Humus 100

Active Carbon >80% in soluble powder.

High quality, highly soluble humic & fulvic acid powder.

>80% humate as humic and fulvic acids (with potassium).

Humic and fulvic acid are the most active components of soil carbon (organic matter). Microbes use active carbon to improve soil structure, moisture retention and suppress disease.

Humus 100 is a cost-effective way to add active carbon to your soil.

We recommend using Humus 100 every time you fertilise to:

  • Improve soil by holding moisture & nutrients
  • Reduce the impact of salinity
  • Promote soil biological activity
  • Improve soil structure
  • Reduce lock up of phosphorus
  • Stimulate root growth & nutrient uptake
  • Reduce drought stress
  • Suppress disease

Direction For Use

Humus 100 is used to increase nutrient and moisture retention to soil.
Suitable for use as a dry soil treatment or diluted for use as a soil drench and via irrigation.
Can be applied through standard spraying equipment. Always mix under vigorous agitation.
Ensure all product is dissolved prior to application.

Pre-dilute at 1 : 10 with water; do not add solid to spray tank.

Test compatibility before using with other products.

Application Rates

Via Irrigation :
2-4kg/ha; applied 2 – 4 times during growing season. Dilute 1 : 200 with water.

Broad-acre crops and pastures:
1-3 kg/ha; applied early in season.
Dilute at 1 : 200 with water.

Fertiliser Coating:
Apply 1-2kg per tonne of urea; can be dissolved at the rate of 1kg Humus 100 into 5L water before applying to fertiliser.

Nitrogen Buffering:
1.5-2kg/tonne Urea or 350g/30L UAN
(pre-mix at 1 : 10 in water).
Mixing Order: Add water … then Humus 100 … then UAN/Urea.

Soil amendment:
Horticulture 2-4kg/ha; Broad acre 0.5-1kg/ha.

The Basics Of Humates

Humus provides the most active component of soil organic matter in a concentrated form. – Celik 2011

Good soils contain on average 1-5% HFA – don’t need much concentrated humus to make a difference. – Dong 2009

Adding humates is a cheap and practical way to control N loss & get carbon into soil. Typically fertiliser efficiency is improved by 20%. – Kasim 2011

Humus 100 contains both humic and fulvic acid (HFA). This provides the best result for nutrient retention due to increased number of functional groups embedded in them. – Taufik 2011

Humates enter into a complex reaction with a variety of organic and inorganic components of soil and influence plant growth and plant production. – Celik 2011

In clay soils, humates separate the clay particles so water and nutrients can penetrate more easily.

In sandy soils, humates provide a charged surface to hold nutrients and water. The active carbon in Humus 100 improves soil structure.
