Title
Effect of Nitrogen Source on Corn and Bromegrass Production, Soil pH, and Inorganic Soil Nitrogen1
J. F. Power; J. Alessi; G. A. Reichman; et al. Agronomy Journal 1972. doi:10.2134/agronj1972.00021962006400030026x
Other claims from this paper (6)
- Intervention effect Corn production was highest with ammonium sulfate and ammonium nitrate at 110 kg N/ha.
- Observation Leaf tissue at silking of fertilized corn contained over 2.8% total N.
- Intervention effect Bromegrass production was lowest with urea, possibly because of ammonia volatilization.
- Intervention effect Nitrate sources of N greatly enhanced early season growth of bromegrass.
- Observation All fertilizer N applied to bromegrass was immobilized in the ecosystem, with no carryover or leaching of soil nitrate.
- Observation Soil pH changes due to fertilization were not reflected in plant growth.
