Nana Yaw O Kusi

Dr. Nana Kusi works for 1890 Research and Extension in the Sustainable Agriculture and Natural Resources Program as an extension agronomist.

He is dedicated to working closely with South Carolina farmers to enhance their crop productivity and overall agricultural success. He focuses on various key areas to optimize farming practices and improve sustainability.

One of Nana Yaw O Kusi's research interests is exploring the potential of chickpeas as an emerging crop for South Carolina farmers. By studying its suitability, cultivation techniques, and market opportunities, he aims to provide valuable insights to farmers seeking to diversify their crop portfolios.

Additionally, Nana Yaw O Kusi plays a vital role in determining soil carbon levels and finding ways to enhance soil carbon sequestration. Improving soil health, fertility, and productivity are essential aspects of his work, as he aims to guide farmers in implementing strategies that lead to better soil management practices.

As a resource person, Nana Yaw O Kusi offers guidance and support to limited-resource, socially disadvantaged, and underserved farmers in South Carolina, specifically focusing on high tunnel crop production and management. This specialized knowledge empowers farmers to maximize yields and optimize their resources.

Furthermore, Nana Yaw O Kusi serves as an educator, sharing knowledge about climate-smart agricultural practices and promoting regenerative and sustainable agricultural techniques. By highlighting the benefits of these practices, he assists farmers in adapting to a changing climate while ensuring the long-term viability of their operations.

With his expertise and commitment to agricultural advancement, Nana Yaw O Kusi provides valuable support to beginner farmers, ranchers, and veterans in South Carolina, helping them establish and sustain profitable agricultural businesses.
