Other claims from this paper (10)
- Intervention effect Mixed nitrogen fertilizer at 30–50% maintained pod number, seed number and grain yield relative to conventional nitrogen.
- Intervention effect Reduced nitrogen with controlled release fertilizer significantly improved apparent nitrogen utilization, peaking at N135R2.
- Observation Nitrogen fertilizer partial productivity peaked at N135R2 after increasing then decreasing with mixing ratio.
- Intervention effect Mixed controlled-release nitrogen did not affect soil urease activity.
- Intervention effect Mixed controlled-release nitrogen significantly increased soil sucrase activity.
- Intervention effect Mixed controlled-release nitrogen increased soil microbial biomass nitrogen and carbon.
- Intervention effect At flowering, 30–50% controlled-release nitrogen significantly increased soil microbial nitrogen and carbon.
- Intervention effect Controlled-release nitrogen had a similar effect on soil inorganic nitrogen content.
- Mechanism The authors concluded mixed controlled-release nitrogen supplied sufficient nitrogen during key rapeseed growth.
- Recommendation The authors recommend 30–50% controlled-release urea with common fertilizer at 25% lower total nitrogen to maintain yield and improve use efficiency.
