Other claims from this paper (13)
- Intervention effect Soybean responses to K placement were generally unaffected by tillage and row width on medium to high K soils.
- Intervention effect K application increased trifoliate leaf K concentrations even on medium to high testing soils.
- Intervention effect Yield most frequently responded positively to direct K fertilization on low K soils.
- Intervention effect Deep banded K increased yield relative to broadcast K only on low K soils with rows near bands.
- Intervention effect On low testing soils, leaf K concentration was over 10% higher for NT soybeans over previous corn rows than between rows.
- Intervention effect On low testing soils, yield was over 10% higher for NT soybeans over previous corn rows than between rows.
- Intervention effect Direct K application increased seed K concentration by up to 3 g kg−1.
- Intervention effect Residual K application increased seed K concentration by up to 3 g kg−1.
- Intervention effect Potassium fertilization increased daidzein, genistein and total isoflavone concentrations in soybean seeds.
- Association Seed isoflavone concentrations were positively correlated with yield.
- Association Seed isoflavone concentrations were positively correlated with seed K concentration.
- Association Seed isoflavone concentrations were positively correlated with oil concentration.
- Recommendation The authors recommend considering preceding corn row effects on horizontal soil K distribution when narrow row NT soybeans follow corn on low to medium K soils.
