Humic preparations are valuable sources of humic acids, which increase soil fertility and have growthregulatingactivity on agricultural crops. Application of new humic preparations from local weathered coalsallows providing agricultural producers with domestic preparations. To identify the optimal doses of application,we conducted a series of experiments on germination of vegetable seeds to increase their germination.The results of the study showed that humic preparations in different concentrations may not have the same activityon the seeds of plants of different species. The best germination rates are as follows: for white cabbageseeds after soaking in a solution of potassium humate at a concentration of 0.005 %, for eggplant seeds — amixture of potassium and sodium humate at a concentration of 0.5 %, for tomato seeds — potassium humate0.005 %, for sweet pepper seeds — a mixture of potassium and sodium humate 0.005 %, for cucumber seeds— a mixture of potassium and sodium humate 0.01 %. The results can be used for agricultural and greenhouseapplications.
