A multi-year study of organic N used in Nebraska crop production validated sensor guided in-season N application as a means to efficiently use the N available from manure and other organic materials. See what benefits they found, as well as considerations for use.
Nitrogen in manure requires some simple planning to insure it's given proper credit for offsetting commercial fertilizer inputs. This Water.unl.edu article offers key information for calculating N credit.
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.
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.
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.
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.
Briefs on university crop research, this week featuring flame weeding research in northeast Nebraska and the effects of liquid manure injection into a winter rye cover crop as tested in on-farm trials in Minnesota.
