The article discusses advancements in agricultural technology and research with a focus on growing potatoes in space and cost-effective soil analysis methods. Chinese researchers are using genetic engineering and the Whole-Body Edible and Elite Plant (WBEEP) technology to grow potatoes in space, aiming to make them more nutritious and edible. A study by the Soil Science Society of America introduces a simple and cost-effective method to assess soil condition by measuring carbon dioxide washout after re-waterlogging dry soil. This method can be used to evaluate soil health without the need for extra chemicals. Additionally, the article highlights the benefits of using organic nitrogen fertilizers produced from aquatic cyanobacteria, such as Tolypothrix, which can improve soil structure and reduce carbon emissions. A study led by ETH Zurich professor Christian Schöb demonstrates that mixed crops can lead to significantly higher yields compared to monoculture crops.
