what rights do land owners have as to the use of their property

This question is too vague to answer.  The simple answer is a land owner can do anything with his/her land that is not illegal or violate the rights of others.  I suggest you contact a local real estate attorney to discuss your situation to determine if your actions are legal, or if you are in violation of other people's rights, ie noise pollution, etc. This is not intended to be legal advice, and is general in its nature.
