Improved Plant Response to Potash Fertilization through Control of Seedling Diseases

IPNI-2012-USA-TN21

Several studies indicate that the commonly used potash fertilizer, muriate of potash, can increase losses of soybean and snap bean to seedling diseases. Supplementary studies suggest that this may be due to a loss in root calcium in young seedlings that occurs with the application of a chloride salt.

Interpretive Summary

2013

Research at The University of Tennessee’s West Tennessee Research and Education Center evaluated the effects of potash application, four seed treatment supplements, and in-furrow applications of liquid calcium nitrate (CAN) fertilizer on snap bean diseases, seedling emergence, plant stand, plant growth, and yield in two experiments in a field naturally infested with several soil-borne plant pathogens.

2012

Several studies have indicated that the commonly used potash fertilizer, muriate of potash, can increase losses of soybean and snap bean to seedling diseases. Supplementary studies suggest that this may be due to a loss in root Ca in very young seedlings that occurs with the application of a chloride (Cl-) salt.
