Recently, the question has been raised of whether or not agriculture should be using potassium (K) fertilizers. Dr. T.S. Murrell, IPNI Northcentral Director, has prepared a review of this issue examining how the soil fertility and plant nutrition science determines if or when K should be applied.

IPNI responds to a recent TED talk related to the issue of phosphorus use, and welcomes discussion of issues associated with phosphorus fertilizer use and the opportunity to clarify public perception of those issues.
The book Southern Forages was first introduced in 1991 and has since gained wide recognition as a practical and reliable source of information on modern forage crop management. This book is now available in Spanish. (FORRAJES DE LAS AMÉRICAS)
A basic understanding of the reactions of nitrogen in soils provides a solid foundation for making wise nutrient stewardship decisions. Nitrogen Notes is a series of fact sheets written by IPNI staff that covers the major nitrogen fertilizer transformations that occur in crop production.
Nutrient Expert® is an easy-to-use, interactive, and computer-based decision support tool that can rapidly provide nutrient recommendations for an individual farmer field in the presence or absence of soil testing data.
The 4R Research Fund was established by the fertilizer industry to help determine sustainability indicators and environmental impact data for implementation of 4R Nutrient Stewardship across North America.
Introducing the 4R Nutrient Stewardship Concept to Smallholder Farming Systems of Sub-Saharan Africa
Dr. Shamie Zingore, IPNI Director, Sub-Saharan Africa Program discusses how the 4R Nutrient Stewardship concept can be specifically adapted to smallholder farming systems.
Dr. Shamie Zingore, IPNI Director, Sub-Saharan Africa Program, leads us through the region’s current challenges and discusses the limitations of smallholder farming systems and their surrounding infrastructure.
Twenty six (26) graduate students have been named to receive the IPNI Scholar Award in 2013, 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.
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.
