| Abstract:
In a field experiment the soil nitrate content to 90 cm depth throughout the growing season in a newly planted 'Elstar'/M9 orchard with "fertigation" or "broadcast fertilizer application plus irrigation" was compared under five different tree strip treatments. The nitrate content was mainly affected by the tree strip treatment. Under the open tree strips fertigation allows sufficient nitrogen nutrition of the trees. However, whether fertigation is an environmentally acceptable way of fertilizer application, as often maintained, cannot clearly be answered with the data of this trial. | |
