What are the differences between water-soluble fertilizer and compound fertilizer?

What is water-soluble fertilizer? What are the characteristics of water-soluble fertilizer?

• It is a quick-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water and can be The roots and leaves of crops directly absorb and utilize it. The application of water and fertilizer at the same time, using water to carry fertilizer, has achieved
• Integrated with water and fertilizer, its effective absorption rate is more than double that of ordinary chemical fertilizers, reaching 80%-90%;
• Moreover, the fertilizer effect is fast and can meet the nutritional needs of high-yielding crops during the rapid growth period. With drip irrigation system
• The water requirement is only 30% of that of ordinary chemical fertilizers, and the fertilization operation requires almost no labor, which greatly improves the efficiency of fertilization.
• Save labor costs.

What is compound fertilizer?

• Compound fertilizer has many types of nutrients. One application of compound fertilizer can supply at least two crops at the same time.
• More than one major nutritional element. For example, ammonium phosphate does not contain any useless by-components, and its anions and cations are the main nutrients absorbed by crops.
• The nutrient distribution of this kind of fertilizer is relatively uniform. After being formed into particles, compared with powdery or crystalline unit fertilizers, it has a tight structure, even nutrient release, and stable and long-lasting fertilizer effect. Because there are few by-products, it has little adverse impact on the soil.

What are the main differences between water-soluble fertilizers and compound fertilizers?

The main difference between water-soluble fertilizer and compound fertilizer 1: Nutrient composition

• Water-soluble fertilizer refers to a compound fertilizer that is completely soluble in water. The form is mainly divided into solid and liquid. The nutrient content is divided into macro elements, medium elements and trace elements. Water-soluble fertilizers containing amino acids, humic acid and other functional water-soluble fertilizers are also commonly available on the market. fertilizer.
• There are not only many types of water-soluble fertilizers, but also various ratios, such as balanced fertilizers with balanced nitrogen, phosphorus and potassium ratios, high nitrogen fertilizers, high potassium fertilizers and high phosphorus fertilizers. At the same time, the fertilizers themselves also include various medium fertilizers that play a key role in the growth of different crops. trace elements,
• Although traditional compound fertilizers contain two or more elements, their main components are only nitrogen, phosphorus and potassium, and their formulas and nutrients are relatively single.

Difference #2: The method and dosage of water-soluble fertilizer and compound fertilizer are different.

• Water-soluble fertilizers are used in a wide range of areas and are suitable for almost all regions in my country. The main application methods are foliar spraying, drip irrigation under the film, root flushing and mountain sprinkler irrigation. The best fertilizers can be formulated according to the characteristics of the planting environment in different regions. Application method, unlike compound fertilizers which must be applied completely below the soil where crops are grown.
• Water-soluble fertilizers are usually concentrated powders or liquids, and the usage amount is generally small. Taking ordinary balanced water-soluble fertilizers as an example, if used in flushing applications, the amount required per acre of land is only about 5KG, while the use of compound fertilizers requires at least 40KG. about.

Difference 3: Water-soluble fertilizers and compound fertilizers have different effects.

• Water-soluble fertilizers are mainly used as top-dressing fertilizers for crops. The difference from other traditional top-dressing fertilizers such as urea is that water-soluble fertilizers are quick-acting fertilizers that are absorbed quickly by crops. However, the duration of the effect after application is relatively short, and it is only suitable for the needs of crops during their growth period. Peak period of obesity.
• Compound fertilizers are generally used as initial base fertilizers for planting. Water-soluble fertilizers have a high absorption and utilization rate. According to experiments, if the application method is proper, it can generally reach about 90%, and the highest is more than 95%, which is almost all absorption. However, traditional compound fertilizers have the highest absorption and utilization rate during crop growth. Only about 60%.

What are the advantages of water-soluble fertilizers compare to normal compound fertilizer?

Difference 1: Water-soluble fertilizer is fully nutritious and has significant fertilizer effect.

• Compared with traditional compound fertilizers, the biggest advantage of water-soluble fertilizers is that they contain various nutrients required by different crops during the growth process, such as iron, manganese, zinc, copper, calcium, etc
• Because most of the nutrients contained in traditional compound fertilizer formulas are only three types: nitrogen, phosphorus, and potassium, which are not enough to meet the basic needs for the growth of most economic crops.
• Water-soluble fertilizers can not only remove specific nutrients, but also greatly help improve crop quality and reduce physiological diseases. Therefore, water-soluble fertilizers are gradually used in the planting of economic crops in various places, with remarkable results.

Difference 2: Water-soluble fertilizer is energy-saving, environmentally friendly and has high utilization rate.

• Regarding the production and use of water-soluble fertilizers, the degree of pollution to the environment is lower than that of compound fertilizers. Regular water-soluble fertilizer manufacturers must have a standard production pollution purification system. Coupled with advanced production technology, the pollution generated becomes very little; the metal elements and chlorides contained in water-soluble fertilizers are less than traditional compound fertilizers. Avoid causing soil nutrient imbalance, structural damage, etc.
• Water-soluble fertilizer not only saves agricultural water during the application process, but also greatly reduces the investment of human resources, which is time-saving and efficient. Because water-soluble fertilizers can be used in a variety of ways according to different crops, the fertilizers can be directly contacted with the crops to the maximum extent, reducing the waste of fertilizers, so the utilization rate is much higher than that of traditional compound fertilizers.
• To sum up, water-soluble fertilizer is one of the most popular new fertilizers at present. Although it has significant advantages over traditional compound fertilizers in terms of composition, fertilizer efficiency and utilization rate, the current water-soluble fertilizer market in my country is still in its infancy, so the terminal Users should be cautious when purchasing water-soluble fertilizers.

What should you pay attention to when fertilizing with water-soluble fertilizer?

So, we have introduce a lot of difference between compound fertilizer and water-soluble fertilizer, now let us talk about what are the things to be taken care of during the fertilization process of water-soluble fertilizers, in order to achieve the best results, it is necessary to combine the characteristics of water-soluble fertilizers and master certain fertilization techniques.

1. Avoid direct flushing and use secondary dilution method.

Because water-soluble fertilizers are different from general compound fertilizers, farmers cannot apply them conventionally.
The method of fertilization causes uneven fertilization, burning of seedlings and root damage, weak seedlings, secondary thinning, etc. The release ensures uniform fertilizer flushing and improves fertilizer utilization.

2. Strictly control the amount of fertilizer applied.

Water-soluble fertilizers have higher nutrient content than ordinary compound fertilizers, and their dosage is relatively small. Because of its strong quick-acting effect, it is difficult to persist in the soil for a long time. Therefore, the amount of fertilizer must be strictly controlled to avoid fertilizer loss, which will reduce the economic benefits of fertilization and fail to achieve the goal of high yield, high quality and high efficiency.

3. Try to use it alone or mix it with non-alkaline pesticides.

For example, when vegetables suffer from nutrient deficiencies or poor root growth, many farmers use the method of spraying water-soluble fertilizers to alleviate the problem. We would like to remind farmers that water-soluble fertilizers should be applied alone or mixed with non-alkaline pesticides to avoid metal ions reacting and precipitating, causing leaf fertilizer damage or phytotoxicity damage.
