Other claims from this paper (8)
- Observation Intensively managed orchards generally had high major-element levels in soil attributed to periodic fertilization.
- Observation Leaf major-element content in intensively managed orchards was within the recommended range.
- Intervention effect AM infection in kiwifruit roots decreased in July and August after three June fungicide sprays.
- Intervention effect AM infection in Iyo tangor decreased in July after four fungicide applications in May and June.
- Intervention effect Peach under sod culture retained relatively high AM infection after five fungicide sprays.
- Observation AM spore density seemed low in clean-cultivated orchards frequently sprayed with fungicide.
- Observation AM spore density seemed high under sod culture.
- Mechanism The authors conclude that excessive fertilization, frequent fungicide spraying and clean culture adversely affect AM spores and tree infection in orchards.
