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
