How can I make my clay soil more alkaline?

Clay soil will in most cases be alkaline without any amendments. While this might be good enough for some plants to thrive, most others will require you to acidify the soil. For this, organic compounds, sulfur, iron sulfate and ammonia-based fertilizers are an excellent choice.
