Reduce atmospheric carbon dioxide use Carbon Buster™ grasses and legumes
Carbon BusterTM Hughes stylo mix is a robust, semi-erect to erect, perennial legume, usually growing to less than 1 m. It prefers well drained, open textured soils from sands to light clays. While it can grow in strongly acid to alkaline soils (pH from 4.0-8.0), it is only moderately tolerant of high aluminium (Al) and manganese (Mn), and not of high salinity. It is not as drought-hardy as ‘Seca’ stylo, growing best in areas with an average annual rainfall over 1000 mm.
APPLICATION It can be used for grazing or cut-and-carry in long and short-term pastures, or for ground cover (erosion control) in orchards, green manure and hay.
- Adapted to acid infertile soils
- Low phosphorus (P) demand
- Moderately tolerant of aluminium (Al) and manganese (Mn)
- Easily established from seed
- Resistant to current strains of anthracnose
- Growth habit best suited to rotational grazing or well managed stock numbers and cut-and-carry
- Does not twine
- Leaf stays green into dry season
- Frost tender
Sowing rate in mixtures 2 to 3 kg per hectare
- Soils: Grows best on well-drained, open textured soils from sands to light clays. Adapted to a wide pH range (from 4.0 to 8.0) and is moderately tolerant of high Al and Mn but not high salinity. Will extract phosphorus (P) very efficiently from low P soils but still responds to applications of P as well a K, S, Ca, and Cu in soils with low levels of these nutrients.
- Moisture: Can persist in areas with annual rainfall as low as 700 mm but is best suited to >1,000 mm. Once established capable of surviving long dry periods. Tolerant of flooding and short term waterlogging.
- Grazing: Moderately palatable to livestock, and has value as standover feed in early dry season. Grazing (or cutting) of well-developed plants can kill the plant as there are fewer growing points close to the ground. Best to stimulate lower branching early by cutting or controlled grazing to 10-20 cm in the first few months. Grazing on a one week on and four weeks off rotation normally favours this legume.
- Fire: Plants are set back by fire and killed by hot fires, particularly if the soil is dry.
- Fertiliser: Carbon BusterTM Hughes stylo mix responds well to improved soil fertility, particularly P, but can grow on infertile soil. In deficient soils, 10-20 kg/ha P is recommended as well as other nutrients as indicated by a soil analysis.
- Companion species: Not usually grown with other legumes. Grasses include rhodes grass, Premier digit grass, Strickland fingergrass, NuCal™ guinea grass mix, panics, setaria and signal grass.
- Weed potential: Appears to pose little threat in most situations.
- Dry matter: Capable of producing up to 20 t/ha, depending on favourable growing conditions and soil fertility.
- Pest and Diseases: Anthracnose resistant
- Herbicide effects: Tolerant of 2,4-D; from about 6 weeks of age, at 1.65 kg a.e./ha. Also tolerant of 2,4-DB, acifluorfen and bentazone. Like most legumes, it is susceptible to metsulfuron-methyl.
- Toxicity: No record of adverse effects
- Inoculant: There is usually no need to inoculate seed of Carbon BusterTM stylo mix, but use of Group I commercial inoculant may improve nodulation.
