LandPKS is a free modular mobile phone app connected to cloud-based storage, global databases, and models. It is comprised of three different modules: LandInfo, LandCover and LandManagement, with more modules planned for the future (SoilHealth and Biomass/Utilization).
LandInfo is designed for rapid soil (texture and color) characterization, soil identification, and for accessing soil and ecological site information. This module will: identify a soil based on location and user inputs; predict soil infiltration and plant-available water-holding capacity (AWC) at variable soil organic matter (SOM); determine land capability class (LCC) for sustainable land use planning and management; and determine soil color using the phone’s camera and a standardized reference card.
The LandCover module is for rapid vegetation monitoring (vegetation composition, plant height, canopy and basal gaps). It is compatible with methods used by the USDA NRCS and the Bureau of Land Management, and can be used for rangeland monitoring, natural resource conservation and crop residue monitoring.
The LandManagement Module is for on-farm record-keeping about inputs, management and yields (e.g., crops, fertilizer, lime, irrigation, rainfall, erosion control, tillage etc) and can be used for providing data summaries.
LandPKS is a free mobile app that allows farmers, ranchers, gardeners and other land managers as well as K-12 and university students to easily identify their soil, access NRCS soil information, record their management and precipitation, and monitor soil health and vegetation. The LandPKS app can be used by university and K-12 students as a digital educational resource. In partnership with the Asombro Institute for Science Education, LandPKS recently released a three-lesson module that engages students on fundamental land management topics using the app. The curriculum meets Next Generation Science Standards for grades 5 – 8, and it is also relevant for older students and adults.
With the recent addition of the LandManagement and SoilHealth modules, LandPKS now provides a complete package to support adaptive management for small farmers and others who either cannot afford or lack the time to learn and use more complex software.
Access to soil information is available by either creating a site or simply tapping a location on the map in the bottom menu. Adding information on the soil at your site to the LandInfo input module improves soil identification.
In the LandManagement calendar you can record plantings, harvest, tillage, fertilizer, weed and pest control, residue management, erosion control, precipitation and irrigation. Options such as the ability record irrigation in gallons, minutes or inches allow the app to be used by nearly anyone.
The SoilHealth and LandCover modules support rapid NRCS- and BLM-compatible monitoring of soil health, and vegetation cover, general composition, and structure.
A new data privacy option allows users to decide not to expose their data on the public data portal.

We are continuing to improve the app and welcome your ideas, suggestions for improvement, and stories of how you have used or could use LandPKS.
LandPKS development is led by the USDA-ARS Jornada Experimental Range in cooperation with the University of Colorado – Boulder, and New Mexico State University. The app can be downloaded from the iPhone App and Google Play stores. They can be reached at contact@landpotential.org and more information is available at LandPotential.org
