Tissue testing asks the crop ‘ What’s wrong’ and can be money well spent for growers to confirm a deficiency, or as a check if their crop needs more nutrients. In field crops, plant analysis providing a snapshot in time of nutrient uptake and most useful to indicate when nutrient levels are below critical levels. It can also help with evaluating fertilizer management practices, including potential micronutrient issues.
