Soil Sampling Behind the Combine (08/17/17)

Early crops are starting to be harvested and soil sampling may begin at any time. Years ago, NDSU published a ‘sampling date adjustment’, meant to allow for additional nitrate to develop later in the fall should a sampler decide to collect soil before mid-September.

Cover Crop Exchange (8/03/17)

At one of Dr. Wick’s Soil Health Café Gatherings this past winter, some of the attendees talked over the use of cover crops for livestock and at least in eastern North Dakota during years of excess water, cover crops were helpful in reducing soil water, maintaining soil cover to prevent wind erosion and perhaps serving as fall cattle feed.

Options Limited for Rescue Treatments for IDC in Soybeans (06/22/17)

Reports of iron deficiency chlorosis (IDC) of soybeans are coming in. The unifoliate leaves of soybeans are usually green, being fed by iron reserves in the seed, but as the trifoliolate leaves appear, chlorosis often develops when soybeans are grown on alkaline, poorly-drained soils. Iron is very immobile in the plant, so the deficiency appears first on the youngest leaves.
