What is the recommended timing for using ammonium sulfate as a starter fertilizer on soybeans?


The typical recommendation would be prior to planting. Nevertheless, if weather conditions prevent your from spreading it pre-planting, you may also apply it post-planting. Purdue university work has shown yield responses to 100 pounds per acre of ammonium sulfate applied as late as V4 growth stage.
