Crop Management

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.

Northeast Nebraska farmers and agricultural professionals will learn about tools they can implement to mitigate nitrogen loss at the 2022 Bazile Groundwater Management Demonstration Field Day. Hosts for the day include Lewis and Clark NRD, Lower Elkhorn NRD, Lower Niobrara NRD and Upper Elkhorn NRD and local Nebraska Extension Water and Integrating Cropping Systems extension educators with funding provided from the Nebraska Environmental Trust. Speakers will address important tools that can be used to mitigate nitrogen loss. The BGMA Demo Field Day is scheduled for Thursday June 30, 2022 southeast of Creighton, Nebraska (From Hwy 59 and Hwy 14 Junction, go three miles south on Hwy 14, then one mile west on 869 Rd and a ½ mile south on 523 Ave.). The field day will start with registration at 1 p.m. with the educational programing starting at 1:30 p.m. and ends at 7 p.m.

At the end of the season, a nitrate test can help determine whether the crop was under-, adequately or over-fertilized with nitrogen, resulting in the potential to significantly reduce input costs.

With the two consecutive dry seasons in 2021 and 2022, there is likely a considerable amount of unused nitrogen left in the soil, which could be used for the 2023 crop. With the higher fertilizer prices, such fertility adjustments for next crop can be profitable as well as environment friendly. So, it is recommended to test your soil and account for all sources of nutrients for the next crop.

Fall frosts have ended the life cycle of many annual plants. In some cases, below-freezing temperatures have reduced insect numbers and finally ended the harvest challenges of extended green soybean stems and corn plants. Despite the cold nighttime temperatures, many crops are still growing. So, the question arises: “How much irrigation should be applied in late fall for perennial and winter annual crops like alfalfa, wheat, rye and triticale?”

Center pivots comprise three main components: the pump, power unit and pivot. Traditionally on leased cropland, the landowner owns the pump and pivot. Depending on the area of Nebraska and available energy sources, the power unit may be owned by the landowner or tenant. Ownership of the pump and pivot by the landowner creates greater flexibility for the management of the land when terminating the tenant or selling the property.

Some crop growers have always removed crop residue for animal feed and bedding. Crop residue removal should be done in such a way that it benefits the grower without negatively impacting the health and productivity of the soil as well as the environment.

In this two-day course, NU experts will be discussing the latest research on soil fertility, precision ag for nitrogen management, cover crop effects on soil, soil carbon sequestration and more.
