Other claims from this paper (19)
- Intervention effect Soil Mg fertilization increased available Mg in the 0–20 and 20–40 cm layers.
- Intervention effect After four years, 20–29% of applied Mg remained in those soil layers.
- Intervention effect K fertilization increased available K2O content.
- Intervention effect Some 85–97% of added potassium remained in top soil.
- Intervention effect K fertilization increased apple leaf K content.
- Intervention effect K fertilization increased Mg deficiency symptoms.
- Intervention effect Without Mg, K fertilization reduced tree growth.
- Intervention effect The 300 kg K2O dose adversely affected fruit set relative to 60 kg K2O.
- Intervention effect The 300 kg K2O dose adversely affected fruit storage quality relative to 60 kg K2O.
- Intervention effect Soil Mg fertilization increased apple leaf Mg content.
- Intervention effect Soil Mg fertilization decreased Mg deficiency symptoms.
- Intervention effect Soil Mg counteracted high K2O effects on apple growth.
- Intervention effect Soil Mg did not affect growth with moderate K fertilization.
- Intervention effect Soil Mg had no observed effect on yield.
- Intervention effect Four seasonal 2% epsomite sprays raised leaf Mg less effectively than soil dressing.
- Intervention effect Four seasonal 2% epsomite sprays controlled Mg deficiency symptoms less effectively than soil dressing.
- Intervention effect Foliar sprays increased apple fruit set.
- Intervention effect Foliar sprays increased early yields in the fourth year after planting.
- Intervention effect Soil or foliar Mg increased green skin colour of Bancroft apples, without changing bitter pit incidence.
