Spirodela punctata has a taxonomic position intermediate between Spirodela (. The shade form. Under optimal conditions, a duckweed farm can produce 10 to 30 tons of dried duckweed per hectare per year. Using NT-MAX Biological Digester Treatment on a regular basis clears muck away and restricts sludge and bio-waste buildup. The prophyllum of Landoltia punctata is much smaller. Lemna is much larger than, wolffia. It has been estimated that 10 acres of duckweeds could theoretically supply 60 percent of the nutritional needs of 100 dairy cows, the manure of which could be recycled to provide fertilizer for the thriving duckweeds.
