This series includes in-depth, critical reviews by IPNI Scientists on current issues related to plant nutrient science.
This year our contest features some important changes. Photos and supporting information can be submitted until December 11, 2014 (Thursday, 5pm EST).
The video explains how farmers make 4R decisions (i.e., decisions on applying the Right source at the Right rate, Right time, and Right place) to minimize greenhouse gas emissions resulting from their nitrogen fertilizer applications.
Thirty (30) graduate students have been named to receive the IPNI Scholar Award in 2014, with the most widespread geographic distribution ever for the award. The individual awards of US $2,000 are given to graduate students in sciences relevant to plant nutrition and management of crop nutrients.
The calculator estimates crop nutrient removal of nitrogen (N), phosphorus (expressed as P2O5), potassium (expressed as K2O), and sulfur (S) for a broad, and continually expanding, list of field crops.
The video, launched during the African Green Revolution Forum (AGRF) in Ethiopia, is a call to African Leaders to note and address the bottlenecks that continue to throttle expanded fertilizer use by smallholder farmers.
Sunflower crop holds a great promise in meeting the shortage of edible oils in India whilst also benefitting the small and marginal farmers economically. A paper published recently brought out the positive impact of ample N, P, and K fertilization on sunflower yield, economics, and soil nutrient balances in an alluvial soil in West Bengal, India.

This quarterly publication features current issues in plant nutrition. In this issue, read about the nitrogen nutrition for winter wheat; why micronutrient availability is patchy in fields; which is better for soybeans: fall or spring applications?; 4R and precision agriculture—where's the payback?; and much more...
Dr. Shamie Zingore, Director, IPNI Sub-Saharan Africa Program, recently co-authored an article that reviews key literature on smallholder farm typologies focusing on three countries (Kenya, Malawi and Zimbabwe) to gain insights on opportunities for crop production intensification and the importance of developing farm-specific nutrient management practices.
Featuring the best research in plant nutrition... In this issue, read how Precision Ag tools are supporting food security; how remote sensing is being used for semi-arid cereals; about factors improving K uptake; about the value of crop straw ...and much more.
Featuring videos, e-books, manuals, slide sets, articles, and everything developed by IPNI and other cooperators on 4Rs—a concept that developed through a long history of cooperation between fertilizer industry and the scientific community and is being rapidly adapted throughout the world for increased crop yields, farm profits and better environment.

Stewardship Specifics are condensed, one-page bulletins providing scientific reviews of issues impacted by nutrient stewardship. Stewardship Specifics are written by IPNI staff and are intended to provide balanced assessments of current and emerging topics related to nutrient use, crop production, and environmental protection.
A basic understanding of the reactions of nitrogen in soils provides a solid foundation for making wise nutrient stewardship decisions. This series of fact sheets, written by IPNI staff, covers the major nitrogen fertilizer transformations that occur in crop production.
