Although about 80% of the nitrogen in the air can not be directly used by ordinary plants, peanuts,but soybeans, alfalfa and other leguminous plants can only convert the molecular nitrogen in the air into ammonia nitrogen that can be used by plants through symbiotic nitrogen fixation with rhizobia. After the seeds germinate and take root, rhizobia invade the roots from the root hairs. Under certain conditions, they form nodules with nitrogen fixing ability. Under the action of nitrogen fixing enzymes, the bacteroids in the nodules convert molecular nitrogen into ammonia nitrogen. At the same time, each nodule is a miniature nitrogen fertilizer plant, which continuously delivers nitrogen to plants for utilization...

Soybean rhizobia (Latin name: Bradyrhizobium japonicum) are in the family bradyrhizobiaceae, the genus of soybean rhizobia. Rhizobia in soybean are live microbial agents rhizobia inside root nodules have mutually beneficial symbioses with legumes: organic matter that legumes make by photosynthesis, supplied in part to rhizobia; Rhizobia, which make ammonia through biological nitrogen fixation, then feed legumes. Rhizobium invades the roots of the host, stimulating some cells of the root cortex and the central column sheath, causing the strong growth of these cells, causing local enlargement of the roots to form nodules; Rhizobium settles in the roots, and plants supply Rhizobium with mineral nutrients and energy Rhizobium fixes the free nitrogen in the atmosphere and provides nitrogen nutrients for the plants. The two are in equilibrium in the antagonistic parasitic relationship and exhibit symbiosis. Rhizobia belong to symbiotic nitrogen fixation, nitrogen fixation efficiency is the highestBenefits Increase production and efficiencyAccording to the field demonstration results, the application of rhizobia in soybean can increase the soybean yield by more than 10%, the protein content of soybean can be increased by 2%, the crude fat content can be increased by 1-2%...

Here on AgFuse, I’ve responded to a number of AgAnswers questions regarding soybean fungicides, management practices, and the general history of soybeans being farmed in America. I thought I’d round up these answers together so they’re conveniently linked in one spot. “Soybean Fungicides for Frogeye Leaf Spot at R3?”Here you'll see helpful pointers for identifying the symptoms of frogeye leaf spot, applying the right fungicides prudently, and adjusting your management practices for overall optimization. “Is Topguard the Best Fungicide for Frogeye Leaf Spot in Soybeans?” Here's an introductory look at understanding efficacy ratings, being aware of multiple diseases in your fields, factoring in your crop rotation, and avoiding resistance. “Soybean Fungicides for Septoria Brown Spot at R5?”Here's a helpful review of the disease itself, symptoms to look for, fungicide treatments to consider, timing to pay attention to, and general management practices that will further support your operation...

“We don’t have it all figured out just yet,” Monte Bottens, founder of Ag Solutions Network admits, referencing a weedy field of soybeans at harvest this fall. Bottens Family Farm, in the heart of Illinois farm country, made a commitment to remove glyphosate from their operation two years ago. A couple of specific cover crop burndown needs on a select number of acres required them to use a small amount this last season but, “other than that, we have stopped using glyphosate,” Monte said. “I think farmers across the country are all passionate about farming and trying to do the right thing. But when it came down to it, we just knew we needed to do better and this was the next thing we wanted to tackle in furthering our commitment to improving soil and human health...
