In today's era when agricultural production is moving towards high - efficiency and precision, the choice of fertilizers is of utmost importance. As an important member of the Medical devices family, granular water - soluble fertilizer has gradually become the new favorite of many farmers and planting enterprises due to its unique advantages. What makes it so attractive? And how should it be used correctly? Let's take an in - depth look.

Definition and Characteristics of Granular Water - Soluble Fertilizer

Granular water - soluble fertilizer is a physical form of water - soluble fertilizer, belonging to the category of solid water - soluble fertilizers. Unlike the common powdered water - soluble fertilizers, it presents in a granular form. These granules are usually processed through special techniques, having good stability and fluidity. In terms of composition, granular water - soluble fertilizer is also a multi - element compound fertilizer, rich in macronutrients such as nitrogen, phosphorus, and potassium. It can also be added with medium - elements such as calcium, magnesium, and sulfur, as well as micronutrients such as iron, zinc, boron, and molybdenum according to the needs of different crops. Meanwhile, some products will be added with functional substances such as humic acid and amino acids. For example, the effervescent small - granular water - soluble fertilizer(EFFER) produced by Huayi Hanzhong provides comprehensive nutrition for crop growth.

Its most remarkable characteristic lies in its dissolution performance. Although it does not dissolve instantaneously like powdered water - soluble fertilizers, granular water - soluble fertilizer can dissolve quickly and completely in water under suitable conditions to form a uniform fertilizer solution. It not only has the characteristic of being easily absorbed by crops like ordinary water - soluble fertilizers but also has unique advantages due to its granular form. For example, during transportation and storage, granular water - soluble fertilizer is not prone to caking and dampness, which is convenient for management. During fertilization operations, it is more convenient for accurate measurement and spreading, reducing human errors.

Core Advantages of Granular Water - Soluble Fertilizer

Both Long - lasting and Quick - acting Fertilizer Effects

The relatively slow dissolution of granular water - soluble fertilizer gives it a certain persistence in fertilizer effect. In the case of a long crop growth cycle, one application can continuously release nutrients over a period of time to meet the nutritional needs of crops at different growth stages. At the same time, the dissolved nutrients can be quickly absorbed and utilized by crops, achieving a perfect combination of long - lasting and quick - acting fertilizer effects. For example, in fruit tree planting, applying granular water - soluble fertilizer in spring can provide timely nutrient support for the germination and flowering of fruit trees, and it can also continuously supply nutrients during the subsequent fruit - setting and fruit - expansion periods, ensuring the healthy growth and high yield of fruit trees.

Convenient and Efficient Application

Compared with liquid water - soluble fertilizers and powdered water - soluble fertilizers, the application methods of granular water - soluble fertilizers are more flexible and diverse. In addition to being dissolved and precisely fertilized through drip irrigation and sprinkler irrigation systems like other water - soluble fertilizers, it can also be directly spread, applied in strips, or applied in holes. In some farmlands without irrigation facilities or in large - area and complex - terrain planting areas, directly spreading granular water - soluble fertilizer can greatly improve the fertilization efficiency and save labor costs. Taking corn planting as an example, when sowing, the granular water - soluble fertilizer is sown together with the seeds, and there is no need for complicated water and fertilizer management later to meet the nutritional needs of corn in the early growth stage.

Improving the Soil Environment

Many granular water - soluble fertilizers are added with functional components such as humic acid and microbial agents. Humic acid can improve the soil structure, increase the soil aggregate structure, improve the water - retaining and fertilizer - retaining capacity of the soil, and alleviate the problem of soil compaction. Microbial agents can regulate the soil microbial community, inhibit the growth of harmful pathogens, and enhance the biological activity of the soil. The long - term use of granular water - soluble fertilizer helps to create a good soil ecological environment and create favorable conditions for crop growth. For example, in vegetable greenhouses that have been continuously cropped for many years, the use of granular water - soluble fertilizer containing humic acid makes the soil more loose and breathable, the roots of vegetables grow robustly, and the incidence of pests and diseases is significantly reduced.

Wide Applicability

Granular water - soluble fertilizer is suitable for a variety of crops and planting scenarios. Whether it is food crops such as rice, wheat, and corn, or high - economic - value fruits, vegetables, flowers, and Chinese medicinal materials, it can exert a good fertilizer effect. At the same time, in different planting modes such as field planting, greenhouse planting, and soilless cultivation, granular water - soluble fertilizer can meet the nutritional needs of crops through reasonable application methods. For example, in apple orchards in the north, granular water - soluble fertilizer can be applied as a base fertilizer in autumn to lay the foundation for the growth of fruit trees in the coming year. In tea gardens in the south, it can be spread during the growth season of tea trees to promote the germination and growth of tea leaves.

Usage Methods and Precautions of Granular Water - Soluble Fertilizer

Usage Methods

• Dissolved Application: Dissolve the granular water - soluble fertilizer in water according to a certain proportion, stir evenly, and then apply it through drip irrigation, sprinkler irrigation, or drenching. This method is suitable for crops and planting scenarios with high - precision requirements for nutrient supply, such as greenhouse vegetables and strawberry planting. During the dissolution process, appropriate stirring or increasing the water temperature can be carried out to accelerate the dissolution speed.
• Direct Spreading: In the early stage of crop growth or in the rainy season, the granular water - soluble fertilizer can be directly spread on the soil surface. When spreading, pay attention to uniform distribution to avoid excessive local fertilizer concentration, which may cause seedling burning. For example, after transplanting rice, the granular water - soluble fertilizer can be evenly spread while there is water in the field to promote the tillering of rice.
• Strip or Hole Application: Before sowing or transplanting, apply the granular water - soluble fertilizer in the planting ditch or hole and then cover it with soil. This method can concentrate the fertilizer around the roots of crops, improve the fertilizer utilization rate, and is suitable for transplanted crops such as fruit trees and seedlings.

Precautions

• Control the Application Amount: Reasonably determine the application amount of granular water - soluble fertilizer according to the type of crop, growth stage, and soil fertility status. Excessive application will not only cause fertilizer waste but also may lead to soil salinization, environmental pollution, and other problems. For example, during the peak growth period of vegetables, the application amount per mu is generally controlled at 15 - 20 kilograms each time.
• Avoid Mixing with Alkaline Substances: Granular water - soluble fertilizers are mostly weakly acidic. Mixing them with alkaline substances will cause chemical reactions and reduce the fertilizer efficiency. Therefore, during the use process, avoid mixing with alkaline fertilizers or pesticides such as plant ash and lime.
• Storage Conditions: Granular water - soluble fertilizer should be stored in a dry, cool, and ventilated place, away from direct sunlight and humid environment. Improper storage may cause the granules to cake, affecting the dissolution performance and fertilizer efficiency.

Market Prospect of Granular Water - Soluble Fertilizer

With the acceleration of the agricultural modernization process, the concepts of precise fertilization and green agriculture have become deeply rooted in people's hearts. Granular water - soluble fertilizer, with its own advantages, has shown a rapid growth trend in market demand. More and more farmers and planting enterprises have begun to realize the important role of granular water - soluble fertilizer in increasing crop yield, improving crop quality, and protecting the soil environment.
