The spike in nitrogen fertilizer prices over the past month has prompted many growers to think about switching more acres to soybean in 2026. The high nitrogen fertilizer prices are squeezing the potential profitability of any crop requiring nitrogen fertilizer, such as corn, dry bean, canola, or wheat. The symbiotic nitrogen fixing behavior of soybean […]
This article originally appeared in the AGVISE Laboratories Spring 2024 Newsletter. Over the winter months, we received a lot of questions about the increasing soybean cyst nematode (SCN) egg count trends across the region. Soybean cyst nematode is the most damaging soybean pest in the United States, and the problem is becoming worse. The AGVISE […]
This article originally appeared in the AGVISE Laboratories Winter 2022 Newsletter This is the third year of our soybean cyst nematode (SCN) resistance project. Each year, we have flagged spots in soybean fields and collected paired SCN soil samples in June and September. If the SCN egg count increases through summer and into fall, we […]
Soybean cyst nematode (SCN) is a microscopic parasitic worm that attacks the roots of susceptible soybean and dry edible bean, causing unseen or unexplained yield losses. Soybean and dry edible bean are naturally susceptible to SCN, but through plant breeding, most soybeans have some level of resistance, varying in level from good to poor. The […]
Soybean Cyst Nematode (SCN) is the number one crop yield-reducing pest in soybean production. Potential crop yield loss to SCN is expected to rise as more and more populations of SCN overcome the PI88788 resistance source. The Peking resistance source is not as common as the PI88788, but it is becoming incorporated into more soybean […]
Originally featured in the Winter 2020-2021 AGVISE Laboratories Newsletter In 2019, AGVISE Laboratories investigated if popular soybean varieties with PI88788 or Peking SCN-resistance traits were effectively providing protection from soybean cyst nematode (SCN) and found that a number of the varieties failed to do so. We expanded the project in 2020 with cooperation from agronomists […]
Among crops grown in the northern Great Plains, small grains (cereals) are the most susceptible to copper deficiency. Copper (Cu) is an essential micronutrient required in small concentrations for plant growth and reproduction. Copper deficiency symptoms in cereals include pale yellowing, wilted and twisted leaf tips, and malformed seed heads. Severe copper deficiency will stop […]
In 2020, there are again widespread acres of Prevented Planting (PP) in North Dakota and northwest Minnesota. Farmers are now making plans to plant cover crops on unplanted cropland in the next few weeks. It is important to establish cover crops on PP fields because growing plants help reduce the chance these fields will be […]
