Spring field operations have already begun across the state, including tillage, anhydrous ammonia applications, and even some planting. Temperatures look up from here, but we cannot rule out periods of cooler conditions between now and May that could impact crop emergence. As of March 18, 2025, the 7-day average 4-inch soil temperature at the Purdue Agronomy Farm (ACRE) was 40.5°F, according to data derived from the Purdue Mesonet Data Hub. Daily soil temperature data can be accessed through the Data Hub, which can be downloaded to compute 7-day running average temperatures. A future update will allow 7-day soil temperatures to be readily accessible. How does the current soil temperature compare to those of previous years? A collaboration between the Midwestern Regional Climate Center (MRCC) and the USDA Midwest Climate Hub has resulted in the Soil Temperature Climatology Tool, which can provide that answer. This tool offers historical statistics for 4-inch[Read More…]
