| Abstract/Contents: | "Nutrient buildup in pastures from repeated animal manure application may increase soil P and contribute to eutrophication and water quality deterioration. Options to remove excess nutrients in pastures have been limited in the past. The objective of this 2-yr study was to evaluate the potential of using Red River crabgrass [Digitaria ciliaris (Retz). Koel.] to remove excess soil P from nutrient-enriched soils. Red River crabgrass was planted in boxes containing Dennis (fine, mixed, active, thermic Aquic Argiudolls), Richfield (fine, smectitic, mesic Aridic Argiustolls), and Kirkland (fine, mixed, superactive, thermic Udertic Paleustolls) soils with four different soil test P levels in 2010 and 2011. The Mehlich-3 phosphorus (M3P) at the beginning of this experiment ranged from 82.3 to 723 mg kg-1 for the Dennis soil, from 91.5 to 836 mg kg-1 for the Kirkland soil, and from 57.5 to 585 mg kg-1 for the Richfield soil. The overall average biomass yield of crabgrass was 12.2 Mg ha-1 in 2010 and 10.7 Mg ha-1 in 2011. The harvested biomass contained an average of 4.5 g P kg-1 in 2010 and 3.7 g P kg-1 in 2011. Therefore, the crabgrass removed an average of 49.1 kg P ha-1 per year. In addition, the concentration of P in the crabgrass and P removed from the soil increased as M3P increased. Crabgrass can serve as good quality hay and as an effective plant for removing excess P from soils." |
