On this episode, Sarah Marsh Janish welcomes back colleague Dr. Sara Rosenberg, a UCANR Farm Advisor for Mariposa, Merced and Stanislaus counties, to discuss a recent paper she has published. Dr. Rosenberg recently published a paper about part of her dissertation work, the first study to assess soil health and agronomic outcomes in diversified and continuous rice systems in California. This journal article is called "Benefits and tradeoffs of diversifying rice-based cropping systems: Impacts on soil health, productivity, and agroecosystem multifunctionality" and was published in volume 391 of Agriculture, Ecosystems, and Environment. The conversation focused in on one aspect of this fascinating work: how crop rotation in rice systems affects soil microbial communities.

In this episode, Luis Espino and Sarah Marsh Janish give a rundown on stem rot, one of the main diseases of rice in California. One disease that can be found in practically every rice field is stem rot. This fungus causes the tillers to rot at the water level and, when severe, it causes blanking and lodging.
