SoilSense wins Rep. Andy Barr’s 2025 Congressional App Challenge in Kentucky’s Sixth District

Rep. Andy Barr has named Katherine Zhang, Eric Su, and Mukhil Ravichandran of Paul Laurence Dunbar High School as the winners of the 2025 Congressional App Challenge in Kentucky’s Sixth District. Their app SoilSense is a comprehensive farm management and community platform designed to bring modern technology to rural agriculture in a way that is useful, accessible, and practical for everyday farmers.

When asked what inspired the creation of SoilSense, the students said, “Our inspiration came from home. We grew up surrounded by the farmlands of Kentucky, the heart of America’s agriculture, and some of our family members are farmers themselves. There are so many apps for investing, fitness, or shopping, but few apps are designed to help rural farmers. We wanted to change that.

“Agriculture in Kentucky is far more than a way of life; it is the cornerstone of the state’s economy and rural identity. In 2019, the agricultural sector’s total economic impact on the Commonwealth was estimated to be $49.6 billion, about an 8.8 % increase from 2012. Cash receipts hit $8.3 billion in 2024, showing growth and diversity among farms. Yet despite its size and significance, the farming sector in rural Kentucky faces systemic support shortfalls that threaten productivity, sustainability, and equity. Many farms operate with tiny margins, which limits their ability to invest in new tools or weather shocks.

“A key barrier is the lack of access to modern infrastructure and digital support. Many farmers report inadequate broadband connectivity, limited technological training, and scarce affordable solutions tailored to their context. For example, studies show that costs, the complexity of new technology, and low digital literacy keep many small-scale farmers from using precision agriculture tools. Additionally, barriers such as pests, diseases, resource mismanagement, and unpredictable weather add to the vulnerability of rural farms. In short, the people who feed our state and nation often must do so without the support systems, tools, and community infrastructure that their role would greatly benefit from.

“During development, we spoke directly with Kentucky farmers who told us how technology often feels intimidating or irrelevant to them. Hearing their excitement about our prototype reminded us that accessibility matters just as much as innovation. This drove us to create a solution that meets the needs of farmers across the state.

“Ultimately, our inspiration came from the possibilities of AI and app design, as well as the people working tirelessly behind every field. Farmers feed the world, yet they’re often left behind in the digital revolution. We wanted to give them some support through a completely free app that promotes sustainability, strengthens local communities, and helps them work efficiently. This app ultimately aims at creating a vision for a future where technology grows hand-in-hand with the hands that grow our food.”

The 2025 Congressional App Challenge marked another record-setting year for the program. A total of 394 Members of the U.S. House of Representatives hosted App Challenges in their congressional districts, the highest level of participation in the program’s history. More than 13,800 students from across the country participated, submitting over 4,600 original apps focused on real-world challenges ranging from health and accessibility to education, sustainability, and civic engagement.

The Congressional App Challenge is an official initiative of the U.S. House of Representatives that encourages middle school and high school students to learn to code, explore computer science, and build practical technology solutions for their communities. Each participating Member of Congress selects a winning app from their district, and winning teams are invited to showcase their projects to Members of Congress, staff, and industry leaders at the annual #HouseOfCode celebration on Capitol Hill.

The Challenge is proudly bipartisan and reflects a shared commitment to expanding access to STEM education and preparing the next generation of American innovators for the future workforce. The program is a public-private partnership made possible through funding from the Broadcom Foundation, AWS, Infosys Foundation USA, theCoderSchool, Apple, and others.

The 2026 Congressional App Challenge will launch in May, and eligible students can pre-register for the competition now.
