Abstract

Compost humic acids are known to exert significant bioactive effects on soil organisms including plants. Three humic acids isolated from a green compost (GC-HA), a mixed compost (MC-HA), and a coffee compost (CC-HA) were tested at concentrations of 10, 50, and 200 mg L−1 on the germination and early growth of four switchgrass populations, Shawnee, Alamo, Shelter, and Dacotah. Experiments were performed in a climatic chamber under controlled conditions. An increase of germination percentage and a stimulation of primary root and shoot growth were observed as a function of the population, the plant part examined, and the HA type and dose applied.
