Results of the 2006 Crop Nutrient Deficiency Photo Contest  Winners in the four categories of the 2006 PPI crop nutrient deficiency photo contest have been determined. In this first year of the contest, awards were given for first and second place photos in four categories: Nitrogen, Phosphorus, Potassium, and Other (secondary nutrients, soil pH, etc.). Read Full Story Dr. Cliff Snyder is the new Nitrogen Program Director for IPNI IPNI has named Dr. Cliff Snyder to the new responsibility of Nitrogen Program Director. “He will coordinate our efforts dealing with the environmental issues associated with nitrogen fertilizer use in agriculture, including North America and internationally,” said IPNI President Dr. Terry L.

 Toolbox Software downloads & self guided tutorials Toolbox resources Site-Specific Management Guidelines The objective of the Site-Specific Management Guidelines series is to provide a mechanism to assemble expert knowledge in a timely fashion on site-specific management in a form useful to farmers and their advisers. Each Guideline addresses a specific issue related to site-specific soil and crop management. Currently there are 45 titles in the series, which can be accessed from the list below. List of SSMG topics The Fertility of North American Soils This is a report of the phosphorus (P) and potassium (K) fertility of the soils of North America. The data used in this report were provided by 70 major North American public and private soil testing laboratories that analyzed 3.4 million soil samples submitted to them by farmers and their advisers for the purpose of determining the amount of plant nutrients to apply prior to the 2005 growing season. As such, this summary is probably the most comprehensive evaluation of the status of soil fertility in North America ever conducted.

For example, what about corn after corn instead of a corn/soybean rotation? What are the options to improve N use efficiency? How can growers estimate nutrient use efficiency on the farm? IPNI North America staff have prepared some timely articles to help address these issues. Click here for the articles Crop Nutrition PowerPoint Series The Crop Nutrition Series of PowerPoint presentations features crop nutrition and management information prepared by IPNI North American Program scientific staff. Each presentation includes approximately 40 slides each, with extensive speaker notes and reference information. Listing of topics |
Fertilizer Economics - Tools for Management How can growers best react and handle the unexpected conditions arising from increased fertilizer prices? Read Full StoryEnviro-Briefs  These short articles present important facts and observations on the interaction among crop production, nutrients, and the Earth's air, water, and soil resources. Consumers, students, agronomists, farmers, and all who are interested in the environment will find this series informative and easy to read. Enviro-Briefs topicsImpact of Rising Nitrogen Prices  Natural gas represents a major portion of the cost of ammonia production, and concern continues about effects on nitrogen (N) fertilizer prices. Impact of Rising N Prices Fall Fertilization As the calendar turns to fall each year, most farmers and their advisers are preoccupied with harvest and all the related priorities that go with it. Of course that’s important, but fall is also prime-time to address some economic and management questions on crop and forage nutrition, tillage systems, fertilizer placement options, soil testing, and other practices.
