N-Boost vs Gibb

The N-Boost® System is designed to double the pasture response to 40kg/ha of urea with regular applications.

Gibberellic acid is a plant growth regulator for rapid growth. For optimum results, Donaghys recommends GibbSTART MAX should be used strategically twice per year (early spring and late autumn).

Gibberellic acid can cause* a lag in re-growth along with:

  • Grass and Brassicas seeding faster
  • Suppression and underdevelopment of roots
  • Reduced tillering – less shoots in pasture
  • More stem growth and less foliage
  • Underdeveloped nodules on clover roots causing reduced nitrogen fixation
