Knowledge for sustainable land management – in your hands!

The LandPKS app helps users make more sustainable land management decisions allowing them to collect geo-located data about their soils, vegetation, and site characteristics; and providing useful results and information about their site. It also provides free cloud storage and sharing, which means that you and others can access your data from any computer from our Data Portal at

The LandPKS app does not require a data connection to be used, and users can upload their data when they next have connectivity. It currently includes three modules: Climate, LandInfo and LandCover, with more coming soon.

LandInfo makes site and soil characterization fast and easy! The LandPKS app walks the user through how to hand texture their soil, as well as document other important site characteristics. The amount of water the soil can store for plants and water infiltration rate for the soil is then directly calculated on the phone. In addition, users receive an outline of their soil texture by depth, which is important for making decisions on agricultural land.

LandCover is a simple tool for rapidly collecting and recording vegetation cover using a 1 meter or yard stick. The LandCover module walks a user through collecting vegetation data using a point-intercept method at each of 5 point at 20 locations in each ¼ hectare (3/5 acre) plot. Cover results are automatically calculated on the phone and delivered to users in a variety of graphs, including cover trends over time.

Learn more about the LandPKS app on the website. Training resources, including guides and online trainings, are also available on the website. The LandPKS app was developed by the LandPKS Team for the Land-Potential Knowledge System (LandPKS) with support from USAID and USDA-ARS.

Other Features Include:
A simple, primarily graphics-based interface that minimizes language and literacy requirements.
Embedded tutorials and explanations guide the user through the app, including soil texture by hand.
Offline data collection
Unlimited access to stored data via our Data Portal at
