The Accuracy and Informativeness of Agricultural Baselines

May 04, 2021

By Siddhartha Bora

United States Department of Agriculture (USDA) and Food and Agricultural Policy Research Institute (FAPRI), University of Missouri are two main sources of baseline projections for US agricultural sector. Published in the beginning of each year, the baselines provide insight about factors influencing the agricultural sector for the next decade. The projections present a conditional scenario based on certain assumptions about macro-economy, weather, and trade, and serve a basis for comparison of alternative policies. In a new study, we evaluate the accuracy and informativeness of USDA and FAPRI baselines since 1997. We find that the predictive content of most variables in the projections diminish after 4-5 years from the current year, and the USDA and FAPRI models do not outperform one another when entire projection path is considered.

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
