Black Soldier Fly (BSF) Frass:

  • Improved nutritional value in aquaponic systems when used as "frass tea".

  • Similarities in length, number of nodes, stem diameter, and chlorophyll between control and treatments when applied as a top dressing.

  • Increased production when partially replacing synthetic fertilizer.

  • Solid BSF frass compost as a one-time top dressing for sweet potato in aquaponics is at least equally suited as daily inorganic fertilisation, resulting in greener and healthier leaves.

  • Highest benefit-cost ratio for the use of solid frass compost compared to inorganic fertiliser, and frass compost tea.
