There are various kinds of potassium fulvic acid from mineral sources on the market. Do you know how to identify the advantages and disadvantages of potassium fulvic acid from mineral sources and how to use potassium fulvic acid from mineral sources correctly?
There are four steps to identify the quality of mineral potassium fulvicate, namely, look, smell, touch, and detect.
1. Look at the color: High-quality potassium fulvicate is usually black, and appears black and bright when illuminated with a flashlight. General-quality potassium fulvicate is black and not bright enough.
2. Smell the smell: Mineral potassium fulvicate generally has no other odor. If it has a strong sour smell or ammonia smell, it can be judged as a fake.
3. Feeling: Mineral potassium fulvicate has a relatively strong penetration ability and will easily stick to your hands.
4. Test the solubility: Pour a small amount of potassium fulvic acid from the mineral source into the water. It will dissolve in brown color and you can see a stringy shape. If the color is too dark or it dissolves in a mushroom shape, it may be an inferior product.
Although the mineral potassium fulvicate is very good, you must master the correct method of use.
1. When using potassium fulvic acid, be sure to dilute it twice. Direct flushing will cause root burning and the seedlings will become small and weak.
2. In addition, potassium fulvic acid should be used as soon as possible after preparation, and it should not be carried out under high temperature, strong sunlight or rainy days, otherwise its effect will be weakened.
3. If it rains less than 1 day after spraying potassium fulvicate, you need to reuse it. Be careful not to use too much.
4. If the soil used is seriously deteriorated and has many problems such as salinization and disease accumulation, and there is no healthy soil environment, the effect of potassium fulvic acid will also be compromised.
