Elstar – Optimization of Nitrogen Fertilization

        
		
            
            

                
This trail, which began in 2025, focuses on whether reducing nitrogen application in Elstar apples can improve coloring without negatively affecting yield and fruit quality. This could potentially lead to cost savings and more sustainable cultivation. The emphasis is on the efficiency of nitrate fertilization rather than ammonium. This trial provides a valuable opportunity to test the effectiveness of nitrogen reduction and to develop a strategy for optimizing nitrogen fertilization in Elstar cultivation. The data will help determine the appropriate nitrogen levels needed to ensure good yield and quality while potentially achieving a significant reduction in nitrogen use.
