Humic acid is a natural organic acid macromolecule with complex structure and multiple functions. It has a variety of physiological functions and disease prevention and control functions, and has great development and application prospects in agriculture and forestry.
We often hear that humic acid is an essential substance for plant growth. So why is humic acid so important for plant growth? The author will confirm this by explaining the importance of humic acid for plant growth.
The importance of humic acid for plant growth
Although many scientific and technological literatures do not mention that humic acid is an essential substance for plants, but we can prove in practice that plants need humic acid.
(1) Some people who destroy forests and open up wasteland,
Planting crops in one place is often abandoned for 1-2 years. The reason is that after planting crops, a large amount of organic matter in the soil is consumed, and crops cannot be planted without supplementation. And 70% of soil organic matter is humus containing humic acid. Generally, land with less than 3% soil organic matter cannot be used as nursery land and farmland.
(2) When we apply humic acid to crops, it can enter the plant body from roots, stems, and leaves. Wheat isotope experiments have confirmed this. Plants can absorb such substances from the soil and operate in the plant.
(3) When we apply humic acid or fulvic acid, we can see obvious changes in the shape, color and size of crops, such as becoming greener, stronger, and growing more vigorously. Prove that humic acid is involved in plant metabolism, and play a good role in promoting.
(4) Planting in the same crop with high soil organic matter content, usually yields higher than crops with low soil organic matter content, which also proves the role of humic acid.
The above proves that the growth and development of plants is inseparable from humic acid. Plants use it to show good economic and ecological benefits through the physiological effects of humic acid in plants. So what are the physiological effects of humic acid in plants? Tomorrow, the author will update the article : “Physiological Benefits of Humic Acid for Plants”.
