- Intervention effect Newsprint applied with anhydrous ammonia reduced corn biomass production by 75 percent compared with anhydrous ammonia without newsprint.
- Intervention effect Newsprint applied with anhydrous ammonia decreased corn yield by 72 percent compared with anhydrous ammonia without newsprint.
- Intervention effect Newsprint plus poultry litter gave the highest corn biomass production.
- Intervention effect Newsprint plus poultry litter increased corn yield by 37 percent compared with poultry litter without newsprint.
- Mechanism Aluminum concentration in corn tissue and soil solution after newsprint application suggests aluminum toxicity.
- Observation Newsprint induced a nutrient imbalance in corn during the early growing season.
- Intervention effect Biomass produced per day by corn was not affected by N source after 40 to 50 days after emergence.
- Observation As much as 1.5 g kg−1 of organic C from newsprint was mineralized in corn soil when poultry litter, ammonium nitrate or urea was the N source.
- Observation Little organic C from newsprint was decomposed in corn soil when anhydrous ammonia was the N source.
- Observation An average of 4.6 g newsprint kg−1 soil was decomposed after the growing season.
- Recommendation Poultry litter may be the preferred N source for adjusting the C:N ratio of high carbon-based organic waste in corn systems.
- Recommendation Urea and ammonium nitrate would be acceptable N sources in corn production systems that included newsprint application.
