The Water-Soil Health Connection
September 29, 2017
Cover crops, crop rotation, and other means for improving soil health are among the research areas pursued by the Soil Health Institute, a non-profit organization supporting soil stewardship and advancing soil health. Learn more about its work and the research it's spotlighting this week.
Managing Nitrogen to Reduce Losses as Nitrous Oxide
September 18, 2017
Nitrogen is a key factor in farm management and economics. One of the most expensive inputs for corn production, it can be easily lost to the environment. One avenue for losing N, as nitrous oxide, has an impact on our climate as a greenhouse gas. Successful strategies for reducing N losses, especially as nitrous oxide, benefit both farmers and the environment.
Fertilizer Management for Winter Wheat
August 29, 2017
With winter wheat planting drawing near, it's time to collect soil samples and determine fertilizer needs. Use the nitrogen and phosphorus information to guide your strategy.
Evaluating N Management with the Corn Stalk Nitrate Test
August 23, 2017
When is this test best used? Often it may be well used to compare nitrogen uptake between two practices in corn.
How Manure Impacts Soil Aggregation
July 6, 2017
Researchers compare differences between soils fertilized with three types of manure versus commercial products and note four benefits, including an increase in water-stable large macro-aggregates that hold P differently.

Iowa Releases New Publication on Use of the Late Spring Soil Nitrate Test
June 8, 2017
Following heavy spring rains, farmers may be interested in testing for soil nitrogen availability. This article notes a new publication from Iowa State University on using the Late Spring Soil Nitrate Test (LSNT) as well as other options for assessing soil nitrate.
Risk of Nitrate Leaching Across Nebraska as of May 21, 2017
May 25, 2017
Following heavy spring rains UNL soil scientists model potential loss of nitrate-N to soil leaching, finding an average 14% loss from mid-April levels, with three sites with much higher losses.
