e1“When the soil was adequate limed, maximum yields were obtained when the soil contained 45 pounds per acre of P 2 O 5 extractable with 0.002 N H 2 SO 4 buffered at pH 3 with (NH 4 ) 2 SO 4 or 110 pounds per acre of P 2 O 5 extractable with 0.03 N NH 4 F in 0.1 N HCl”

Other claims from this paper (15)
- Intervention effect No yield response of peanut to nitrogen was obtained.
- Intervention effect Potash above 15 pounds K2O per acre as potassium chloride gave a negative response every year.
- Observation Ninety pounds of exchangeable potassium per acre was adequate for maximum peanut yields.
- Association The lack of peanut response to potassium may be associated with fertilizer potassium placed in the peanut row or with increasing phosphorus rates.
- Recommendation Excess potassium equal to that removed by peanuts should probably be applied to the other crops in the rotation.
- Intervention effect A significant peanut yield response to phosphorus was obtained every year.
- Observation On adequately limed soil, maximum peanut yields were obtained at 45 pounds per acre of soil P2O5 extractable with the 0.002 N H2SO4 method.
- Intervention effect Calcium gave significant peanut yield responses in three out of four years.
- Intervention effect Three tons per acre of dolomitic lime gave better peanut results than one ton per acre.
- Intervention effect One ton per acre of lime raised soil pH from 5.3 to 5.6.
- Intervention effect One ton per acre of lime raised exchangeable calcium from 300 to 500 pounds per acre.
- Observation With 3 tons per acre of lime, soil pH was 6.2.
- Observation With 3 tons per acre of lime, exchangeable calcium was 850 pounds per acre.
- Association Phosphorus interacted with lime in peanut yield response.
- Intervention effect Less fertilizer phosphorus was needed for maximum peanut yields on limed than on unlimed soil.
