Potassium-deficient rice Potassium-deficient rice will have yellow or brown areas on leaf tips and edges.

Soil fertility is one of several factors, including light, moisture, weeds, insects, and diseases, that affect crop yield. An important part of crop farming is being able to identify and prevent plant nutrient deficiencies and toxicities. This publication provides background information on the nature and development of crop nutrient disorders under the growing conditions commonly encountered in Missouri. The publication discusses plant tissue testing as the most accurate diagnostic tool for nutrient deficiencies. Methods for diagnosing nitrogen deficiency by measuring plant color, either in the field or remotely, are discussed. Crop Nutrient Deficiencies and Toxicities is part of a series of Integrated Pest Management manuals prepared by the MU Plant Protection Programs.
