Other claims from this paper (15)
- Observation Soybean nitrogen fixation percentage was higher in 2003 than 2002.
- Intervention effect TS produced a significantly higher soybean nitrogen fixation percentage than the other three tillage treatments.
- Intervention effect TS increased nitrogen fixing enzyme activity.
- Intervention effect TS improved soybean BNF ability.
- Intervention effect TS resulted in higher soybean yield.
- Association Fixed soybean nitrogen was negatively related to soil nitrate nitrogen.
- Association BNF activity was reduced above a soil nitrate concentration of 40 kgN/hm~2.
- Observation Without BNF, soil supplied all soybean nitrogen requirements.
- Observation Absence of BNF led to soil nitrogen depletion and scarcity.
- Association Soybean aboveground biomass increased with nitrogen fixation percentage, especially under TS.
- Association Fixed soybean nitrogen was positively related to aboveground biomass.
- Intervention effect TS had the highest 2002 BNF contribution to total nitrogen input.
- Observation In 2003, soybean nitrogen fixation percentage ranged from 43.8% to 62.4%.
- Observation In 2003, soybean fixed nitrogen ranged from 10.7 to 17.6 kgN/hm~2.
- Observation In 2003, fixation contributed 40% to 63% of total nitrogen.
