1. Networks of Precision Farming Trials to Evaluate and Improve Nitrogen Management for CornMost research to improve nitrogen (N) management has been conducted at relatively few locations on experimental farms. The advent of precision farming technologies offers the potential for producers to collect data on their farms. The objective of this paper is to describe how organized networks of producers using precision farming technologies can evaluate and improve N management practices. Pairs of N management practices were evaluated across many fms. Treatments were applied in alternating... B.W. Van de woestyne, A.M. Blackmer, T.M. Blackmer |
2. No-till corn nitrogen recommendation using precision soil management practicesIn long-term no-till fields, South Dakota (SD) farmers reported a reduced fertilizer-nitrogen (N) requirement compared to conventional tillage to obtain optimum corn yield. Reduced fertilizer recommendation may be due to improved soil health resulting from increasing soil organic matter, higher soil microbial activities, and improved water and nutrient use efficiency over the years the no-till system is used. However, the impact of soil health measurements on fertilizer-N requirement has not been... D. Bhattarai, J. Clark, D. Clay |
