Frequently Asked Questions

Is the dilution rate the same for applying foliarly versus drenching (applying at the roots)?

Yes. The dilution rate is the same for any application. Please be aware that leaf burn can occur when foliar treatments are applied incorrectly, such as during the day. The best time for foliar application is at night, late evening (after 8pm), or early morning (until 6 am) because that’s when leaf stomata are open, allowing for an effective nutrient uptake. Proper foliar application should result in no leaf burns.

No. Sapropel is a naturally originated microbial cell-free colloid structure. Check out the microbial analysis. 

Humuson is made from raw material, sapropel, which is a freshwater lake sediment that has decomposed naturally in non-aerobic conditions for more than 10,000 years. Sapropel naturally contains more than 40 different nutritional elements. The process of extracting Sapropel not only helps create our unique products but restores the biotop of the freshwater lakes from which it’s extracted, preventing them from drying out.This leads to the restoration of fish populations, beetle colonies and other important participants in the lake’s ecosystem. Moreover, the restoration of the lake’s ecosystem leads to the increase of carbon dioxide uptake from the environment.

No. It was experimentally established that the sapropel of the source lake does not have a harmful or toxic effect on the CNSs functional state and the liver, kidneys, heart, and stomach of rats. Sapropel does not exhibit sensitizing and locally irritating properties and belongs to the class of practically non-toxic substances (toxicity Class V). Here is a link to the full toxicology report.

Yes! Humuson is suitable for hydroponic systems. Since it’s organic and promotes the growth of beneficial microbes, you might need to clean your system a bit more frequently. Ultimately, it leads to a richer taste and bloom quality in your crops. Choose the Humuson 200 product for hydroponics systems. If you are pretreating the seeds, soak them in the solution of 1:400 (double the water).
