North Dakota s Grand Farm sounds off in US Senate hearing
The director of the Grand Farm research and ag innovation project in the Fargo, N.D., and Minnesota area testifies about potential federal partnerships in an April 29, 2021, U.S. Senate Appropriations subcommittee hearing in Washington, D.C. Among other things, the organization is working on meeting labor shortages in the sugarbeet industry by researching autonomous truck concepts. 9:46 am, Apr. 29, 2021 ×

The amount of fertilizer-nitrogen to be applied in-season can be estimated with the Late Spring Soil Nitrate Test, crop canopy reflectance sensing, or by use of crop model N tools, combined with fertigation.
Late Spring Soil Nitrate Test
LSNT has been available for more than 30 years and is used for corn production to assess the need for in-season N application. It has been less studied and used in Nebraska than in Iowa, and we advise the use of the Iowa State University guidelines. LSNT has been well-validated for medium and fine texture soils, but it is not expected to work well for sandy soil. Use this test as follows:
Plants like to suck up nitrogen, which is why we use it as a fertiliser. But animal urine often contains more than they can absorb, so the soil bugs take over, converting the nutrient to nitrates (which can leach into water) and nitrous oxide. The team, led by Beverley Thomson of On-Farm Research, know that some farmers have control over sheep’s grazing patterns, by timing when they move flocks into a paddock with fresh pasture. To recreate this, scientists fed 12 lambs either in the morning or the afternoon and monitored their urine and droppings. The team found 60 per cent of the nitrogen in the animals’ urine came during the 12 hours following their big meal, according to the
