The Land-Potential Knowledge System (LandPKS) is a simple free and open sourceOpen source is a publicly accessible software design that can be modified and shared by multiple users. This allows the ... software tool and mobile application developed by USDA/ARS that supports land use planning and management. It includes modules that allow non-soil scientists to (a) determine the sustainable potential of their land (LandInfo), (b) monitor the health of their land (LandCover and SoilHealth), and (c) record management activities (LandManagement). The land potential assessments will be updated based on new evidence regarding the success or failure of new management systems on different soils. The knowledge engine, together with mobile phone applications and cloud computing technologies, facilitate more rapid and complete integrationSystem integration is defined in engineering as the process of bringing together the component subsystems into one syste... of local and scientific knowledge into land management.
