A Sampling of Other Outreach Activities Undertaken by Researchers, related to this Project The Sammis team is currently working with the University of California to evaluate the Remote-Sensing Tool for use by a large almond cooperate farm.

Tree phenology encompasses the complex biological processes of growth and the cycles of flowering and fruit production. Developing a model of tree phenology involves monitoring processes occurring in the soil-plant-atmosphere continuum, such as evapotranspiration and CO2 assimilation.

The first three seasons of field sampling have been completed. Nutrient dynamics in fruiting and non-fruiting leaves suggests that leaves of fruiting spurs may exhibit nutrient deficiencies when non-fruiting leaves on the same tree may have adequate leaf concentrations. (Figure 1).

Results from 2010 leaf analysis for the month of May suggest that leaf samples from fruiting branches have a better relationship with yield than samples from non-fruiting branches, and leaves from the lower canopy have a better relationship with yield than leaves from the top of the branches for the...

This component of the SCRI project allows the systematic study of the interaction between fertility and water management in almonds. Almond research conducted by Bruce Lampinen has demonstrated a substantial influence of water management on tree nitrogen nutrition.
