About

Frank J. Coale is an Acting Assistant Dean at the College of Agriculture & Natural Resources at the University of Maryland, located in College Park, MD. He serves as an Extension Specialist in Environmental Science & Technology with a focus on soil science and environmental science. His research emphasizes soil phosphorus dynamics and the relationships among agronomic production practices and phosphorus over-enrichment of surface water resources. Dr. Coale has applied his scientific expertise to the study of on-farm nutrient management aimed at achieving efficient agronomic production while protecting water quality, particularly within the Chesapeake Bay watershed. His work involves the discovery and quantification of the impact of agronomic practices on phosphorus transport to threatened water resources, contributing to sustainable agricultural practices and water resource protection.

• Winter Annual Cover Crop Impacts on No‐Till Soil Physical Properties and Organic Matter

  Soil Science Society of America Journal · 2012-10-19 · 167 citations

  article

  The inclusion of winter annual cereal cover crops (WCC) in grain crop rotations is a common management practice promoted to protect soil resources and enhance water quality. However, the effects of long‐term incorporation of WCC into no‐till grain crop rotations on soil physical properties are not well established. We evaluated the long‐term effects of WCC on soil physical properties after 13 yr of use at three locations in Maryland, USA. Continuous maize ( Zea mays L.) was the summer grain crop…

• Nutrient Removal by Corn Grain Harvest

  Agronomy Journal · 2003-05-01 · 142 citations

  article

  Effective nutrient management requires an accurate accounting of nutrients removed from soils in the harvested portion of a crop. Because the typical crop nutrient values that have historically been used may be different under current production practices, a study was conducted to measure nutrient uptake in grain harvested in 1998 and 1999 from 23 site‐years in the Mid‐Atlantic region of the USA. There were 10 hybrids included in the study, but each site grew only one hybrid each year. Corn ( Ze…

• Soil Test Calibration for Predicting Corn Response to Phosphorus in the Northeast USA

  Agronomy Journal · 2006-02-07 · 63 citations

  articleOpen access

  The consensus of soil fertility specialists working in the northeast USA was that soil testing and recommendation systems for P needed to be reexamined because of recent changes in soil testing methodology in the laboratory and corn ( Zea mays L.) production technology in the field. Soil tests (M‐COL, MM‐COL, B‐ICP, M1‐ICP, and M3‐ICP) were performed by either colorimetry or inductively coupled plasma (ICP) emission spectroscopy on samples from soil test calibration studies conducted during 1998…

• Managing manure for sustainable livestock production in the Chesapeake Bay Watershed

  Journal of Soil and Water Conservation · 2012-03-01 · 61 citations

  articleOpen access

  Manure presents one of the greatest challenges to livestock (dairy and beef cattle, swine, poultry, equine, sheep, llamas, etc.) operations in the Chesapeake Bay Watershed, serving both as resource and liability. The Chesapeake Bay is threatened by excessive nutrient loadings, and, according to the US Environmental Protection Agency (USEPA), manure is the source of 18% of the nitrogen and 27% of the phosphorus entering the Chesapeake Bay annually (figure 1) (Chesapeake Bay Program 2010). Develop…

• Determination of Phosphorus Source Coefficients for Organic Phosphorus Sources

  Journal of Environmental Quality · 2004-01-01 · 56 citations

  articleSenior author

  Phosphorus losses in runoff from application of manures and biosolids to agricultural land are implicated in the degradation of water quality in the Chesapeake and Delaware Inland Bays. We conducted an incubation study to determine the relative P solubility and bioavailability, referred to as P source coefficients (PSCs), for organic P sources, which are typically land-applied in the Mid-Atlantic USA. Nine organic and one inorganic (KH2PO4) P amendments were applied to an Evesboro loamy sand (me…
