Potassium fulvic acid is a relatively popular fertilizer in recent years! I believe that many friends are not unfamiliar with potassium fulvic acid, and its applications are especially wide, including water-soluble fertilizers, biological fertilizers, compound fertilizers, and even some pesticides. Potassium Fulvic Acid!
But recently, a friend said that I have been using potassium fulvic acid for two years. I have used it a lot this year. There are still a lot of celery sprouts and roots in the field!
Potassium fulvic acid has no effect. What is going on?
There are two specific reasons:
1. Improper use.
When using potassium fulvic acid, cat friends must avoid the following taboos.
1. When using potassium fulvic acid, be sure to pay attention to the secondary dilution. Direct flushing will cause root burning, and the seedlings will become smaller and fragile.
2. In addition, potassium fulvic acid should be used as soon as possible after adjustment. Do not use it in high temperature, strong light or rainy days, otherwise its effect will be weakened.
3. If there is rain within 1 day after spraying potassium fulvic acid, you should re-use it, and be careful not to overuse it.
4. The soil used is severely degraded, salinization, disease accumulation and a series of problems, and lack of a healthy soil environment.
There are often various kinds of potassium fulvic acid on the market. If there are too many things, there will naturally be fakes! Then, the potassium fulvic acid you use cannot be used, it is likely that you have bought fakes!
Here's how to distinguish the true and false of potassium fulvic acid: There are four steps to identify the true and false potassium fulvic acid.
1. Look at the color.
High-quality potassium fulvic acid is usually black. If the color is too bright, dye or other ingredients can be added.
2. Smell the smell.
Potassium fulvic acid generally has no other smell. If it has a strong sour or ammonia smell, it can be judged as fake.
3. Touch yourself.
Potassium fulvic acid has relatively strong permeability, and it will stick to your hands easily if you touch it with your hands.
4. Determine the solubility.
Pour potassium fulvic acid into water, some of it will dissolve into brown. If the color is too dark or dissolve into mushroom shape, it may be defective.
All of the above are the reasons why potassium fulvic acid has no effect. Of course, some people think that potassium fulvic acid is more effective. Potassium fulvic acid has three main functions:
1. Increase soil fertility.
By improving the soil aggregate structure, loosening the soil, increasing the soil's ability to retain water and fertilizer, adjust the PH value, reduce the content of soil heavy metals, and reduce the harm of salt ions to seeds and seedlings.
2. Improve the absorption capacity of nitrogen, phosphorus and potassium of crops.
Fix nitrogen, dissolve phosphorus, activate potassium. In particular, potash fertilizer has a significant effect on increasing roots, strengthening seedlings, resisting stubble, disease, and improving crop quality.
3. Promote root growth.
Potassium fulvic acid can enhance the adhesion and rapid absorption capacity of plant roots, especially for physiological diseases caused by the lack of trace elements.
