Other claims from this paper (11)
- Method / resource Second-order polynomial models fitted the nutrient accumulation of hydroponic blueberry with adjusted R2 of at least 0.94, revealing dynamic uptake patterns.
- Observation In the first phase (60-90 days after transplanting) iron uptake was maximal (0.13 mg per plant per day).
- Observation In the first phase (60-90 days after transplanting) uptake of phosphorus, calcium and magnesium was maximal.
- Observation In the first phase (60-90 days after transplanting) sulfur uptake was maximal.
- Observation In the first phase (60-90 days after transplanting) uptake of the immobile micronutrients zinc and manganese was maximal.
- Observation Net nitrogen absorption declined by 51.45 mg per plant per day between 90 and 120 days after transplanting.
- Mechanism The nitrogen decline indicates significant internal remobilization towards reproductive organs.
- Observation The final stage (150-200 days after transplanting) was dominated by intensive potassium uptake (54.76 mg per plant per day) for fruit filling.
- Observation Calcium and micronutrient (boron, copper) absorption plateaued or declined in the final stage.
- Mechanism The plateau or decline is attributed to limited xylem transport under high temperatures (above 39 C).
- Recommendation The results provide a quantitative foundation for fertilization strategies aligned with phenological development to enhance nutrient use efficiency and fruit quality under tropical conditions.
