How to Use Guano on a Lawn

Bat guano's high nitrogen and low phosphorus content makes it an ideal lawn fertilizer. According to the University of Illinois Extension, most healthy lawns require roughly 1 lb. of actual nitrogen per 1,000 square feet per year. Since bat guano is roughly 10 percent nitrogen per pound, that's 10 lbs. of bat guano per 1,000 square feet per year. For the best results, spread this nitrogen feeding evenly over the growing season: once right after green-up, once in the middle of the growing season and once just before the grass goes dormant for the season.
