MAN-8 contains manganese which is an essential micro-nutrient. MAN-8 combines manganese and sulfer with Biofeed’s exclusive Amino-Carbon Technology® ACT to promote plant growth. Many processes are dependent on manganese, including chloroplast formation, photosynthesis, nitrogen metabolism and synthesis of some enzymes.

Manganese (Mn) is required by plants in the second greater quantity compared to iron. Like any other element, it can have a limiting factor on plant growth if it is deficient or toxic in plant tissue.


  • Promotes dark green leaf color in palm trees and other plants.
  • Supports the photosynthetic pathway in all plants
  • Improves plant respiration of atmospheric carbon dioxide
  • Promotes root cellular elongation
  • Activates resistance to root pathogens
  • Improves nitrogen metabolism within the plant
  • Promotes stress tolerance
  • Easy to use liquid fertilizer formula
  • Organically complexed – readily available
  • Use year-round


Sulfur (S)…………………………………4.0%
Manganese (Mn)……………………..8.0%

Derived from Manganese Sulfate.

MAN-8 also contains Biofeed’s exclusive Amino-Carbon Technology® ACT to provide natural organic acids, surfactants, enzymes, amino acids, bio-stimulants, and buffers.



MAN-8 is highly concentrated for pro-level performance and value. Mix with water to ensure adequate coverage. Jar test for compatibility prior to final tank mixing with other products.
