Other claims from this paper (12)
- Intervention effect Spinach tissue nitrate nitrogen concentration increased with fertilizer nitrogen.
- Intervention effect Both molybdenum rates reduced spinach nitrate concentration at pH 5.0 and 5.5.
- Intervention effect Molybdenum did not affect spinach nitrate concentration at pH 6.5 or 7.0.
- Intervention effect At pH 6.0, 1.2 mg Mo/Kg soil was effective for spinach at nitrogen rates of 50 and 200 mg N/Kg soil.
- Intervention effect At pH 6.0, 1.2 mg Mo/Kg soil had no effect on spinach without applied nitrogen.
- Intervention effect At pH 6.0, 0.3 mg Mo/Kg soil did not affect spinach nitrate at 50 mg N/Kg.
- Intervention effect At pH 6.0, 0.3 mg Mo/Kg soil reduced spinach nitrate without added nitrogen.
- Intervention effect At pH 6.0, 0.3 mg Mo/Kg soil reduced spinach nitrate with 200 mg N/Kg soil.
- Intervention effect At 200 mg N/Kg soil and pH 5.0–6.5, 1.2 mg Mo/Kg soil reduced spinach nitrate more effectively than 0.3 mg Mo/Kg.
- Intervention effect The higher molybdenum rate gave variable nitrate results with no nitrogen or 50 mg N/Kg soil.
- Intervention effect Molybdenum did not affect total nitrogen in spinach.
- Intervention effect Molybdenum did not affect nitrite concentration in spinach.
