Data Bases

Database structure, development, transformations, mining, and maintenance for both NLEW and PLAT are provided by David Crouse of the Soil Science Department at NC State University.

Funding

Funding for the programming of this tool was provided through the NC Department of Environment and Natural Resources as pass through 319 USEPA funds and the Neuse Crop Management Project, which is funded in part by the Pew Charitable Trust through the Center for Agricultural Partnerships as well as the North Carolina Clean Water Management Trust Fund.

Nitrogen Loss Estimation Worksheet

Development

The Nitrogen Loss Estimation Worksheet software (NLEW) Field-scale version software has been developed under the auspices of the Neuse Basin Oversight Committee - Agricultural Rule 0.0238. The Neuse Basin Oversight Committee asked a joint interagency committee to develop NLEW. The development of this tool has been cooperative effort between the N.C. Department of Agriculture, N.C. Department of Environment and Natural Resources, N.C. State University, and USDA – Natural Resource Conservation Services. This software was designed to meet the nitrogen loss assessment and best management practice-tracking requirement under the Agricultural Rule 0.0238 for those entities participating in the Local Option.

Personnel Involved In The Development of NLEW

The conceptual development of NLEW should be attributed to the following individuals: D.L. Osmond, N.N. Ranells, S.C. Hodges, and E.J. Kamprath (NCSU); L. Xu (NCDENR – Division of Water Quality); T.E. Jones (formerly NCDENR – Division of Soil and Water Conservation); J.R. Hansard (USDA-NRCS), and; J.R. Cummings (NCDA&CS).

The overall software design and programming was by S.H. Pratt and K. May (Understanding Systems, Inc). Algorithms for the calculations within the program were provided by D.L.Osmond and L. Xu (NCSU and NCDENR).

Acknowledgements

We would like to express our appreciate to Natalie Dotson and Kelly Fulford from the North Carolina Division of Soil and Water Conservation who tested the software and made useful and important suggestions. We would also like to thank Noah Ranells (Crop Science Department, NCSU) for reviewing the algorithms.

Phosphorus Loss Assessment Tool

Development

The software for the Phosphorus Loss Assessment Tool (PLAT) has been developed under the North Carolina Phosphorus Loss Assessment Committee formed to support the USDA-NRCS 590 Nutrient Management Standard. The conceptual development of this tool has been cooperative effort between the N.C. Department of Agriculture, N.C. Department of Environment and Natural Resources, N.C. State University, and USDA – Natural Resource Conservation Services.

Personnel Involved in the Conceptual Development of PLAT

The conceptual development of PLAT should be attributed to the Phosphorus Loss Assessment Committee that includes the following individuals: W. Gilliam, J. Havlin (chair), S. Hodges, A. Johnson, G. Kamprath, R. Mikkelsen, N. Nelson, and D. Osmond (NCSU-Soil Science Department); R. Evans, J. Parsons, W. Skaggs, and P. Westerman (NCSU-Department of Bio & Ag Engineering); S. Coffey and C. Pierce (NCDENR – Division of Soil and Water Conservation); J. Hansard and L. Price (USDA-NRCS), and; R. Reich and D. Hardy (NCDAC&S).

S.H. Pratt and K. May (Understanding Systems, Inc) provided the software design and programming. Algorithms for the calculations within the program were provided by S.H. Hodges and D.L.Osmond (NCSU).

Acknowledgements

We would like to express our appreciate to all the employees of NC Cooperative Extension, USDA-NRCS and Soil and Water Conservation District employees that helped with the field sampling for PLAT.
