A recent study by the University of Florida highlights the critical role of soil and nutrient management in growing organic leafy greens in high tunnel systems. These structures, resembling unheated greenhouses, shield crops from extreme weather and extend the growing season.
Leafy greens, a staple in the organic market, face challenges in Florida's subtropical climate, including high temperatures and sandy soils with low organic matter.
The research examined nutrient inputs, soil amendments, and cover crops like cowpea over three years to optimize growth and maintain soil health.
Results show that tailored nutrient strategies enhanced yields and nutritional quality, addressing key market demands. The study also emphasized balancing soil fertility with plant needs to prevent nutrient leaching and soil degradation, ensuring sustainable farming practices.
Dr. Xin Zhao, a horticultural sciences professor at the University of Florida, led this project. She stated, “Effective management strategies can help mitigate challenges, ensuring sustainable production for organic farmers.”
The findings offer actionable insights for organic farmers and agricultural advisors. Published in HortScience, the research contributes to advancing organic farming practices in high tunnels, supporting resilient agriculture.
