Abstract
The motivation for the study was the need to obtain data on the effect of humic acids isolated from brown coal on soil fertility and plant development. In our study, we conducted experiments with plants to isolate humic substances from brown coal and study its physicochemical properties and the effect of the resulting fraction on the growth of Phoenix dactylifera date palm plants in laboratory conditions. The isolated humic acids had a density of 1.0416 g/cm3 and the dynamic viscosity was 1.84*10-3 Pa*s. The mass fraction of humic substances was 56%. As a result, when watering date palm plants with a 1% solution of humic substances, plant height increased by 41.5 in 1 month, leaf width by 80, and leaf length by 15%, compared with the control variant. The results of physicochemical experiments prove that humic substances from brown coal promote the level of plant nutrition.
