Abstract
This study evaluates the effectiveness of a locally produced humic preparation, Humate with CO₂, in improving spring wheat yields in the forest-steppe zone of Northern Kazakhstan.When applied both before sowing and as a foliar topdressing, the fertilizer increased wheat yield by an average of 66% compared to unfertilized controls.No negative effects, such as plant burns, were observed when agronomic practices were properly followed.The highest yield, 41.7 q/ha, was achieved at a dose of 6 L/ha, exceeding the control by 18.3 q/ha.Similar improvements were recorded at doses of 2 L/ha (36.6 q/ha) and 4 L/ha (38.4 q/ha).The preparation also shortened the maturation period by 2-3 days and increased plant height by 4-7 cm.These results suggest that Humate with CO₂ enhances nutrient uptake, accelerates phenological development, and promotes vegetative growth, even under limited rainfall conditions.Further research should investigate its long-term impact on soil health, economic feasibility at scale, and application to other crops and regions.This study contributes to sustainable fertilizer practices and food security in Kazakhstan and similar environments.
