DESCRIPTION:Speakers: Natasha Manyenga (BETA Technological Centre-Universi
 ty of Vic-Central University of Catalunya (BETA- UVIC- UCC))\nIntensive sw
 ine farming generates nutrient-rich wastewater that\, if mismanaged\, pose
 s environmental risks but also offers opportunities for resource recovery.
  Duckweed\, noted for its rapid growth and high nutrient-uptake capacity\,
  offers a promising solution for wastewater treatment and holds untapped p
 otential for agricultural valorisation. This study investigated duckweed c
 ultivated on both swine wastewater and mineral fertilizer to produce a nut
 rient-rich biomass for application as an organic amendment\, thereby enhan
 cing sustainable food production.\nAgronomic evaluations were conducted to
  assess the potential of duckweed as an organic amendment in comparison to
  mineral fertilizer and raw manure. Duckweed biomass\, both dried and fres
 h\, was tested in a 52-day pot experiment with spinach (Spinacia oleracea)
  and lettuce (Lactuca sativa). Additionally\, wheat (Triticum aestivum) wa
 s grown for 168 days under laboratory conditions. The findings indicate th
 at duckweed-based amendments\, when combined with raw manure\, enhanced th
 e growth and biomass accumulation of spinach\, lettuce and wheat\, outperf
 orming the mineral fertilizer treatment. The fertilizing potential of the 
 produced biomass\, in both dried and fresh forms\, was demonstrated to be 
 comparable to the use of raw manure and other inorganic fertilizers.\nThe 
 integrated use of duckweed with raw manure further enhances soil nutrient 
 cycling through synergistic effects on mineralization\, reinforcing the ap
 proach of combining organic nutrient sources to optimize crop performance 
 and soil health. Duckweed-based amendments reduce nutrient losses\, slowly
  releasing nutrients\, and enabling wastewater bioremediation and producti
 on of nutrient-rich biomass that supports sustainable crop production and 
 soil regeneration.\n\nhttps://indico.unina.it/event/117/contributions/2945
