HI-COTE requires some moisture to initiate the release process by dissolving the nitrogen inside the coating. However, the release rate is primarily controlled by soil temperature, not moisture levels. In drought conditions, the release process may slow if the soil becomes extremely dry. In wet conditions, HI-COTE continues to protect nitrogen effectively, maintaining a consistent release rate. This makes HI-COTE more reliable than conventional fertilizers and inhibitors, which can be adversely affected by excess moisture.
