Apps Help Growers Share Knowledge On Land Productivity

USDA’s Agricultural Research Service (ARS) soil scientist Jeff Herrick and colleagues recently released the first two of a suite of mobile phone apps that, once all are issued, will connect agricultural producers around the world and provide them with shared knowledge on ways to maximize their land’s productivity while protecting its resources for future generations.

However, other platforms, including iPhones, may be available by year’s end, Herrick said, with ARS’s Range Management Research Unit in Las Cruces, NM.

Herrick helped develop, test and release the apps as part of a five-year, multi-organization project called the “Land Potential Knowledge System” (LandPKS). The U.S. Agency for International Development, New Mexico State University, USDA-Natural Resources Conservation Service, Africa Technology Policy Studies Network, and World Agroforestry Center are among the participants.

“The LandPKS is a global network of open-source databases and computer simulation models that anyone with a mobile phone and a wireless or cellular data connection will be able to access,”  Herrick said.

The apps use the latest in digital soil mapping, GPS-enabled camera functions, and Cloud-computing technology, but require no special training — thanks to picture-matching, drop-down menus, explanatory video, and multiple-choice questions.

With LandInfo, for example, users can collect and share soil and land-cover information as well as gain access to global climate data. The app also provides some useful feedback, including how much water the soil can store for plants to use, average monthly temperature and precipitation, and growing season length.

LandCover simplifies data collecting for use in land-cover inventories and monitoring. In fact, a yard or meter stick with five notches is all that’s needed to document tree, grass, bare-ground and crop-residue cover. The app automatically generates basic indicators of these cover types on the phone and stores the data on servers that are accessible to users worldwide.

A future app (LandPotential) will use the LandInfo data together with Cloud-based models and additional knowledge bases to help users identify and select management systems that increase production while reducing soil erosion.

Herrick said this type of shared knowledge will become especially important as agricultural producers seek to meet the food, fiber, fuel, and feed needs of a growing world population projected to reach 9 billion individuals by 2050.
