Humic Acid Manufacturer: The Principle Behind the Use of Foliar Fertilizers
Fertigation is a method of applying fertilizer; although it offers numerous advantages, it cannot be applied universally. Below… Humic acid manufacturer Let’s take a look at the principle behind fertigation.

1. Based on the growth characteristics of crops, nutrient uptake occurs both through the foliage and the roots. The root system primarily supports early-stage growth by absorbing major nutrients such as nitrogen, phosphorus, and potassium from the soil, while foliar fertilization typically relies on liquid fertilizers absorbed via stomata to replenish essential nutrients. Fertigation, on the other hand, leverages the roots’ capacity to absorb nutrients by applying water-soluble fertilizers.
2. The “barrel principle”: All nutrients operate according to this principle—when a crop lacks even one essential nutrient, its growth is directly impaired. Foliar fertilizers capitalize on this characteristic by formulating balanced nutrient blends as their foundation.
3. Optimize the fertilization process: Conventional fertilization typically relies on compound fertilizers, which can have adverse effects on soil quality, and applying fertilizer by covering it with soil may easily damage root systems. By adopting flush application and incorporating humic acids, we not only replenish nutrients but also promote soil improvement.
