How Manure Impacts Soil Aggregation
What's New with S Fertilizer Use?
April 5, 2018
When is applying sulfur likely to be profitable and when is it cutting into your potential profit? This brief shares information from more than 100 university trials verifying current university recommendations.
Nutrient Management for Organic Production
April 5, 2018
The NebGuide, Nutrient Management in Organic Farming, features information also of value to conventional production, including manure management, composting, non-traditional products, and crop rotation suggestions.
Cover Crop and CO2 Emissions
February 26, 2018
Do cover crops affect CO2 emissions from the soil and if so, under what conditions? These were among the questions addressed by university researchers monitoring CO2 emissions from cereal rye cover crops in irrigated and dryland no-till continuous corn treatments.
Corn Residue Removal and CO2 Emissions
February 26, 2018
University research looking at CO2 emissions from two types of residue removal (baling and grazing) compared with a control treatment found little day-to-day impact; however, when looking at cumulative data for the whole year, grazing did appear to affect cumulative CO2 emissions in irrigated crop-livestock systems. This data represents the first year of this study.
Fertilizer N Substitution Values of Land-Applied Organic Materials
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics on accounting for nitrogen from land-applied manure when determining soil nutrient needs for crop production.
Adaptation of Canopy Sensor-Guided In-Season Nitrogen Application for Manured Fields
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics on research on land application of manure to enhance soil nutrients for crop production.
Improved Use Efficiency of Applied Organic Nitrogen
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics about recent research to validate or adapt canopy sensor-guided in-season N application practices for fields with manure or other organic material applied and to improve the predictionof fertilizer N substitution for organic materials.
Crop Residue Removal: Impacts on Yield
December 8, 2017
A review of multiple research studies indicates that where moisture is not limited, residue removal can result in no yield reduction to yield increases for the subsequent crop. However, long-term residue removal has been shown to affect other production factors and it's recommended that even in minimal erosion areas, removing residue does impact other production factors and it's recommended that 2.4 tons/acre of residue be left in the field.
