IPNI Crop Nutrient Deficiency Photo Contest—2009
While the classic symptoms of crop nutrient deficiencies are not as common in fields as they were in the past, they do still occur. To encourage field observation and increase understanding of crop nutrient deficiencies and other conditions, the International Plant Nutrition Institute (IPNI) is sponsoring a photo contest during 2009.
“We hope this competition will appeal to practitioners working in actual production fields,” said IPNI President Dr. Terry Roberts. “Researchers working under controlled plot conditions are also welcome to submit entries. We encourage crop advisers, field scouts, 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.
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 posted at the website.
