- Intervention effect Adding soil N increased leaf total N concentration.
- Intervention effect Adding soil N increased leaf nitrate concentration.
- Intervention effect Reduced light increased leaf nitrate concentration.
- Observation At 600 ft-c, spinach accumulated NO 3 -N and total N at all soil N levels.
- Association Response to increasing soil N was greater at higher light intensities.
- Intervention effect Reducing light from 2400 to 600 ft-c increased tissue K concentration.
- Intervention effect N fertilizer at 200 mg/kg soil increased tissue K concentration.
- Intervention effect Adding N fertilizer to 100 mg/kg soil reduced leaf P.
- Association Leaf P content varied with light intensity.
