Can I Irrigate Animal Manures On Growing Crops? June 27, 2018

Recent heavy rains have many feedlot holding ponds full and operators looking for irrigation options to apply animal manure during the growing season. Here are some considerations for applying diluted animal manures without damaging the crop.

Land-applied manure — Research to validate or adapt canopy sensor-guided in-season N application practices for manured fields was evaluated in two trials.

Adaptation of Canopy Sensor-Guided In-Season Nitrogen Application for Manured Fields May 8, 2018

Land application of organic materials for soil management in Nebraska is important.

Figure 1. Land-applied manure from finishing 5 million beef cattle per year in Nebraska contains the equivalent of 150 lb/ac/yr N applied to 1.2 million acres.

Land application of organic materials for soil management in Nebraska is important for several reasons:

Manure’s Impact on Yield, Nitrogen, and Carbon May 3, 2018

If manure is applied at rates equal to or less than the nitrogen (N) requirement of a crop, can manure produce environmental benefits over commercial fertilizer? This article summarizes the "Take Home Messages" from a paper summarizing 141 studies relative to the question.

Improving the Efficiency of Applied Organic N April 11, 2018

University of Nebraska research is offering new insights into plant use efficiency of organic N resources such as livestock manure, municipal bio-solids, and others. The studies continue through 2018 and are expected to influence changes in university recommendations.
