Plant tissue/sap analysis

Plant tissue/sap analysis

Use tissue/sap analysis to help you:

• diagnose or predict nutrient deficiencies or toxicities, and
• monitor the adequacy of your fertiliser program, making adjustmens as necessary.

Tissue/sap testing is only possible once plants are established. Therefore, for an element deficiency to be detected yield loss will already be evident. Plant sap analysis, which indicates the amount of mobile nutrients in the plant’s system, provides a view of nutritional status that differs from that of traditional dry-tissue analysis. In fact, it highlights minor or temporary deficiencies more easily. However, the interpretation data for sap analysis is not always available.
