We make our planet cleaner

New Generation of Organic Fertilizers


About us

NORDIC BIOPROTECT LLC aims to present the latest developments from the leading Bulgarian producer of bio fertilizers BIOHUMAX® on the EU market as well as GCC Countries.

Since 2014 presentation of the product began in the Scandinavian Countries with main office in Sweden, and at the end of 2016 the product presentation project has been started in Czech Republic with the opening of new company's office in Ceske Budejovice.


What is Biohumax® ?



We all fertilize our plants. Unfortunately a lot of the fertilizer we use is lost by runoff, or becomes bound to the soil and is unable to be used by the plant, due to the amount of time it takes the bacteria present in the soil to break down the nutrients into usable portions.

Our product is a fertilizer of a new generation. It is created with the idea to combine the most effective for plants’ growth components of different kind of bio fertilizers and bio stimulators.

The first and the most important characteristic of this brown odourless liquid, is that it is 100% natural, organic product. There are not any genetically modified organisms, microorganisms or bacteria included in the process of its production. All components are naturally occurring materials.

It is produced from Earthworm (red Californian worm) castings. Earthworms (red Californian worms) excrete a highly nitrous fertilizer (called castings) which contain 5 times the available N, 7 times the available phosphorus, 3 times the exchangeable Magnesium, 11 times the available potash and 1,5 times the calcium found in 6 inches of top soil.

Earthworm Castings is odourless organic material, which contains a high percentage of humus and humic acid, an ingredient, which provides binding sites for plant nutrients and aids in the prevention of harmful pathogens, fungi nematodes and bacteria. Improves the aeration and water retention abilities of the soil.

Humic acids in the soil serve numerous functions. Among the most significant are: Physical modification of the soil structure, increasing soil aggregate stability and thus improving water infiltration, aeration, soil tilth and workability, and reducing erosion losses from run off.

Humic acid defies precise description except in very general terms. Black or very dark brown high molecular weight organic polymer is as good a description as any.

A substantial fraction of the mass of the humic acid is in carboxylic acid functional groups, which endow these molecules with the ability to chelate positively charged multivalent ions (Mg++, Ca++, Fe++, most other “trace elements” of value to plants, as well as other ions that have no positive biological role, such as Cd++ and Pb++). This chelation of ions is probably the most important role of humic acids with respect to living systems. By chelating the ions, they facilitate the uptake of these ions by several mechanisms, one of which is preventing their precipitation; another seems to be a direct and positive influence on their bioavailability. Many organisms can exploit dissolved organics degree if they are present and humic acids may be taken up by this mechanism. Another paradoxical effect of humic acid is the detoxification of heavy metals. One might expect them to be more, not less toxic by humic acids, but the studies show detoxifying effect.

The other extremely important component of the product, are the effective micro organisms.Over 50 bacterial and not less than 3 fungi species can be found in the formula of the product. The species can be divided, according to their temperature resistance, to psychrophili (t 20°C). The mesophili are the microorganisms prevailing into the final product.

The product represents a mixture of carbohydrates, proteins, fats, hemicelluloses, lignin, and mineral salts that widely vary in their concentration.

Content of dry substance in [%]:

  • Soluble in water compounds 2-30% (carbohydrates, starch, amino acids, ammonia salts, etc.)
  • Soluble in ether or alcohol compounds (fats, oils, wax) – 1 –15%;
  • Proteins 5-40 %;
  • Hemicelluloses 10-30 %;
  • Cellulose 15-60 %;
  • Lignin 5-30 %;
  • Ash 2-5 %;

By adding the product to the soil we can improve soil quality and our plants’ overall health and this can be achieved 100% naturally and effectively with our product.

Our fertilizer is a Bulgarian product , which was certified under the EU Laws under the trademark BIQ® as organic, bio-stimulator for plant grow.

CWS BeteiligungsGmbh registered it under ID Number: 303504 with the INFOXGEN Institute.

There are already many institutions and farmers on the territory of Austria interested in BIQ®. Tests were carried out from the Agrarian College in Tuln on many plants for two years and the results were definitely positive.

Effects from the application of liquid eco-fertilizer BIOHUMAX®

  • increases yields from agricultural products up to 50%;
  • improves plant metabolism and facilitates plant breathing;
  • suppresses the agents of some major economically significant diseases in plants;
  • may replace synthetic fertilization up to 100%;
  • is an economically viable source of nutrients for plants and soils;
  • is a powerful bio-stimulant of plant growth and development;
  • contains natural soil microflora, extremely valuable for plants and soils;
  • is a new generation potassium humate;
  • is extremely rich in microelements, salts and minerals, necessary for the balanced nutrition of the plants.


During the breeding of Red California worm or Tiger worm, biomass is produced, also known as Worm compost. The product thus received is solid, with porous structure and comparatively high humidity. It is rich in humin and fulvin acids, as well as macro- and micro elements in helate (easily assimilated by plants) form, salts and minerals. Worm compost is suitable for fertilizing soils on small areas, where its introduction is done manually and is accompanied by efforts to achieve correct dosage. BIOHUMAX® is created as liquid formulation (water extract) of Worm compost from Red California worm, to help farmers avoid the inconvenience and problems of the direct application of Worm compost.

The product conforms to testing certificates, issued for each manufactured batch by the authorized state service for control and testing of fertilizers.

Project Studio Company has conducted a series of tests of humates – analogous products of BIOHUMAX®, available on the world market, and the results show that many of them are insufficient to achieve a positive end result for farmers. In our opinion, some drawbacks that play a negative role for the accepting the humin-containing preparations by world agriculture, are the low content of humin acids (under 0,20% in the liquid preparations and less than 10 % in the dry substance); “raw” or untreated humin acids, found in sufficient concentrations in the products’ contents, but ineffective in terms of the nourishment of the plants; products with treated humin acids with energy-consuming technologies reaching the farmers at inaccessible and economically unviable prices; even products marketed as humates, which do not contain humin acids.


BIOHUMAX® contains over 50 types of bacteria and not less than 9 types of moulds. They can be subdivided depending on the temperature range into psychrophiles (t40°С). The predominant microorganisms in the end product are mesophiles.

Although bacterial content in the compost is very high (108 -109 cells per 1 g moist compost), due to their small size they comprise less than 50 % of the total microbe biomass. Some species (genus Bacillus, Clostridium) form endospores, resistant to high temperatures and draught. Actinomycetes grow significantly slower than bacteria and moulds and during the early stages of composting they are no competition. They appear at the later stages of the process, when they become too many and form at a depth of 10 cm below the surface a clearly visible layer of actinomycetes, white or grey in color. They can reach up to 105-108 cells per 1 g of moist compost, which is less than the bacteria. Moulds play an important role in cellulose decomposition and the condition of the composting mass should be regulated in such a way as to optimize their activity. Temperature is an important factor, because moulds die at t<55°С. Moulds contain both thermophiles (growing at t=50°С), and mesophiles (growing at t=28°С). After temperature is reduced, they again proliferate in the cooler areas throughout the entire mass.
