Y. Chen; R. Samson Transactions of the ASAE 2002. doi:10.13031/2013.8826
Other claims from this paper (5)
- Observation Residual nitrate nitrogen trends varied among experiments and were inconclusive.
- Intervention effect Manured plots had twofold higher soil P concentrations than inorganic fertilizer plots.
- Recommendation Preplant manure or sidedress manure without starter fertilizer could increase weed pressure in no-tillage corn.
- Intervention effect Liquid manure as fertilizer raised or maintained corn grain yield by 6% when weeds were not a problem.
- Recommendation Authors recommend combined manure and inorganic fertilizer treatments for corn based on runoff risk and yield potential.
