2015 Annual Interpretive Summary

This on-going research project is designed to develop nutrient deficiency symptoms in the leaves of common horticultural crops by growing plants in a carefully controlled greenhouse environment. During this last year, photographs were taken of nutrient deficient cucumbers, strawberries, and coffee. The first e-book from this research project has been released for reading on a smartphone, reader pad, or computer, illustrating nutrient deficiency symptoms of broccoli. Additional books will be released on other crops as the photographs are compiled and organized. The broccoli book is available for download at the IPNI store or through at
