Crabgrass is an annual, warm-season grass. Crabgrass produces best on well-drained soils such as sands, sandy loam, loamy fine sand, loam, and silt loam. Crabgrass grows best at about 80 to 100 degrees Fahrenheit. For best yields, the tillage should be moderately deep, resulting in a relatively firm soil, and be completed before spring seed germination. Crabgrass to nitrogen fertilization very well.
Crabgrass is relatively easy to produce from planned volunteer stands: the manager simply must control grazing or conservation harvests to allow adequate seed drop the prior season or two and then either apply the proper shallow dormant-season tillage or tread the seed in with stock under nontillage approaches.
Crabgrass is used for all major classes of farm stock, including beef cattle, dairy cattle, sheep, and horses. Crabgrass can be produced as a pure single warm-season forage; a mixture component in bermudagrass, millet, or sorghum pasture; and a mixture component with a summer forage legume, such as cowpeas, soybeans, mungbeans, or annual lespedezas.
Recommended planting rate is 3-5 PLS lbs per acre.
