Other claims from this paper (14)
- Intervention effect Phosphate fertilizer increased rape biomass significantly.
- Intervention effect Shoot and root total P rose with phosphate fertilizer rate.
- Intervention effect Zinc application did not change shoot and root total P.
- Intervention effect Shoot and root zinc concentrations declined with phosphate fertilizer rate.
- Intervention effect Zinc application increased shoot and root zinc concentrations.
- Intervention effect Soil available zinc increased with zinc application.
- Intervention effect Phosphate fertilizer had no significant effect on soil available zinc.
- Intervention effect Soil Olsen-P increased with phosphate fertilizer.
- Intervention effect Zinc had no significant effect on soil Olsen-P.
- Intervention effect Soil alkaline, acid and neuter phosphatase activities declined with phosphate fertilizer rate.
- Intervention effect Soil alkaline and acid phosphatase activities first rose then fell as zinc increased.
- Intervention effect Soil neuter phosphatase activity was higher with zinc than without zinc.
- Intervention effect Increasing zinc application had no significant effect on neuter phosphatase activity.
- Intervention effect The authors concluded that zinc application improved plant zinc nutrition.
