Plant breeding research that focuses on modifying big bluestem composition to minimize recalcitrance to bioconversion and increasing biomass yields is imperative. Various constraints and potential applications of big bluestem as an energy crop are analyzed in the final section of this paper. Estimated ethanol yield of big bluestem is about 1886 L/ha, which is comparable to previously reported herbaceous biomasses. Conversion includes discussion of the conversion of big bluestem biomass to bio-ethanol and bio-oil. Biology includes distribution and adaptation of big bluestem, ecotypes and varieties currently studied, production management, and disease and pest control.
The objective of this paper is to review big bluestem׳s potential as a bioenergy crop with respect to both biology and conversion. Ranchers adopted the species as a forage crop long ago, but its high cellulosic content and low agricultural input requirements recently have made big bluestem a promising feedstock for ethanol production and bio-oil.

Once the bluestem grass has becomeĭormant, you must wait until next year however, if it is still green, autumn is the best time to Since the bluestem stands above the other grasses, it isĮasy to target them while protecting the desired lawn grass. Some of these (like the glyphosate mentioned as an example)Ĭannot be taken up from the roots, so surrounding plants are not injured and there is no residue The reason this works is that some herbicides are absorbed by green tissues of the plant and The bluestem may need to be treated more than once. Follow the directions that come with the herbicide you choose to maximize the effect. Disposable gloves may be used and then discarded after (without holes) plastic or rubber gloves. If you don't need to treat a large area or don't want to purchase the special applicator (or can'tįind one), you can use a sponge and a small container of diluted herbicide. Transferred to the grass blades as you wipe the sponge across the grass. The sponge becomes moistened by the herbicide that is then These often have a tube containing the herbicide with a sponge or The taller bluestem grass without harming the lawn grass. By brushing it on (diluted to the label recommended concentration), you can target Spraying will probably kill a spot of the desired lawn grass around the It may be applied to the leaves of the bluestem by spraying or byīrushing (painting) it on. Choose an herbicide labeled to kill grass. Introduced Bluestem Grasses - Management on Native Lands Topics: Crops & Produce Pastures & Forage Plants & Crops Overview To combat Kleberg and King Ranch bluestems, land managers have tried burning, disking, mowing, plowing, and combinations of these tactics. Grass growing in grass you don't want to kill. If you choose to use herbicides, it is important to be very careful because you are trying to kill
(a lot of work) or spot applications of herbicide. However, quicker ways to remove it include digging Grass should eventually overwhelm the bluestem. If it is mowed frequently to a short height and the surrounding lawn is in good health, the lawn Dreamstime is the worlds largest stock photography community. However, I can see where it can be a problem. Use them in commercial designs under lifetime, perpetual & worldwide rights. Ornamental (un-mowed) grass in landscapes in New Mexico because it is so well adapted andĪttractive. We are recommending Little Bluestem as an It is interesting that you have a problem with bluestem. Chameleon Little Bluestem Grass (Schizachyrium scoparium) - 1 Gallon Pot With a glamorous and dazzling and succession of color changes throughout the year that will light up the landscape, ‘Chameleon’ Little Bluestem is a superstar of a low-maintenance and easy-to-grow North American native grass anyone can grow. How can I get rid of it without killing my good grass? I cut it down, and the next day it is up I have a lot of bluestem grass in my yard this year, more than ever.
