Abstract

The highly specialized maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] production system that dominates midwestern U.S. agriculture has led to widespread on-farm and off-farm degradation of and damage to natural resources. The practice of extending maize–soybean rotations with small grains and forages has great potential to balance production and environmental goals, but adoption of these practices is low. Because little is known about farmers’ perspectives on extended rotations, we conducted social survey research with Iowa farmers to address this knowledge gap. Results show that farmers understand the potential benefits of extended rotations using small grains, but they perceive major barriers to use. The highest-rated barriers were structural, such as lack of markets. Structural barriers cannot be easily addressed by individual farmers, indicating that efforts to address negative impacts of specialized commodity production through extended rotations with small grains will require transformative changes in agri-food policies, programs, and ultimately markets.

美国爱荷华州农民对扩大作物轮作的好处和障碍的看法
高度专门化的玉米(Zea mays L.)和大豆[Glycine max (L.)]稳定。主导美国中西部农业的生产体系导致了广泛的农场内外自然资源退化和破坏。扩大玉米-大豆轮作的做法与小颗粒和饲料具有平衡生产和环境目标的巨大潜力,但这些做法的采用率很低。由于对农民对延长轮作的看法知之甚少,我们对爱荷华州的农民进行了社会调查研究,以解决这一知识差距。结果表明,农民了解使用小粒作物延长轮作的潜在好处,但他们认为使用的主要障碍。评级最高的障碍是结构性的,比如缺乏市场。单个农民无法轻易解决结构性障碍,这表明,通过扩大小谷物轮作来解决专业化商品生产的负面影响,将需要农业食品政策、计划和最终市场的变革。
