ARS soil scientist Laj Ahuja (right) will use information from soil samples to improve a computer model that simulates water moving through the root zone. A soil scientist studies...uh, take a wild guess. He or she seeks to understand how soils form and their basic qualities or properties. For example, soils differ from place to place in part because they contain different ratios of clay, silt and sand. This can affect which plants can grow, how well they can grow, and what farmers may need to do differently to get the best results.
