Effects of Salinity Induced by Ammonium Sulfate Fertilizer on Root and Shoot Gr...

Abstract Ammonium sulfate fertilizer is commonly used in highbush blueberry (Vaccinium corymbosum L.) but often causes salt damage, particularly in young plants, when high rates are applied. Three experiments were done to determine the sensitivity of ‘Bluecrop’ blueberry to ammonium sulfate and identify the salinity threshold at which plant growth was affected. In the first experiment, plants were grown in pots...
