Q: When can my dog return to the lawn after I apply Milorganite?

Q: Is Milorganite effective in clay soil?

Milorganite works well in clay soils, because it contains 85% organic matter by weight. Organic matter improves soil drainage and aeration, moderates soil temperature, and provides pore space in the dense clay, all essential for optimum plant growth.
