Even so, human experience and perception play an invaluable role in characterizing soil properties, especially qualitative properties that may elude sensing/computer-based modeling approaches. The elegant solution to this conundrum relies on the synthesis of computer-aided predictive modeling with human insight and knowledge.As global population surpasses 8 billion, the importance of optimized agronomic production to feed a hungry world has never been more important.展开更多
