How long does new topsoil take to settle?

Good afternoon, I'm curious about the process of new topsoil settling. Could you elaborate on the typical timeframe it takes for newly applied topsoil to become stabilized and ready for use? Are there any factors that might accelerate or delay this process, such as weather conditions or the quality of the soil itself? I'm particularly interested in understanding the importance of this settling period and how it impacts the overall health and productivity of the land. Thank you for your insights.
