Yes. The yearly application of manure, anthill soils, or any other source of stable, organic matter will improve your soil physical characteristics (texture, structure, porosity, etc.) while increasing the water retention capacity. The improvement of fertility although minimal, can be improved eventually through crop rotations, cover cropping, green manuring and similar agronomic practices.
