Liquid Calcium: A substitute for what?

Liquid Calcium:  A substitute for what? The transportation and application costs associated with limestone applications often exceeds the cost of the limestone by 10-30 times.  When soil test recommendations call for three, four or even five tons per acre, the end cost can sometimes exceed $300 per acre.  Increasingly producers are looking toward non-traditional approaches to battle low soil pH.  Over the past several years, online ad posting have stressed the liquid calcium formulation marketed by company X or Y is many times more available than the calcium… Read More →

Grasshoppers!

There are about 150 species of grasshoppers in the state of Texas, but 90% of the damage to crops, gardens, trees, and pastures is caused by just 5 species. Grasshoppers deposit their eggs 1/2 to 2 inches below the soil surface in pod-like structures. Each egg pod consists of 20 to 120 eggs. Egg pods are very resistant to cold and can easily survive the winter if the soil is not disturbed. Grasshoppers deposit eggs in fallow fields, ditches, fencerows, and weedy areas, as well as in crop… Read More →

Herbicide Applications During Dry, Hot Months

Invasive brush can decrease forage productivity for livestock or decrease brush diversity valuable for wildlife habitat.  Most ranchers find themselves constantly considering options for brush management, weighing not only the cost and effectiveness, but also when they can find the time to complete the treatments.   As temperatures continue to climb across the state and the chances of rainfall seem to be weakening, it’s important to consider the effect this will have on any herbicide applications. Treating weeds or brush with a leaf spray application when temperatures are as… Read More →

Nitrogen Fertilizer Sources

Nitrogen is an essential plant nutrient. Plants readily take up and use two forms of soil nitrogen, ammonium (NH4+) and nitrate (NO3-). Other forms of nitrogen must be converted to one of these compounds before plants can utilize them directly for plant growth. Sources of Nitrogen: Plants such as legumes “make their own” nitrogen. A symbiotic (positive for both parties) relationship between a legume and rhizobium bacteria develops and the bacteria “fix” nitrogen out of the atmosphere and convert the nitrogen gas into forms that can be used… Read More →

Bermudagrass Stem Maggot

The bermudagrass stem maggot (Atherigona reversura), a pest of bermudagrass forage in Texas has been reported in multiple counties since 2012. The bermudagrass stem maggot is native to south Asia (from Japan westward to Pakistan) and was first reported in the United States in Georgia in 2010. This pest only infests bermudagrass and stargrass (Cynodon spp.). The fly (yellow with black head) lays its eggs within the stem of the bermudagrass plant. Once the egg hatches the larva, or maggot, (white with black head, 1/8” – 3/16” long)… Read More →

Potassium is for Persistence

We rely heavily on our bermudagrass pastures and hay meadows during the summer in some parts of Texas. Often times we are disappointed with production, see a thinning of our stand and/or see disease like symptoms. This is often times referred to as “Bermudagrass Decline.” We quickly blame weather. Granted weather can have an impact on each of those issues. However, there is often a deeper problem that we need to access. Primary Causes: Low Potassium (K) Fertility: A deficiency in K will result in poor stress tolerance,… Read More →

Weed of the Week: Wild Carrot

Wild Carrot (Daucus carota): Wild Carrot, also known as queen anne’s lace, is a biennial broadleaf plant. Wild carrot forms a rosette of leaves the first year, then flowers, produces seed, and dies the second year. It forms a deep, whitish taproot that has a distinctive carrot odor. Mature plants reach 2 to 4 feet tall and have erect stems and few branches. Leaves divide several times, forming many long, narrow segments. Leaves on the lower part of the plant have stalks. Those on the upper part of… Read More →

Warm Season Annual Forages

Believe it or not, we can actually grow some forages other than Bermudagrass and Bahiagrass in Texas! Warm season perennial grasses, such as bermudagrass and bahiagrass, make great foundations for pastures in Texas. However, there are additional forages that can be utilized for pasture or hay production in Texas. As always, when selecting forage species make sure to match species and variety to your location (soil type and average rainfall) as well as to your production system goals. For assistance in selecting a forage species and/or variety contact… Read More →

Rained on Hay

After mowing, poor weather and handling conditions can lower hay quality. Rain can cause leaf loss and can leach nutrients from plants during curing. Rain can leach out nutrients and increase dry matter loss from respiration, which is the process by which a plant uses oxygen. Nutrient losses depend on the amount, duration and timing of the rain in relation to cutting time. Purdue University has conducted research on the amount of total digestible nutrients (TDN) and field dry matter lost from hay after a rain. The study… Read More →

Weed of the Week: Horseweed

Horseweed (Conyza canadensis): Often times called: mare’s tail. Warm season erect annual weed. Often found in cultivated areas, pastures, road sides and waste sites. First leaves are in a rosette. Stem with frequent alternate and sessile leaves. Horseweed generally bolts in April/May, flowers in July and sets and disperse seed from August to October. Control of horseweed is more effective when plants are in the rosette stage or less than 2 inches tall.             Select Herbicide Options: Weedmaster 2, 4-D GrazonNext HL Duracor… Read More →
