Forward Pricing Behavior of Corn and Soybean Producers

Soil Organic Nitrogen Enrichment Following Soybean in an Iowa Corn–Soybean Rotation

Understanding soil organic N (ON) pool enrichment may help explain why rates of N fertilization required to attain maximum corn (Zea mays L.) yields are usually lower for corn following soybean [Glycine max (L.) Merr.] than for corn following corn. Our objectives were to quantify the ON pools within a 16-ha Iowa field and to correlate those results with corn yield. Spring and fall measurements ...

Phosphorus and Potassium Placement Methods for Corn and Soybean: an Iowa Perspective

Increasing fertilizer prices and awareness of potential impacts of excessive or badly applied nutrients on water quality has renewed interest in fertilizer management strategies that reduce nutrient inputs or improve efficacy. Fertilizer recommendations for phosphorus (P) and potassium (K) in Iowa and most states of the Corn Belt are based on soil testing and maintenance of desirable soil-test ...

Modeling No-till Adoption by Corn and Soybean Producers: Insights into Sustained Adoption

No-till acreage has increased in recent years, but many farmers alternate no-till with other tillage practices, limiting public and private benefits from sustained no-till adoption. Revealed preference data are used in an ordered logit regression analysis to determine the effect of soil characteristics, climate, regions, farm characteristics, and producer demographics on producers’ choices to u...

The ethical challenges in farming: a report on conversations with Missouri corn and soybean producers.

Interviews with Missouri corn and soybean farmers reveal what farmers consider are important ethical challenges in agriculture. In contrast to the literature, which characterizes ethical challenges in term of philosophical debates about soil conservation, the use of pesticides and genetically modified seeds, and the treatment of animals, for instance, this research finds that farmers perceive e...
