Other claims from this paper (8)
- Observation Continuous no-till wheat yield declined from 84 bu/acre in 1987 to 53 bu/acre in 1988.
- Observation Conventional tillage wheat yield remained near 76 bu/acre across 1987 and 1988.
- Intervention effect No-till soybean yield significantly exceeded conventional tillage yield in 1988, 61 versus 46 bu/acre.
- Intervention effect Wheat yield did not respond to potassium rate or application timing.
- Intervention effect Soybean yield did not respond to potassium rate or application timing.
- Association Leaching contributed significantly to soil potassium loss; crop removal explained only part of the missing potassium.
- Observation Wheat and soybeans appear able to obtain substantial potassium from deeper than 12 to 18 inches in the soil profile.
- Recommendation Potassium testing on Coastal Plain soils should include subsoil samples.
