Interpretive Summary:

Technical Abstract: Rice in California represents a sizeable proportion of the total U.S. harvest. The default growing strategy of yearly monocropping rice without upland rotations or fallows has shown signs of yield gaps in other rice-growing regions in the world, likely due to an accumulation of lignin-derived phenols that limit N fertilizer availability. In this experiment, we investigate the effect of fallow on rice yield. Rice after fallow will be compared to a control of continuous rice to determine differences in yield potential and crop N uptake. Soils will be analyzed for soil phenol content and degree of mineral N binding. The results will assist in creating guidelines for yield prediction and optimal N fertilizer application rates when rice cultivation differs from the default of continuous rice.
