How can I fix high draw calls? (Many low poly meshes)

I believe I am getting a very high draw call count because I have several low poly objects in my seen like fences and other small objects. Is there a way to combine all of these into one draw call or a way to reduce that draw call in some way? My current draw call is 105, and I have barely even begun, so it is a bit worrisome. Any tips or solutions would be greatly appreciated !
