Crop Management

Crop management hinges on the availability of water. For example, optimal plant populations will vary depending on the quantity of water available during the growing season.

Nebraska Mesonet Launches Improved, Real-time Weather Data

The Nebraska Mesonet, a critical tool for weather monitoring and data collection across the state, has launched a redesigned, user-friendly website offering real-time weather data. The upgrade comes as the mesonet is growing its network of weather monitoring stations across Nebraska to offer more accurate data.

DAWN Dashboard: A Decision Support Tool for the Corn Belt

Our Nebraska Digital Ag Survey indicated that digital dashboards have been adopted by three out of 10 farmers. Digital dashboards are considered decision support tools that can guide farmers in the decision-making process in their operations with the goal of increasing efficiency, productivity and sustainability of their farms. Data-driven decisions are a key goal for digital agriculture. In this article, we are highlighting the Dashboard for Agricultural Water and Nutrient Management (DAWN), developed by a team of universities as part of a USDA NIFA grant.

Registration open for Nebraska Master Irrigator Design Summits

We are excited to launch Master Irrigator in Nebraska and would like your help to build it! Master Irrigator is a producer-directed comprehensive educational series focused on taking your irrigated acres to the next level. We are hosting a series of Design Summits bringing together farmers, industry, extension, and policy partners. We'll preview and discuss across four key themes:

Phenology

Simulating Crop Phenology by Gregory S. McMaster, from The Regional Institute, 4th International Crop  Science Congress, 2004. Simulating Crop Phenological Responses to Water by Gregory McMaster, John White, A. Weiss, P. Baenziger, Wallace Willhelm, J. Porter, P, Jamieson; USDA Agricultural Research Service; Jan. 2008.

Variety Selection & Tests

EC197, Using Winter Wheat Yield Data to Improve Variety Selection PDF only (224 KB; 8 pages) This extension circular describes a method for comparing and selecting various wheat varieties.

Cover Crops

Crops including grasses, legumes or forbs used for seasonal cover and other conservation purposes. SARE Publications 2007, Managing Cover Crops Profitably, 3rd Edition. Beltsville, MD: Sustainable Agriculture Network, 244 pgs. $19 for book; PDF version available.

Crop Water Use

For more in-depth coverage of Crop Water Use issues, ETgages and Water Sensors, see Agricultural Irrigation.

Irrigation Scheduling

G1579, Using Modified Atmometers (ETgage) for Irrigation Management Describes the atmometer (evapotranspiration gage) and explains how it can be used for irrigation scheduling. Examples are provided to show how information collected with an atmometer can be used to estimate crop water use for corn and soybean. PDF version (975 KB; 4 pages)

Manure and Mulch are Teaming Up

Cedar trees are spreading into grasslands and reducing forages that support cattle grazing. The Nebraska Forest Service is promoting management practices to keep the trees from spreading outside of their usual habitat and into grasslands and areas along the banks of rivers and streams (called ‘riparian forests’). So what do cedar trees have to do with manure? Since 2015, two resourceful farmers have generously given up a few acres of their fields for UNL researchers to test various applications of mulch alone or co-mingled with cattle or swine manure.

Disposal of Flood Soaked Grains and Forages

Flood-soaked grain or hay is almost certain to be contaminated, making it unfit for use as food or feed.  This summary describes regulatory considerations and recommended actions for management of agricultural grains and forages deemed unusable for food or feed following flooding.

Crop management hinges on the availability of water. For example, optimal plant populations will vary depending on the quantity of water available during the growing season.
