The DEADLINE to apply for the IPNI SCHOLAR AWARD is fast approaching... JUNE 30, 2013. This award of USD 2,000 (two thousand dollars) is an annual competition amongst students enrolled in graduate degree programs supporting the science of plant nutrition and crop nutrient management.

A nutrient cycle is the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulated by food web pathways that decompose matter into mineral nutrients.

Nutrient Source Specifics are one-page fact sheets highlighting various fertilizers and nutrient sources. Written by IPNI scientific staff, these items are primarily for educational use by a non-technical audience. Consult with a local expert regarding specific recommendations on nutrient use.

The peer-reviewed publication is now available in a single hardcopy book form and is comprised of 11 chapters within three themed sections including: 1) Food and Nutrition Security, 2) Functional Foods, and 3) Risk Reduction.

A superb cup of coffee. The process is as much an art as a science.

This manual is a wire-bound, +130 page (8½ x 11 in.) book filled with illustrations, learning modules, and case studies.

This publication looks at the processes shaping the current nutrient situation and the resulting requirements as world food production evolves during the next 40 years.

Without adequate plant nutrition, the world would produce only about half as much staple foods and more forested lands would have to be put into production.

Sodium nitrate was one of the first commercially available inorganic nitrogen (N) fertilizers. It was very important in plant nutrition before the discovery of ammonia synthesis by the Haber-Bosch process in the early 1900’s. Sodium nitrate is a naturally occurring mined product, and as such is used to provide a portion of N nutrition in some organic cropping systems.

Contains key photos of classic nutrient deficiency documented from research plots and farm fields for 14 common crops. It also provides supporting text and illustrations of nutrient deficiencies. The app can be downloaded and viewed on iPhone, iPad, or iPod Touch devices.
