Potential of Elemental Sulfur Fertigation to Reduce High Soil pH for Production...
Machado, RMA; Bryla, DRAbstract Blueberry is adapted to acidic soil conditions but is often planted in high pH soils by adding elemental sulfur (So) prior to planting. Two pot experiments were carried out in a glasshouse to determine the potential of applying Sº by fertigation through a drip irrigation system. In the first experiment, So was applied at four rates of 0, 0.36, 0.72, and 1.44 g per application to 4-L pots filled with o...
Effects of Salinity Induced by Ammonium Sulfate Fertilizer on Root and Shoot Gr...
Machado, Rui; Bryla, DRAbstract Ammonium sulfate fertilizer is commonly used in highbush blueberry (Vaccinium corymbosum L.), but due to a high salt index, it often causes salt damage, particularly in young plants, when too much of the fertilizer is applied. A study was done to determine the sensitivity of blueberry to ammonium sulfate and identify the salinity threshold in which plant growth is affected by the fertilizer. One-year-...
Effects of Method and Level of Nitrogen Fertilizer Application on Soil pH, Elec...
Bryla DR, shirman A; Machado, RuiBlueberries (Vaccinium spp.) require low soil pH and prefer N primarily as ammonium for optimum production. Nitrogen fertilizer methods and rates were evaluated in a new field of `Bluecrop" blueberry (Vaccinium corymbosum L.) to determine their effects on soil pH and availability of ammonium and nitrate in soil solution. Treatments included four application methods (split fertigation, continuous fertigation, an...
