Using clay balls to plant on the desert

I have 2.25 acres of land in north central Nevada and would like to begin developing the soil.  Ideally, I would also like to make the land a little more pretty by planting wild flowers.  I have lists of plants that will grow in the area but I am trying to find ways to broadcast them and keep a significant percentage of the seeds from being eaten by insects and rodents.  Any suggestions?  I have read of people putting seeds in clay balls along with other substances that most insects and animals think is obnoxious - one example being diatomaceous earth.  What I have read is that seeds have a better chance of sprouting if they are planted in late fall, which is when the rainy season (if you can call it that) begins.  Any suggestions on this?

I admire your tenacity.

You are right about planting seeds in the fall.  That is natures way of stratification.

And yes, seeds need rain (aka water) to germinated.

Put the seed balls out just before it rains and then wait to see what happens.  Some results will not be seen until Spring.

Here are a couple of threads about how to make seed balls:
