1. Please state project objectives and what work was done this quarter to address them: To determine how many leaf nutrient sampling per year are required to effectively capture the tree nutritional statusand adjust fertilizer accordingly.2. To establish the relationship of leaf nutrient concentration with yield, fruit drop, and canopy density3. To determine how the leaf nutrient (all 14 nutrient) levels change in the tree throughout the year.4. To evaluate how the leaf age affects the leaf nutrient status.TThe project was initiated in January 2021. In this quarter we were able to tag summer flush on mild and severely HLB-symptomatic trees as well as sample the spring flush for leaf nutrient analysis. We also collected the data on leaf size, weight, chlorophyll index, and starch along with nutrient profile. The preliminary findings were presented at annual meeting of ASHS, Denver, Colardo. 2. Please state what work is anticipated for next quarter: 1. Data analysis and interpretation2. Processing samples for starch3. Collecting samples for nutrient analysis4. Applying fertilizer treatments based on leaf results 3. Please state budget status (underspend or overspend, and why): Currently, the project is in early phase.The budget is being spent as per the plan where major funds have been used for nutrient anlaysis. We have found dedicated personnels to work on this project starting this quarter.
