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.

Soil Management for Water Conservation

Improved water infiltration, less runoff and reduced evaporative losses in no-till systems can save from 5 to 12 inches per year, making more water available for crop production. The tilled grain sorghum on the right yielded only 61 bu/A in a dry year while the no-till on the left yielded about 121 bu/A.

Papio-Missouri River NRD 2018 Groundwater Management Plan

The Papio-Missouri River Natural Resources District (P-MRNRD) 2018 Groundwater Management Plan incorporates and responds to new data and information about groundwater quantity and quality throughout the District.  The new plan incorporates data from studies, as well as regulation changes including:

Manure Applications Prior to Planting

Spring manure applications may provide environmental and crop production advantages compared to fall manure applications. These benefits include reduced nitrogen leaching, increased crop yields, and higher phosphorus and potassium nutrient soil storage.

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.

Precision Manure Application on Display at Manure Expo

Precision manure application is an important trend in managing animal manures.
While the North American Manure Expo may not reach bucket level status for your vacation plans, for anyone replacing or upgrading equipment for managing manure, it is the place to be. One emerging theme common at this year’s Manure Expo was “Precision Manure”. This article will share a few observations around my conversations with vendors and manure applicators on “Precision Manure”.

No-till, Cover Crops, And Planned Grazing Systems Workshop to be held in Norfolk February 12th

If you are interested in learning more about Soil Health, Cover Crops and Nitrogen Management consider attending the No-till cover crops grazing workshop held by the Bazile Groundwater Management Area, Lower Elkhorn Natural Resource District and the NRCS in Norfolk at the Lifelong Learning Center. The workshop will run from 9:00 a.m. to 3:30 p.m. with lunch provided by the Bazile Groundwater Area NRDs.

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.

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.

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.

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.
