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.

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.
