Jim Elser's New Phosphorus Book Released
In "Phosphorus: Past and Future", world authorities on phosphorus sustainability Jim Elser and Phil Haygarth explain Phosphorus's involvement in biology, human health and nutrition, food production, ecosystem function, and environmental sustainability. The book provides an insider's take on this essential resource and why all of us need to wrestle with the wicked problems this element will cause, illuminate, or eliminate in years to come.

Big Data's FRST Step in Environmental Stewardship
NC State Professor Deanna Osmond, who helped to initiate and continues to advise STEPS, led a multi-university team in creating the Fertilizer Recommendation Support Tool (FRST). The primary goal of FRST is to increase soil testing transparency by promoting clear and consistent interpretations of fertilizer recommendations by removing political and institutional (public and private) bias from soil test interpretation and providing the best possible science in order to enhance end-user adoption of nutrient management recommendations.

Accessing Legacy Phosphorus in Soils
STEPS team members collaborated on a recent review paper that highlights the (1) current knowledge on the occurrence and bioaccessibility of phosphorus in soil, (2) legacy phosphorus transformations with fertilizer applications in relation to their potential bioaccessibility, and (3) approaches and challenges for accessing native soil phosphorus for crop production.

More Transparency Recommended for Gene-Edited Crops
STEPS team member Dr. Khara Grieger recently published a policy forum paper with Dr. Jennifer Kuzma in the journal Science calling for a coalition of various stakeholders to work together to provide basic information about gene-edited crops to lift the veil on how plants or plant products are modified and the use of gene editing in food supplies.
Why Is Transparency Needed?

ASU and MCC team up with USDA research service to expand agriculture education
Mesa Community College and Arizona State University have partnered with the United States Department of Agriculture-Agricultural Research Service (USDA-ARS) Arid Lands Agricultural Research Center (ALARC) to create new opportunities for agriculture education in the Valley. The collaboration, a result of a three-year, $682,313 grant, created the urban-agriculture nexus project, a course of study between ASU’s Ira A. Fulton Schools of Engineering and the MCC Sustainable Agriculture program.

Call receives prestigious CAREER Award
Dr. Douglas Call received a National Science Foundation (NSF) CAREER Award. The overall goal of Call’s CAREER project is to protect human and environmental health by developing treatment technologies that more completely degrade toxic organic pollutants in a cost-effective manner. Call’s primary focus will be on degrading chlorinated solvents, a broad class of chemicals used in everyday products such as paints, pesticides, and cleaning solutions.

Fabric Mulch Groundcovers Save Water
Water and nutrient management in Florida citrus is a challenging problem. A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) team is analyzing fabric mulch groundcovers for young lemon trees on a commercial scale. During the last year, the use of groundcovers has shown water savings of 50 percent when combined with soil moisture sensor irrigation scheduling.
