Other claims from this paper (9)
- Intervention effect Fertilizer plus HA stimulated microbial respiration in lower organic matter soil after seven days.
- Intervention effect These stimulatory effects were absent in higher organic matter soil.
- Intervention effect HA did not significantly affect romaine lettuce emergence rate or percentage.
- Intervention effect HA did not significantly affect romaine lettuce P uptake.
- Intervention effect HA increased lettuce dry mass in one soil.
- Intervention effect HA did not increase tomato macro- or micronutrient uptake in either year.
- Intervention effect HA had no significant effect on tomato dry mass accumulation.
- Intervention effect HA had no significant effect on tomato fruit yield.
- Recommendation Typical commercial HA application is unlikely to significantly improve vegetable nutrient uptake or productivity.
