Highly concentrated humic suspension produced on the basis of vermicompost. The product contains a natural association of cellulose-degrading microorganisms with a complex of cellulolytic enzymes from vermicompost and acts as a stubble destructor.
For spraying crop residues immediately after harvesting.
Spraying stubble and crop residues immediately after harvesting
Culture:
Cereals, legumes, oil crops, corn, etc.
The use of the product ensures fast and effective decomposition of crop residues after harvesting, promotes humification of residues, suppresses fungal and bacterial pathogens, improves soil health and prevents its degradation.
Suspension
It is highly soluble in water and contains up to 10% of suspended particles.
TU U 20.1-19380560-006:2021
Certified for use in organic agriculture in accordance with the International Certification by Organic Standard for organic production and processing, which is equivalent to the European Union Regulations No. 834/2007 and 889/2008.
Safe for humans and the environment. In case of contact with eyes or skin, rinse with water.
18 months at temperatures from 3 to 25 °C. Avoid freezing and contact with petroleum products.
Packaging:
Canister 10 l
0.5 l/t of crop residues. Prepare the working solution (200-300 l/ha) on the day of use and store for no more than a day. Stir thoroughly before use.
If Humistern is used with no-till technology, the amount of working solution should be increased to 400-500 liters/ha and treatments should be carried out only at night.
It is compatible with most plant protection products and fertilizers and is recommended for use in tank mixtures. Stir thoroughly before use.
To accelerate the Humistern's operation, nitrogen fertilizers (ammonium nitrate, UAM, urea) can be added to the tank mixture.
The rates of compensatory nitrogen consumption per hectare: 10-15 kg/ha for cereals and sunflower; 8-10 kg/ha for legumes; 25 kg/ha for corn.
After harvesting grain crops, 4-7 tons of straw are left on a hectare of field. A small number of farms can use it to feed animals or make fuel briquettes, and incorporate the rest into the soil. If there is enough moisture in the soil, properly chopped and mixed with the soil, straw decomposes by 40-50% in 3-5 months, and it takes up to 3 years for complete decomposition.
During the growing season, corn produces a significant amount of biomass that is left in the field. The large volume of this organic mass and its chemical composition significantly slow down its decomposition, which negatively affects the development of the subsequent crop.
First of all, a large amount of residues complicates soil preparation and sowing, and during the growing season, as they decompose, the microbiota will compete with cultivated crops to extract nitrogen from soil reserves. Thus, instead of additional nutrition, you can get a deficit of basic elements in the soil. On the other hand, after corn stover decomposition, you can get about 10 t/ha of valuable organic fertilizer, which contains a lot of carbon and potassium.
Sunflower also produces a large amount of vegetative mass during the growth process due to its powerful stem and large leaves. After harvesting, the plant residues must be shredded and mixed with the soil so that they can decompose, mineralize and humify. Sunflower residues are returned to the field: N - 74%, P2O5 - 54%, K2O - 94%, but under normal conditions this happens in six months. Only then will organic matter be converted into mineral salts and humic substances that can be used for the next crop.
The large amount of biomass produced by rapeseed during the growing season becomes a valuable organic fertilizer when it decomposes. Therefore, rapeseed is a good predecessor, despite the high removal of nutrients from the soil. The process of humification and mineralization of rapeseed residues can also take a long time. During humification, organic matter is preserved in the form of decomposition-resistant humic acids that contain significant reserves of nutrients and energy.
These processes can be significantly accelerated by using the vermicompost-based stubble destructor Humistern. Crop residues are sprayed with this product with a small amount of compensatory nitrogen, as a result of which the nutrients are used by the successor crop much earlier.
Unlike "classical destructors", Humistern works as a biological stubble destructor, its active agronomically useful microflora has an advantage over common destructors due to its natural origin and increased resistance to extreme conditions. The strains of microbiota present in the preparation produce cellulosolytic enzymes, phytohormones, antibiotics and vitamins. Humistern also contains humates.
This multi-component composition allows it to perform several functions at once:
As an organic fertilizer based on vermicompost, Humistern is safe for humans and the environment.
