IPNI Crop Nutrient Deficiency Photo Contest — 2009 Once again, IPNI opens our crop nutrient deficiency photo contest as part of a continuing effort to encourage the art of field observation and increase understanding of the physical appearance of crop nutrient deficiencies and the varying conditions in which they may appear in the field. “This competition continues to appeal to a wide range of practitioners involved in all phases of crop production,” said IPNI President Dr. Terry L. Roberts. “Researchers working under controlled plot conditions are also welcome to submit entries. We encourage crop advisers, farmers, students, and others to photograph and document deficiencies in crops.” Some specific supporting information is required for all entries, including: The entrant’s name, affiliation, and contact information. The crop and growth stage, location, and date of the photo. Supporting and verification information related to plant tissue analysis, soil test, man­agement factors, and additional details that may be related to the deficiency. There are four categories in the competition: Nitrogen (N), Phosphorus (P), Potassium (K), and Other. Entrants are limited to one entry per category (one individual could have an entry in each of four categories). Cash prizes are offered in each of the four categories as follows: First place = US$150.00 Second place = US$75.00 A Grand Prize of US$200.00 will be awarded to the entry with the best combination of photographic quality and supporting evidence across all categories. Photos and supporting information can be submitted until December 15, 2009, and winners will be announced in January of 2010. Winners will be notified and results will be announced at the IPNI website and in this publication. Entries are encouraged from all regions of the world. However, entries can only be submitted electronically as high resolution digital files to: >www.ipni.net/photocontest<.
