- Intervention effect Weed biomass increased with CPM amendment rate in both years.
- Intervention effect Powell amaranth biomass rose 1,775% at the highest CPM rate in 2010.
- Intervention effect Powell amaranth biomass rose 159% at the highest CPM rate in 2011.
- Intervention effect Corn biomass rose 22% with CPM rate in 2010.
- Intervention effect Corn biomass did not increase with CPM rate in 2011.
- Intervention effect Lettuce biomass increased 175% with CPM rate in 2010.
- Intervention effect Lettuce biomass increased 109% with CPM rate in 2011.
- Mechanism Powell amaranth growth under CPM was not attributable to N or K.
- Mechanism Common lambsquarters growth under CPM was not attributable to N or K.
- Mechanism Giant foxtail growth under CPM was not attributable to N or K.
- Mechanism N in CPM was suggested to explain the velvetleaf growth response.
- Recommendation The authors recommend considering nutrient ratios when applying organic amendments.
