Product Description:
Soil Fit is a granular bio-stimulant and soil amendment designed to enhance your regular fertilizer applications. With an 8-0-2 analysis, you’ll get a slow-releasing yet effective green-up, all while fortifying your soil with chelating humic, stress-reducing sea kelp and all-important protein hydrolysates, the building blocks of life.

Here’s a little more about what’s inside this stellar soil amendment:

  • HUMIC: Condensed organic material that improves soil structure and root growth, increases the soil's ability to hold water and nutrients, and creates a better living environment for microbes.
  • SEA KELP: Improves resistance to heat, cold, and drought stresses.
  • PROTEIN HYDROLYSATES: Provides proteins and amino acids (the building blocks of life) to optimize plant performance and improve recovery cycles.
  • CALCIUM (Ca): Binds organic and inorganic substances in the soil and promotes strong cell walls
  • Feather Meal, Blood Meal, Wheat Flour: Natural Slow-release Nitrogen from recycled refuse
