Osage Orange: Identification and Management

Osage orange [Maclura pomifera (RAF.) C. Schneider] is a native tree species also known as bois d'arc, hedge apple, bodark, horse apple and bowwood. Its natural range was limited primarily to the Red...

A Global Classroom

Noble Research Institute Research Scientist Rao Uppalapati, Ph.D., has created a biofuels lesson plan for the University of Oklahoma's K20 Center for Educational and Community Renewal that will be available worldwide in June.

Fantastic Forages

Noble Research Institute associate professors Rujin Chen and Kiran Mysore use mutant varieties of Medicago truncatula to discover genes impacting plant functions like forage quality, nitrogen fixation and plant architecture.

Pasture Weed Management and Drought

Pasture weed management always presents a challenge. There are dynamic, complex interactions between desirable forages, grazing animals, encroaching weeds, soil types, nutrient levels, climate and...

Winter Pasture Options Following Summer Drought

The drought conditions have left forage resources for this year's fall and winter in short supply for most producers. Over the last couple of months, calves have been early weaned and cattle herds have been culled heavily, relocated to pasture or completely dispersed.

Determining the Value of Weathered Hay

The drought of 2011 is set to go down in the record books as one of the most severe in history. Most livestock producers in the Southern Great Plains have not been able to put up enough hay to meet their requirements in a normal growing season, let alone during a drought when they will have to start feeding hay earlier in the year.

Does Lime Pay on Winter Pasture?

Let's say you look at the results from your soil sample and see there is a recommendation for lime. You check around and discover this is going to cost $40-$50 per acre. A normal person would question whether the value received from liming is worth the cost.

Drought-induced Cattle Poisoning

Cattle producers should be on watch for two types of poisoning during drought. The potential for nitrate and prussic acid poisoning of cattle is most often associated with dry periods; therefore, livestock owners should take precautions, including forage testing. Often the first indication of a problem is one or more dead animals.

Fish Population Renovation During Drought

If your pond is low, this might be the perfect time to renovate poor or marginal largemouth bass, bluegill and channel catfish populations or eliminate undesirable fish such as bullheads, common carp, warmouth and green sunfish. If your pond is dry, you will need to make plans to deepen it before stocking fish next spring when, hopefully, it's full again.

Is Herd Liquidation Inevitable?

With triple-digit temperatures and very little rain, the livestock industry is feeling the effects of drought. The United States Department of Agriculture has rated 90 percent of pasture conditions in the region as very poor. To make matters worse, most livestock water sources are drying up or have reached a point where water quality is a major concern.
