Powder water-soluble fertilizer, as a type of water-soluble fertilizer, can be mainly divided into the following types based on nutrient composition and functional characteristics:

1. Water soluble fertilizer with a large amount of elemental powder

Core components: Nitrogen (N), phosphorus (P ₂ O ₅), and potassium (K ₂ O) are the main nutrients, and the proportion is adjusted according to crop needs.

Subdivision type:

High nitrogen type: With a high nitrogen content, it is suitable for crop seedling and rapid growth periods (such as the early stage of leafy vegetables), promoting stem and leaf growth, increasing leaf area and photosynthetic efficiency.

High phosphorus type: Rich in phosphorus content, suitable for flower bud differentiation, flowering and fruiting period (if before the flowering period of the tree), can increase flowering and fruiting rates, and reduce flower and fruit drop.

High potassium type: With outstanding potassium content, it is suitable for fruit enlargement, coloring, and ripening periods (such as grape color transformation period), which helps with fruit enlargement, sugar accumulation, and quality improvement, enhancing resistance to lodging and pests and diseases.

Balanced type: The proportion of nitrogen, phosphorus, and potassium is balanced, suitable for the entire growth cycle of crops, especially for crops with insufficient base fertilizer or high fertilizer requirements.

2. Medium element powder water-soluble fertilizer

Core components: mainly composed of moderate elements such as calcium (Ca), magnesium (Mg), and sulfur (S).

Features:

Calcium element: enhances cell wall toughness, improves disease and pest resistance, and prevents fruit cracking (such as tomatoes and apples).

Magnesium element: As a component of chlorophyll, it participates in photosynthesis and promotes substance metabolism.

Sulfur element: participates in protein synthesis and affects crop quality and yield.

3. Trace element powder water-soluble fertilizer

Core components: containing trace elements such as boron (B), zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), molybdenum (Mo), etc.

Features:

Supplementing the deficiency of trace elements in soil and correcting crop nutrient deficiencies (such as zinc deficiency in citrus and boron deficiency in strawberries).

Improve crop yield and quality, such as enhancing fruit color and improving taste.

4. Water soluble fertilizer containing amino acid powder

Core components: mainly composed of free amino acids, chelating various trace elements or adding large amounts of elements.

Features:

Amino acids can be directly absorbed by crops, participate in metabolism, and enhance stress resistance (such as drought resistance, cold resistance, and salt alkali resistance).

Promote root growth, enhance nutrient absorption capacity, and improve the quality of agricultural products (such as better vegetable taste and extended shelf life).

5. Water soluble fertilizer containing humic acid powder

Core Ingredients: Humic acid as the main raw material, combined with nitrogen, phosphorus, potassium, and trace elements.

Features:

Improve soil structure, enhance water and fertilizer retention capacity, and promote soil microbial activity.

Reduce nutrient fixation and loss, improve fertilizer utilization efficiency, and stimulate crop root growth.

6. Water soluble fertilizer containing alginate powder

Core components: Extract alginate from seaweed, add nitrogen, phosphorus, potassium, and trace elements.

Features:

Containing bioactive substances such as seaweed polysaccharides and phenolic polymers, it stimulates crop growth and improves stress resistance (such as cold resistance, drought resistance, and disease resistance).

Improve soil particle structure, increase air permeability and water retention, and enhance the quality and yield of agricultural products.

Application scenarios and advantages

Applicable crops: Widely used in economic crops such as vegetables, fruit trees, flowers, tea, as well as field crops.

Application method: It can be applied by flushing, drip irrigation, spraying or soilless cultivation to achieve water fertilizer integration and improve fertilizer utilization efficiency (up to 80% -90%, traditional compound fertilizer only 30% -40%).

Core advantages: Strong solubility, fast absorption, precise nutrient content, reduced soil pollution, in line with the development needs of modern agriculture for high efficiency and environmental protection.
