Droppings are disposed by placing a rotating sprinkler within a container over droppings and dissolving the droppings, lifting the open-bottom container from the droppings, and flowing the solution or dispersion outward. A valve actuates the sprinkler once the open-bottom container has been placed over the dropping. A ballast tank fills with water to hold the container down on droppings when disposing of droppings which are resistant to solution or dispersion.
