Foliar fertilizers apply nutrients to the surface of crop leaves, supplementing root fertilization. Nutrients penetrate the plant through the stomata or cuticle, directly participating in metabolism and organic matter synthesis. They are rapidly absorbed, efficiently, and require only a fraction of the amount of soil fertilizers. They significantly promote photosynthesis and increase dry matter accumulation. Common types include macronutrient fertilizers, trace element fertilizers, humic acid fertilizers, microbial fertilizers, plant growth regulators, and pesticide fertilizers.

Foliar fertilizers apply nutrients to the surface of crop leaves, where they are absorbed and function. Plant leaves have two layers of epidermis, consisting of epidermal cells. The outer surface of the epidermal cells is covered by a cuticle and wax, protecting the mesophyll cells beneath the epidermal tissue from adverse environmental conditions. The leaf surface also contains numerous tiny pores that facilitate gas exchange. Research has shown that the cuticle is composed of a polymer of long-chain fatty acids with hydroxyl and carboxyl groups. The intermolecular spaces within this polymer and the hydrophilic hydroxyl and carboxyl groups on the molecules allow aqueous solutions to penetrate the leaves. Naturally, the pores on the leaf surface provide a convenient pathway for foliar fertilizers to enter the leaves. Urea in chemical fertilizers softens the cuticle of epidermal cells, accelerating the penetration of other nutrients. Therefore, urea is a crucial component of foliar fertilizers.

PRODUCT FEATURES

Supplements deficiencies in root fertilization, rapidly replenishes nutrients, maximizes fertilizer effectiveness, and reduces soil pollution.

1. Rapid Absorption

Foliar fertilization allows nutrients to be quickly absorbed by crop leaves, entering the plant directly from the leaves and contributing to the plant's metabolism.

2. Strong Effect

Foliar fertilization allows nutrients to enter the crop directly from the leaves, resulting in rapid absorption. This can significantly increase the crop's nutrient load in a short period of time, quickly alleviating fertilizer deficiencies and maximizing the fertilizer's effectiveness. 3. High Efficiency:

Foliar spraying offers advantages such as rapid fertilizer release, high utilization rate, significant results, and ease of use, making it increasingly popular among farmers.
