A resurging interest in cover crops raises a new set of practical questions from farmers looking to improve soil health.

So You Want To Grow Cover Crops: 3 Questions to Ask Before You Start

Cover crops can provide soil health benefits, but it is important to have a plan. Before growing cover crops, producers should consider goals, herbicide and pesticide use, and available resources.

Water resources serve agriculture, energy, society

Ben Franklin wrote, "When the well's dry, we know the worth of water." Unfortunately, the "well" is running dry in many parts of the world. Rivers are running dry prior to reaching the seas because we are over-allocating and overusing them.

Niche market opportunities emerge for rye

There are three emerging niche uses for rye of which farmers in the region should be aware.

Farm and Ranch Vehicle Compliance

Every day, farmers and ranchers load up their trucks and trailers with agricultural products and haul those materials to and from their farms and ranches. Every time they do, they could be subject to the tangled web of transportation regulations implemented and enforced by an alphabet soup of state and federal agencies.

Seed Drill Calibration

Getting the correct amount of seed planted with a grain drill requires calibrating the drill before planting begins. Jim Johnson, Noble Research Institute soils and crops consultant, demonstrates step-by-step how to perform this calibration and the calculations required to determine accurate seed output.

N-rich strips hold value for wheat producers

N-rich strips can help wheat producers determine whether or not their fields need additional nitrogen fertilizer, which helps them conserve resources.

Watch Out for These Weeds in Drought

With the drought-induced import of vast quantities of hay into Oklahoma and Texas from neighboring states and beyond, there is a risk that invasive weeds will be brought in with that hay.

Looking Ahead at 2012 Sprayer Needs

Timing is critical for effective weed control using herbicides. Although there aren't enough hours in the day for them to cover all the acres that need to be sprayed each spring and summer.

Techniques conserve water resources

Ways resource stewards can make more efficient use of water.

Goats and Weed Control

With costs on the rise, many landowners are seeking less expensive alternatives to mechanical or chemical weed control in pastures. One natural method to achieve this goal is to stock goats to consume unwanted brush and weeds.

Taking Agricultural Education to Iraq

In the summer of 2011, I was preparing to go to Iraq - not as a soldier, but as an agricultural consultant. More specifically, I was going to Erbil, in the Kurdish region of northern Iraq, to teach crop residue management for a week.

Control Thistles During Winter

When thistles bolt and begin to flower each spring, folks who want to control them call the Noble Research Institute. By the time they call, however, it is usually too late in the season. Once thistles become reproductive, they are much harder to control and may have already produced viable seed.

Maximizing the Efficacy of Glyphosate

In some areas of the U.S., we are seeing glyphosate-resistant weeds. One strategy to prevent herbicide-resistant weeds from developing is to get a good kill with all herbicides that are used.

Wheat alternatives expand winter pasture choices

The vast majority of the winter pasture in the Southern Great Plains is wheat. There are many reasons for this, including culture, the opportunity to harvest and sell grain, and government and insurance programs.

Grazing affects plant root growth

I've always kind of known that grazing management affects roots, but it was made crystal clear to me this past summer when I was introduced to some work published by F.J. Crider in 1955.

Healthy soil aids drought and flood management

Other than the lack or abundance of precipitation, the reason for droughts and floods is the soil's inability to effectively absorb and release water.

New testing methods measure soil organics

Traditional soil test methods have typically involved treating a soil sample with various acids and other reagents to extract a portion of the inorganic nutrients in the soil. This can hopefully be done with as few processes as possible to be fast and cheap, and fit the industrial model.

What Tools Are in Your Toolbox?

Smart phones are excellent examples of tools we can use to make our agricultural operations more efficient and productive. These tools, whether in one package or as separate units, allow the exchange of voice, text and picture information.
