How to Choose Suitable Humic Acid or Humate Products


Firstly, humic acid series products are selected according to the application method. Potassium humate, potassium Fulvate, or fulvic acid are recommended for flush, drip irrigation or foliar spraying. If it is used as bottom fertilizer, humic acid (Leonardite as raw material) is recommended and should be buried in the soil. Furthermore, do not apply sodium humate in saline and alkaline land.

Secondly, humic acid series fertilizers are selected according to the growth node. Taking fruit trees as an example, autumn mainly uses phosphate fertilizers and potassium fertilizers. The early spring mainly uses nitrogen fertilizers. Phosphate fertilizer and potassium fertilizer are used in germination and differentiation. Nitrogen fertilizer, potassium fertilizer, calcium fertilizer, and micronutrient fertilizer should be applied at the stage of fruit expansion. In addition, we need to fertilize the crops according to their preferences. For example, fruit trees, solanaceous fruit and vegetables, tobacco, sugar cane, and so on are potassium-loving crops, using potassium humate products to achieve the best effect.

Finally, humic acid series fertilizers are selected according to crop type and cost. Humic acid fertilizer is divided into humic acid simple fertilizer, humic acid compound fertilizer, humic acid organic fertilizer, humic acid organic-inorganic compound fertilizer, humic acid trace element fertilizer, etc.

For field crops, it is recommended to choose humic acid compound (mixed) fertilizer, which is convenient to use and cost-effective. For vegetables and fruit trees, humic acid organic fertilizer, humic acid organic-inorganic compound fertilizer, or humic acid trace element fertilizer can be selected. The organic matter in these fertilizers can reach 20% ~ 45%, which can effectively improve the taste and color of crops.

If it is used for flushing or foliar spraying, it is recommended to choose water-soluble fertilizer containing humic acid or fulvic acid. Although the price of this kind of fertilizer is higher, the effect is fast and effective, so be used for the high-value cash crop. Humic acid series products can be used in the whole growth period of crops, but for economic considerations, it can be used after transplanting, before flowering, expansion, and color turning 4 critical periods of 1 ~ 2 times each, the effect will be better in expanding period and color turning stage with spraying application.
