Iowa State University maintains a network of observation stations located primarily at the Research and Demonstration Farms, but also at cooperating locations. Data from this network dates back to 1986! Soil temperature influences the availability and uptake of essential nutrients by plant roots. Optimal soil temperature fosters the microbial activity necessary for nutrient mineralization and the release of vital elements. This, in turn, supports healthy nutrient uptake by plants, contributing to their overall vigor and productivity. 4.The 4-inch soil temperature (Figure 1) is below normal across Iowa and much lower than 2021 (up to 20 o F lower). Of interest, the 2022 topsoil soil temperatures are approaching record low levels for the first week of May. As a result, the rate of soil N mineralization is below normal in 2022 (Figure 2).

Figure 1. Iowa’s location in the interior of North America and the lack of mountains to the north and south expose the state to incursions of bitterly cold air masses from the Arctic in the winter and warm, humid air masses from the Gulf of Mexico in the summer.
