How Manure Impacts Soil Aggregation

Researchers compare differences between soils fertilized with three types of manure versus commercial products and note four benefits, including an increase in water-stable large macro-aggregates that hold P differently.

Alfalfa Production

Determining When It's Time to Replace Thinning Alfalfa Stands

Are you seeing thinning stands and more weeds in your alfalfa than you'd like? If so, take time out this summer to determine whether you may need to replant the field or rotate out of alfalfa to provide a nitrogen boost for the next crop. Here's a quick guide to assess potential production based on number of shoots per plant.

Detection and Characterization of the Causal Agent for Bacterial Leaf Streak in Corn

When a new crop disease strikes, researchers dig in to identify its characteristics. Noting how it's similar to and different from other diseases are part of defining it so plant pathologists can better confirm its presence in the field, monitor its spread, and develop appropriate management practices. Here's the story of how plant pathologists identified bacterial leaf streak.
