you reduce the risk of stress to the turf to the lowest level.

with Humic Acid 11Humic Acid
Our fertilisers based on humic acid are produced
to have fully homogenous granules ensuring
the accurate spread of nutrients. They contain
high levels of organic matter to help improve all
round soil health, with particularly strong effects
on sand-based rootzones.
They release nutrients bound within the
rhizosphere making them available and more
accessible for uptake and can induce a “nutrient
acquisition response” which can enhance the
production of phytohormones. The high organic
matter content provides fuel for microbes and
general soil biota along with several forms of
nitrogen to provide balanced steady release of
nitrogen for strong healthy growth.
Scientific research has found that humic acid

• Increase water holding capacity
When applied they can help reduce the impact

environment more conducive for turf roots with
increased water and nutrient capacity.
Indigrow has two specialist soil amendment
products which are aimed at enhancing quality

by groundspersons and turf managers to maximise
water and nutrient efficiency across a range of soil
profiles and in the challenging climatic variations
prevalent in recent years.
