Effects of organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries ’Corona’, ’Legacy’, and ’Liberty’
Organic farming does not allow using certain inputs, such as N, which differ in nutrient release rates and dynamics. To evaluate the effect of different organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries (Vaccinium corymbosum L.), a pot experiment was conduc...
