Natural Fertilization in the Backyard
December 06, 2003
Notice the lush, green grass beneath the bird feeder on this lawn in Saginaw, Texas. The photo was taken on October 5, 2003. Analysis of the soil shows a marked lack of nitrogen throughout the lawn. However, the area beneath the bird feeder appears to be getting plenty of nitrogen from bird droppings, which are rich in nitrogen in the form of urates, a waste product from nitrogenous metabolism. The grass shown is Hybrid Bermudagrass GN-1.
