Other claims from this paper (13)

Intervention effect Leaf area and average ear weight of sweet corn were not affected by poultry litter application frequency or rate.
Intervention effect Increasing poultry litter rate from 10.9 to 21.2 Mg ha-1 increased sweet corn yield by 3128 kg ha-1.
Intervention effect Increasing poultry litter rate to 43.6 Mg ha-1 decreased sweet corn yield.
Intervention effect Sweet corn yields were equal for the fertilizer blend and 10.9 Mg ha-1 poultry litter.
Intervention effect Plant P and K concentrations increased linearly with poultry litter rate.
Observation There were no differences in plant % N or Ca and Mg concentrations.
Intervention effect The highest soil NO3-N concentration at 15-30 cm depth under poultry litter was produced by 43.6 Mg ha-1 PL (15 mg kg-1).
Intervention effect The highest soil NO3-N concentration at 15-30 cm depth under the fertilizer blend was 35 mg kg-1.
Intervention effect Only the high litter rate increased soil NO3-N below 30 cm.
Intervention effect Soil P increased correspondingly as poultry litter rate increased.
Intervention effect Soil K increased linearly from 60 to 200 mg kg-1 as poultry litter rate increased.
Intervention effect Soil pH decreased linearly as poultry litter rate increased.
Intervention effect Soil EC was almost 2 times higher in the 43.6 Mg ha-1 PL plots than at the next highest rate (275 vs. 150 umhos cm-1).
