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.
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.
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.
A range of technologies are available to reduce nitrous oxide emissions, but rather than focus specifically on emissions, the broader management and policy focus should be on improved N use efficiency and effectiveness—for lower nitrous oxide emissions per unit of crop and animal product, or per unit of land area.
"The advantage of developing the Nutrient Expert® in a participatory mode was that the partners were on-board from day one and ultimately ‘owned’ the innovation."
It is possible to improve crop recovery of applied N and reduce the risks for environmental N losses through careful soil and crop management, and a keen understanding of N loss pathways. Download this bulletin in Stewardship Specific series.
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.
This year our contest features some important changes. Photos and supporting information can be submitted until December 11, 2014 (Thursday, 5pm EST).
