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. The project was initiated in January 2021. In this quarter we were able to fertilize the trees based on spring flusg nutrient analysis. In addition we have been able to sample spring flush for the second time and are able to make comparisons between randomly picked mature leaves versus spring tagged mature leaf for nutrient analysis. The prelimnary analysis shows that spring flush are deficient in immobile nutrients as compared to random leaves therefore, suggesting that method of sampling can sway the results signifcantly. In this quarter we also sampled summer flusgh for the leaf nutrient analysis for the first time. 2. Please state what work is anticipated for next quarter: 1. Data analysis and interpretation2. Collecting samples for nutrient analysis3. Applying fertilizer treatments based on leaf nutrient analysis results 3. Please state budget status (underspend or overspend, and why): The budget is being spent as per the plan where major funds have been used for nutrient anlaysis.
