Soils & Climate

The soils of Cortland County vary considerably in physical properties and in suitability for crops and other uses. Soil associations dominated by high lime areas occur in the northwestern and northeastern parts of the county along county lines. Medium lime soils occupy the transitional areas between the high and low lime soils. The central, north-central and southern parts of the county include areas of low lime soils with a strong fragipan.

The glaciated landscape in Cortland County accounts for the complexities of our soils. Ten soil associations are found in the county. The most productive soils are found in the northern plateau areas. In the southern half of the county, the hilly topography and low lime soils limit crop production

The general topography is hilly. The county is characterized by narrow deep valleys, intervening plateaus and high hills (highest county elevation - 2100 feet).

Variations in topography have significant affects on climate. The influence of Cayuga Lake on climate appears to be confined to areas adjacent to the shore. In most years, the freeze free season ranges between May 5 - 20 through September 25 - October 15. Annual precipitation totals between 30 and 40 inches.

Growing Degree Days (GDD) are a measure of heat accumulation used by horticulturalists to predict the date that a flower will bloom or a crop reach maturity. Statistics for the Northeast are provided on this Cornell Atmospheric Sciences & Turf Team website.

The Cornell Garden Based Learning website includes a section on Weather & Climate that includes information on Growing Degree Days, US plant hardiness zones, average frost dates, and microclimates.
