Potassium Humate Flake black color from China
Product Features
The powder, flake and granular forms of potassium humate differ mainly in the following aspects:
1.Physical properties
- Powder: fine texture, large specific surface area, black powder appearance, good fluidity, but easy to raise dust.
- Flake: thin flake, with certain flexibility, less likely to raise dust than powder, but flakes may stick to each other.
- Granular: regular or irregular particles, with a certain range of particle size, good fluidity and dispersibility, not easy to agglomerate and raise dust.
2.Solubility
- Powder: due to the large specific surface area, the contact area with water is large, the dissolution speed in water is fast, and nutrients can be released quickly.
- Flake: the dissolution speed is slower than that of powder, and it takes a certain amount of time for water to penetrate into the flake, and the nutrient release speed is also slightly slower.
- Granular: the dissolution speed is between powder and flake, the surface of the particle first contacts with water and dissolves, and as the dissolution proceeds, the internal nutrients are gradually released.
3.Application characteristics
- Powder: Suitable for fertilization methods such as foliar spraying and drip irrigation that require high solubility and fineness of fertilizers, and can be quickly absorbed by plants. It is also commonly used for soil improvement and can be evenly mixed into the soil.
- Flake: It can be used for fertilization on the soil surface, which can slowly release nutrients and continuously provide nutrition for plants. It is more suitable for some scenes that require long-term fertilization, such as fertilization of landscape plants.
- Granular: It is convenient for mechanical fertilization, such as fertilization by seeder or fertilizer spreader, and can accurately control the amount of fertilizer. It is widely used in field crop planting and is also suitable for situations where fertilizers need to be applied to deeper layers of the soil.
4.Storage and transportation
- Powder: Pay attention to moisture-proof during storage, because it has strong hygroscopicity and is easy to agglomerate. During transportation, it is also necessary to prevent dust and loss caused by damage to the packaging.
- Flake: It is easier to store and transport than powder, and is not easy to deform or break due to extrusion, but it is also necessary to prevent moisture and adhesion.
- Granular: It is easy to store and transport, not easy to break and clump, has relatively low requirements for packaging, and can adapt to different storage and transportation conditions.
Application
Potassium humate tablets are suitable for a variety of crops. Here are some common examples:
- Grain crops: In rice cultivation, potassium humate can slowly release nutrients, provide long-term support for rice growth, help enhance rice resistance, and improve yield and quality. For wheat, it can improve soil structure, make wheat roots more developed, and improve wheat resistance to drought and pests and diseases.
- Cash crops: The use of potassium humate in cotton cultivation can promote the growth and development of cotton, make cotton plants strong, and increase the number of bolls and fiber length of cotton. In rapeseed cultivation, it can increase the oil content of rapeseed, while enhancing the cold resistance of rapeseed, so that it can grow better in low temperature environments.
- Fruit and vegetable crops: After applying potassium humate to fruit trees such as apples and pears, it helps the fruit to swell, improve the color and taste of the fruit, and increase the sweetness and vitamin content of the fruit. In the cultivation of vegetables such as tomatoes and cucumbers, it can promote the differentiation of flower buds and increase the fruit setting rate, while also improving the quality of vegetables and making them more resistant to storage and transportation.
