Siberian Humate Powder

Gumat SP75 Humate PowderGumat Siberian SP75 (Sodium Potassium, 75% Humic Acid) Humate Powder was created by Dr Boris L Levinsky and is produced in Irkutsk, Eastern Siberia, Russia. Why "Gumat"? Well... the name actually comes from the fact that the Cyrillic alphabet has no 'H', so the Russians use a 'G' in its place.

Humate (an environmentally safe plant growth stimulant) is the organic base of soil which is rich in humic acids and is known for its ability to promote the development of good soil structure, healthy plant growth and retention of applied fertilisers. Humate also increases the water holding capacity of the soil.

Gumat Siberian SP75 Humate Powder is available in 200gm packs for home gardeners and 12kg bags and 29kg drums for the lifestylers and farmers.

A Brief Introduction to Humate Technology

The term ‘Humic Acid’ represents a group of powerful natural substances that are so complex that science will not be able to replicate them for generations to come. Because of their incredible complexity, all humic acid products must be derived from naturally occurring deposits, which are found in certain types of oxidised Lignite. The humic acids in these natural deposits have withstood millions of years of weathering, yet they still have not broken down or leached out of the earth into the water table. Therefore, they are extremely insoluble and inactive in their natural state. Prior to our new technology, techniques used to make the humic acids soluble have proven to be quite complicated and costly. This has resulted in the unfortunate practice of applying large volumes of the raw material to the soil in the hope that some of the humic acids will become available to the plants and soil over time. However, even if a very small fraction of the humic acids in the raw material were soluble or able to be released over time, this practice is an extreme waste of a valuable natural resource and is nothing more than a hit-or-miss approach.

Through many years of research, we have developed a new breakthrough technology for the production of maximum quality humic acid products from their natural deposits. Our specialised processing activates the insoluble humic acids found in the lignite and makes them available for use by the plants and the soil. This allows for very precise application and utilisation of the humic acids. After our processing, 10 kg of our activated Gumat SP75 Humate Powder will provide more value to crops and soil than 1,000 kg of the raw material. By maximising the efficacy of the raw material, we can also help ensure that the supply of these natural deposits will last until science is able to fully understand and replicate the functions of humic acid.

Benefits of Gumat Siberian SP75 Humate Powder

  • Healthier soils
  • Better animal nutrition and health
  • Breaks up compacted soils
  • Improved crop growth and quality
  • Improved moisture retention
  • Frees up soil bound nutrients
  • Improved fertiliser efficiency
  • Increase biological activity in the soil
  • Reduced impact on the environment

Recommended Usage of Humate Solution in the Home Garden

Soaking of seeds: 2-3 tsp per 10 litres of water:

Tomatoes 3 days
Cabbage and Squash 2 days
Cucumbers and other vegetables 1 day
Potatoes 12 hours before planting

Before soaking seeds, keep the solution 24 hours at room temperature.

Watering and spraying during vegetative period: 1 tsp per 10 litres of water:

  • Vegetables require spraying and watering every 10-12 days 4-5 litres per square metre (m2)
  • trees and bushes 4 times a season, 5-6 litres per plant
  • flowers need spraying once a week

Recommended Usage of Humate Powder for Pasture and Crops

For Foliar Spray and Overhead-Irrigation Applications:
ALL foliar and overhead-irrigation application to crops should be made with 15 grams of the SP75 Humate Powder per 10 litres of water. Crops may be foliar sprayed with any volume of water; however it is recommended to use at least enough water to uniformly cover all plant leaves.

Yearly Humate Needs of Various Crops

Type of Crop Recommended Amount of Humate to Apply per Year
Grain Crops (Wheat, Rye, Oats, Barley, Pasture etc.) 5 - 9 kg SP75 Humate Powder per hectare
Leaf Crops (Dill, Parsley, Lettuce, Herbs etc.) 5 - 6 kg SP75 Humate Powder per hectare
Vegetables (Cucumbers, Tomatoes, Peppers, Broccoli etc.) 11 - 14 kg SP75 Humate Powder per hectare
Root Crops (Potatoes, Beets, Carrots etc.) 11 - 17 kg SP75 Humate Powder per hectare
Berries (Strawberry, Raspberry, Blueberry, Currants etc.) 9 - 14 kg SP75 Humate Powder per hectare
Industrial Crops (Cotton, Rape etc.) 5 - 7 kg SP75 Humate Powder per hectare
Fruits (Apples, Cherries, Plums, Citrus, Banana etc.) 11 - 22 kg SP75 Humate Powder per hectare
Melons (Watermelons, Cantaloupes etc.) 5 - 8 kg SP75 Humate Powder per hectare


  • Soils that have high levels of stable humus and nutrient content (as sometimes found in established no-till farms) may not need the larger doses of soil-applied humate. In this case the optimal results can be likely achieved with seed treatment and repetitive spraying and/or irrigation.
  • When applied together with fertilisers or pesticides, the use of humate increases the efficacy of the companion materials. In most cases, systemic pesticide rates can be reduced by 25% or more when the humate is added to the application. The total annual use of nitrogen can be reduced by 20% or more when the yearly recommended rate of humate is applied to the crop. In all cases, we suggest using personal experience and experimentation to determine the rates of companion products that will provide acceptable performance.

First Aid Warnings

Supply fresh air. If required, provide artificial respiration and seek medical advice. No toxic effects are known. Wash with water and soak and rinse thoroughly.
Rinse opened eye for several minutes under running water. No eye reaction effects are known, but the powdered nature of the product could cause physical discomfort. Seek medical advice if irritation persists.
No detrimental effects of ingestion are known. Seek medical advice if discomfort arises.
No exposure limits have been determined and no particular reactions to this product have been reported. If combined with other products, use their MSDS information.

Product Spillage

Vacuum if possible to avoid generating airborne dust. Avoid breathing dust. Wear an approved respirator. Avoid adding water to the spill as the material will permanently stain most surfaces and may become slippery when wet.

Handling Precautions

Use appropriate respiratory protection for airborne particulate based on consideration of airborne workplace concentration and duration of exposure.
Use local exhaust for ventilation; no mechanical or special exhaust is necessary.
Recommended as a precautionary measure only.
Safety goggles or glasses are recommended.
As appropriate for the work environment. Dusty or dirty clothing should be laundered after use. Product may stain clothes.
