  1. Proper balanced nutrition is important in all crops; however, knowing what the right nutrient needed at the right time for the right reasons with the right product can be very different between commodities, orchards, and seasons. There are several different sampling methods that can be utilized to assess the nutrient status of a block and help aid in nutrient management decisions. The main assessment methods are leaf, fruitlet, and soil analysis. There are some other techniques, such as sap analysis, that are being tested and may be more available in the future.
