I really like it as a fertilizer - any deer repellant properties are a bonus for me. I work it into my garden soil in the spring & add some during the season when the veggies are heavily feeding. Mom is the opposite - deer repellant first, fertilizer second.
I used Milorganite for conditioning my straw bales when I did a straw bale garden experiment year before last. It worked really well and the plants grew nicely in the composting straw bales. I need two more raised beds .... considering using straw bales to expand the garden rather than building beds, but I have to figure out how to fit them in with my PVC/netting fence configuration.
Worse than the deer are the crows. We have a ‘murder’ of crows (about 11 now) that hang around our place . They use the bird bath and love it, but then they dry out on the board fence around the field (& near my garden) and keep a keen eye on what is growing on the plants. If I don’t have the fence up when veggies first appear, the crows peck or steal stuff & they really destroy semi-ripe/ripe tomatoes. With the fence up, I have to laugh .... they hop around it, looking in, but can’t get to anything. The beds are narrow enough that the crows have no room to fly in & land/takeoff. So far, they don’t sit on the PVC fence. Fun to watch, but they are terrible ‘rascals’.
Yes, it sounds like a great two-fer. Some friends of mine who summer in MN raise incredible veggies w/the straw bale method.
