Different Effects of Humic Acid Series Products at Different Growth Stages
Crops have different reactions to humic acid series products in different growth periods and the early growth effect of general crops is obvious. Humic acid series products have the most significant effects in the period of the most vigorous life activities of crops, the period of the stronger physiological metabolism and enzyme activities of organisms. Such as seed germination, seedling root, seedling transplanting, tiller, poplar grouting, and other key periods.
It is particularly emphasized that humic acid itself cannot be used as a single nutrient supply, but should be combined with the application technology to better exert its intensive, functional, and personalized effects. Due to the different sources, quality, and product characteristics of humic acid, we should choose humic acid series products, application methods, and fertilizing amounts according to local conditions, such as soil types, crop types, climatic conditions, and other factors, to give full play to the role of humic acid series products in increasing yield.
