Leaf N-Fast


Leaf N-Fast is a nitrogen liquid fertilizer. Ureic nitrogen is readily absorbed by plants. Nitrogen plays an essential role in protein synthesis and in the enzymatic activities of the plant. Magnesium complexed with LS has a fundamental role in photosynthesis and in the production of glucides and lipids. Sulphur, together with nitrogen, favours the synthesis of sulphurated amino acids.


  • ureic nitrogen to guarantee an efficient and rapid absorption
  • balanced ratio among sulphur, magnesium and nitrogen to support the whole crop cycle
  • magnesium complexed with LS to support photosynthesis
  • N/S ratio developed to enhance late intakes and to improve protein synthesis
  • fertilizer unities 4 times more effective if administered by foliar application
