A systems-level yield gap assessment of maize-soybean rotation under high- and low-management inputs in the Western US Corn Belt using APSIM
(Elsevier, 2019-08)
Quantifying yield gaps (potential minus actual yield) and identifying management practices to close those gaps is critical for sustaining high-yielding production systems. The objectives of this study were to: 1) calibrate ...

Anaerobically incubated nitrogen improved nitrogen diagnosis in corn
(American Society of Agronomy, 2017-01)
Current N diagnostic methods for corn (Zea mays L.) are often based on the nitrate nitrogen (NO3––N) concentration before planting (pre-plant nitrate test, PPNT) and nitrate nitrogen (NO3––N) concentration at V6 stage ...
