英文文献摘要：
The issue of whether profitable preharvest and postharvest marketing strategies exist relative to harvest sales for Kansas crops for the 1985-1998 marketing years is addressed. Practical application of market efficiency concepts is discussed. Nonharvest wheat marketing strategies offered less opportunity relative to harvest sales than for feedgrains and especially soybeans.

讨论了市场效率概念的实际应用。相对于饲料谷物和大豆而言，非收获小麦营销策略提供的机会更少。
