In the case of planting various crops, including street-grown crops, fruit tree crops, economic development crops and their vegetables and fruits, etc., when the soil environment quality of the field and cultivated land are not good, or when the roots of crops grow and develop, digest and absorb When the vigor is weak, or when the growth is not good enough to increase the growth, or when the ability to work hard to improve the resistance to promote strong trees, or when the crops are in the stage of growth and development, we are in the field. Putting some potassium fulvic acid (especially mineral potassium fulvic acid) on the crops can usually bring significant benefits to the soil and crops, and most of the potassium fulvic acid can be widely used in various crops. The usage is also very flexible, and the actual effect is very good after application.

However, many good friends of farmers often say: Potassium fulvic acid is useless, it is a waste of money to use it, and I have used potassium fulvic acid on crops in the field and have not seen any good actual results; there are also some farmers. A good friend also said: Potassium fulvic acid can't be used. After I use it, the crops in the field look worse, and some crops even have their roots damaged by potassium fulvic acid and burnt seedlings!

As often said in the small back basket for agricultural technology promotion in the topic of this article, potassium fulvic acid is a multifunctional fertilizer that is often used by our good friends in agricultural planting and has good actual results after application, but if fulvic acid Potassium mishandling, after we apply potassium fulvic acid to the soil layer and crops, either will not see significant good actual effects, or will lead to poor inhibitory effects on the growth and development of crops. In one situation, if you prepare potassium fulvic acid, you also need to understand the fertilizer characteristics of potassium fulvic acid first, and grasp the reasonable operation method of potassium fulvic acid, otherwise you will waste money and have no practical effect. !

Today, the small back basket for agricultural technology promotion will be divided into several articles (one article has too much content) to take us to a deep and correct treatment of potassium fulvic acid, and tell everyone how to use it well and use it correctly!

1. Why is there a "potassium" in potassium humate? There is "potassium" in potassium humate. Is it potassium fertilizer?

1. Why does potassium fulvate have "potassium"? What is the "potassium" in potassium humate?

We all know that humic acid includes fulvic acid, brown humic acid, black humic acid, etc. There are many kinds of humic acid, and fulvic acid is the organic chemical with the strongest activity, the least molecular weight and the most easily absorbed by crops in humic acid. One of the chemical substances, although the effect of fulvic acid is very good, the reliability of fulvic acid in storage, application and actual effect is very poor. We add an appropriate amount of zinc element (potassium oxide) to potassium fulvic acid to make it It can be changed into a reliable inorganic salt, which can greatly improve its reliability in storage, application and actual effect. One sentence summary: potassium in potassium humate plus potassium oxide, in fulvic acid Adding "potassium" can make it more stable in general and more convenient for everyone's storage, production, processing and application.

2. Is potassium fulvic acid potassium fertilizer?

Potassium humate contains a certain amount of "potassium" element, perhaps some good friends of the villagers who do not understand fertilizer expertise will incorrectly use it as potash fertilizer, or some stores selling agricultural products will also inform farmers of "flavonoids". Potassium acid contains zinc, so it is also a potash fertilizer".

Actually not. Although potassium fulvic acid contains a certain amount of zinc, the potassium content in potassium fulvic acid is relatively low, and the potassium content in it cannot reach the standard of potassium fertilizer. Potassium can be regarded as potash fertilizer, nor can it replace potash fertilizer, so everyone should not use it incorrectly as potassium fertilizer, everyone can only use it as a multifunctional fertilizer that is beneficial to the growth and development of soil layers and crops.

Why do you say that? The following agricultural technology promotion small back basket will give you the reasons: potassium fulvic acid is divided into two categories: biochemical potassium fulvic acid and mineral source potassium fulvic acid. The potassium oxide content in biochemical potassium fulvic acid is generally only 8 percent or so, the potassium oxide content in mineral potassium fulvic acid is only about 12 percent. Taking mineral potassium fulvic acid fertilizers with high potassium oxide content as an example, if a bag of fertilizers marked with potassium fulvic acid is in The standard on the outer packaging bag is that the content of potassium fulvic acid is 15%, so if you convert it, then the content of potassium oxide in this bag of fertilizer is actually less than 2%. If we use this less than 2% of potassium to give crops Potassium supplementation, then the results are obvious.

2. Is fulvic acid the same as potassium fulvic acid? What is the connection and difference between them?

First of all, fulvic acid and potassium fulvic acid are two different types of items, and the two should not be confused.

From the origin of the two, fulvic acid is an acidic organic chemical substance formed by dissolving plant residues. Its organic composition is very simple, mainly aromatic methyl carboxylic acid compounds, and There is no zinc in it, it can be used as a growth stimulator for crops or green plants with naphthalene acetic acid, and can also be used for the production of potassium fulvic acid and other fertilizers (such as leaf fertilizer, water-soluble fertilizer, organic fertilizer, microbial fertilizer, The application of raw materials for organic compound fertilizers, etc.) and potassium fulvic acid is the salt form of fulvic acid, which is essentially a slightly acidic inorganic salt with fulvic acid and potassium. They all contain some other nutrients (such as carbohydrates, proteins, sugar acids, etc.), and it should be used as a multifunctional fertilizer in application.

In terms of the instructions for use of the two, fulvic acid is more suitable for flushing, drenching, root irrigation and fertilizer spraying, while potassium fulvic acid can be applied in fields at the same time in addition to flushing, drenching and root irrigation. However, fulvic acid is not suitable for immediate application in the soil environment. In addition, we generally have very little raw powder or source liquid of fulvic acid that can be purchased immediately in the sales market, while fulvic acid is not suitable for immediate application. Potassium humate fertilizers are widely available in the market and can be easily purchased.

In terms of the use of the two, the function of fulvic acid is mainly to adjust the growth and development of crops, promote the digestion and absorption of crops, and improve the ability of crops to resist stress (mainly adjustment), while potassium fulvic acid removes the above effects. In addition, there are certain nutrient supply, active soil layer, promoting roots and seedlings, and promoting perfection (the key adjustment effect plus the effect of fertility). It is suitable for direct application and must be used together with other light fertilizers and other fertilizers.

3. Is potassium humate an acidic substance or an alkaline substance?

The small back basket for agricultural technology promotion has already been mentioned to us above: fulvic acid is an acidic organic chemical substance (acid-base), and the potassium fulvic acid produced after adding "potassium" to fulvic acid belongs to Inorganic salts that are weakly alkaline (alkaline).

In view of this, many good friends of farmers often do not pay attention to this. Later, when using potassium fulvic acid together with other fertilizers, pesticides, fungicides, insecticides, etc., they should pay more attention to the commonly used fertilizers and the pH of medicines, and minimize the use of potassium humate. It is mixed and applied together with chemical substances with strong acidity and alkalinity to prevent the acid-base neutralization reaction during mixing and mixing, which reduces the actual effect of potassium humate and other fertilizers.

4. What are the types and classifications of potassium fulvic acid? What is the difference between biochemical potassium fulvic acid and mineral potassium fulvic acid?

At present, there are many types of potassium fulvic acid and fertilizers with potassium fulvic acid on the market, such as the common and common water-soluble fertilizers, bacterial fertilizers, organic fertilizers, leaf fertilizers and some compound fertilizers. Potassium fulvate can be added and applied in fertilizers for production. In terms of classification alone, there are currently two key categories of potassium fulvate on the market, one is a very general biochemical potassium fulvate , one is a better mineral source potassium fulvic acid.
