IPNI Crop Nutrient Deficiency Image Collection

This collection provides a comprehensive assortment of hundreds of classic cases of crop nutrient deficiency documented from research plots and farm fields located around the world. IPNI would like to thank our contributors; many are agricultural researchers, extension staff, crop scouts, and farmers. You’ll find 680 images intuitively grouped according to the three nutrient types required for plant growth (i.e., primary, secondary, and micronutrient). 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.

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.
