The International Plant Nutrition Institute (IPNI) has released an updated collection containing more than 400 images showing nutrient deficiency symptoms in plants. The photos were collected from research plots, farm fields, plantations, diagnostic labs, and other sources. Some came from an annual contest which IPNI conducts each year, where photos of documented deficiencies are submitted by crop advisers, researchers, extension workers, crop scouts, farmers, students, and others. The images are organized in groups including primary nutrients, secondary nutrients, and micronutrients. The image galleries and search results can be narrowed by available crop-type. Text and diagrammatic descriptions of nutrient deficiency are also available as supporting information. |
