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.
In This Issue of Better Crops ...Precision Ag tools supporting food security; remote sensing for semi-arid cereals; factors improving K uptake; 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.

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).
