July 21, 2017 Will high soil test K levels protect against SDS or other diseases? More is not always better. With nutrient deficiencies becoming more commonplace, we are often reminded of the need to keep adequate levels, as well as the correct application timing, of macronutrients and micronutrients to supply the proper nutrition needed for optimal performance of today’s higher yielding soybean varieties. Dan Davidson recently reviewed... |

July 21, 2017 Nearly every new technology brings its own challenges and learning curve—and the first full season with dicamba-tolerant soybeans and approved over-the-top herbicide formulations is a reminder of that fact for farmers, researchers, ag retailers and farm organizations. With the new dicamba-based herbicides under a two-year U.S. EPA label, and with weed management challenges growing every day, it’s essential for the industry to get this... |

July 17, 2017 When scouting fields in July, look for these symptoms. They may be big problems or really no problems at all. As we move further in the growing season and start scouting soybean fields we may see symptoms of disease, insect infestation or environmental conditions. Some are easily recognized while others can be confused with something else. Some symptoms are more uncommon and not seen every year. Below is a guide of soybean... |

July 15, 2017 So, what happens to soybean plants that are stressed during the summer? The 2017 season has been stressful and July looks to be warmer and drier than normal. First it was wet and cold early this spring, which prevented planting or stressed emerging soybean seedlings. When they finally got planted it turned dry and hot. Soybean development is behind and plants are smaller than they normally would be by now. However, they are... |

July 13, 2017 Soybean plants have the ability to form a symbiotic relationship with nitrogen-fixing Rhizobia bacteria, which cause the small swellings on the root system called nodules. The soybean plants are developing rapidly and nodules will start to form shortly after plant emergence. If the plant is around 6 inches tall with the first or second true leaves (trifoliolate leaves) unfolded, nodules will start to actively fix Nitrogen (N) gas... |

July 12, 2017 Combining strategies will produce higher soybean yields. Obtaining higher soybean yields is a great goal. However, the true challenge is doing it sustainably and profitably, year after year and beyond. Think of each soybean plant as a factory. As with any factory, it’s all about how efficiently the factory produces an output and overcomes its potential limiting factors. When evaluating a soybean plant or “soybean seed factory,”... |
