July 07, 2015 In-furrow soybean fertilization’s impacts on nodulation and reduction in nitrogen fixation. Because soybeans are a legume and have the ability to fix nitrogen (N), fertilization with N is not a common practice. Plants don’t begin to fix much nitrogen until after the middle of June, and wet and cool soil conditions further hamper nitrogen fixation. Many growers are hesitant to apply fertilizer in-furrow either because of salt... |

July 07, 2015 As an aerial applicator I get a lot of questions on applying products on corn and soybeans and applying nitrogen has been a popular one. So it is an honor to be asked to provide this guest editorial to the Illinois Soybean Advisor. There is an ongoing challenge to build yield, protein and quality in our soybean production practices. In most of my company’s existence many of our activities have been in crop protection. While there are... |

July 07, 2015 Options for controlling large weeds in soybeans … Heavy and frequent rainfall throughout the month of June has made timely postemergence weed control in soybeans very difficult, if not impossible. Some producers have even resorted to aerial herbicide applications. To improve weed control and help manage resistant weeds the use of residual products and tank mixtures has become more common and needs to become routine. This year a... |

July 07, 2015 This was the year that not using residual herbicide at planting shows. Some farmers got the seed in the ground, but either did not apply a PRE or rains prevented them from applying it. And, unfortunately, there are still too many growers hoping that their post application would work. For several years now we have been telling growers to apply a PRE as a practice to manage weeds resistant to herbicide. And some of them have adopted this... |

July 07, 2015 Soybeans got off to one of the best starts I’ve seen since I started working as an agronomist. Emergence was good for all row spacing layouts, tillage styles, varieties planted, etc. We couldn’t have asked for a better start. However, with all the excess rain that we have had in June soybeans are going backwards fast. We have drowned-out areas, we have saturated soils leading to anaerobic soil conditions, we have fields with hail and/... |

July 02, 2015 May and June were challenging months because of all the rain. Soybeans either didn’t get planted, were planted late or growers had the option of taking prevented planting if they chose. But they also had the option of planting soybeans beyond the normal crop insurance deadline. In central Illinois the latest I have seen beans planted and make a harvestable crop is July 20th. In most years if you can plant into moisture by July 10th you... |
