Title
Available Soil Calcium in Relation to "Damping Off" of Soy Bean Seedlings
W. A. Albrecht; Hans Jenny Botanical Gazette 1931. doi:10.1086/334196
Other claims from this paper (9)
- Association Damping off of soy bean seedlings was closely associated with the nature of soil colloids and the adsorbed calcium ions
- Association Hydrogen ions were not an important factor in determining damping off of soy bean seedlings
- Intervention effect Heavy damping off occurred at low calcium supply but not at high calcium supply, within pH 3.8 to 6.94
- Intervention effect Increasing calcium concentration decreased the number of diseased soy bean seedlings rapidly at pH 7 and at pH 4.4
- Intervention effect At high calcium concentration no damping off occurred between pH 3.8 and 8.0
- Association For chlorides, the importance of cations in checking the disease decreased in the series Ca > Mg > K
- Intervention effect Free, diffusable calcium ions were more effective than adsorbed, exchangeable calcium ions in controlling damping off
- Intervention effect Calcium bound in the mineral anorthite was not able to prevent the disease
- Association Availability of calcium is an important feature in controlling damping off
