Darina is a natural, contaminant-free, liquid organic fertilizer – an organic mineral resource, extracted from the bottom of glacial lakes situated in undisturbed and uncontaminated areas.



The history of Darina began ca. 10 000 years ago, in the north-western regions of today’s Russia, when a receding glacier formed a number of lakes.

Remains of plants and microorganisms living in their perfectly clean fresh waters accumulated on lake bottoms over thousands of years. Darina is a result of anaerobic decomposition of aquatic plants as well as remains of various organic and mineral forms.

Darina is a contaminant-free liquid organic fertilizer. It is extracted from the bottoms of glacial lakes situated in undisturbed and uncontaminated areas. In effect, when used and stored according to instructions, it is both safe to human and animal health, and environmentally-friendly.

Darina’s three basic ingredients are: water, mineral fractions (sand, clay, carbonates, phosphates, silica, ferric compounds, etc.) and organic fractions with a complex structure and composition.

Physicochemical tests have shown that Darina contains enough nutrients that are essential for the growth and development of vegetables and other plants. Moreover, its high organic matter content (over 30%) has a beneficial effect on soil structure and fertility, and hence on plant growth and crop yield. Darina can be used for vegetable cultivation both in open fields and under cover (in polytunnels, greenhouses, and cold frames). It is especially recommended for growing such species as: tomatoes, peppers, cabbage plants, root crops, and many more.

Thanks to the concentrated form, Darina is more economical to use, offering far better results than other organic fertilizers.

Additionally, it allows to reduce fertilizing rates by 30 – 50%.

Plants fertilized with Darina are stronger and tastier, at the same time developing a more robust root system and immunity to diseases.

Darina improves soil structure, thickness and water retention capacity; it also enriches the soil with organic matter, releasing plant nutrients (macro- and microelements).



- can be used for sprinkling soil prior to ploughing, cultivating, or turning

- contains humic and fulvic substances

- contains naturally mineralised compounds

- triggers metabolism, absorption of macro- and micronutrients, also increasing photosynthesis

- increases the content of proteins, carbohydrates, vitamins, and other beneficial nutrients

- biostimulates plant growth

- increases crop yields and accelerate plant growth

- increases crop yields by 30 – 80%, depending on the species

- strengthens plants, improving fruit production

- improves the taste of plants, making them healthier and more nutritious for people and grazing animals

- improves the look of plants

- improves and enrich soil structure

- increases resistance to unfavourable environmental conditions

- reduces toxic effects of heavy metals, chemical pesticides, and other contaminants

- increases plant resistance to unfavourable weather conditions (frost, heat)

- increases resistance to diseases and pests

- strengthens plants’ growth system

- fosters self-purification processes, resulting in the removal of pathogens and contaminants

- accelerates the composting process

- conducives to reducing fertilizing rates

- can be used in combination with other fertilizers and crop protection products
