Agriculture can be a great subject for your photography.
Like wild animals, many farm breeds as well as farming methods are disappearing. There is interest in images of these methods/breeds, both as advocacy for maintaining diversity in livestock and to document what could be lost.
To do photography of this nature, I recommend keeping an eye open for events that celebrate old time farming. There you can make the images directly, or make connections that will allow you to photograph the animals later under better circumstances.
Also look for anything that might not be connected with loss of old methods/breeds, but is unusual in a different way. As you can see in my gallery of agricultural images, I have photographed the nostalgic items as well as farming that struck me as unusual and a friend doing genetic research for his graduate study.
