Other claims from this paper (9)
- Intervention effect Six years of continuous cropping significantly increased lavender essential oil yield by 37.9%.
- Intervention effect Six years of continuous cropping left the relative contents of the listed signature lavender oil constituents stable.
- Observation Soil nutrients under continuous lavender cropping followed a low-high-low pattern.
- Observation Soil organic carbon and total nitrogen peaked after three years of continuous lavender cropping.
- Mechanism Reduced soil disturbance under perennial lavender cultivation was proposed to explain the three-year soil carbon and nitrogen peak.
- Intervention effect Continuous cropping did not significantly change soil bacterial alpha diversity in the 0–20 cm topsoil.
- Association Soil bacterial co-occurrence network complexity decreased with continuous cropping duration across all layers.
- Mechanism Model analyses identified intensified microbial carbon limitation and alleviated nitrogen limitation as drivers of increased lavender oil yield.
- Recommendation The authors recommend three to five years of continuous lavender cropping followed by rotation.
