CropsGreg Stewart said dry spells can cause potassium deficiency even in well-testing soils, and questioned guidelines that recommend replacing crop removal only once soil-test potassium falls to about 75 ppm.
CropsAcross 117 sites from 2019 to 2022, corn yield response plateaued near 18 ppm soil phosphorus, close to the state's 16 ppm critical level; every site under 4 ppm responded, only a third above 30 ppm did.
CropsAgronomist Brian Ternus says one plot's winner can mislead; look for hybrids that rank in the top quarter across many plots, plant a mix, and ask how each plot was managed.
CropsA machine-learning study projects European sorghum yields rising from 3 to as much as 3.8 tonnes a hectare by 2050-2100, with land suited to high, stable yields growing from 22% to up to 34% of cropland.
CropsThe new lines, CML661A to CML665B, are offered to breeding programmes as parents for hybrids; one already parents hybrids released in India, Nepal, Pakistan and China.
CropsAt the Conservation Agriculture Research Forum in Potchefstroom, researchers using the DRiS method and farmer trial leaders argued that soil nutrient ratios and on-farm testing matter more than high fertiliser rates.
CropsBioPower Energy signed a memorandum with the U.S. Grains & BioProducts Council to source half to all of its feedstock from US suppliers, with a floor of 1 million tonnes of corn a year.
AgrotechThe French startup sprays naturally occurring plant compounds on corn, soybeans, sunflower and wheat before water stress, and reports water-use efficiency gains of 17% to 30% in this season's European trials.
Vermont-founded IMIO applies concentrated, freeze-dried microbes to crop residue so that the nitrogen, phosphorus and potassium locked in stalks are released in time for the next crop.
CropsPioneer specialists say 2026 brought local outbreaks rather than last year's widespread pressure: leaf diseases in the rainy eastern Corn Belt, crown rot in the drought-hit west and late southern leaf blight in the South.
CropsHungarian Prime Minister Peter Magyar says Zelenskiy asked Poland, Romania, Slovakia and Hungary to allow transit of Ukrainian grain, and that Hungary would not object if cargoes only pass through.
AgrotechUniversity of Minnesota researchers working with PepsiCo built CHIP-NCM, which predicts masa dough moisture from scans of raw grain so processors can adjust before production.
