[ncss-tech] soilDB 2.9.3

andrew.g.brown@usda.gov (Andrew Brown) — Thu, 01 Oct 2026 15:58:05 GMT

A collection of functions for reading soil data from U.S. Department of Agriculture Natural Resources Conservation Service (USDA-NRCS) and National Cooperative Soil Survey (NCSS) databases.

[ncss-tech] rosettaPTF 0.2.0

andrew.g.brown@usda.gov (Andrew Brown) — Mon, 27 Jul 2026 14:29:28 GMT

Access the rosetta-soil Python pedotransfer functions from R. Rosetta is a neural network-based model for predicting unsaturated soil hydraulic parameters from basic soil characterization data (sand, silt, clay, bulk density, and water content). Predictions are made for the van Genuchten unsaturated hydraulic properties model, with uncertainty quantification via bootstrap ensemble. Designed for efficient batch processing of large datasets through vectorized computation and optional parallel processing.

[ncss-tech] SoilTaxonomy 0.2.8

andrew.g.brown@usda.gov (Andrew Brown) — Thu, 04 Jun 2026 20:50:47 GMT

Taxonomic dictionaries, formative element lists, and functions related to the maintenance, development and application of U.S. Soil Taxonomy. Data and functionality are based on official U.S. Department of Agriculture sources including the latest edition of the Keys to Soil Taxonomy. Descriptions and metadata are obtained from the National Soil Information System or Soil Survey Geographic databases. Other sources are referenced in the data documentation. Provides tools for understanding and interacting with concepts in the U.S. Soil Taxonomic System. Most of the current utilities are for working with taxonomic concepts at the "higher" taxonomic levels: Order, Suborder, Great Group, and Subgroup.

[brownag] rapr 1.1.3

andrew.g.brown@usda.gov (Andrew Brown) — Mon, 30 Mar 2026 15:17:13 GMT

Provides access to 'Rangeland Analysis Platform' (RAP) products for arbitrary extents via 'GDAL' virtual file system.

[ncss-tech] soilReports 0.9.2

andrew.g.brown@usda.gov (Andrew Brown) — Tue, 05 Aug 2025 22:40:25 GMT

R package container and convenience functions for soil data summary, comparison, and evaluation reports used mainly by NRCS staff.

[brownag] SSURGOPortal 0.0.6

andrew.g.brown@usda.gov (Andrew Brown) — Thu, 22 May 2025 22:57:23 GMT

Provides methods for downloading and interacting with the 'SSURGO Portal' Python tools.

[ncss-tech] jNSMR 0.3.1

andrew.g.brown@usda.gov (Andrew G. Brown) — Tue, 04 Mar 2025 21:25:09 GMT

Provides methods to create input, read output, and run the routines from the legacy Java Newhall Simulation Model (jNSM) for soil climate. Currently this package uses a modified version of the jNSM v1.6.1 which is available for download here: and the source code found here . The system requirements of the extraction and installation tools (Windows .EXE archive) at the official download link may not be met on your system but the core Java class files are stored in a platform-independent format (a Java JAR file; e.g. newhall-1.6.1.jar) which is a core dependency in this package. Several more recent modifications to the Newhall JAR file allow for higher throughput and more efficient batching of many simulations allowing for larger-than-memory raster-based inputs and outputs.
