Putting all the variables together – management is the best way to influence cover crops effect on yield
You need to add a widget, row, or prebuilt layout before you’ll see anything here. 🙂
How do current recommendations on drainage depth and spacing influence nutrient loss, crop productivity and nutrient utilization?
Can drainage depth and spacing be optimized to minimize the nutrient losses and maximize crop production?
Dr. Laura Christianson, along with her colleagues from the University of Illinois, are exploring various options of drainage water management. “Drain only what is necessary for good trafficability and crop growth — and not a drop more?
This study supports the premise that concentrating N fertilizer below ground near the crop row can increase grain yield and N removal.
In this study, plots that received no N fertilizer still lost a notable amount of nitrate-N through the subsurface drainage system.
It just takes a research meeting in San Antonio to bring the NREC-funded research to the forefront of the agronomy world.
Understanding the influence of tile depth and spacing on nutrient loss – does depth or distance count for something? Research under way by Dr. Rabin Bhattarai from the University of Illinois leads a study investigating how tile depth and spacing variations impact nitrogen (N) and phosphorous (P) losses. The study evaluates current tile drainage design and assesses negative impacts on tile drainage and N and P losses. Click here to download a summary of his current research.
