Title
The Effect of Calcium on the Growth of Soybeans Supplied with Ammonium Nitrogen
J. J. Siegel; H. W. Hough; L. M. Turk Soil Science Society of America Journal 1952. doi:10.2136/sssaj1952.03615995001600020020x
Other claims from this paper (10)
- Observation Nitrification was inhibited in fumigated soils, resulting in accumulation of ammonium.
- Association Plants receiving ammonium had a higher protein content.
- Association Plants receiving ammonium matured earlier.
- Association Plants receiving ammonium did not produce as much vegetative growth.
- Intervention effect High calcium levels gave the best plant growth where ammonium was the nitrogen source.
- Intervention effect Ammonium-supplied plants had lower total mineral cation uptake than nitrate-supplied plants.
- Observation Soybeans on fumigated soils responded favorably to high calcium levels.
- Observation Soybeans on fumigated soils had a high protein content.
- Association Total mineral cation uptake on fumigated soils was less than on untreated soils.
- Recommendation A high level of calcium is necessary where ammonium is the nitrogen source.
