There are two ways to access the information about nutrient factors that affect your crop, which are accessible by following the drop-down links on the left hand menu:

• List format - list of information sheets organized by deficiencies and toxicities. (This is a good option if you are already fairly sure what your problem is - i.e. nitrogen deficiency, aluminum toxicity, etc.)
• Identification key - will guide you through the process of identifying which nutrient is the reason for your production problems. (This is a good option if you are not yet sure the cause of your crop problems.)

For additional information on methods of identification and more technical details on the nutrients, follow the links below:
