Answered by GPT-5 mini AI
Loess is valuable mainly because it forms deep, mineral-rich, well‑drained yet moisture‑retentive soils that are very easy to till. Being wind‑deposited silt, loess is made of fine, porous particles with lots of mineral nutrients (often calcareous), so it holds water and nutrients well, allows good aeration and root penetration, and produces fertile, productive farmland over large areas (e.g., the American Midwest, the Chinese Loess Plateau).

(One downside: its loose structure also makes it highly prone to erosion if vegetation is removed.)
