Official State Soil: Holdrege 
September 13th 

This is a photo of the layers that make up a Holdrege soil profile. Holdrege: Grassland Soils. Layer 1: Plowing mixes surface organic matter into the top six inches. Layer 2: Clays washed down by seeping rainwater accumulate in this layer. Layer 3: Lime in this layer makes the soil fizz when you add a little acid. Lime-rich silt was one of the soil's "parent" materials.
