Other claims from this paper (12)
- Intervention effect Organic nitrogen or combined mineral or organic nitrogen with humic acid or seaweed increased tree growth traits compared with mineral nitrogen alone.
- Intervention effect The alternative fertilization treatments increased leaf nitrogen, phosphorus, potassium and chlorophyll compared with mineral nitrogen alone.
- Observation Triple-form fertilization gave the maximum growth and leaf nutrient and chlorophyll values.
- Observation Organic and mineral versions of triple and double forms showed no significant differences.
- Intervention effect Double or triple fertilization improved tree nutrient status and C/N ratio.
- Intervention effect Double or triple fertilization increased yield per tree relative to mineral nitrogen alone.
- Intervention effect Double or triple forms increased mandarin fruit weight and pulp percentage relative to mineral nitrogen alone.
- Intervention effect Double or triple forms increased soluble solids, sugar and vitamin C in fruit relative to mineral nitrogen alone.
- Intervention effect Double or triple forms decreased fruit acidity relative to mineral nitrogen alone.
- Observation Triple fertilization forms gave the best fruit quality.
- Recommendation Replacing 25 to 66% of nitrogen fertilization with humic acid or seaweed extract improved tree nutrient status, yield and fruit quality.
- Recommendation The authors say the fertilization approach lets growers produce organic farming products.
