Introduction
S. Carolina Cordova currently works as a postdoctoral researcher and field research coordinator at the Kellogg Biological Station and the Great Lakes Bioenergy Research Center, Michigan State University. She works on agricultural sustainability and in particular the biogeochemistry and productivity of annual row crops, managed perennials, and successional systems. Her work focuses on the interaction soil-plant that controls biological nitrogen fixation not only in legumes but also in grasses.

Article
Full-text available
Biological nitrogen (N) fixation is the most relevant process in soybeans (Glycine max L.) to satisfy plant N demand and sustain seed protein formation. Past studies describing N fixation for field-grown soybeans mainly focused on a single point time measurement (mainly toward the end of the season) and on the partial N budget (fixed-N minus seed N...
Article
Full-text available
A continuously growing pressure to increase food, fiber, and fuel production to meet worldwide demand and achieve zero hunger has put severe pressure on soil resources. Abandoned, degraded, and marginal lands with significant agricultural constraints—many still used for agricultural production—result from inappropriately intensive management, insuf...

We used the Agricultural Production Systems sIMulator (APSIM) to predict and explain maize and soybean yields, phenology, and soil water and nitrogen (N) dynamics during the growing season in Iowa, USA. Historical, current and forecasted weather data were used to drive simulations, which were released in public four weeks after planting. In this pa...

Nitrogen fertilizer application to soybean [Glycine max (L.) Merr.] in Iowa, USA, has shown inconsistent results. We performed a study in central Iowa (2015 and 2016) to investigate the effect of N fertilizer rate (0, 45, 90, 135 kg N ha−1) and application timing (planting, flowering, pod setting) on soybean yield, yield components, and to calculat...
Article
The rainfed USA Midwestern region has deep, fertile soils and leads the USA in soybean [Glycine max, (L.) Merr.] production. Biological nitrogen (N) fixation (BNF) contributes a portion of the soybean N requirement, but variability in BNF is poorly understood and estimates of BNF for this region are rare. We established experiments in Iowa, USA to...
Presentation
Full-text available
Most of the previous studies on soybean BNF have been measured at the end of the season, which offers valuable information but not the necessary insight that is needed to understand the dynamics of BNF. Therefore, the aim of our study was to measured soybean BNF dynamics using two methods (i.e., 15N natural abundance, and 15N isotope dilution metho...
Article
Mineral-associated organic matter (MAOM) is a relatively large and stable fraction of soil organic matter (SOM). Plant litters with high rates of mineralization (high quality litters) are hypothesized to promote the accumulation of MAOM with greater efficiency than plant litters with low rates of mineralization (low-quality litters) because litters...
Article
Quantitative measurements of root traits can improve our understanding of how crops respond to soil and weather conditions, but such data are rare. Our objective was to quantify maximum root depth and root front velocity (RFV) for maize (Zea mays) and soybean (Glycine max) crops across a range of growing conditions in the Midwest USA. Two sets of r...

Question
We aim to sequester C in our agroecosystems. However, do we aim to accumulate C and expected to be stable?
