Soil Biology

SB NutriZorb

Key Facts

SB NutriZorb is a natural, hydrated Phillipsite-Chabazite mineral of volcanic origin, supplied in three grades to suit the application.

SB NutriZorb supports soil biology by providing a “protective matrix” and a source of nutrients, firms up soft surfaces and slowly releases nutrients to suit turf growth.

SB NutriZorb does not break down as easily as clinoptolite zeolite. 

 

Application

For new rootzones / growing media - Mix at a 0.5 kg to 1 kg per 1 tonne of rootzone.

To absorb water in existing rootzones – Apply to top 4-5 cm at 5-10 tonnes/ hectare.

To increase CEC – Min. 1 tonne/ hectare, after “microtining”. Overdose impossible.

 

Packing Big bags and plastic sacks on pallets or loose in tipper trucks.

Storage Store in dry conditions in well-closed bags.
