soil
Grundy County boasts a Soil Score of 78.1, the highest in the group, with a pH of 6.49 that nearly matches the national median. These Entisols are highly prized for their chemical balance and agricultural potential.
Balanced Silty Clay Loam
A composition of 53.4% silt and 25.6% clay creates a robust silty clay loam. This texture offers high nutrient capacity, though the 20.9% sand content ensures the soil remains more breathable than pure clay regions.
High Water Retention in Northern Missouri
Available water capacity is excellent at 0.200 in/in, surpassing the Missouri average of 0.183. While the 2.93% organic matter is lower than the state average, the soil's structure makes every bit of nutrition count for plants.
Reliable Drainage and Slow Infiltration
The soil is well drained but falls into Hydrologic Group C, meaning it has slow infiltration when fully saturated. It manages water effectively for most farming needs, provided that erosion control measures are in place.
Maximizing the Harvest in Zone 6a
The balanced pH and high water capacity in Zone 6a make Grundy County a premier location for a productive garden. Whether you are growing prize-winning tomatoes or staple grains, this soil provides a world-class starting point.
