In 2015, Caroline Matenchi faced a challenge that would lead to a groundbreaking innovation in agriculture. While on a study break, Caroline thought of a way to fund her education by growing vegetables in her parents' backyard. Despite her efforts, the crops such as cabbage, potatoes, tomatoes, and spinach failed to thrive. Even with fertilisers and regular watering, nothing seemed to grow. This failure sparked her curiosity and determination to understand the science behind soil health.

Returning to her studies at the University of South Africa (UNISA), Caroline delved into research on soil types and methods to improve crop yields. Her passion and persistence culminated in the development of the Pedology 7-in-1 Environmental Sensor, a smart device designed to assess and enhance soil quality. "I submitted my idea to an innovation challenge at UNISA and was thrilled to be among the top five winners, receiving a seed grant to bring my project to life," she shares.

With the support of the seed grant, Caroline returned to her community, collaborating with local farmers to improve their soil and manage their gardens more effectively. Her company, AGR-smart tech, now conducts outreach programs in rural areas, equipping community members with essential skills and knowledge in soil treatment and health.

Despite her success, Caroline faced significant obstacles as a female entrepreneur in the agro-tech industry. "The support in agri-tech often favours those with more experience or connections in urban agriculture," she explains. Funding and collaboration opportunities were scarce, but Caroline's resilience and belief in her mission motivates her to keep moving forward.

Her advice to other female entrepreneurs is deeply rooted in her experiences: "We are the mothers of this earth. Every solution we develop is for future generations and our communities. No matter the hardships we face, our perseverance will always lead to success," she says.
