Agricultural Production Crop Production

Crop Production

The production of crops is the heart of Nebraska's economy. Water is essential to all plant growth. Thus Nebraska's economy relies on a plentiful supply of water to produce crops – in both rainfed and irrigated environments. Several factors involved with producing crops interact with either water supply or water quality issues – or both.

Mullen and Cameron Peak Wildfires and Their Potential Effect on Nebraska Ag

The Upper North Platte River watershed headwaters is located in north-central Colorado, close to Walden, CO. The Sierra Madre mountain range is on the west side of the headwaters and the Snowy Range mountain range is on the east side. Snowmelt from both of these mountain ranges together contribute approximately 75 percent of the water flow in the North Platte River. The fires’ effect on water supplies in the coming years will depend on the amount of snow fall and snowpack received in the watershed during the winter and early spring. There may be slightly higher incidences of sediment runoff in isolated areas where there is little or no ground cover due to the fire.

Planning 2021 Fertilizer-N Application Following a Dry 2020

Anticipated high residual soil nitrate-N levels in NE rainfed crops of dry 2020 can be credited to reduce N rates for 2021
Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?

The connection between soil organic matter and soil water

Soil Aggregate
One benefit of increasing soil organic matter is to store more water in your soil. Why does this happen? Because soil organic matter creates pores in a range of sizes. Exactly how much more water is stored due to soil organic matter will depend on soil texture, though. Animal manures are one option for increasing soil organic matter and soil health.

Proposed Changes to Nebraska Recommendations for Manure Nitrogen Credit

 This article introduces University of Nebraska-Lincoln (UNL) proposed changes in recommendations for crediting manure nitrogen in a crop’s fertility program.
Managing manure for economic and environmental benefit is based, in part, upon our ability to efficiently recycle manure nitrogen (N) between animals and crops. This article introduces University of Nebraska-Lincoln (UNL) proposed changes in recommendations for crediting manure nitrogen in a crop’s fertility program.

Manure Nitrogen Use for Increased Profit and Environmental Protection

For many years, the University has used a recommended equivalence of 47% available over the course of 3 years for feedlot manure, 37% for compost, and 52% available for poultry manure with litter. Recent research shows that these numbers may be a little low, but they are intentionally conservative so as not to limit yield due to nitrogen deficiency.
