Crop Production

When talking about manure's value, one needs to think about a variety of factors. Most folks think of fertilizer nutrients as manure’s primary value or MVP, but it takes more than one or two star players to make a great team. As such, manure wouldn't be as great as it is without other characteristics like the added organic matter that you get when applying manure, or the microbial community that is added to your field with that application.

University of Nebraska-Lincoln (UNL) has changed recommendations for crediting nitrogen following manure applications for field crops. New research has shown that most manures are similar changing the organic-nitrogen availability factors.

The prices of synthetic fertilizers have increased significantly over the last year leaving growers and even homeowners facing the decision of finding alternative sources of nutrients. One great option is the use of manure or compost from a local farm or from your own operation. The use of manure in gardening can loosen compacted soil, increase carbon in the soil, and reduce surface runoff and leaching all while providing nutrients that your plants need. While this option is great, it is important to be aware of the potential carry over of herbicides in manure from grazing animals.

As planting is critical for everything else that happens during the growing season, the dry conditions have led to a variety of questions this planting season regarding soil conditions, planting depth, irrigation and herbicides.

A review of the history of irrigation in the Great Plains region from a geographical, technical and political perspective, as well as how it has impacted water resources.

A research paper by University of Nebraska–Lincoln scientists points to an innovative irrigation approach that offers promise to decrease water use while increasing producer profitability.

In the Nebraska Panhandle, Gary Stone is raining down knowledge for local growers looking for a little help. Find out what he's been up to out west in this installment of Digging into Extension.

Nebraska Climatologist Al Dutcher reviews the latest CPC forecast, which predicts drought intensification through the entire 2022 growing season.

The main barriers to adoption of new technologies in irrigation include cost and ease of use. These scientific methods need to be cost-effective and feasible for farmers to adopt. Today, using soil water monitoring equipment provides the most effective method for farmers to make data-driven irrigation scheduling decisions to apply the minimal amount of water while achieving optimal yields. However, the costs in labor and equipment limit their use. So, research continues to focus on developing lower-cost methods to schedule irrigation that results in putting on just the right amount of water. Since producers do not have time to do detailed work with large amounts of data often generated using SIS methods, the automation of SIS methods would likely provide incentives to producers by saving their time and, simultaneously, reducing the irrigation applications and producing optimal crop yield.
