Other claims from this paper (10)
- Intervention effect Ammonium sulfate at 4 and 8 g m−2 decreased the seedling establishment rate of uncoated rice seeds.
- Intervention effect Ammonium sulfate even at 8 g m−2 did not inhibit seedling establishment of rice seeds with calcium peroxide coating.
- Intervention effect Ammonium phosphate at 4 g m−2 did not inhibit seedling establishment of both coated and non-coated rice seeds.
- Intervention effect Urea at 4 g m−2 did not inhibit seedling establishment of both coated and non-coated rice seeds.
- Intervention effect Polyolefin-coated urea at 4 g m−2 did not inhibit seedling establishment of both coated and non-coated rice seeds.
- Association Nitrogen application that raises ammonium nitrogen in soil solution at sowing inhibits seedling establishment of non-coated rice seeds.
- Association Nitrogen application that raises ammonium nitrogen in soil solution at sowing does not inhibit seedling establishment of coated rice seeds.
- Observation Ammonium nitrogen in soil solution in the AS plots exceeded 2 mg kg−1, the threshold for seed emergence.
- Observation Soil solution pH was in the appropriate range for rice growth.
- Observation Ammonium nitrogen in soil solution at sowing was below 2 mg kg−1 in all treatments except AS.
