Study explores nutrient impact on leafy greens' growth

Florida researchers have discovered how high tunnel systems improve organic leafy greens' growth, quality, and sustainability. These greenhouse-like structures protect crops from harsh weather and extend growing seasons.

Florida's subtropical climate, marked by extreme heat, humidity, and sandy soils, poses challenges for organic farmers. Over three years, scientists tested cowpea cover crops, nutrient inputs, and soil amendments to determine their impact on leafy greens in high tunnels.

The study revealed that integrated nutrient strategies significantly enhanced crop productivity while maintaining nutritional value. This approach also minimized nutrient leaching and supported soil health, essential for sustainable farming.

Dr. Xin Zhao, who led the study, explained, “Effective management strategies can help mitigate challenges, ensuring sustainable production for organic farmers.” These findings address the growing demand for organic produce while helping farmers adapt to challenging environmental conditions.

Published in HortScience, this research provides valuable guidance for organic farmers, offering practical solutions for optimizing high tunnel farming. Learn more about the study and related insights at the University of Florida’s Agricultural Research Department.

Demco's dual auger grain cart is designed for unloading efficiency, operator visibility, and safety in the field.

This dual-auger design features both an unload auger and a floor auger for enhanced grain cleanout and consistent flow, and the 22-inch unload auger is capable of moving up to 600 bushels per minute.

Farmers can also choose between right or left-handed unload options—right-handed unload improves visibility from the tractor cab. A new design allows both vertical and horizontal movement for precise grain placement during unloading.

Another key feature is the built-in fire safety system; a 300-gallon onboard water tank with a hose reel that provides field-ready fire suppression capability.

These dual auger grain carts are available in 1100, 1300, 1500, 1700, and 2200 bushel sizes.
