Have you ever wondered if the water you are drinking is safe? Who studies the impacts of contaminates on my health? These are questions commonly asked throughout the state especially when there are stories continually discussing contaminates in the water we drink.

The Testing Ag Performance Solutions (TAPS) program is excited to offer a new six-part series focused on water, nitrogen and “Effective Conservation Technologies and Management Practices for Corn Production,” as the practicum is titled.

It’s definitely getting colder outside. Winter isn’t officially here yet, but it is on its way. This is the time of the year where we give up on plants, but there are some things to consider prior to winter to ensure their survival. Winter Care of Turf

A recent article by Dr. Steve Evett and others traces the history of irrigation in the Great Plains region from a geographical, technical, and political perspective as well as how it has impacted the water resources

In a growing season with high fertilizer prices like the upcoming 2022, varying the amount of N within the field could result in cost savings and yield increase, boosting your overall field profit.

Both plastic and copper pipes can freeze, and frozen water pipes affect folks who live in both cold and warmer climates. By conducting routine preventative maintenance, one can greatly reduce the risk of potentially expensive damage that frozen water pipes can cause.

With the recent increase in fertilizer prices, it is more important than ever to use the right amount of fertilizer to maximize the economic returns. Applying too little or too much fertilizer can result in substantial economic loss.

In spring 2021, many gardeners and landscape managers in eastern Nebraska had severe plant damage to boxwood shrubs. In many cases, entire plants were dead. In others, all branches above the protecting snow line were brown, dried and dead. Although boxwood was not the only type of plant showing damage in spring 2021, why was the damage so widespread on this species?

Does nitrogen becoming nitrate mean we are going to lose it? No, it takes rainfall or snowmelt in the spring that will cause a leaching event, but it does increase the risk of loss. Certainly, there is a balance between making sure we get our manure applied before the soil freezes and applying too early, but hopefully the information above illustrates a bit behind the science of the 50°F and cooling recommendation.

Fertility is critical to a good crop, so we know not to ignore our crop fertility needs, but we don’t always think about ways we may be able to trim costs by better utilizing local nutrients. Manure has many benefits, including some related to soil health, but perhaps the most recognized benefit is that manure contains the nutrients our crops need. Manure isn’t always an inexpensive product, but it contains multiple nutrients that are highly valued when planning your fertility program.

We are getting closer to fall which is a great time to work on improving your lawn. Late September and early October are great for spraying lawn weeds. When dealing with pests in your lawn, be sure to use pesticides correctly for the best success and for the least amount of damage to the environment.

Scheduling the last few irrigations of the season deserves more of your management time than earlier irrigations because one must not only focus on keeping the crop wet enough to produce optimal yields, but also on using up enough of the stored soil water to lower the level to 40% of plant available water in the top four feet. This level will give about 2.4 inches of water storage room in sandy soils and about 5.5 inches in silt loam soils. Unfortunately, many irrigators leave the soil fairly wet with little to no storage room according to a recent study.

Soil quality has been traditionally described in terms of chemical and physical properties; however, soil organisms play an important role in soil health. Some studies suggest that using manure as soil amendment could result in increased microbial biomass, which results in higher soil bacteria, fungi and higher microbial activity. Soil microbial activity is crucial for nutrient cycling, aggregate stability, fertility, and other soil characteristics leading to better crop productivity.

Plant roots grow in soil pore spaces. Pore spaces are also where oxygen is found. Just as plant roots cannot grow without water, they cannot grow without oxygen. Soil pore space is important to plant growth and efficient water use. Soils with good structure have adequate pore space making them well drained while still having good water and nutrient holding capacity. Ideal soils have 50 percent soil particles and 50 percent pore space. An important aspect of good soil structure is soil aggregation.
