Weed of the Week: Grassbur (field sandbur, sandbur, etc.)

Grassbur is a grass weed that is very troublesome in pastures and hay meadows throughout Texas. Most grassburs are easily recognized in the mature stage of growth when the “bur” seed heads become apparent. The bur itself is actually a “capsule” that usually contains from 1 to 3 seeds. We tend to think of the grassbur species as a warm season annual plant. However, many grassburs are classified as perennials because they can survive from one year to the next. The presence of grassburs can be an indication… Read More →

Sprayer Maintenance

Now’s a good time to start your sprayer maintenance before the active spraying season begins. Tuning up your sprayer can better prepare you for accurate and effective herbicide applications. Any sprayer, old or new will perform better if you check it over before heading into the field. The most common causes of inconsistent spray patterns are nozzle tips with different fan angles on the boom, uneven boom heights and clogged nozzles. Follow manufacturer recommendations to select nozzles for the best coverage. Make sure nozzles are clear of debris… Read More →

Does a New Year Mean a New Pasture/Hay Meadow?

It’s always best to initiate the planning process the year prior to actual planting. So start planning in 2019 to plant in 2020. Instead of planning in 2019 to plant in 2019. Evaluate the farm’s forage needs. Consider how the forage will be used (grazing vs. hay), what species are better adapted to your area (season, soil type, rainfall) and what resources (equipment, money, and time) are available. Reestablishment should be considered when less than 40% of the desirable species exist. For exclusive hay production: Take visual appraisal… Read More →

Hay Meadow’s Friend or Foe?

Annual Ryegrass…a cool season annual forage often utilized by livestock producers for winter grazing. However, it’s often deemed an enemy of many a hay producer in East Texas. Volunteer annual ryegrass can be common in hay meadows. Winter rainfalls can promote seed germination and seeds can survive for multiple years in our soils. Later maturity of annual ryegrass can delay or prevent our warm season perennial forages (i.e. bermudagrass or bahiagrass) from breaking dormancy in April/May therefore delaying our initial hay cutting.   So how do we manage… Read More →

Eastern Texas Forage Calendar

Need a last minute Christmas gift or an extra stocking stuffer… Landowners interested in managing forage production for grazing and/or hay can use this calendar for management suggestions specific to each month and to record the dates of the management tasks performed. Keeping a record of management activities by date can help you document your management strategies for your pastures each year. To order a copy visit: http://agrilifebookstore.org                                            

Winter Weeds: Do they matter?

As forage producers, we focus most of our energy on our warm season perennial pastures and hay meadows (bermudagrass, bahiagrass, etc.). That means most of our weed control efforts are also focused on warm season weeds (such as carolina horsenettle, blackberry, etc). Unfortunately, cool season weeds can be just as detrimental to our warm season perennial forages.   Annual ryegrass…a cool season annual forage often utilized by livestock producers for winter grazing. However, it’s often deemed an enemy of many a hay producer in East Texas. Later maturity… Read More →

Fertilization of Winter Pasture

Fertilization of winter pasture should be based on a soil test to maximize forage production and prevent applying more fertilizer than is needed. Nitrogen fertilization of small grain and small grain-ryegrass mixtures can be split in 2 to 4 equal applications during the growing season. Two applications are often sufficient in Central Texas with lower rainfall and heavier textured soils. Three or four applications are required on the sandy soils in East Texas because of low nutrient holding capacity and high rainfall. Phosphorus and potassium can be applied… Read More →

Multiple Agriculture CEU Courses Offered Online

The Texas A&M AgriLife Extension Service Ecosystem and Management Unit is offering Texas Department of Agriculture (TDA) continuing education units (CEUs) for private applicators online in November. Private applicators need 15 CEUs every 5 years, and a maximum of 10 can be from recorded online courses and/or correspondence courses. Five CEUs must come from a live class or webinar in order to meet the TDA requirements to recertify. Of the 15 CEUs, a minimum of 2 must be laws and regulations, and 2 must be integrated pest management… Read More →
