# How does our soil moisture balance sheet look? | Integrated Crop Management

> An Iowa State analysis of soil moisture in six northwest Iowa locations found that stored subsoil moisture plus 80% of spring rainfall was below the roughly 20 inches needed for normal corn and soybean yields. The analysis projects moisture balances through early September using average rainfall expectations.
