I pour it on the garden. I helps the microbial activity. I actually sheet compost all my veg scraps, slurry, etc (no meat or fat). That means I pull back the hay mulch and pour on the "stuff" and cover it back up. The worms will compost it in no time and you will increase the nutrition in the soil. Also, interestingly, I have read that over time, vineyards have increasingly more and more of favorable yeasts in the air because of the slurry being used in the vineyards. I think cheesemakers have a similar thing happen.
