Soil and tissue analyses are vital for monitoring soil fertility and plant nutrition. Regularly testing soil and tissue nutrients is essential for developing an accurate fertiliser program to achieve peak productivity and ensure efficient and sustainable fertiliser use. It also allows soil fertility issues to be identified early and provides an opportunity to correct them before they begin to affect productivity. The results reported from soil and tissue analyses can often be confusing and include irrelevant information, making their interpretation challenging. The NSW soil and leaf analysis interpretation guidelines for bananas has been developed to assist with the interpretation of soil and tissue tests.
