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.

Melting Snow is Stormwater Run Off

ice melt on concrete
When we think of stormwater runoff we often think of rain. Snow melt during winter can also become stormwater runoff and carry pollutants to surface water. During winter the ground is usually frozen and melting snow cannot infiltrate into soil as a light rainfall will do. Depending on the amount of snow, this can lead to increased runoff during winter.

Odors that are comparable to that of rotten eggs are not ideal in your home or coming from your drinking water faucet. Sulfate, which is a combination of sulfur and oxygen, are naturally occurring minerals. They are found in some soil and rock formations where groundwater is stored. Bacteria that feed on sulfur can produce hydrogen sulfide gas which is the primary offender when it comes to odor.

September Continues Warm, Dry Trend as Drought Worsens

Precipitation continued the trend of a general lack of moisture during the first month of fall. Our monthly statewide total came in at 27th driest and makes for the 12th driest three-month (July–September) period on record. At the start of October, nearly all of Nebraska is in a drought category, according to the U.S. Drought Monitor. Portions of the northeast and southwest are in exceptional drought (D4). Temperatures averaged above normal for September and quite a few new daily high temperature records were set, most in the triple digits. The October outlook doesn’t appear to have much relief in sight with a higher-than-average probability of the warmth and dryness to continue. Given the dryness, fire danger will be high particularly on windy days.

Yucca Control and Fall Irrigation

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?”

How To Adjust Rental Payments When Tenants Own the Center Pivot

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.

During our in-person events this summer, we had a lot of fun talking with kids of all ages about the diverse types of manure, how manure provides nutrients to growing crops, and how manure helps improve soil health and water quality. We hope that all the kids we talked to learned how much manure matters in Nebraska. We also asked our in-person participants to submit some of their own more artistic interpretations of how “Manure Matters in Nebraska” for a chance to win a fun prize.

Safe Winter Pesticide Storage

Store liquid and dry pesticides formulations correctly during winter.
As the growing season draws to an end and we put away our gardening equipment, it’s also important to store any remaining pesticide products properly to prevent contamination and maintain product effectiveness for next year. But even more important, being careless with pesticide storage is an open invitation to disaster, in the form of a pesticide poisoning or spill which could contamination ground or surface water.
