Biomass, Nitrogen Uptake and Content of Wolffia arrhiza Depends on Strength of Swine Lagoon Water

Abstract: Studies focusing on manipulation of growth conditions for duckweed Wolffia arrhiza to promote biomass for crop nutrient supply, are scarce. The effects of swine lagoon water (SLW) concentration and its replenishment and harvest regimes on selected properties of W. arrhiza were investigated. Dry matter and average growth rate of W. arrhiza were not affected by SLW replenishment periods, whereas the properties decreased with increasing concentration of SLW. The carbon and carbon/nitrogen content increased as the… Show more

“…[13,14]. Hence, duckweed species can be effectively used to remediate a variety of nutrient-rich wastewaters, including diluted livestock farm manure [9,14,15], aquaculture wastewater [16] or dairy processing wastewater [17,18]. Notably, duckweed biomass can be used to produce biofuel (e.g., ethanol and methane) [19].…”
