Is the effect of mineral potassium fulvic acid really wonderful? Sometimes the actual effect is not very good

At present, people pay more and more attention to mineral potassium fulvic acid. Some manufacturers also boast that mineral potassium fulvic acid has become a "fairy fertilizer", saying that it is omnipotent. Potassium humate, everyone should understand it more reasonably. It is not omnipotent. Its actual effect needs to be coordinated with many necessary conditions. Next, I will talk about some of the mineral potassium fulvic acid. The truth.

1. Mineral source potassium humate "helps the weak but not the strong

The actual effect of increasing the yield of mineral potassium fulvic acid is different under different soil types, different soil organic matter components, and different physical and chemical properties of soil.

Under normal circumstances, the actual effect of increasing yield in fields with poor soil organic matter is significant, while the actual effect of increasing yield in fields with rich and colorful soil organic matter is not significant.

In some sandy soils and acidic soils, the actual effect of increasing the yield of saline-alkali land is remarkable. For example, in Inner Mongolia, Shaanxi and other sandy soils, the use of mineral potassium fulvic acid can increase the yield by 17.1%-85.7%. In Inner Mongolia, Hebei, The actual effect of increasing yield is also very significant in saline-alkali soils such as Shaanxi, and it is also good to increase yield under necessary conditions in acid soils such as Dawukou, Ningxia.

Mineral potassium fulvic acid has a very good effect on soils with low alkali-hydrolyzed nitrogen components, and the fertilizer effect is more significant on soils with low yield and phosphorus deficiency. Mineral potassium fulvic acid can significantly improve soil water content. Water effect can improve the drought resistance of green plants.

2. It is not necessary for crops to use mineral potassium fulvic acid to have significant actual effects.

According to the data, the sensitivity factors of various crops to mineral potassium fulvic acid are different, and they are mainly divided into the following categories:

1. Particularly sensitive crops: cabbage, radish, tomato, potato, beet, sweet potato, etc.

2, more sensitive crops: fruit trees, corn, rice, wheat, millet, sorghum, naked oats, etc., as well as various fruit trees.

3. Common crops with sensitivity: cotton, mung bean, kidney bean and other legume crops, maybe legume crops themselves can fix nitrogen, etc.

4. For insensitive crops, if it is sprayed, it will also have corresponding practical effects.
