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.

Video: Is China Buying US Soybeans + USDA Nov 14th Crop Report could be “Game Changing”

After a week of a U.S./China trade truce, markets/trade is skeptical that we have not seen a signed agreement nor heard much from China or seen any details. There are rumors that China is buying soybean futures & not the physical. Trust in Trump?
12 MMT of U.S. soybean purchases by China by year-end is better than 0 but we all need to give it more time and give it a chance to unfold. China did lower the tariffs on Ag and is buying U.S. wheat and sorghum.
U.S. supreme court could rule against Trumps tariffs, but the Trump administration does have a plan B.
U.S. government shutdown is now the longest in history at 38 days.
But despite a U.S. government shutdown we will be getting a USDA November crop report next Friday and it could be “game changing.” If the USDA provides a bullish surprise with lower U.S. corn and soybean yields and ending stocks that are lower than expected both corn and soybean futures will break out above their ceilings at $4.35/bu and $11.35/bu respectively.
The funds continued their selling in live and feeder cattle futures on continued fears that the Trump administration want to lower U.S. beef prices. The fundamentals have not changed, only market psychology has.
Stocks markets continue to worry about a weak U.S. job market, but you can blame ChatGPT for that. In the future, we will have a more efficient, productive and growing economy with a higher unemployment rate until we have more skilled AI workers.
After 34 new record highs in the S & P 500 and 124 new records in the NASDAQ in 2025 we are back to a correction and investor profit taking as AI valuations may have gotten too stretched near-term ahead of NVDA’s 3rd quarter earnings announcement on Nov. 19th. But this is not an AI bubble.
