Research Provides Insight on Growing Organic Leafy Greens in High Tunnels

A recent study by scientists at the University of Florida sheds light on how soil and nutrient management practices significantly influence the productivity and quality of leafy green crops grown in high tunnel organic systems, reports the American Society for Horticultural Science. This 3-year study examined a cowpea cover crop, as well as a range of soil amendments, nutrient inputs, and management techniques to determine their impact on organic crop performance in high tunnels. Results revealed that tailored and integrated nutrient management not only improved crop yields but also helped maintain the overall nutritional quality of organically-grown leafy greens. This study underscores the importance of balancing soil fertility and plant nutrient requirements, especially in high tunnel systems with sandy soils. Effective management strategies, the research suggests, can help mitigate challenges such as nutrient leaching and soil degradation, ensuring sustainable production for organic farmers.
